西南地区农村污水处理

Rural Sewage Treatment in Southwest China

摘要:

提高农村污水收集率和处理率是美丽乡村建设的重要内容。现状农村污水站设计及运维存在很多不足之处，普遍存在污水站设计规模偏大、运行不足、闲置突出等问题。以西南地区某县107座农村污水处理站为调查研究对象，针对现状污水站的运维数据调研，提出微型、小型、大型污水处理站分别采用循环氧气污水处理工艺、SCAS（改良SBR）、改良AAO工艺，通过运行效果分析探索适用于西南地区农村生活污水处理工艺以及长效管理机制。

Abstract:

Improving the collection and treatment rates of rural sewage is an important content of building a beautiful countryside. There are many shortcomings in the design， operation and maintenance of rural sewage stations， which are large design scale， insufficient operation， and prominent idleness of the sewage stations. Taking 107 rural sewage treatment stations in a county in the southwest region as the research objects， aiming at the operation and maintenance data of the present sewage stations， it is proposed that the circulating oxygen sewage treatment process， SCAS （modified SBR) and improved AAO process are used for the micro， small and large sewage treatment stations respectively. Through the analysis of operational effects， the treatment process and long-term management mechanism of rural domestic sewage suitable for the southwest China are explored.
