摘　　要：在一体式MBR处理高浓度有机废水研究的基础上 ,针对高氨氮城市小区生活污水进行中试研究。着重研究了不同运行状况下处理效果、影响因素及膜通量的衰减规律。试验表明 :通过增设泥水回流和缺氧区可将氨氮去除率从60 %提高到 95 %以上 ,在进水CODCr为 3 3 0mg L、NH3为 10 0mg L时 ,出水CODCr和NH3分别低于 2 5mg L、5mg L ,且其它指标均达到生活杂用水水质标准 (CJ2 5 1 89)。Based on the treatment of high concentration organic wastewater by a submerged membrane bioreactor,a pilot study is conducted to treat domestic wastewater of high ammonia-nitrogen in a housing estate,which emphasizes on the effect of the treatment and the influence factors under different conditions as well as the law of membrane flux attenuation.The study shows that the removal rate of ammonia-nitrogen(NH 3-N) can be increased from 60% to 95% by adding sludge return and anoxic zone.When COD Cr and NH 3 of the influent are 330 mg/L and 100 mg/L,COD Cr and NH 3 of the effluent are less than 25 mg/L and 5 mg/L respectively,whose other indexes can also meet the grey water standard (CJ25.1-89).
