- 摘要：根据2018年绥化市第一水源地13口监测井水质检测结果分析地下水污染特征，并对地下水质进行综合评价.结果表明：绥化市第一水源地取水井主要超标因子为铁、锰、氨氮，第一水源地补给区内其他取水井监测指标中铁、锰、氨氮、溶解性总固体和总硬度超标.硫酸盐、氯化物、溶解性总固体、总硬度、氟化物和磷酸盐浓度高值区均出现在垃圾填埋场，高锰酸盐指数和氨氮的高值区出现在太平岗村屯地下水井，硝酸盐高值区出现在兴发村屯地下水井.地下水污染评价结果显示污染指标主要为溶解性总固体和氨氮，分别为中污染和极重污染，主要集中有B5、B7、B8、B9、E和X1.溶解性总固体、硫酸盐、氯化物和总硬度空间分布呈相似趋势，高值区均出现在E、X1、B7、B8和B9.氨氮高值区出现在X1，这可能与该处为垃圾填埋场有关.高锰酸盐指数高值区出现在E，硝酸盐氮高值区出现在B8，砷浓度的空间分布没有变化.
- Abstract：According to the water quality test results of 13 monitoring wells in the first water source of Suihua City in 2018, the groundwater pollution characteristics were analyzed, and the groundwater quality was comprehensively evaluated. The results show:The main over-standard factors for water wells in the first water source area of Suihua City are iron, manganese and ammonia nitrogen. The monitoring indexes of other water intake wells in the first water source recharge area are iron, manganese, ammonia nitrogen, total dissolved solids and total hardness exceeding the standard. Sulphate, chloride, total dissolved solids, total hardness, fluoride and phosphate concentration areas are all present in landfills. Permanganate index and high value areas of ammonia nitrogen appear in Taipinggang Village. In the high-value area of nitrate, there is a groundwater well in Xingfa Village. The results of groundwater pollution assessment showed that the pollution indicators were mainly dissolved total solids and ammonia nitrogen, which were medium pollution and extremely heavy pollution, mainly concentrated in B5, B7, B8, B9, E and X1. The spatial distribution of dissolved total solids, sulfate, chloride and total hardness showed a similar trend, and the high value areas appeared in E, X1, B7, B8 and B9. The high ammonia nitrogen area appears in X1, which may be related to the landfill. The high permanganate index area appears in E, the nitrate nitrogen high value area appears in B8, and the spatial distribution of arsenic concentration does not change.
