脉冲喷流复合厌氧污泥床技术及应用

介绍了脉冲喷流复合厌氧污泥床技术用于低浓度有机废水处理的实验室及中试效果,以及在农村生活污水处理项目中的应用,结果表明:以该技术为核心的生活污水生物处理系统,在HRT为6～10h,即有机物容积负荷为0.93～0.52kgCOD/m3.d时,COD去除率可稳定达到35%以上,氨氮和总磷去除率可达到17%～25%,具有优化处理系统、强化处理效果、降低后续好氧段能耗及占地面积的特点。

Technology and Application of Sludge Bed with Pulse,Cascade,Composite Anaerobe

The paper introduces the technology of sludge bed with pulse,cascade,composite anaerobe,which is used for the laboratory of the organic wastewater treatment with low concentration and the effect of reclaimed water,and introduces the application in the project of rural domestic sewage water treatment.The result shows that by taking the technology as the bio-treatment system of domestic sewage water,the removal rate of COD can reach at over 35%,the removal rate of ammonianitrogen and total phosphor can reach at 17%~25% when HRT is 6~10h,i.e.load of organic matter cubage is 0.52kgCOD/m3.d. It bears the characteristics in optimizing treatment system,intensifying treatment result,reducing energy consumption and land area.
