我国城镇污泥处理与处置新型技术研究

Research on new technology of municipal sludge treatment and disposal

随着我国城市化进程的不断加快,城市污水的排放量也随之增加,由此产生的大量污泥容易对大气、水体、土壤造成二次污染,使生存环境进一步恶化,生态环境难以修复。在系统总结国内外已有成果的基础上,梳理国内外关于城市污泥处理与处置的新技术,分析污水处理厂污泥处理的关键技术和难点,引进新型污泥处理处置方法,以期为流域水环境综合治理提供理论保障和技术支撑。

In recent years, with the acceleration of urbanization, the discharge of urban sewage has also increased, resulting in a large amount of sludge, which is likely to cause secondary pollution to the atmosphere, water and soil, and further deteriorate the environment in which people live and make the environment hard to repair. On the basis of systematically summarizing the existing achievements at home and abroad, this paper sorts out new technologies at home and abroad for the treatment and disposal of municipal sludge and river sediments, analyzes the key technologies and difficulties of sludge treatment in sewage treatment plants, and introduces new sediment and sludge treatment and disposal methods in order to provide theoretical guarantee and technical support for the comprehensive management of water environment in the basin.
