摘　　要：选用聚乙烯醇（PVA）、海藻酸钠（SA）和河沙作为包埋固定化载体材料,制备成固定化复合菌小球（MB）,用于处理养猪废水,并以水体中氨氮和COD去除率为指标考察了影响养猪废水净化的各种因素。研究结果表明,在外界气温1~8°C、固定化小球投加量20%、曝气量6~7 mg/L、pH7.0~8.4和间歇曝气时间比1∶1时,养猪废水经过10 d的处理,COD和氨氮去除率分别可达87.8%和64.8%。Piggery wastewater was treated by immobilized mixed microorganisms which were made of PVA,SA and river sand,and some factors that affected the degradation process of piggery wastewater were studied by comparing the ammonia nitrogen and COD removal rate.The results indicated that the removal rates of COD and ammonia nitrogen were 87.8% and 64.8% respectively in the following conditions：the atmospheric temperature 1~8 °C,the dosage of MB 20%,DO concentration 6~7 mg/L,pH 7.0~8.4,and the ratio of aeration time to non-aeration time 1∶1,after 10 days treatment of piggery wastewater.Therefore,the method using immobilized technology to treat piggery wastewater is feasible at low temperature.
