某内湖污染源分析及处置对策

Analysis of Pollution Sources and Treatment Measures in An Inner Lake

针对某内湖水质的现状进行了水质数据调研和分析,结果表明内湖处于中营养到轻度富营养状态;湖水Redfield比值大于16,已属于磷限制状态;内湖的主要污染源为污水处理厂尾水、初期雨水、钓鱼饵料等。针对湖水水质现状和主要污染源,建议对污水处理厂技术进行升级改造,同时考虑调水计划,改进截流措施等技术对策,从而实现内湖水质提升的目标。

Aimed at the current status of the inner lake, the water quality data investigation and analysis were carried out. The results indicate the trophic status of inner lake is in mesotrophic to light eutrophic. Due to the Redfield ratio of lake water greater than 16, the lake had been the phosphorus-limited status. The main pollution sources of lake were tail water from sewage treatment plant, first flush rainwater, fish bait. For the lake water quality status and the main pollution sources, upgrading and reforming the technology of sewage treatment plant, considering water-transferred plans, improving the closure measures should be proposed. Thus, to achieve the goal of upgrading the lake water quality.
