摘要
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。
Water environment construction is being carried out in Nanning, and there are some problems though preliminary results were achieved. The planning and construction of water environment were introduced. Problems of water quality arisen in water environment construction and operation were analyzed and summarized. Connection or separation between river and lake, design and construction of river sewage interception system and treatment of initial rainwater were studied aiming at the existing problems. According to the current situation, river-lake separation, an increase in interception ratio of combined system, improvement in collection and treatment of sewage, low impact development were sug- gested in water environment construction in Nanning. Countermeasures should be taken to reduce or avoid the influence of initial rainwater on water quality.
