丘陵地带农村生活污水收集处理研究--以眉山市仁寿县为例

Research on Collection and Treatment of Rural Domestic Sewage in Hilly Area--Case Study of Renshou County, Meishan City

为探索研究适合丘陵地带农村生活污水的收集处理模式,选取四川省眉山市仁寿县文宫镇的三个村组作为示范点,开展农村生活污水收集管网和集中处理终端建设研究。在对示范村组气候特征、地势地形、民房分布、污水排放及污水水质等进行充分调研分析的基础上,结合四川省农村生活污水排放标准,进行示范点污水收集处理系统的设计、施工、调试及试运行。示范工程建成试运行一年以来,入户支管无破损,主管网系统排水流畅,处理系统出水水质稳定达标,终端系统与周边环境相容性高,系统运行维护简便。本研究可为丘陵地带农村生活污水收集处理提供参考依据及技术模板。

To explore the suitable mode for rural domestic sewage treatment in hilly areas, three villages in Wengong Town, Renshou County, Meishan City were chosen as demonstration sites to carry out research on the construction of rural domestic sewage collection network and centralized treatment terminal. Design, construction, debugging and trial operation of demonstration projects were conducted on the basis of fully investigation and analysis of the climate characteristics, topography, residential distribution, sewage discharge and sewage quality of the demonstration village, combined with the discharge standard of rural domestic sewage of Sichuan Province. During the test run more than one year, the inlet branch pipe has not been damaged, the drainage system works smoothly, the effluent of treatment system meets the discharge standard stably, the terminal sewage collection and treatment system has high compatibility with the surrounding natural environment, and the system operation and maintenance is easy. The research can provide reference basis and technical template for rural domestic sewage treatment in hilly areas.
