Abstract

with the continuous acceleration of urban and town construction, the output of urban and town sewage is also increasing. To a great extent, this promotes the technological development and capacity expansion of urban and town sewage treatment plants. In the process of sewage treatment, a lot of sludge is inevitable. However, many urban and town sewage treatment plants pay more attention to the treatment of sewage and ignore the treatment of sludge. In this way, the sludge without proper treatment can be disposed at will. In the long run, this will not only affect the surrounding environment, but also hinder the development of social economy. Therefore, the urban and town sewage treatment plant should pay enough attention to the application of surplus sludge treatment and disposal technology. In this paper, the main problems existing in the treatment and disposal technology of surplus sludge in urban and town sewage treatment plants, and the treatment and disposal technology of surplus sludge in urban and town sewage treatment plants are both explored and analyzed, hoping to contribute to the long-term development of urban and town sewage treatment plants.

Highlights

In recent years, with the rapid development of urban and town sewage treatment plants, the treatment of sewage is more and more in-depth
With the increasing attention paid by the state to the sludge problem, the development and introduction speed of sludge treatment and disposal technology has been accelerated obviously
The direct landfill method is often adopted in the treatment and disposal of sludge for urban and town sewage treatment plants

Summary

Introduction

With the rapid development of urban and town sewage treatment plants, the treatment of sewage is more and more in-depth. The main problems existing in the treatment and disposal technology of surplus sludge in urban and town sewage treatment plant at present According to the actual situation of urban and town sewage treatment plants in China at present, the methods of sludge treatment and disposal mainly include agricultural utilization, drying treatment and direct landfill. The direct landfill method is often adopted in the treatment and disposal of sludge for urban and town sewage treatment plants.
