山地丘陵及平原河网区农村生活污水处理模式

Treatment Countermeasures of Rural Domestic Wastewater in Hilly and Plain River Network Region

不同地区的农村水污染程度和特点不同,因而选择适宜的污水处理模式至关重要。根据山地丘陵区及平原河网区的地形特点和农村生活污水的排放特征,结合台州市农村污水处理现状,推荐山地丘陵区采用厌氧池—垂直流人工湿地、厌氧池—跌水充氧接触氧化—潜流人工湿地、单户式厌氧一体化处理器—分户式湿地等生活污水处理模式,平原河网区采用生态塘、地埋式微动力氧化沟技术、净化池等生活污水处理模式,并为台州市山地丘陵区下园村和平原河网区五联村设计了适宜的污水处理模式。

The extent and characteristics of the rural water pollution are different in different areas. So, selection of suitable treatment is very important. According to the topographical features of the hilly area and plain river network area and rural sewage emission characteristics, combined with the Taizhou rural sewage treatment situation, it is recommended to use the anaerobic pond-vertical flow constructed wetland, anaerobic pond-waterfall aerated contact oxidation-underflow constructed wetland, anaerobic single-family integrated processor-the household type of wetland in hilly area. In plain river network area, it is recommended to use the ecological pond, the buried micro-power oxidation ditch technology and purification pond technology. This paper designs a suitable wastewater treatment mode for Xiayuan Village in hilly area and Wulian Village in plain river network area in Taizhou City.
