摘要
在调查研究了三峡库区重庆段小城镇污水处理现状的基础上，根据库区水质特征、水环境保护的特殊要求和库区地理环境与经济条件特点，对适用污水处理工艺和技术进行比选，认为利用地形高差，采用跌水曝气式生物滤塔＋氧化沟处理方法是适用于库区小城镇的污水处理工艺与技术。
Based on analysis for the current wastewater treatment status of the Three Gorges Reservoir Region in Chongqing, some applicable wastewater treatment processes and technologies were choose and compared in the paper according to the charac- teristics of sewage water and the special demands for water environmental protection of the reservoir basin and its geographic or e- conomic specialties. It was suggested that biological filtration tower with falling waters aeration using terrain elevation ＋ oxidation ditch was suited to small towns in the reservoir basin.
