In the clothing process, there is a special process - clothing washing process, with people's different requirements for clothing, this washing process has gradually been paid attention to, and separate, that is, water washing plant. Now because the effect of washing water is more and more popular, it has caused a more concerned environmental protection problem, and the development of clothing washing inevitably forms washed sewage. Clothing washing can be divided into a number of types, it is not necessary to elaborate, mainly the wastewater formed by the respective can use clothing washing wastewater decolorization agent, for the type of wastewater has a better treatment effect.
At present, the domestic dyeing clothing washing wastewater treatment methods are mainly biochemical methods, and some also connect chemical methods with it. The same is basically true abroad. Due to the addition of various chemical raw materials and supplementary dyeing processes, it increases the difficulty of biochemical treatment. Our company recommends the chemical flocculation + biological contact oxidation + coagulation treatment method, the treated effluent can fully meet the discharge standard. The coagulation tank only needs to add the clothing washing wastewater decolorizing agent and coagulant aid PAM, and the polymer generated by the reaction settles down to clarify the wastewater, and also has a great effect on the reduction of the color of clothing washing, and can remove a lot of COD, ammonia nitrogen and phosphorus.
Clothing washing decolorizer is generally added between 100-1000ppm/T, which greatly reduces operating costs for enterprises, and the water quality is clear and bright. Compared with the traditional use of polyaluminum chloride, the use of decolorizer not only reduces the cost of agents, but also greatly improves the processing capacity, which is more intuitive and effective for enterprises to bring benefits.
