摘　　要：针对日益严重的污泥问题,从污泥减量效果、出水水质及污泥性质等方面归纳和总结了以"源头控制"为目标的化学解偶联剂污泥减量技术的研究现状,阐述了化学解偶联剂污泥减量技术的机理及化学解偶联剂的种类和特点,详细讨论了化学解偶联剂的污泥减量效果及其对COD、N、P去除和污泥沉降性、活性、絮体结构与微生物群落结构等的影响及影响因素,并指出了这种污泥减量技术目前存在的问题和今后的发展方向。Si nce the sludge problem is getting more and more serious ,the research statue of sludge reduction tech-nology,which is an important technology aiming at “source control”as its target,by using chemical uncoupler,has been concluded and summarized in terms of sludge reduction effect,effluent water quality,and sludge characteristics. The mechanisms and types and features of chemical uncouplers are expounded. The chemical sludge reduction effect of the chemical uncoupler,and its influences and influencing factors on the removal of COD,N and P,settleability, activity,floc structure,and microorganisms community structure are discussed in detail. The existing problems and future developing direction of the sludge reduction technology are put forward.
