摘　　要：将自主研发的主动错流式膜分离设备用于校园生活污水的处理,膜设备安装在厌氧膨胀颗粒床反应器(EGSB)上代替原有的三相分离器,以程序控制旋转操作实现主动式错流过滤。结果表明,出水COD浓度<15 mg/L,去除率达到了89.9%;除浊效果好,除浊率达到了82.58%;系统对TP和NH_4^+-N基本没有去除作用,需要合适的后续处理手段。主动错流膜设备产生的水力剪切力能有效防止滤饼层产生,表现出良好的抗污染能力。系统运行过程中膜通量基本稳定,跨膜压差增长缓慢。An active cross-flow anaerobic membrane bioreactor device was used to treat campus sewage. The membrane device was installed on EGSB to replace the three-phase separator, and the active cross-flow filtration was implemented by programmed rotation operation. The results showed that the effluent COD was below 15 mg/L with a removal rate of 89.9%. The removal rate of turbidity was 82.58%. However, TP and NH4＋ - N were not removed, which indicated necessity of subsequent processing. The cake layer formation was prevented effectively due to the large fluid shear force on the membrane surface. The rate of membrane fouling was significantly reduced, and the membrane showed excellent pollution resistance. During the experiment, the membrane flux remained stable and the operating pressure of the membrane was slowly increased.
