摘　　要：采用跌水曝气生物膜法进行生活污水处理试验研究。试验结果表明:水力停留时间为3.6h时,进水CODcr、NH4+-N、浑浊度分别在103～162 mg/L、78.16～116.57mg/L、36～66NTU范围变化时,相应平均去除率分别为64.79%、14.2%、84.81%。系统出水DO平均为3.9mg/L。The domestic sewage treatment with drop-aeration bio-film process was preliminarily investigated, and the experiment results was showed, that under experimental condition with HRT for 3.6 hours, the COD and NHa4^＋-N turbidity of influent were changed in the ranges of 103-162 mg/L and 78.16-116.57 mg/L and 36-66NTU respectively, the corresponding average removal rates were 64.79% ,14.2% ,84.81% ,the average concentrations of DO in the effluent wastewater was 3.9 mg/L.
