| 摘 要： | 采用四段式接触氧化沟预处理珠江原水，氧化沟分别装填三类四种填料。试验以高氨氮期间珠江原水为水源研究四段式接触氧化沟对氨氮、亚硝酸盐、COD和浊度的去除效果。试验期间氧化沟末段出水氨氮、亚硝酸盐、COD和浊度平均值分别为0．33mg／L、0．14mg／L、3．65mg／L、16．05NTU，相对于珠江原水的平均去除率分别为93．16％、44．09％、44．86％和64．47％。

| Abstract: | The removal efficiency of ammonia nitrogen, nitrite, CODMn and turbidity by four-section type contact oxidation ditch was studied with Zhujiang river water as the feed during high strength ammonia nitrogen. The test showed that, when ammonia nitrogen, nitrite, CODMn and turbidity in end-section effluent were 0.33 rag/L,0.14 rag/L,3.65 mg/L and 16.05NTU, the average removal rates were 93.16% ,44.09% ,44.86% and 64.47% respectively. The technological process had more idea treating effect, especially for ammonia nitrogen removal, it had very high removal rate. |
