两级A/O-混凝沉淀工艺处理树脂废水

摘要

Aimed at the characteristics of wastewater from a resin production company, the process of two-stage A/O coagulation was used .The operation results show that when the influent of COD is 4000~5000 mg/L, the effluent of COD is 150~300 mg/L,the average removal rate is more than 95%. The effluent of the treatment can meet the standard in the discharge standard for municipal wastewater(CJ343-2010).%　　针对某树脂生产企业废水的特点，采用两级A/O-混凝沉淀工艺对其进行处理。运行结果表明：在进水COD为4000~5000 mg/L时，处理后出水COD为150~300 mg/L，平均去除率达到95%以上，系统出水水质达到《污水排入城镇下水道水质标准》(CJ343-2010)的标准。
