南宁市正在进行水环境建设,并取得了初步成果,也遇到了一些问题。介绍了南宁市水环境规划总体结构及水环境建设情况,对水环境建设及运营过程中遇到的水质问题进行了分析和总结。针对存在的问题,对水环境建设过程中河湖设置形式、河道截污系统的设计与建设、初期雨水的处理等进行研究。根据南宁市水环境现况,南宁市水环境建设河湖设置宜采用河湖分立形式,河道截污应增加截流倍数,并相应地配套提升污水收集、处理系统能力,应采取措施减少或避免初期雨水对水环境水质的影响。
Nanning City, ongoing water environment construction, and achieved initial results, but also encountered some problems. The overall structure of water environment planning and the construction of water environment in Nanning are introduced. The water quality problems encountered in the construction and operation of water environment are analyzed and summarized. In view of the existing problems, this paper studies the setting forms of rivers and lakes, the design and construction of river interception system and the treatment of initial rainwater in the process of water environment construction. According to the current situation of water environment in Nanning, Nanning City, the water environment should be set up rivers and lakes to set up a separate form of rivers and lakes should be intercepted cutoff multiples, and correspondingly supporting the sewage collection, processing system capacity, measures should be taken to reduce or avoid the initial Influence of rainwater on water environment and water quality.
