摘　　要：采用厌氧-缺氧-MBR工艺处理纺丝废水,并考察该工艺的处理效果.结果表明,纺丝废水进水CODCr质量浓度在6730mg/L左右,出水CODCr最低平均质量浓度为466mg/L,CODCr去除率达到90%.实验同时表明,按照实验中设定的控制条件系统能够稳定运行.但由于废水含有大量氮元素以及反应器内菌群的抑制作用,实验产水氨氮浓度较高,平均质量浓度为294mg/L.The process of hydrolytic acidification-anoxic-aerobic MBR is used on treatment of spinning wastewater, as well as the treatment effect of this process is studied. The results show that the influent CODcr is about 6 730mg/L, and the effluent CODcr is about 466 mg/L in average. The removal rate of CODcr reaches 90%, which means the process can remove the organic pollutants efficiently. The experiments also show that the system can run steadily under the control conditions set in experiment. But the ammonia concentration of effluent is with a high value of 294 mg/L in average, because of the high concentration of nitrogen element and the inhibitory effect of microorganism in reactor.
