Currently the main flow dyeing wastewater treatment wastewater treatment processes such more, but most of the main biochemical treatment (1) contact oxidation plant wastewater grill → → → Pumps → acidification regulation pool hydrolysis precipitation → → → contact oxidation Floatation → → decolorization pool aerobic stage of this process emissions standards adopted contact oxidation method, the advantage of simple, easy to run, easy to manage, high resistance to shock loading, low sludge production printing and dyeing wastewater treatment works, its shortcomings are: maintenance problems, biological film growth will fall off at some point affect water quality, easy packing blockage. This process is mainly used to 1500m3 / d following dyeing wastewater treatment. (2) activated sludge wastewater plant grille → → → Pumps → regulation pool hydrolysis acidification activated sludge tank → → → Filter → decolorization coagulating sedimentation tank → discharge standard aerobic stage of this process using the activated sludge process, and its advantages investment moderate, stable operation, good effect of printing and dyeing wastewater treatment cost, easy maintenance, low maintenance and operating costs moderate, mature technology, construction easier. Disadvantages There are prone to sludge bulking sludge bulking can be controlled through proper administration, the amount of sludge produced little more than contact oxidation, slightly larger than the area of ??contact oxidation. This process is mainly used to 2000m3 / d above the dyeing wastewater treatment. (3) pulp dyeing wastewater, wastewater treatment plant wastewater printing grill → regulating pool → → → coagulation reaction tank pump materialized sedimentation tank → → → activated sludge hydrolytic acidification tank → coagulating sedimentation tank → → Filter → decolorization emissions standards Because pulp dyeing and printing wastewater wastewater raw water concentration is relatively high, if directly into the biological treatment, biological treatment system load is high, and therefore need to increase the period prior to biological treatment systems physico-chemical treatment systems. 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 survey processing factory wastewater, 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 is 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): rich students (Figure), manufacturers of printing and dyeing wastewater treatment, Longyan dyeing wastewater provided by Environmental Protection Engineering Co., Ltd. Guangzhou Fu 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!
