摘  要：
为探讨膜生物反应器(MBR)处理猪场污水的可行性和膜生物反应器的运行、操作条件,为膜生物反应器在处理猪场污水中的应用提供必要的基础参数,该文采用U型中空纤维膜和L式中空纤维膜生物反应器,对不同的化学需氧量(COD)及氨氮(NH+4-N)进水浓度、溶解氧水平(DO)、污泥龄(SRT)进行了4种工况试验研究。结果表明,MBR作为猪场污水处理好氧段是可行的,当进水COD平均浓度为1860mg/L,U型、L式膜平均去除率分别为84.10%,81.20%;NH+4-N进水平均浓度为511mg/L,U型、L式膜平均去除率分别为93.81%,93.61%。

摘  要：
To assess the feasibility of swine waste water treatment by using membrane bioreactor and provide the design and application parameters, experiments with U shape and L shape hollow fibre membrane were conducted under four operation conditions with different influent COD and ammonia nitrogen concentrations, different DO levels and SRTs in the reaction water. The results confirmed the feasibility of MBR as swine waste water aerobic treatment stage and showed that the third operation condition was the most effective. When the average influent COD concentration was 1860 mg/L, the removal rates of U shape and L shape membrane were 84.1%, 81.2%, respectively, the removal rates of NH+ 4-N were 93.81% in U shape membrane and 93.61% in L shape membrane respectively when the influent NH+ 4-N concentration was 511 mg/L on average.
