Sewage Sludge Treatment Current Research & Development

Sewage sludge is the main pollutant oil in the process of development, production and processing generated. if reasonable disposition, it will seriously pollute the surrounding environment. Because of its composition is more complex, there are lot methods to deal with, by nature classified as: integrated physical, chemical, biological method or several methods. This paper describes the approach and progress of sewage sludge. By comparing various methods, that the actual processing sewage sludge in the process of a comprehensive sewage sludge treatment is a direction of future, around the sewage sludge to find according to their nature and characteristics of sewage sludge harmless or utilization of the best methods. In order to achieve resource, economic, environmental optimization.
