张集矿区花家湖水质氮磷特征分析及评价

Water Environment Assessment and Charactristic of Nitrogen and Phosphorus on Huajia Lakes in Zhangji Coal Mining Subsidence

选取花家湖上游(塌陷水域)和下游(自然湖泊)为2个研究站点,进行全年的水质调查分析,研究矿区塌陷对花家湖水质的影响。结果表明,花家湖上游塌陷区水域污染比自然湖泊严重,污染物质以氮为主要,水质主要为Ⅴ类水质标准,水体富营养化问题较为严重,以3月份污染最为严重。改善花家湖水质应减少上游矿区工业废水的排放,加强对下游渔业养殖的管理,合理利用和开发花家湖水资源。

The upstream of Huajia Lake(collapsed waters)and the downstream(natural lakes)were selected as two research sites, annual water quality has been surveyed and analysis to study the impact of mining subsidence on the water quality of Huajia Lake.The results show that the pollution in the upstream of Huajia Lake is more serious than the upstream, nitrogen is the main pollutant, the water quality is mainly the V water quality standard, and the water eutrophication problem is more serious.The improvement of the water quality of Huajia Lake should reduce the discharge of industrial wastewater in the upstream mining area, strengthen the management of downstream fishery culture, and rationally utilize and develop the water resources of Huajia Lake.
