塔山水库入库河流水质污染状况调查与评价研究

Investigation and Evaluation of Influent Water Quality in Tashan Reservoir

对连云港市赣榆区唯一的集中式地表水饮用水源地塔山水库的青口河、旦头河、汪子头河等三条入库河流布设监测点,开展连续12个月的水质状况现场调查和实验室分析。研究项目选择氨氮、总氮、总磷、叶绿素、透明度、p H、溶解氧、电导率、高锰酸盐指数、悬浮物共10个指标,重点分析氨氮、总氮、总磷、高锰酸盐指数4项指标。研究认为调查时期塔山水库水质处于中度及以上富营养化水平,库区主要污染来自入库河水。

This study take water samples from Qingkou River, Dan River and Wangzitou River, three influent tributaries of Tashan Reservoir, the only centralized surface drinking water source area of Ganyu District of Lianyungang City. Three warehousing rivers the layout of monitoring points, to carry out the analysis for 12 consecutive months of water quality condition of field investigation and laboratory. A total of 10 indicators were monitored, including ammonia nitrogen, total nitrogen, total phosphorus, chlorophyll pH, transparency, conductivity, dissolved oxygen, permanganate index, suspended matter, research project selection,4 indexes of key analysis of ammonia nitrogen, total phosphorus, total nitrogen, permanganate index. Studies show that survey period in Tashan Reservoir water in the moderate and above level of eutrophication, pollution mainly comes from the influents.
