Sludge Disposal Scheme Of Ni Buwan Sewage Treatment Plant

Urbanization development and sewage industry development have brought about a soaring increment of sewage sludge, how to dispose the ever-increasing sewage sludge and eliminate their hazard has become a serious problem with which people are currently confronted. The final objective of sewage sludge is to meet the requirements of decrement, stabilization, detoxification, and the main tendency is energy and resources recycle.At present the incineration technology is thought as one of the most practicable technology in the field of sewage sludge treatment in the world. In the most of countries, such as European countries, America, Japan, etc., this technology has been very popular and operated successfully step by step. Its obvious advantages are fast disposal speed, decreasing components efficiently and recycle energy as well. And in the recent years most of countries make much more strict regulations on the time and space of disposing wastes, so incineration technology has been a main method of sewage sludge treatment. In China, the study on wastes incineration is behind of developed countries, especially lacking of fundamental research on the field of sewage sludge incineration. Therefore, the technology of incineration becomes increasingly necessary. To conform to the new trend, incineration has become a promising disposal method.The details as follows:in this paper, the characteristics of the Ni Buwan Sewage Treatment Plant analyzed and introduction on the sludge treatment and disposal technique in recent years. On the basis of the information about sludge treatment and reusing introduction on the new development of sludge utilization. In combination with Present Condition of Ni Buwan Sewage Treatment Plant, we should take the incineration technology and supplement with the other ways. The trial for the use of Qingdao Ebara Renewable Resources Power Co., Ltd as the base reference to the characteristics of the Ni Buwan Sewage Treatment Plant sludge to design a sludge, incineration program, and the analysis of economic benefits, environmental benefits and social benefits.
