摘要
通过向膜生物反应器(MBR)添加生物促生剂后形成生物促生剂膜生物反应器,分析生物促生剂对活性污泥性能以及对印染废水处理效果的影响,试验结果表明添加生物促生剂后,活性污泥结构紧密,颗粒增大,且微型动物的种类增多,同时COD和氨氮的处理效果分别提高了5%和8%左右,染料的去除率也提高了6%,适当延长水力停留时间或者泥龄可有效提高色度的去除效果。说明添加生物促生剂能较好的改善污泥性能,提高系统处理效果。
Through analyzing influence of adding biological preparation into membrane bioreactor （MBR） on activated sludge performance and efficiency of wastewater treatment, the results showed： after adding biological preparation, the structure of activated sludge was compact which had abundant in micro organisms, its particle size was larger and the removal efficiency of COD and NH3-N was increased evidently which could reach 5 % and 8 % respectively. Dyestuff removal efficiency also improved 6 % that could be increased by prolonging HRT or SRT. All the phenomena showed that adding biologieal preparation into MBR could improve sludge performance and increase treatment efficiency.
