| 摘 要： | 采用新型三相内循环反应器处理生活污水，原污水COD值在228．3—592．5mg／L之间，NH3-N值在29．24～48．72mg/L之间，SS值在150～400mg/L之间，pH值为6．8～7．2，通过控制污泥浓度、水力停留时间及曝气量，分析了反应器对COD、NH3-N和SS的去除情况。试验结果表明：在污泥浓度为4500mg/L、水力停留时间为2小时、曝气量为200L/h的条件下，COD去除率为90．65％左右；NH3-N去除率为87．46％左右；SS去除率为94．7％左右。该反应器具有高效、低耗和低成本的优点，为处理生活污水提供了薪的参考依据。

| Abstract: | Domestic wastewater was treated by using a new three - phase internal - loop reactor,whose values of COD ranged from 228.3 mg/L to 592.5 mg/L,values of NH_3 - N were in 29.24 mg/L to 48.72mg/L,values of SS were about 150 to 400 mg/L,and values of pH were about 6.8 to 7.2.By controlling the sludge concentration,hydraulic retention time and aeration volume,the removal rate of COD,NH_3 - N and SS were analyzed.The results of the experiment showed that the removal rate of COD was about 90.65%,the removal rate o... |
