摘　　要：针对洗浴废水水质污染程度轻、水量稳定、便于处理的特点,采用混凝预处理、活性炭吸附、沸石交换和膜滤组合工艺进行处理.混凝沉淀过滤预处理主要去除大部分悬浮物和部分有机物,并将浊度降低到20 NTU以下,避免后续设备的堵塞;活性炭吸附将CODMn和LAS等有机污染指标降至处理目标;90%以上的氨氮主要通过沸石交换去除,最后采用膜滤工艺去除水中99%以上的细菌、大肠杆菌和残余浊度.结果表明,出水满足国家饮用水标准.该处理流程充分考虑了洗浴废水水质特点和各处理单元处理特性,经有机组合成整套设备,是合理和可行的.Generally bathing wastewater is mildly polluted and the quantity is abounding, so it is regarded to be convenient for treatment and reuse. The re-clarified water that match potable water criteria not only can relieve the pressure of water supply, but can save run-costs for bathing industry itself. According to the characteristics of bathing wastewater, coagulation-settlement, filtering, active carbon adsorption, zeolite ion-exchange and uhrafiltration membrane are adopted. The coagulation-settlement and filtering process aim at most suspension and part of organic pollutants in wastewaster, so jams can be eliminated after this process. The active carbon can absorb major organic compounds especially LAS （Linear Aion Surface active agent） so as to reach treatment targets. Over 90 percent of ammonium is removed by zeolite through ion-exchange. As the last process, uhrafihration membrane can wipe off over 99 percent of bacterium and turbidity remained. Results indicate that the outflow meets the potable water criteria. Based on wastewater characteristics and unit operating equipments, this process is proper and feasible.
