固定化微生物-曝气生物滤池(IBAF)技术用于微污染水处理的实验研究

The Experimental Study on River Lightly Polluted Water Treatment by Electrochemical Immobilization Biological Aerated Filter(IBAF)

以温榆河微污染水为研究对象,采用人工草生物载体固定微生物,并在曝气生物滤池反应系统中对其进行处理。河流微污染水中N、P营养缺乏,有机物浓度较低,而且水质变化较大。在水力停留时间为10 h、8h、6.3 h、4.7 h时,此工艺对此河水的处理效果有较大的差异,说明水力停留时间的不同对污染物去除率的影响较大。

Through the object of study on the slightly polluted water of Wenyu River,The manpower grass biological carrier was used to immobilize microorganisms in aeration biological filter react system for treatment of river water,which was lack of N,P,contained low organic matter,and water quality changes bigger.When HRT were 10 h,8 h,6.3 h,4.7 h,there were many differences in treatment efficiency,it could explain that diversity of HRT had a greater affection for the degradation rate of pollutants.
