采用藻类生物膜工艺处理生活污水,着重考察了对氮、磷的去除效果。结果表明,在静态试验中,当光照度为3 500 lx时藻类生物膜工艺对氮、磷的去除效果明显,对总磷、TN、氨氮、COD的去除率分别达到了98.17%、88%、89%、93.61%。在24 d的动态连续流试验中,当水力停留时间为5 d时藻类生物膜装置处理效果稳定,其中出水TP平均浓度为0.42 mg/L,平均去除率达到了95.38%;出水TN和NH_3-N平均浓度分别为4.22 mg/L和2.16 mg/L,平均去除率分别为83.93%和82.38%;出水COD平均浓度为38.34 mg/L,平均去除率达到了92.31%。出水TP、TN、氨氮和COD浓度均达到了《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一...

The algae biofilm process was used to treat domestic sewage.The removal effects of nitrogen and phosphorus were investigated emphatically.The results show that in the static tests,the removal effects of nitrogen and phosphorus in the algae biofilm process are remarkable when the illuminance is 3 500 lx,and the removal rates of total phosphorus,total nitrogen,ammonia nitrogen and COD reach 98.17%,88%,89% and 93.61 % respectively.In a dynamic continuous-flow experiment of 24 d,the treatment efficiency of algae biofilm device is very stable when H...
