Present Situation on Resources Utilization of Sewage Sludge and its Potential Problems in China

Abstract:

Sewage sludge treatment and disposal has become a hot issue of current environmental concern, not only its effect will cause secondary pollution to the environment, more importantly, a large quantity of sludge is produced and growth rapidly, acceptable urban area is limited. So its become an important issue need to be solved by us urgently. This article present the current domestic sewage sludge treatment and disposal methods respectively, elaborate the ways for utility, explain the practical advantages and disadvantages of each of these approaches and analyze the existing problems. At the same time, a number of resource utilization of new technologies was prospected.
