【摘要】 对间歇式活性污泥法对城市生活污水进行了试验研究。在试验中探讨了生物脱氮除磷的规律及对处理效果的影响。结果表明 :在总停留时间控制在 4 5～ 5 5h ,污泥负荷为 0 14～ 0 2 6kg BOD5/ (kgMLSS·d) ,进水BOD594 7～ 135 0mg/l,CODcr186～ 2 6 6 7mg/l,NH4-N15 .0～ 2 5 4mg/l,TP5 6～ 7 1mg/l条件下 ,达到了既去除有机物又能脱氮除磷的效果。出水BOD5浓度在 6 6 3～ 17 0 5mg/l,去除率达 85 %～ 93% ;出水CODcr浓度在 2 2 32～ 4 8 0mg/l,去除率达 82 %～ 88% ;出水NH4-N浓度在 2 83～ 9 83mg/l,去除率达 5 3%～ 87% ,出水TP浓度在 0 1～ 0 4 5mg/l,去除率达 85 %～ 99%。更多还原

【Abstract】 The treatment of municipal wastewater by sequencing batch reactor and the regularity and effects of nitrogen and phosphorus removal from municipal wastewater was studied.The results showed that the removal rate of BoD 5,COD Cr ,NH 3-N and TP was respectively 85%～93%,82%～86%,53%～87%,85%～99%and the effluent concentration of BOD 5,COD Cr ,NH 3-N and TP was partly 5 12～13 62mg/l,10 7～32 2mg/l, 2 83～9 83mg/l and 0 1～0 45mg/l under the conditions of total HRT was 4 5～5 5 ,sludge load was 0 14～0 26kgBOD 5/(kgMLSS·d),the influent concentration of BOD 5,COD Cr ,NH 3-N and TP was partly 94 7～135 0mg/l,186～266 7mg/l,15 0～25 4mg/l,5 6～7 1mg/l.更多还原
