摘要
皂市水利枢纽工程的天然砂石加工系统位于渫水河左岸的漫滩地上 ,枯水期河水走右河槽。为了取到河水冲洗骨料 ,应用渗渠原理 ,在河漫滩下预埋集水管至左岸泵站的集水间。设两座沉渣池处理废水废渣。每座沉渣池的工作周期为 14d ,即进水 7d ,压实、脱水 3～ 4d ,挖砂、清洗 4～ 3d。从设计上较好地解决了废水废渣的处理。对供水工程和废渣处理工艺流程作了详细介绍。
Natural sand gravel aggregate processing system for Zaoshi hydroporject is located on the left bank floodland of Xieshui river which flows along the right channel in dry season. In order to take water from the river to clean aggregate, applying seepage trench method, water collecting pipes are preembedded under the floodland and connected with sump pool of the left bank pump station. 2 sediment pools are set up for the waste water and residual debris disposal. The working period of each sediment pool is 14 days, 7 days for water intaking, 3～4 days for compaction and dewatering, 4～3 days for sand excavation and cleaning. The problem of the waste water and residual debris disposal is well solved in the design.
