不同功能采煤沉陷积水区单因子指数水质评价

Water Quality Evaluation of Single Factor Index for Water Subsidence Area with Different Functions in Coal Mining

以淮南潘集封闭式采煤沉陷积水区为研究对象,进行2015年11月到2016年6月采样监测,设定渔业养殖和农业灌溉两种评价情景,采用单因子指数法对该地区水质现状进行不同功能的水质评价。结果表明:基于渔业养殖功能,该地区水质总体上受到了中轻度污染,特征污染指标为COD_(Cr)、TN和TP;基于农业灌溉功能,该地区冬季水质较好,春夏季水质受到轻度污染,特征污染物指标为COD_(Cr);建议管理部门应当综合考虑当地的水体利用现状和经济发展规划,并制定有效的管理和保护措施。

Taking Huainan Panji Closed Coal Mining Subsidence Water Area as research object,sampling monitoring was conducted from November 2015 to June 2016.Two evaluation scenarios of fishery farming and agricultural irrigation were set up,using single factor index water quality status of different functions of water quality evaluation.The results showed that the water quality of the area was generally mildly polluted and the characteristic pollution indicators were COD Cr,TN and TP.Based on the function of agricultural irrigation,the water quality in winter in this area was good and the water quality in spring and summer was slightly polluted.The indicator of characteristic pollutants was COD Cr.It was suggested that the management department should consider the current situation of water utilization and economic development plan of the area comprehensively and formulate effective management and protection measures.
