Chapter 1 Overview

1.1 Project Background

Zhumadian Municipal Baiyun Paper Co. Ltd. was approved and established by the Zhumadian Municipal Government as a solely state-owned company according to the modern corporate system in August 1999, and the company was restructured with Henan Construction & Investment Company and became the new Zhumadian Municipal Baiyun Paper Co. Ltd. in November 2003. The company has 1,977 employees, with an area of 1,293.2 Mu, fixed assets amounted to 2.1 billion Yuan, and registered capital of 120 million Yuan.

In recent years, Baiyun Paper Co. Ltd. has achieved some results in the fields of production and operation, safety and environmental protection, quality management and so on; the company has gradually grown into an industry leader in Henan Province, which takes the lead in becoming an enterprise with the approval of “four systems”. In Henan Province, the company was identified as the “Provincial Enterprise Technology Center”, the “Henan Provincial Research Center for Energy-Saving and Emission Reduction Engineering Technology in Pulping and Papermaking”, as well as one of the first batch of “Quality Credit Grade AA Enterprises in Henan Province”, it has been awarded with the “Top Ten Enterprises in Paper Industry in Henan Province” for seven consecutive years, and it has received awards of the “Green Enterprise in Henan Province”, the “Water-saving Enterprise in Henan Province”, as well as the national “Ankang Cup” Competition Winner.

The Phase I Project of the company mainly includes a production line for wheat straw caustic soda bleaching and pulping with a capacity of 110adt/d, a supporting alkali recovery production line and a supporting wastewater treatment station with a capacity of 25,000 m3/d, a 2,640 multi-cylinder long mesh culture paper machine with a capacity of 100t/d, as well as four sets of 2,640 eight-cylinder cultural paper machines with the production capacity of 40t/d; the pulping workshop adopted the dry and wet stock preparation, the continuous cooking, the double-row 50m2 vacuum filter washer, the screening system supplied by Ahltrom in Finland, as well as the CEH bleaching process; for the black liquid evaporation, the alkali recovery workshop adopted the five-effect plate evaporator and had complete system for heating, water supply and power generation and a 110 KV substation.

In the Phase II Project of Baiyun Paper Co. Ltd., the production line with 51kt/a refined wheat straw pulp and the production line with 204kt/a cultural paper were newly built, and the pulp production line, which was provided by Austria’s Andritz Company, adopted the ECF elemental chlorine free bleaching process; the paper machine, which was provided by German’s Voith Company, had a machine width of 5,280mm and a operating speed of 1,300m/min and adopted the double shoe press technology, the film-shifting sizing technology and other advanced technologies, and the pulp preparing and approaching system, which was provided by Austria’s Andritz Company, mainly produced high-grade electrostatic copy paper of 60~120 grams/sheet and two-side offset paper; the supplementary construction of auxiliary production facilities and pollution treatment facilities for energy conservation and emission reduction, including the alkali recovery device with a capacity of 230 tds/d, the sewage treatment plant with daily treatment of 48,000 tons, the solid waste incineration boiler of 2x110t/h and the 20 MW coal-fired power station, was completed, and the sewage treatment station adopted the treatment process of “physicochemical treatment+ anaerobic treatment+aerobic treatment+advanced chemical treatment+decolorization” provided by Sweden’s PURAC Company. The project was completed and put into operation in June 2011. The implementation of this project also enables Baiyun Paper Co. Ltd. to become a large modern pulp and paper enterprise with a production capacity of more than 300,000 tons of cultural paper and played a good role in promoting the overall level of the paper industry in Henan Province.

The Environmental Protection Department of Henan Province issued a written reply in the form of Henan File No. [2013] 7 on September 13, 2013, and the reply also required the enterprise to carry out the ECF bleaching renovation of pulping in the Phase I Project.

Currently, the renovation of pulping and bleaching has been completed in the Phase II Project, and the CEH bleaching process failed to be transformed into the ECF bleaching process in the Phase I Project. After it was transformed into the ECF bleaching process in the Phase II Project, the project runs steadily, and the yield, quality and stability of bleached pulp have been improved compared with the traditional bleaching process. At the same time, the effluent volume and pollutants generated in the ECF pulping are substantially lower when compared with the traditional bleaching process.

