With the deepening of the process of industrialization, global environmental pollution is increasingly destroying the ecological balance of the Earth's biosphere formed hundreds of millions of years, and pose a threat to the living environment of human beings. According to the State Environmental Protection Administration of the status quo of China's water pollution statistics and surveys, our rivers, lakes and coastal watershed has generally subject to different degrees of pollution, worsening trend showing the whole, the main factors aggravating the pollution of industrial wastewater and domestic sewage . Textile industry in the production process emit large quantities of waste water and waste pollution on the environment, in which the production process wastewater discharge dyeing industry to address serious environmental pollution. Guangzhou Fu students focused on environmental Xingtan dyeing wastewater treatment works (3600m3 / d): dyeing wastewater biological treatment of traditional aerobic and anaerobic biological treatment of printing and dyeing industry can not meet the needs of manufacturers of printing and dyeing wastewater treatment in recent years, mainly again developed two processes: an aerobic an anaerobic contact process biochar an aerobic and anaerobic processes turntable. Anaerobic an aerobic one biochar contact: For CODCr 800 a 1 000 mg / l of dyeing wastewater dyeing wastewater treatment Pharmacy, use this treatment process, the treatment effect can be achieved national emission standards, and then a little further processing can be returned with sludge system tends to balance itself. At present, there are already a number of production plants using the process of dyeing wastewater treatment company, the longest run of more than five years, the treatment effect is stable, but never efflux sludge, also did not find excessive growth of anaerobic sludge tanks. An aerobic anaerobic rotating biological: the process of anaerobic and aerobic sludge separated from each reflux device, the entire system all the sludge back to the narrow biological oxygen turntable. The process of COD, color removal, etc. are up more than 70%. Appropriate flocculant dosing trace measured CODCr, color removal rate can be increased by 15% to 20%. Guangzhou Fu students focused on environmental Xingtan dyeing wastewater treatment works (3600m3 / d): Zhuzhou wastewater, printing and dyeing wastewater treatment, rich students (certified merchants) are provided by the Guangzhou Environmental Protection Engineering Co., rich students. Environmental Protection Engineering Co., Ltd. Guangzhou Fu students (www.fsyhb.com) strong, credible, in Guangzhou environmental monitoring equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the rich into the brilliant students and you work for a better future!
