高效厌氧反应器处理高浓度生活污水_张建强高效厌氧反应器处理高浓度生活污水＊张建强(华盛国际建筑设计工程咨询有限公司合肥230001)摘要研究了采用厌氧膨胀颗粒污泥床反应器(EGSB)处理高浓度生活污水的可行性。试验结果表明,采用EGSB处理生活污水,出水水质较好。COD去除率达到80%-93%,出水COD值在100mg/L以下;最佳水力停留时间为1h;SS的去除率在92%-95%之间;出水氨氮值高于进水值,出水总磷值略低于进水值,氮磷去除效果较差。试验说明采用EGSB反应器处理高浓度生活污水是可行的。关键词EGSB反应器高浓度生活污水可行性HighConcentrationofMunicipalWastewaterTreatmentWithEffectiveAnaerobicReactorZHANGJian-qiang(WashInternationalArchitectural&EngineeringConsultingCo.,Ltd.Hefei230001)AbstractThefeasibilityofhighconcentrationofmunicipalwastewatertreatmentwitheffectiveanaerobicreactorEGSBisresearched.Theexperimentindicatesthattheeffluentqualityispreferable.TheremovalrateofCODcanreach80%-93%andtheeffluentCODislessthan100mg/L;theoptimalhydraulicretentiontimeis1hour;theremovalrateofSSisbetween92%and95%;theammoniavalueineffluentishigherthanthatininfluent,butphosphorusineffluentisalittlelowerthanthatininfluent,andtheremovalefficiencyofnitrogenandphosphorusisratherbad.TheexperimentshowsthatitisfeasibiletoadoptEGSBreactorintreatinghighconcentrat
