Study Of Municipal Sewage Treatment And Disposal Method

Sludge is the byproduct of the municipal waste water treatment. The quantity of sludge is very large and the component of it is very complex. If sludge can't be well disposed, it will give rise to two times pollution. At the same time, sludge is resource also and how to utilize it is the global noticed problem.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 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 lags behind the developed countries, especially lacking of Fundamental research on the field of sewage sludge incineration. Therefore, the technology of incineration becomes increasingly necessary.The details as follows: in this paper, the characteristics Of the sludge from municipal waste water treatment in Hefei are analyzed and introduction on the sludge treatment and disposal technique in recent years is presented. On the basis of the information about sludge treatment and reusing introduction on the new development of sludge utilization is also presented. In combination with present Condition of Hefei, we should take the incineration technology and supplement with the other ways.Referenced to the characteristics of the sludge in Hefei, this paper purpose appropriate sludge incineration and transportation equipment according to the characteristics of the sludge for Hefei. This paper provides technical Support for Sludge effective disposal. Analyzed the process of sludge incineration, this paper proposed environmental impacts and methods of controlling environmental pollution duration running of the project.In addition, analyzed investments of sludge incineration technology and other operating costs of sludge treatment technology, this paper pointed out the advantages and disadvantages of the sludge incineration methods and provide reference for Sludge treatment and disposal of Hefei city.
