摘　　要：研究了循环水冲洗厕所对冲厕污水中氨氮、总氮、COD、浊度以及色度的去除效果。结果表明:在进水氨氮浓度为150~200mg/L、总氮浓度为300~400mg/L、COD_(Cr)为1 200~1 300mg/L、浊度为250~300 NTU、色度为100~150度的条件下,循环水冲洗厕所对氨氮、总氮、COD、浊度、色度的去除率分别为93.5%、65%、94%、97%、96.5%。循环水冲洗厕所对冲厕污水的处理效果达到了初步预期。Ammonia nitrogen, total nitrogen, COD, turbidity and chroma removal rates of toilet-flushing sewage with the treatment of recycling water flushing toilet were investigated. Results showed that the removal rate of ammonia nitrogen, total nitrogen, COD, turbidity and chroma with recycling water flushing toilet were 93.5%, 65%, 94%, 91% and 9 6.5% respectively, when their influent respective concentrations were 150-200 mg/L, 300-400 mg/L, 1 200-1 300 mg/L, 250-300 NTU and 100-150 degrees. The treatment effect of toilet-flushing sewage by recycling water flushing toilet reached the preliminary expectations.
