Three samples to interpret the transformation and upgrading of Fuyang paper industry. Fuyang papermaking has a long history. Especially in the 1990s, village run Fuyang No. 2 paper mill (the predecessor of Yongtai paper industry) and other township enterprises developed and produced whiteboard. The production scale was geometrically enlarged, and it became a whiteboard base in China. In the 1990s, after graduating from Zhejiang agricultural raw material industry university, Lu Renwu went to work in Fuyang environmental monitoring station. When he opened the window, he found the Fuchun River, which is also a first-line river scenery. It seems to us that it has a different meaning. He collected water samples from Fuchun River almost every day for 20 years. At that time, the river water was clear to the bottom. By the end of the 1990s, the water began to be turbid and smelly. As soon as the color of the river changed, his eyebrows would tighten. At the same time, Fuyang paper industry has reached its peak, forming an industrial cluster dominated by Chunjiang, Dayuan and Lingqiao industrial functional zones. Fuyang people hesitated and hesitated for the first time: on the one hand, the paper industry has made great contributions to the local economy; on the other hand, the pollution to the environment has affected the drinking water problems of millions of Hangzhou people on both sides of the Strait and downstream. In recent years, Fuyang has successively implemented five rounds of paper-making elimination and shutdown, shutting down 231 enterprises and 423 production lines, reducing production capacity by 3.712 million tons, wastewater discharge by 16000 tons and sulfur dioxide discharge by 2183 tons, in order to restore a modern version of Fuchun mountain. Cod (chemical oxygen demand) emission concentration has been reduced from 100mg/l at the beginning to 80mg/l and 60mg/l. The sixth round of action this year is required to be within 50mg/l. Lu Renwu, who is now the chief of the pollution control section of Fuyang Environmental Protection Bureau, said. Fuyang paper enterprise, if it wants to survive, must transform and upgrade! Sample 1: the paper-making enterprises turned into pollution control experts. From traditional paper-making polluting enterprises to carrying the banner of environmental protection, the Transformation Opportunity of Zhejiang Banqiao Qingyuan Environmental Protection Group took place in 2002. In 2002, Fuyang City formulated a comprehensive environmental improvement plan for Jiangnan area. It plans to build five centralized sewage treatment plants with a total treatment capacity of 750000 tons/day. It also intends to break the single investment pattern of the government and take the road of industrialization and marketization. Zhejiang Banqiao Qingyuan Environmental Protection Group invested 246million yuan to launch the Qingyuan urban comprehensive sewage treatment project. This is Banqiao's first project to get involved in the environmental protection industry. It is also Fuyang's first private public environmental protection infrastructure project built by adopting the boo (i.e. construction, ownership and operation) investment method. It has also won a low interest loan from the German government. With an investment of 246million yuan, the last papermaking project with an annual output of 150000 tons could produce an output value of 6.7 billion yuan. However, I am shocked by the fact that the sewage treatment project is filled with sewage and discharged with clean water. The project itself is not profitable, but it shows us the hope of the paper industry, which can be said to revive the whole industry. The project started construction in november2003 and was put into operation in march2006. The design scale is 150000 tons of sewage per day, with 12.5 kilometers of supporting collection pipes. It is responsible for the collection and treatment of the domestic sewage of more than 10000 residents in the five administrative villages of Chunjiang street and the industrial sewage of 48 surrounding paper-making enterprises. In 2009, Banqiao invested another 65million yuan to take the lead in building a 150000 ton/day tail water advanced treatment, regeneration and reuse project in the city, and the COD emission concentration dropped below 50mg/l. Yu Zhengqi hopes that his model can be copied and become a green industrial chain. Sample 2: paper enterprises introduced pollution control talents. In 2003, Xu Jingjing graduated from university and came to Yongtai paper industry as a talent introduction. My major is environmental engineering. I come to paper-making enterprises for sewage treatment, which is very suitable. She said that at that time, Yongtai invested 52.8 million yuan in the first set of sewage biochemical treatment system in Fuyang paper enterprise, with a daily sewage treatment capacity of 45000 tons. With the continuous development of the enterprise, the pollution control standard is also improving synchronously. At present, the national postdoctoral scientific research workstation, provincial academician workstation and provincial technology center platform under the group company have expressed to Craig Caputo, the North American Regional Product Manager of Bayer materials technology, from the aspects of process flow, equipment configuration, energy consumption and waste Bayer materials technology, the following aspects in the sixth round of papermaking elimination and shutdown in Fuyang City It provided comprehensive guidance on personnel arrangement, invested 15million yuan to implement the remediation and upgrading project, and reduced the annual COD emission by 49.77 tons. Relying on the advantages of talents, as one of the provincial circular economy pilot enterprises, Yongtai paper develops its sidelines such as power generation, heat supply, trade, chemical industry and sewage treatment around the paper industry, and has formed a complete industrial chain. Last year, the company's papermaking capacity reached 550000 tons, and the enterprise's sales output value was about 3billion yuan. Among them, the sales value of chemical industry, power supply, heat supply and sewage treatment exceeded 600million. It can be said that environmental protection has created benefits. Sample 3: the ultra membrane technology used for seawater desalination enables papermaking to achieve zero emission, beautiful Fuyang does not need black GDP. The main target of the sixth round of elimination of backward production capacity in Fuyang City launched this year is the paperboard production line with waste paper as the main raw material and a production capacity of 30000 tons/year or less; A thin packaging paper production line with waste paper as the main raw material and a single approved capacity of less than 7000 tons/year (excluding); When the enterprise approves the technical transformation, it specifies the production lines that should be removed but have not been removed. By 2015, the number of paper-making entrepreneurs will be controlled within 100, and the total discharge of water pollutants in the paper-making industry will be reduced by 40% compared with the 11th Five Year Plan period. It is planned to shut down 60 enterprises during the year. So far, 37 enterprises have dismantled 40 production lines and reduced 770000 tons of backward production capacity. The city's 159 paper-making enterprises included in the scope of renovation and upgrading must be renovated in strict accordance with the acceptance standard for renovation of paper-making enterprises in Zhejiang Province, and finally accepted by the acceptance department one by one. Hangzhou Special Paper Co., Ltd., located in Lushan street, Fuyang, is among them. According to the new requirements of this year, we interviewed five wastewater treatment companies, and finally introduced the ultra membrane treatment technology, which has been used in seawater desalination. Wang Jianye, general manager of the company, said that the investment was 2.15 million yuan. After the first round of biochemical treatment, the sewage will be subjected to simulated transportation test for ultrafiltration treatment. Specifically, the organic matter is filtered first, then enters the ultrafiltration membrane, then passes through the reverse osmosis device, and finally the discharged water can have a minimum COD of 15mg/l. He said that after recycling and recycling, zero emissions will be basically realized. At the same time, enterprises have also tasted the sweetness of developing high-end products. For example, a chemical analysis filter paper with a diameter of only 12.5 cm can be produced by only two domestic enterprises. The product sold for 0.39 yuan, and the profit is much higher than that of ordinary paper
