摘要
尾水排放水位的选取是城镇污水处理厂高程布置需要考虑的主要因素之一,对污水处理厂的工程造价、运行成本等都有重要影响。但现行规范、教材对尾水排放水位的选取只有定性描述,缺乏明确的量化规定。通过对高、中、低3种尾水排放水位选取方案的能耗进行对比分析,认为3种方案的能耗相当。因此认为污水处理厂的高程布置设计可以不受尾水排放水位的限制,而重点考虑污水处理厂的土石方平衡、工程造价、防洪排涝等因素。
The selection of tailwater discharge level is one of the main factors for the elevation layout of the urban sewage treatment plant,which influence importantly the engineering cost and operation cost of the sewage plant.The current standards and textbooks only describe the selection qualitatively and are lack of clear quantitative provisions.The energy consumptions of three discharge water levels of high、medium and low are analyzed and compared to be equivalent.Therefore,that the elevation layout design of the sewage treatment plant can’t be restricted by tailwater discharge water level.The earthwork balance,project cost,flood control and drainage of the sewage plant should be considered especially.
