SAF-化学絮凝-微滤膜组合工艺处理高浓度生活污水的试验研究

Study of Domestic Wastewater Treatment with High Concentration Pollutants by SAF-Chemical Flocculation-Micro Membrane Filtration Combined Process

采用SAF-化学絮凝-微滤分离膜组合工艺对高浓度生活污水进行处理。SAF处理系统对污染物的去除效果良好,CODcr,BOD5,SS和NH4+-N的去除率分别为92%,93%,90%和98%。SAF生物处理系统的出水再经化学絮凝和微滤分离膜深度处理后,CODcr,BOD5,NH4+-N,PO43--P的浓度分别低于40 mg/L,10mg/L,4mg/L,0.3mg/L;浊度小于0.5NTU,色度小于10度。试验结果表明该组合工艺处理后的污水水质优良,可满足生活杂用和市政杂用。

SAF-chernical flocculation and micro membrane filtration combined process was adopted to treat the domestic wastewater with high pollutant concentration. The removal efficiencies of CODc,, BODs, SS and NH4-N by SAF treatment system were 92%, 93%, 90%, 98%, respectively. The results showed that the treated effluent water quality of the combined process was good, CODcr, BODs, NH4^＋-N and PO4^3--P were less than 40mg/L, 10mg/ L, 4mg/L, 0.3mg/L, turbidity and color were lower than 0.5NTU and 10 solely, and the treated wastewater could be used for municipal reuse and domestic reuse.