In view of this, Zhumadian Municipal Paper Co. Ltd. decides to conduct the Phase I technical transformation of the bleaching process and the chlorine dioxide system for 37,000 tons bleached chemical caustic soda wheat straw pulp, so as to replace the original CEH bleaching process with the new elemental chlorine free bleaching process.

This project is a technical upgrading project for cleaner production and environmental protection, and once this technical upgrading project is completed, the original elemental chlorine-containing bleaching process in the Phase I Project can be transformed into the elemental chlorine free bleaching process. When this technical upgrading project is completed, its annual sales revenue should be 138.99 million Yuan, the total amount of profits and taxes is 5.57 million Yuan with little profit, and the economic benefits is slightly less than before, but the completion of the project will completely change the image of pulp and paper mills as large polluters, prevent the generation of dioxin, a carcinogenic chemical, greatly reduce the AOX index, create significant environmental benefits and social benefits, as well as further improve and develop the market competitiveness of the enterprise.

According to the “Guiding Catalogue of Industrial Structure Regulation” (issued in 2011 and revised in 2013), the technical upgrading project belongs to the “development and application of elemental chlorine free (ECF) and totally chlorine free (TCF) chemical pulp bleaching process” in the encouraged category and complies with the requirements of relevant national industrial policies.

According to the “Environmental Impact Assessment Law of the PRC”, the “Management Rules for Environmental Protection of Construction Projects” and the “Directory of Environmental Impact Assessment Management of Construction Projects”, Henan Yuantong Environmental Protection Engineering Co. Ltd. is entrusted by the construction institution to undertake the environmental impact assessment (EIA) of this project. Based on field investigation, research and survey, data analysis and the collection of environmental monitoring data, Yuantong completed the preparation of the “EIA Report on Technical Transformation Engineering Project of 37kt/a Wheat Straw Pulp ECF Bleaching Process of Zhumadian Municipal Baiyun Paper Co. Ltd.”.

1.4 Identification of Impact factors, Screening of Assessment Factors and Assessment Focus

1.4.1 Identification of Environmental Impact Factors

The technical renovation project is located in the Huai River Basin. According to characteristics of the project, this assessment identifies the environmental impact factors during the construction period and operation period of the project.

During the construction period of the technical renovation project, the impacts on atmospheric environment, water environment and acoustic environment are mainly short-term impacts, and these impacts should be terminated with the end of the construction period. There is no newly added land for the project construction, thus the construction work cannot result in the destruction of vegetation, and it almost has no impact on the ecosystem.

During the operation period of the technical upgrading project, the waste gas, waste water, noises and solid wastes generated by the project can adversely affect atmospheric environment, water environment, acoustic environment, soil environment, human health in a long term, and these impacts will be exacerbated under abnormal working conditions and accident conditions. The completion of technical upgrading project can not only increase fiscal revenue, drive the development of related industries and promote local economic development, but also reduce the pollutant production and energy consumption and reduce the production costs and pollution control costs of the enterprise.

The identification of the project’s environmental impact factors is shown in Table 1-1.

Note: 1. AOX (Absorbable Organic Halide) index and dioxin index apply to the use of chlorine bleaching process.

2. The pulp yield shall be calculated on the basis of oven dry pulp.

3. The actual quantity of discharged wastewater per unit product of the pulping and papermaking enterprise should be checked and defined, and it should be calculated on the basis of the sum of the pulp yield of the enterprise and the quantity of purchased commercial pulp.

4. AOX (Absorbable Organic Halide) and dioxin standards aim at the sewage drain outlets of workshops or production facilities.

As described in the above Table, among 304kt/a cultural paper products in the whole plant, 88kt/a (air-dried pulp) shall be self-produce non-wood pulp, which shall comply with the corresponding standard for less than 100,000 tons of products.

After converting the Chinese Standard GB3544-2008 into air-dried pulp, the comparison with the EHS Guiding Standard under the condition of the same unit can be seen in the following Table.

