摘　　要：随着城市规模的不断扩大,对市政污泥处理处置的要求也在不断提升。截止到2017年底,我国已建成污水处理厂5 192座,且仍有许多尚在建设的污水处理厂,但仍难以充分满足各地对市政污泥处理处置的需求。依据住房和城乡建设部的数据,我国通过无害化处理的污泥约占所有污泥的56%,仍有近半数的污泥未能得到无害化处理,这些未处理的污泥会导致一系列的环境问题,如土壤盐碱化、土壤微生物生物群被破坏、土壤肥力下降等,甚至导致土地无法种植,周边地区无法居住等严重问题。因此研究污泥处理处置对于我国治理环境污染、及城市的可持续发展具有重要意义。本文将对近年来市政污泥处理处置技术的应用进行分析,为污泥治理提供新的思路和技术上的参考。With the continuous expansion of urban scale,the requirements of municipal sludge treatment and disposal are also constantly improving.By the end of 2017,China has built 5192 sewage treatment plants,and there are still many sewage treatment plants still under construction,but it is still difficult to fully meet the needs of the current political sludge treatment and disposal.According to the data of the Ministry of Housing and Urban-Rural Development,the sludge treated through harmless treatment accounts for about 56%of all the sludge,so nearly half of the sludge has not been treated harmlessly.Failure to treat harmless sludge can lead to a series of environmental problems,such as soil salinization,microbial biomass damage,soil fertility decline,these environmental problems can lead to the land unable to be planted,surrounding housing,etc.In recent years,due to the expansion of urban construction scale and the increasing demand for sludge treatment,the problem of sludge treatment and disposal is becoming increasingly apparent Therefore,the study of sludge treatment and disposal is of great social significance,which is of great significance for environmental pollution control and urban sustainable development in China.This paper now analyzes the application of municipal sludge treatment and disposal technology in recent years to provide new ideas and technologies for sludge treatment.
