摘要
采用"曝气生物滤池-超滤-反渗透"工艺处理由污水处理厂排水、滤池反洗水、清净下水以及厂区生活污水混合而成的废水,工程运行结果表明,COD,BOD,氨氮、浊度、电导率的去除率分别为68.06%,77.93%,72.73%,97.37%,99.17%,出水p H为7.2,本系统出水水质满足循环水补水水质要求。
The BAF（biological aerobic filter）-UF（ultra filtration）-RO（reverse osmosis）process is adopted to treat the wastewater, which is consisted of the drain of wastewater treatment plant, the back washing water, the clear drain and plant area sewage. The result shows the removal rate of COD, BOD, NH4＋ -N, turbidity and conductivity reaches 68. 06%, 77. 93%, 72. 73%, 97. 37% and 99. 17% respectively and pH is 7. 2. The output water meets the criteria specified of industrial cir-culating cooling water.
