小城镇污水一体化生物处理工艺技术研究进展

摘要

目前全国存在数量巨大的小城镇,未经处理直接排放大量污水,超过了当地环境所能承受的自净范围,严重影响居民的日常生活环境.由于小城镇排水收集管网系统很不完善,应用具有投资小、处理效率高、管理方便、设备运行灵活的一体化污水处理技术处理小城镇污水受到青睐.将基于小城镇污水的排放特征和处理要求,分析阐述国内外应用较广的一体化污水处理工艺,以期为小城镇污水一体化工艺的选择提供参考.%There are a huge number of small towns in our country at present,wastewater of most of the small towns are directly discharged which has exceeded the local environmental carrying capacity,seriously influenced the daily life of the residents.Due to the drainage collection pipe network system of small town is not perfect,the application of integrated sewage treatment technology with small investment,high efficiency,convenient management and flexible operation is favored in small towns.This paper base on the discharge characteristics and treatment requirements of sewage in small towns,analyzed the technologies of integrated wastewater treatment widely used at home and abroad,in order to provide reference for the selection of integration process of the small town sewage.
