摘　　要：对比了混凝沉淀+微滤装置和逆流共聚气浮装置对家庭漂洗废水的处理效果。结果表明,PAC的混凝效果优于PFS;经两种装置处理后,出水均澄清,浊度均为10 NTU左右,BOD5<12 mg/L,氨氮<7 mg/L;但混凝沉淀+微滤装置占地面积大、不易设备化集成、滤网易堵塞,而逆流共聚气浮装置紧凑易集成,具有良好的应用前景。Rinsing wastewater reuse research attempted to develop a simple is a common approach to conserve water in households. This treatment technology and equipment for household rinsing wastewater reuse. The effects of the two kinds of devices, coagulation sedimentation ＋ microfiltration and countercurrent air floatation, were studied. It was showed that PAC had better coagulation effect in corn- parison with PFS. The effluents of the two treatment processes were both clear with turbidity around NTU, BODs 〈 12 mg/L, and ammonia nitrogen 〈 7 mg/L. However, the coagulation sedimentation microfiltration device required 10 ＋ a large area and was difficult to integrate into equipment. It also showed tendency of blocking. The countercurrent air floatation device was compact, easy to integrate and demon- strated a good application prospect.
