摘　　要：文章依托广东省佛山市某淡水鱼塘养殖废水的处理,针对淡水水产养殖废水水质水量波动大、碳氮比低、悬浮物含量高等特点,采用高效沉淀池和反硝化滤池组合工艺对水产养殖废水进行处理,实现脱氮除磷及去除SS。结果表明,该组合工艺出水的COD_(Mn)、SS、NH_(4)^(+)-N、TP和TN平均浓度分别为8.82 mg/L、15.98 mg/L、0.73 mg/L、0.13 mg/L和2.25 mg/L,出水水质均达到DB44/2462—2024《水产养殖尾水排放标准》。因此,该组合工艺用于水产养殖废水处理,对污染物具有较好的去除能力。Based on the treatment of aquaculture wastewater from a freshwater fish pond in Foshan,Guangdong,this paper adopts the combined process of high-efficiency sedimentation tank and denitrification filter to treat aquaculture wastewater,which has the characteristics of large fluctuation of water quality and quantity,low carbon to nitrogen ratio and high content of suspended matter,so as to achieve nitrogen,phosphorus and SS removal.The results show that the average concentrations of CODMn,SS,NH_(4)^(+)-N,TP and TN in the effluent are 8.82 mg/L,15.98 mg/L,0.73 mg/L,0.13 mg/L and 2.25 mg/L,respectively.The effluent quality meets DB44/2462-2024 Aquaculture Tail Water Discharge Standard.Therefore,the combined process is used for aquaculture wastewater treatment,and has a good removal capacity for pollutants.
