新农村给水排水工程低成本建设适宜技术研究

摘要

新农村给水排水工程建设过程中普遍存在村民各家自备地下水源，污水厂构筑物能耗高，污废水资源回收利用率低等高成本建设现象。为了降低新农村建设成本，课题组对给水排水工程低成本适宜技术进行了研究。结果表明给水工程低成本技术主要是变分散式供水为集中式供水，采用变频泵加气压罐组合供水方式。排水工程低成本技术则是采用低能耗的自然生态处理系统处理污水，注重污废水资源的回收利用以及进行低影响开发。%There exist some high cost constructing phenomena during Construction of Water Sup-ply and Drainage Proj ect in New Rural Area such as own underground water source of villagers, high energy consumption of Sewage Disposal Structure and low efficiency of waste water resource recovery and utilization.In order to reduce the cost of new rural construction,we carry out study on appropriate technology of low cost construction of water supply and drainage proj ect.Result shows that low cost technology of water supply proj ect is mainly about changing decentralized water supply to centralized water supply and using combined water supply mode of frequency conversion pump with air pressure tank.Low cost technology of drainage engineering includes u-sing natural ecological treatment system with low energy consumption and paying attention to the recovery and utilization of waste water resources and low impact development.
