高浓度活性污泥法的后续试验研究_周克钊

高浓度活性污泥法的后续试验研究周克钊(中国市政工程西南设计研究院,四川成都610081)　　摘　要:　高浓度活性污泥法采用兼氧、好氧组合流程,最显著的特点是全流程活性污泥浓度高和好氧前段的溶解氧浓度低。显著的同步硝化反硝化使该工艺可以在相当短的水力停留时间和较低的总回流比条件下,达到极高的总氮去除效果,同时相当有效地去除总磷和其他污染物。在原中试结束一年后又开展了后续试验,不仅重现了当时高浓度活性污泥法的优异处理效果,而且其脱氮除磷效果进一步提高。　　关键词:　城市污水;　高浓度活性污泥法;　后续试验中图分类号:X703　　文献标识码:C　　文章编号:1000-4602(2010)15-0082-04SubsequentTestofHigh-concentrationActivatedSludgeProcessZHOUKe-zhao(SouthwestMunicipalEngineeringDesignandResearchInstituteofChina,Chengdu610081,China)　　Abstract:　High-concentrationactivatedsludgeprocessintegratesfacultativeanaerobicandaerobicstages,anditischaracterizedbyhighMLSSinwholeprocessandlowDOinaerobicforepart.ThisprocesscanexcellentlyremoveTNatshortHRTandsmallTRRbysignificantSND,andefficientlyre-moveTPandotherpollutants.Thesubsequenttestafteroneyearfromtheoriginalpilottestshowthatthisprocessstillhastheexcellenttreatmentefficiency,andthenitrogenandphosphorusremovalefficiencyisfurtherimproved.　　Keywords:　municipalsewage;　high-concentrationactivatedsludgeprocess;　subsequenttest　　深
