微电解-JS试剂法处理印染废水的研究

印染废水是一种成分复杂、处理难度大、毒性高的工业废水,对环境危害极大.针对印染废水选择了合适的预处理方式,并建立一种微电解-JS试剂法处理印染废水的工艺.印染废水首先通过酸化絮凝预处理,再利用自制高活性微电解填料协同自行开发的JS试剂处理,最后通过加入石灰调节pH值为9,并进行混凝沉淀,废水色度基本脱除,COD含量降至...

Study on Treatment of Printing and Dyeing Wastewater by Micro Electrolysis JS Reagent Method

Printing and dyeing wastewater is a kind of industrial wastewater with complex composition, difficult treatment and high toxicity, which is harmful to the environment.A suitable pretreatment method is selected for printing and dyeing wastewater, and a micro electrolysis JS reagent process is established to treat printing and dyeing wastewater.Printing and dyeing wastewater was pretreated by acidification and flocculation, and then treated by self-made highly active micro electrolysis filler and self-developed JS reagent.Finally, the pH value of the wastewater was adjusted to 9 by adding lime, and coagulation sedimentation was carried out.The chroma of the wastewater was basically removed, and the COD content was reduced to 79.2 mg/L,and the SS content was reduced to 19.5 mg/L,which met the first class discharge standard of integrated wastewater discharge standard(GW 8978-1996).
