摘　　要：针对传统的液氯消毒方式会导致输配水管网中的余氯浓度较高、时空波动较大等问题,提出了管网的二次加氯,并分别建立了二次加氯优化选址的数学模型和描述消毒剂投加量问题的离散时间的优化模型,同时采用0-1规划求解加氯点的位置及其相应的加氯量。结果表明,二次加氯会降低管网水中的余氯浓度及其时空波动,比传统的加氯方式具有更高的水质安全性,同时节省加氯量,获得较好的经济效益。Because the traditional chlorination may lead to high residual chlorine concentration and large temporal and spatial fluctuation in water distribution system, booster chlorination was proposed. The mathematical model of booster chlorination location and the optimization model of discrete time which describes the disinfectant dosage were established, and 0-1 integer program was used to solve the location of chlorination point and chlorine dosage. The study ease shows that booster chlorination would reduce the residual chlorine concentration and its temporal and spatial fluctuation, and it has higher water quality safety than the conventional method, saves chlorine dosage and gets better economic benefit.
