书书书水污染治理新型厌氧反应器启动运行试验*孙延格1王素兰1邢传宏1,2(1.郑州大学水利与环境学院环境与市政工程系,郑州450001;2.郑州大学膜科学与技术应用研究所,郑州450001)摘要:自行设计了一种新型厌氧反应器,并以模拟高浓度废水为基质,对其进行启动试验研究,考察在负压控制和间歇曝气条件下新型厌氧反应器的运行效果。结果表明:启动阶段COD去除率较高,平均去除率为70%,出水pH和SS稳定,反应器内无浮渣出现。同时,负压条件下反应器内所产沼气可优先分离,产气量及上升速度明显高于正压条件;另外,对反应器沉淀区污泥进行间歇曝气可加速污泥中微气泡的分离。关键词:厌氧;反应器;启动;模拟废水;负压;间歇曝气START-UPOFANINNOVATIVEANAEROBICREACTORSunYange1WangSulan1XingChuanhong1,2(1.DepartmentofEnvironmentandMunicipalEngineering,SchoolofWaterConservancyandEnvironmentEngineering,ZhengzhouUniversity,Zhengzhou450001,China;2.InstituteofMembraneScience&TechnicalApplication;ZhengzhouUniversity,Zhengzhou450001,China)Abstract:Aninnovativeanaerobicreactorwasdesignedandalaboratory-scaleexperimentwasconductedwithsimulatedwastewaterasinfluent,therunningeffectswereinvestigatedundertheconditionofnegativepressureandintermittentaeration.TheresultsshowedthattheaverageCODremovalrateofreactorcouldbe70%,theSSandpHofeffluentwerestable,andtherewasnoscuminthereactor.Inaddition,throughobservationitcouldbefoun
