摘　　要：根据光伏企业生产废水水质特征,按照分类收集、分质处理原则,将含氟废水经混凝沉淀预处理后再与综合废水合并,采用电催化-混凝沉淀-管式微滤-UASB-AO组合工艺进行处理。运行结果表明,该工艺对光伏企业综合废水中的污染物有较高的去除率,对F^(-)、COD_(Cr)、BOD_(5)、NH_(4)^(+)-N、TN和SS的最终去除率分别达到了89.1%、97.6%、96.5%、90.6%、84.3%和85.3%,出水水质可以达到《电池工业污染物排放标准》(GB 30484—2013)表2新建企业水污染物间接排放标准要求,工程投资共计797万元,运行费用为8.36元/t,通过沼气回收、磁悬浮风机节能技术,每年产生经济效益为34.0万元,为光伏企业生产废水的设计与运行处理提供参考。Based on the quality characteristics of production wastewater from photovoltaic enterprises and the principles of separate collection and treatment,fluorine-containing wastewater was pretreated by coagulation and sedimentation before combing with comprehensive wastewater.The electrocatalysis-coagulation sedimentation-TMF-UASB-AO combination process was used to treat the mixed wastewater.The operation results showed that this process had a high removal rate for pollutants in the comprehensive wastewater of photovoltaic enterprises.The final removal rates of F^(-),COD_(Cr),BOD_(5),NH_(4)^(+)-N,TN,and SS reached 89.1%,97.6%,96.5%,90.6%,84.3%,and 85.3%,respectively.The effluent quality could meet the requirements of Table 2 in the Pollutant Discharge Standards for Battery Industry(GB 30484-2013)for indirect discharge of water pollutants in new enterprises.The total project investment was 7.97 million yuan,and the operating cost was 8.36 yuan/t.Through biogas recovery and magnetic levitation fan energy-saving technology,the annual economic benefit was 340000 yuan,which provided reference for the design and operation of wastewater treatment in photovoltaic enterprises.
