Nansha, Guangzhou: don't cut a tree with a daily output of 1000 tons of paper

go to Nansha and see environmental protection. Don't cut a tree with a daily output of 1000 tons of paper! In the paper project base of Yuexiu Guangzhou Paper Group, located in the Pearl River Management Zone of Nansha, the large paper industry with an annual output of more than 400000 tons actually uses 100% of the pulp from waste paper recycling, which can reduce the wood consumption by more than 950000 cubic meters every year, equivalent to the protection of 22500 hectares of forest land

it was learned in an interview in Nansha District a few days ago that last year's statistical data showed that the comprehensive energy consumption of 10000 yuan output value in this district decreased by 40%; Since Guangzhou launched the Nansha Development in 2002, by the end of last year, the industrial output value of the area has soared by 8 times, but the emission of sulfur dioxide, the main pollutant, has decreased by 40%

in Nansha Pearl River Management Zone, there is the Nansha paper project base of Yuexiu Guangzhou Paper Group. A few days ago, in an interview with this large paper base with an annual output of more than 400000 tons of paper, we did not find a vehicle transporting wood raw materials in and out. Instead, we saw many large trucks loaded with waste paper products in the factory

100% papermaking with waste paper pulping technology

deputy chief engineer Wen leibin of the base told that the base has been replacing the traditional wood pulping and papermaking process with the modern environmental protection papermaking technology of 100% waste paper pulping. On December 27 last year, the project base was officially put into operation, with an average daily output of more than 1300 tons of paper. All of them adopt the international most advanced waste paper deinking production line imported from Germany and Austria to produce high-quality paper by pulping with waste paper products, with an annual output of more than 400000 tons. With this alone, the base can reduce the wood consumption by 950000 cubic meters every year, which is equivalent to the protection of 22500 hectares (equivalent to 330000 mu) of forest land

Wen leibin said that in the traditional papermaking process, strong acids, strong alkalis and other chemicals must be added to achieve the conversion process from wood to pulp, so that the industrial wastewater formed by papermaking contains a variety of highly polluting chemical components; However, after the demand for steel continues to decline due to the growth of waste paper recycling economy, there is no need to add strong acid and alkali, and the chemical pollutants in its wastewater are greatly reduced. The COD emission per ton of paper decreased from 8 kg to 1 kg; The COD emission concentration decreased from 170 mg/L to the current 100 mg/L, reaching the first-class emission standard. It is also the most advanced in the world. At the same time, the comprehensive power consumption per ton of paper in the base has also decreased from 1552 kwh in the old factory in Haizhu District in 2005 to 990 kwh at present, which is equivalent to saving 27600 tons of standard coal every year

the environmental protection department looked at every town and street.

in the interview, it was learned that the environmental protection department also installed a set of 24-hour monitoring system in the plant to realize 24-hour computer monitoring every day. At present, there are 35 sets of 24-hour monitoring systems in Nansha District, aiming at 35 key pollution source enterprises in the district to monitor their pollution discharge all day

the environmental protection department of Nansha District has also built environmental protection monitoring stations in the science and Technology Museum and Wanqingsha here to explain to users simply: four places, including, Huangge Town and Hengli Town, to monitor the atmospheric environmental quality index 24 hours a day. Chenyongchang, deputy director of Nansha District Environmental Monitoring Center, said that to turn on the power switch and let the instrument warm up for 20 minutes, the district is also preparing to build another environmental monitoring sub station near Shiba Chong in Wanqingsha, so as to ensure that every town and street in the district has an environmental monitoring station and realize full coverage of environmental monitoring

the project should pass the environmental protection assessment before entering Nansha.

the head of Nansha District government said that for more than six years since the large-scale development of Nansha, they have always paid attention to the protection of a good natural ecological environment and adhered to the ecological priority strategy. Nansha also formulated the standardized process for environmental protection approval of construction projects to ensure the environmental protection approval before the project is settled. All enterprises and projects entering Nansha must pass strict environmental protection evaluation and acceptance, and meet the national and even international environmental protection standards that are inseparable from their attention to and development of thermal insulation materials. Those environmental protection facilities that do not meet the requirements must not be put into production

in this year's government work report, Nansha District Mayor Luo Zhaoci proposed to focus on promoting the construction of ecological civilization. Nansha District Water Affairs and Environmental Protection Bureau said that this year, the district will vigorously promote three major environmental protection renovation projects, including blue sky, clear water and tranquility, including a comprehensive feasibility study on the promotion of rural domestic sewage treatment demonstration projects. This year, the district government will provide 10million yuan of subsidies, strive to arrange two typical villages in each town and street, pilot the construction of ecological ditches, and strive to complete the transformation of rural domestic sewage treatment system by 2010, so as to achieve the standard discharge of rural domestic sewage
