摘　　要：某原料药企业生产废水COD高、有机磷高成分复杂,设计采用“微电解+两级芬顿+臭氧氧化”的物化组合工艺,以及“水解酸化+A/O”的生化处理工艺。工程实践表明:物化预处理后废水中的总磷去除率达到80%以上,生化处理后总磷可降至5mg/L以下,出水水质达到园区污水厂接管标准,再接人园区污水厂处理。The wastewater produced by a pharmaceutical raw material enterprise has high COD,high organic phosphorus and complex components.The physicochemical pretreatment process of“micro-electrolysis+second-order Fenton+Ozonation”and the biochemical treatment process of“hydrolytic acidification+A/O”were designed.The engineering practice shows that the total phosphorus removal rate is over 80%after physical and chemical pretreatment,and the total phosphorus can be reduced to less than 5 mg/l after biochemical treatment.
