摘要
通过中试试验,考察了不同滤料介质的生物滤池对于姚江微污染水源水的处理效果。结果表明,双层生物滤料滤池能够有效地去除有机物、氨氮等污染物质,可以延长滤池反冲洗周期,并能在短时间内恢复到正常处理能力,适合于传统滤池的改造。采用颗粒活性炭-石英砂滤料滤池的综合处理效果优于同类型的颗粒活性炭-沸石滤料滤池,通过加入少量臭氧(0.8～1.0mg/L)可以提高生物滤池的去除效果。
Through pilot test, theeffect ofbio-filter with different filter media on the treatment of Yaojiang slightly polluted water was enquired. The resuit showed that dual media biofilter could remove turbidity, organic matters and NH3-N, and the filtration period was longer. The removal rates could grow up to the normal level soon. As a result the biofilter is suitable for the modification of the traditional filter. The GAC-sand media was superior to GAC-zeolite media and it could enhance the removal rate by the addition of ozone（0.8-1.0mg/L）.
