随着我国人口的增长和城市化进程的加快,工业废水和生活废水产生的下水道污泥已经成为主要的污染源之一,威胁着环境和人民健康。对下水道污泥的处理和利用一直是我国市政工作中的一个重点和难点,如何实现污泥处理的“减量化、无害化、稳定化、资源化”也是该领域研究的热点。本文概述了当前国内污泥处理的现状,通过分析当前比较成熟的污泥处理方法,展望了污泥处理及工艺研究的发展前景。
Sewage sludge from industrial wastewater and domestic wastewater has become one of the major sources of pollution as the population of our country grows and urbanization accelerates, threatening the environment and people’s health. The treatment and utilization of sewer sludge has always been a key and difficult point in the municipal work in our country. How to reduce, detoxify, stabilize and recycle sludge has also become a hot topic in this field. The current status of domestic sludge treatment is summarized. By analyzing the current more mature sludge treatment methods, the development prospects of sludge treatment and technology research are prospected.
