我国南方农村生活污水处理技术的研发现状

A research on sewage disposal technology in rural south China

针对农村生活污水直接排放已经成为影响我国农村水环境质量主要因素之一的现状,从适合我国农村的以村落或居民点为单位进行生活污水分散式处理的思维入手,介绍了我国现今主要的分散式生活污水处理技术的原理、特点、不足及其应用现状;继而综合比较了这些技术的技术经济指标,提出了适合我国农村的分散式生活污水处理技术的设计原则;最后提出发展有较高水力负荷,并具备小规模设备化特征和多种生物处理单元复合的创新技术是我国农村生活污水处理技术发展的主要方向。

Untreated rural sewage is becoming one of the main reasons for the deterioration of rural water environment at present. In regard to the decentralized wastewater treatment in rural China, current technologies are presented with focuses on theoretical principle, features, deficiencies and appli- cations. Then some technical indexes are compared and future development is discussed concerning decentralized sewage disposal technologies in rural areas Lastly the direction id pointed out that, future technologies to be developed possess the merits of high hydraulic load, flexible dimensions and mixed treatment units.
