摘　　要：为了解决水环境问题,传统的污水处理方法将水污染问题转化为固废处置的问题,形成了巨大的经济、环境和社会压力.课题组依据自有的发明专利,在试验室自制了双曝气好氧双污泥回流双泥层过滤反应器,利用反应器各阶段产生的优势污泥混杂成复合污泥对自制面粉水进行试验研究,试验室测定了进出水COD_(Cr)、NH_3-N、各曝气区的污泥浓度.在COD_(Cr)容积负荷达到4~5kg/(m^3·d)时,COD_(Cr)去除率达到98%、氨氮去除率达到99%的条件下,实现了污泥减量90%以上.试验证明,反应器各区复合混杂的污泥的相互作用,使反应器在除碳脱氮的同时具有很强的污泥减量的能力.The amount of residual sludge of traditional wastewater biological disposal technology grows so big that a solid waste disposal problem becomes great in economic, environmental and social pressure. The paper designs a reactor with dual aeration and dual return and dual sludge filter partitions. Using different phases＇ composite sludge of the reactor, it performs an experiment with artificial feeding flour water. Under the condition of the CODCr volume loading 4-5 kg/（m^3· d ） , the experiment shows that CODCr removal rate could be 98% and ammonia nitrogen removal rate could reach 99%,and thus sludge reduction realizes over 90%. It is proved that microbe interaction of the mixed zone sludge in the reactor can remove carbon and nitrogen, and has the ability of sludge reduction.
