【摘要】 采用混凝—生物接触氧化法处理生活小区废水 ,考察了不同混凝剂用量对COD、NH4 N、SS、TP的去除效果 ,同时研究了生物接触氧化法对COD、NH4 N等的去除以及耐冲击负荷能力。结果表明 ,随混凝剂用量的增加 ,COD、SS、TP的去除率随之增加 ,生物接触氧化法具有较高的抗冲击负荷能力 ,最大NH4 N去除负荷达到 0 5 5kg/ (m3·d) ,最大有机去除负荷达到 4 3 2kg/ (m3·d)更多还原

【Abstract】 Coagulation and biological contact oxidation are investigated to treat sewage. The removal efficiencies of SS、COD、NH 4-N、TP by coagulation, the removal of COD,NH 4-N by biological contact oxidation and the tolerance of load shock are studied. The results show that the removal ratios of SS、COD、NH 4-N、TP increase along with the raise of the dosage of drug and the tolerable shock load rang of biological contact oxidation is wide. The maximum removal rate of NH 4-N loading could reach 0.55 kg/(m 3·d)and COD reach 4.32 kg/(m 3·d).更多还原
