摘要
采用上流式曝气生物滤池(UBAF)和连续微滤分离膜(CMF)组合工艺,对生活污水进行处理后回用。UBAF-CMF工艺对COD_(cr),BOD_5的去除率超过95%,对SS和NH_3-N去除接近100%。出水中BOD_5与COD_(cr)分别低于10mg/L和40mg/L,SS低于3mg/L,浊度小于0.5NTU,色度小于5度,TP低于0.5mg/L,NH_3-N低于2mg/L。系统运行结果表明生活污水经该组合工艺处理后,出水水质优良,符合生活杂用和市政杂用的要求。
The domestic wastewater was treated and reused by a combined process of Up -flow biological aerated filter (UBAF) and continuous micro filtration (CMF). The removal efficiencies of CODcr,BOD5 are beyond 95%, and SS, NH3 - N are removed about 100%. To the treated wastewater, BOD5 and CODcr is less than 10mg/L and 40mg/L, respectively, SS is smaller than 3mg/L, turbidity is smaller than 0.5NTU, color is no more than 5, TP is less than 0.5NTU, and NH3 - N is less than 2mg/L. The effluent quality of UBAF - CMF treatment system is good, and the treated wastewater can meet the domestic reuse and municipal reuse.
