生物陶粒滤池预处理富营养化水库水源的净化效果与工艺参数 总被引:5,自引:0,他引:5
针对受污染的水库水源水进行中试规模的生物陶粒滤池预处理实验研究。结果表明:生物陶粒滤池能有效地净化受污染水源水水质,对CODMn、NH3-N、NO-2-N、浊度、藻类总数、锰、THMFP等的平均去除率范围分别为19.3%~35%、89%~96.5%、97.5%~99%、57.5%~69%、60.1%~84.3%、59%~84.6%、10.4%~24.8%。其适宜的工艺参数为:水力负荷(滤速)4~6m/h,气水比0.75∶1~1∶1;反冲洗周期3~7d。 相似文献

IntroductionThe membrane bioreactor system was firstused by Smith et al[1] to filter activated sludge inthe 1 960 s. Since then,membrane manufacturingtechniques have improved and the membranebioreactor for wastewater treatment has beendeveloped and improved[2 7] . The performance of amembrane bioreactordepends to a large parton themembrane characteristics[8,9] .Although differenttypes of membrane bioreactors have been studiedfor and even applied to a variety of waste watertreatment problems,t… 相似文献
