适宜我国农村生活排水处理技术模式研究

随着农村供水的快速发展,生活排水处理问题日益突出,迫切需要开展生活排水处理工程建设。通过承担相关标准编制及标准化关键技术研究,结合工程实践和现场调研,提出了适合农村生活排水特点的物理、生物、生态处理技术共13项,组合形成联村或单村集中式生活排水处理技术模式4种(生物膜法、活性污泥法、生物生态组合、生态组合处理技术模式)、联户或单户分散式生活排水处理技术模式3种(生态、生态组合、一体化处理技术模式),为各地进行农村生活排水处理技术和模式选择、工程规划设计提供参考。

Research on subsistence drainage treatment methods suitable for rural of China

With the rapid development of rural water supply, the subsistence drainage treatment is becoming so increasingly prominent that it is very urgent to carry out related project construction in rural areas. By working out the related standards and carrying out the research on standardization of key technologies, combined with engineering practice and in-site investigation, the author put forward thirteen items of technology and seven sorts of technical mode suitable for rural sewage treatment. The thirteen technologies included physical, biological and ecological treatment technique. Furthermore, the seven technical modes enclosed four kinds of centralized sewage treatment technology suitable for united villages or single village and three kinds of decentralized sewage treatment technology for joint or single family. All of mentioned above are aimed at providing references for the sewage treatment technology and mode selection, engineering planning and design.
