摘要
采用物化(混凝、电解氧化)/水解/接触氧化工艺处理医药化工废水,处理量为200m3/d,其中高浓度废水COD为30000mg/L,低浓度废水COD为3000mg/L。运行实践表明,电解氧化工艺与水解酸化工艺联用,可明显提高废水的可生化性;接触氧化池对COD的去除率约为70%。整个处理系统对COD的去除率达到95%,出水COD<300mg/L,pH为7.92～8.27,达到《污水综合排放标准》(GB8978—1996)的二级标准。
The physicochemical （coagulation and electrolytic oxidation）/hydrolysis/contact oxidation process was used to treat pharmaceutical and chemical wastewater. The wastewater treatment capacity is 200 m3/d, in which high-concentration COD is 30 000 mg/L, and low-concentration COD is 3 000 mg/L. The treatment practice indicates that the combination of electrolytic oxidation with hydrolytic acidification can improve the wastewater biodegradability obviously. The removal rate of COD in contact oxidation tank is about 70% , and that in the total treatment system is 95%. The effluent COD is less than 300 mg/L and pH is 7.92 to 8.27. The effluent quality reaches the second level criteria specified in the Integrated Wastewater Discharge Standard （ GB 8978 - 1996）.
