生物-化学工艺处理粪便污水的生产性试验研究

Study on Treatment of Fecal Sewage by Biological/Chemical Process

针对粪便污水的氮、磷和有机物浓度高的特点,开展了生物—化学工艺处理粪便污水的生产性试验研究。结果表明,当进水的COD、NH3-N、TP分别为(20000～40000)、(500～700)、(30～60)mg/L时,其出水的COD、NH3-N、TP可分别降至(60～100)、(7～15)、(0.3～0.5)mg/L,色度降为20～30倍,出水水质满足《污水综合排放标准》(GB 8978—1996)的一级标准。

Regarding to the high concentrations of nitrogen, phosphorus and organic matters in fecal sewage, the productive research on treatment of fecal sewage by biological/chemical process was performed. The results show that when the influent concentrations of COD, NH3 - N and TP are 20 000 to 40 000 mg/L, 500 to 700 mg/L and 30 to 60 mg/L, the effluent concentrations of COD, NH3 - N and TP can be decreased to 60 to 100 mg/L, 7 to 15 mg/L and 0.3 to 0.5 mg/L respectively. The effluent color is 20 to 30 times. The effluent quality meets the first class criteria specified in the Integrated Wastewater Discharge Standard （ GB 8978 - 1996）.
