盐城市滨海县城区区域枯水期水环境质量调查分析

Investigation and Analysis of Water Environment Quality in Binhai County Urban Area of Jiangsu Province in Dry Season

笔者采用单因子评价法分析与评价枯水期滨海县城区及开发区工业园区范围水质污染特征和现状。调查范围面积约50.8平方公里,包括主要河道、城市内河、开发区工业园区内部河道及周边支流。结果为调查区域内地表水水质呈重度污染状况,主要原因分析为时值枯水期,水体长期滞留,在无充足水源补充的情况下,由于环境基础设施建设滞后,区域内生活污染物和工业污染物不断入河导致地表水污染日益加重。该评价结果能为滨海县水环境保护和科学治理提供依据。

In the dry season,the author conducted an investigation on the water environment quality in the urban area of Binhai County and the industrial park of the development zone.The investigation area is about 50.8 square kilometers,including the water quality of main rivers,urban rivers,internal rivers of the industrial park of the development zone and surrounding tributaries.Results In order to investigate the serious pollution of the surface water quality in the area,the main reason is analyzed as follows:during the dry season,the water body has been detained for a long time.In the absence of adequate water supply,due to the lagging construction of environmental infrastructure,the domestic pollutants and industrial pollutants in the area continue to enter the river,causing the surface water pollution to become increasingly serious.
