【摘要】 为了缓解我国区域水资源短缺状况,降低水污染物质的排放量以及改善由于水污染带来的环境问题,必须以系统的观念,把区域内的给水、污水处理及中水系统作为一个有机的整体进行综合规划。区域水资源系统规划有利于保障人民的健康生活,保证和促进国民经济发展,保护生态环境,具有显著的经济、社会和环境等综合效益。深入分析了区域水资源系统的基本组成,综合考虑了区域内的给水、污水处理及中水系统; 分析了各个系统之间及其内部因素之间的协调统一性和相互制约性,找出系统重要因素及其内在联系; 分析了区域水资源系统的问题所在,最终确定区域水资源系统多目标优化模型的目标体系和约束条件。通过对搜集的大量给水、污水处理、中水系统建设费用及运行费用资料进行统计分析和系列设计,运用曲线拟合方法,建立水资源系统工程费用函数。而后从年经营费用、区域的总缺水量及排放到环境中的主要污染物含量入手,确定以区域的经济、社会、环境效益最大为目标函数,以满足各个子系统的水量、水质为约束条件,建立了完整的区域水资源系统多目标优化的数学模型。将遗传算法引入优化模型中进行求解。深入分析了遗传算法的特点、工作原理、运行步骤等,建立了针对于区域水资源系统多目标优化模型的遗传算法。以拟建区域为例,构建区域水资源系统多目标优化模型,运用遗传算法求解,获得了经济、社会及环境效益俱佳的优化结果,证明了区域水资源系统多目标优化模型的实用性与科学性
【Abstract】 It is essential that the water resource system programming which include regional water supply,polluted water disposal and reused water systerm must be put forward in order to alleviate the lack of water resources,lower the water pollution and slove water pollution problem.The systerm is propitious to safeguard people’s health,promote the economic and protect the environment.In short,it has benefits to economic,society and environment,etc. This paper thoroughly expounds the elements of regional water resource systerm,synthetically considers regional water supply polluted water disposal and reused water systerm,analyzes the coordination and the supervision of each system and elements.Then expounds the problem of regional water resources systerm and find out the relation and condition of these systerms and elements.Finally the multi-objective optimizing model’s objects and restrictions are ascertained. The cost model of regional water resource systerm is established by analyzing and projecting a plenty of datum about each part and using curve fitting compaction method.Then starting with the operation cost per year,total water shortage quantity,main pollutant content exhausted in the environment,the multi-objective optimizing model of regional water resource system established, which object function is maximum objective of integrated benefit of society,economy and environment,the restriction of water quantity and water quality. Genetic Arithmetic is uesing in the optimal model,and it’s characteristic,principle and approach are analyzed thoroughly.The Genetic Arithmetic for solving multi-objective optimizing model of regional water resource systerm is set up. Taking one region as an example,a multi-objective optimizing model of regional water resource systerm is established.By using the Genetic Arithmetic for solving the systerm programming,the results and decision scheme with good economic,society and environment returns are accomplished.This proved that the multi-objective optimizing model of regional water resource systerm is practicable and scientific.
