摘　　要：某液晶面板厂的高含氟高硬度废水处理厂的进水分为含氟废水及有机废水两股,含氟废水经过混凝沉淀+MBBR硝化预处理,降低硬度、F-及NH_(3)-N浓度后与有机废水混合,再采用生化处理+臭氧高级氧化+曝气生物滤池+高效沉淀+消毒组合工艺处理,最终出水水质稳定达到地表水Ⅳ类标准。该项目规模为6×10^(4) m^(3)/d,吨水投资约5935元/m^(3),单位占地面积为0.619 m^(2)/(m^(3)·d^(-1))。The high fluorine and high hardness influent of a wastewater treatment plant in a liquid crystal panel factory includes fluorine containing wastewater and organic wastewater.The fluorine containing wastewater is pretreated by coagulation,precipitation and MBBR nitration to reduce the hardness,F-concentration and ammonia nitrogen,and then mixed with the organic wastewater.The mixed wastewater is eventually treated by a combined process consisting of biochemical treatment,ozone advanced oxidation,biological aerated filter,high efficiency precipitation and disinfection.The final effluent quality stably reaches the requirements of surface water classⅣlimitations.The capacity of this plant is 6×10^(4) m^(3)/d,the investment is approximately 5935 yuan/m^(3),and the footprint area is 0.619 m2/(m^(3)·d^(-1)).
