Wastewater, rich students, papermaking wastewater pollutants by the Guangzhou Environmental Protection Engineering Co., Ltd. Fu students. Wastewater, rich students, papermaking wastewater pollutants are rich students Guangzhou Environmental Protection Engineering Co. (www.fsyhb.com) launched this new upgrade, the above picture is only for reference, please call the contact phone book pages or pictures on request The latest information, contact: Hu large reed. Paper industry is one of the major sectors of the environment. State Department request, to the end of 2000, all industrial pollution sources must meet emissions standards. Pollution solve China's paper industry has become a very urgent task. Currently paper pulp industrial wastewater emissions account for about 10-12% of the national total papermaking wastewater effluent reuse, ranked third; discharge wastewater chemical oxygen demand emissions account for about 40-45% of the national total paper wastewater pollutants, ranking first. Paper industry has become one of the major sectors of the environment. Pulp and paper production wastewater is mainly cooking waste, waste water and paper Whitewater middle of three parts. Pollution load of waste cooking accounts for about 80 percent of all pulp and paper wastewater is the main source of pollution, followed by the middle of the water. White Water back to change technology, has been widely promoted in our country. Large paper machine typically uses a multi-disc filter, SMEs are using flotation tank or disc filter machine white water recovery, so that the paper has been fully Whitewater reuse, and some have achieved a closed loop. White Water pollution control technology has no barriers. Pollution control wastewater digester effluent and the middle is the focus and the difficulties in the paper industry pollution prevention. Rich students Dongguan southern engineered wood pulping and papermaking papermaking wastewater pollution control waste digester, either alkaline or acid pulping, in the international arena, technology already mature. China's paper raw materials, wood products account for a small proportion of the raw material, in the self-pulping, pulp for less than 10%. Domestic wood as raw material chemical pulp mills have been supporting the basic Recovery System, Recovery rate of 90%. Although the recovery is still lower than the international advanced level, but running well. Middle of a small amount of production waste paper pulp bleaching wastewater discharge, due to the traditional three-stage CEH bleaching, although they have not solved the problem of dioxin contamination, but after a two-stage process can also discharge standards.
