曝气生物滤池在净水厂预处理工艺中的设计应用

Design and Application of Biological Aerated Filter in Water Treatment Plant

针对宿迁市泗洪县水厂取水水源微污染的问题,采用曝气生物滤池(简称BAF)这种生物膜法污水处理工艺,对微污染水源进行预处理,其滤料选用凹凸棒复合材料。设计应用结果表明:BAF投资少、占地小,集曝气、截留悬浮物、降解有机物、高滤速等特点于一体,对氨氮和COD有良好的去除效果。应用结果对类似以微污染地表水为水源的净水厂具有一定的技术参考价值。

Aiming at the water plant in Sihong County of Suqian city water micro pollution, using biological aerated filter（BAF） of the biofilm wastewater treatment process, the pretreatment of micro polluted water, the material selection of attapulgite composite materials. The application results show that the BAF has the advantages of less investment, small occupation area, integration of aeration, interception of suspended matter,degradation of organic matter, high filtration rate, etc., and has a good removal effect on ammonia nitrogen and COD. The application results have certain reference value to the similar water treatment plant with micro polluted surface water.
