以养猪场废水为处理对象,在不排泥情况下就膜生物反应器(MBR)在处理废水过程中污染物的去除效果、污泥特性以及膜通量的衰减情况进行了研究.结果表明,MBR对养猪场废水中污染物的去除效果较好.在水力停留时间(HRT)为9.6-48.0 h,化学需氧量(COD)和NH_4~+-N容积负荷分别为0.2-2.9和0.05-2.10 kg·m~(-3)·d~(-1)的条件下,MBR对COD和NH+4-N的去除率分别为80.1%-93.6%和76.8%-99.7%;反应器中的污泥浓度随容积负荷的增加而升高,膜通量随运行时间的增加而减小.

A swine wastewater treatment test was developed to examine operation effect of membrane bioreator (MBR) in the condition of no sludge discharge. We have studied the removal effects of pollutants, sludge characteristics and membrane permeate flux decline. The results indicated that MBR had a better pollutant removal effect for swine wastewater, in which the removal rates for chemical oxygen demand (COD) and NH_4~+-N were 80. 1%-93. 6% and 76. 8%-99. 7% respectively, when hydraulic retention time (HRT), COD and volume load for NH+4-N were 9. 6-48. 0 h, 0. 2-2. 9 and 0. 05-2. 10 kg·m~(-3)·d~(-1), respectively. The sludge concentration in MBR increased gradually with increasing volume load for NH_4~+-N, whereas the membrane permeate flux declined gradually with time.