It is important to note that in the EHS Guidelines, cooling water and other clean water are not included in the final quantity of discharged wastewater, but they are included in the GB3544 -2008. In fact, cooling water and other clean water are recycled and utilized by the paper mill, the quantity of discharged wastewater per ton of pulp is usually only 1-2 m3/adt, which will not cause significant changes in the total quantity of discharged wastewater and the effluent quality of the sewage treatment station, therefore, there exits an equivalent basis for the comparison of the EHS Guidelines and the GB3544-2008. In the EHS Guidelines, there is no requirement about dioxin and AOX in the sewage discharge during the non-wood pulping process, and the Chinese standard aims at oven dry pulp; when converting the oven dry pulp in the Chinese standard into air-dried pulp, the conversion coefficient shall be 0.9; in the Chinese standard, AOX and dioxins are detected at the sewage drain outlets of workshops or production facilities. The comparison results show that, except that total nitrogen (TN) and the quantity of discharged wastewater per unit product slightly exceed the EHS Guidelines, China’s GB3544-2008 Standard is more stringent than the EHS Guidelines. The up-to-standard analysis and comparison according to the actual quantity of discharged wastewater of Baiyun Paper can be seen in the section of Cleaner Production.

3.1.5.2 Power Supply

Currently, the plant has a 110/10KV transformer substation, which can provide various workshops with electricity by using 110KV power supplied by Zhumadian City Electricity Company after voltage transformation, and at the same time the enterprise’s existing coal-fired power station has 2×3000KW steam turbines, which can also provide the enterprise with part of the electric power.

3.1.6 Water Supply and Drainage before Technical Upgrading

3.1.6.1 Water Supply

Before the technical upgrading, the total water consumption of the project is 44,201.6m3/d and 15,028,544m3/a, of which the one-time water consumption is 7,795.6m3/d and 2,650,504m3/a, the consumption of reused water is 35,757m3/d and 12,157,380m3/a, and the water volume brought in by raw and auxiliary materials is 649m3/d and 220,660m3/a. There are 17 deep wells in the plant for the time being, of which 13 deep wells can supply water for production, with a water supply capacity of 29,248.8m3/d, so they can meet the need of production.

3.1.6.2 Water Discharge

Before the technical upgrading, the total discharge volume of the whole plant is 22,591 m3/d and 7,680,940m3/a, of which the drainage volume of 37,000 tons/year pulp production line and papermaking is 7,701.1 m3/d and 2,618,374m3/a, the discharge volume of 51,000 tons/year pulp production line and papermaking is 7,089.9 m3/d and 2,410,566m3/a, and the drainage volume of papermaking by using commercial pulp is 7,800 m3/d, which is equivalent to 2,652,000 m3/a. The baseline drainage volume of 37,000 tons/year pulp production line and papermaking is 70.01 m3/t pulp, the baseline drainage volume of 51,000 tons/year pulp production line and papermaking is 47.3m3/t pulp, and the baseline drainage volume of the whole plant’s papermaking by using commercial pulp is 16.7m3/t pulp, according to the “Discharge Standard of Water Pollutants for Pulp and Paper Industry” (GB3544-2008), baseline drainage volume of 37,000 tons/year pulp production line and papermaking exceed the Standard. The enterprise has a self-pulping capacity of 88,000 tons/year, and the rest products rely on commercial pulp, according to this, the upper limit allowable drainage volume is {8.8/0.6×54+（30.4-8.8/0.6）×18}/340=31,600 tons/day, and the lower limit allowable drainage volume is {8.8×54+（30.4-8.8）×18}/340=25,400 tons/day, thus from the foregoing, the drainage volume of the whole plant can meet the Standard and remain at a relatively high level.

Before the technical upgrading, the drainage volume of 37,000 tons/year pulp production line and papermaking is 7,701.1 m3/d and 2,618,374m3/a, of which the drainage volume of the production system is 7,316m3/d and 2,487,440m3/a, the release of clear water is 358.5m3/d and 121,890m3/a, and the drainage volume of domestic sewage is 26.6m3/d and 9,044m3/a. The project’s drainage system diverts wastewater from clean water in the process plant area, and the drainage system has the separate sewerage system for clean water and rainwater and the one for production and domestic sewage. The system for clean water and rainwater is connected by pipe pipelines for direct discharge, and the production and domestic sewage should be sent to the sewage treatment station for treatment through pipelines before discharging outside the plant, and the plant has a discharge outlet, thus the wastewater can be discharged into the Kuiwang River through the sewage networks in the cluster region, finally into the Ru River.

The water consumption and drainage of existing project are shown in Table 3-7, and the water balance analysis is shown in Figure 3-1.
