摘　　要：通过向传统SBR反应器中投加适当的强磁性粉末(Fe_(3)O_(4))以强化活性污泥沉淀性能、降低污泥负荷,实现了反应器内污水处理效果的增强。实验结果表明:投加的磁粉粒度为30 nm,磁粉浓度为2000 mg/L时,整体优于传统SBR法,期间COD、NH_(4)^(+)-N、TP的平均去除率分别为98.51%、95.27%、83.90%;磁粉加入后,提高了污泥浓度,即使SV_(30)达到70%以上,MLSS达到9500 mg/L左右时,在处理高浓度的食堂淘米污水条件下,反应器也可以正常运行;实验期间3种工况均对COD、NH_(4)^(+)-N去除效果较好,对TP、TN去除率也能达到70%左右。To enhance the precipitation performance of activated sludge and reduce the sludge load,the effect of sewage treatment in the traditional SBR reactor was enhanced by adding appropriate strong magnetic powder(Fe_(3)O_(4)).The results showed that it was superior to the traditional SBR system when the particle size of the magnetic powder was 30 nm and the magnetic powder concentration was 2000 mg/L.The average removal rates of COD,NH_(4)^(+)-N and TP during the period were 98.51%,95.27%and 83.90%,respectively.The reactor operated normally in the conditions of high-concentration canteen rice-washing sewage with improving sludge concentration,70%of SV_(30) and the 9500 mg/L of MLSS,in which the magnetic powder was added.The COD and NH_(4)^(+)-N were removed efficiently in the three working conditions and the removal rates of TP and TN could reach about 70%.
