Abstract

Abstract:

Since 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.

Key words: excess sludge, sludge reduction, chemical uncoupler, reduction effect, sludge character
