北大港水库分库前后水质安全数值模拟

Research on Water Quality Safety of Beidagang Reservoir Before and After It's Divided

为探索北大港水库分库的可行性,假定北大港水库在维持水库现状、分库不挖深及分库挖深1 m三种工况条件下均调蓄3亿m3"引黄水"时,运用零维水质模型对其水量水质的变化进行模拟,以此对比探究水库分库前后水质安全。结果表明:水库分库时较不分库时具有水质咸化风险低、不超标天数多及可供水量大等优点,即水库分库较不分库水质安全,同时水库分库时不挖深较挖深好。

Abstract： In order to explore the feasibility of Beidagang Reservoir when it~ divided, it was assumed that Beidagang Reservoir regulated 300 million m3 of the Yellow River water in three kinds of working conditions ： maintaining the reservoir status quo, the reservoir was not deepened when it was di- vided and the reservoir was deepened lm when it was divided. This paper used zero-dimensional water quality model to simulate its changes in water quantity and quality. The results show that the risk of water salinization is lower, the number of days of C1 - is not exceeding and available water is more when it＇s divided. So it＇s feasible when Beidagang Reservoir is divided and it~ better than that the reservoir isnl deepened when it＇s divided.
