摘　　要：针对某光伏企业排放的生产废水的特点,对各工段废水采用分质收集及不同的处理方法。第一、二股废水先采用混凝沉淀预处理,再采用水解酸化/接触氧化工艺处理;第三、四股废水直接汇入水解酸化池;第五股废水采用混凝沉淀法处理。工程实践表明,出水水质达到《污水综合排放标准》(GB 8978—1996)三级排放标准。该系统运行稳定,耐负荷冲击,处理成本低,处理效果良好,COD总去除率为90.7%。The quality-based collection and different treatment methods of wastewater from differ- ent production sections were conducted according to the characteristics of the wastewater discharged by a photovohaic enterprise. The I st and 2nd types of wastewater were treated by coagulation sedimentation, hydrolysis acidification and biological contact oxidation. The 3rd and 4th types of wastewater were directly discharged into hydrolytic acidification tank. The 5th type of wastewater was treated by coagulation sedi- mentation. The engineering practice showed that the effluent quality met the third class criteria specified in Integrated Wastewater Discharge Standard （GB 8978 - resistance to shock loading COD was 90.7%. , low treatment cost and high 1996）. This system had stable operation, high treatment efficiency. The total removal rate of
