摘要
随着城市化进程的不断推进,随之而来的是不断增加的污水排放,由此也产生了大量污泥。目前,我国的污泥处理技术的处理效率较低,大量的毒害物质存在于污泥当中,没有及时妥善地处理,就产生二次污染的可能。污泥具有一定的潜在价值,将污泥再生利用是未来的发展方向。本文通过分析污泥处理处置的现实状况,阐述了污泥处理处置技术,并简要探讨了污泥各种处理、处置方法的优劣以及未来发展的方向。
With the continuous advancement of urbanization,it is accompanied by increasing sewage discharge,resulting in a large amount of sludge.At present,the treatment efficiency of sludge treatment technology in China is low,and a large amount of toxic substances are present in the sludge.If it is not properly treated in time,secondary pollution may occur.Sludge has certain potential value,and the renewable utilization of sludge is the future development direction.This paper analyzes the actual situation of sludge treatment and disposal,expounds the sludge treatment and disposal technology,and briefly discusses the advantages and disadvantages of various treatment and disposal methods of sludge and the direction of future development.
