本文选取谢桥塌陷区为研究对象,通过对塌陷区水域中物理性指标:温度、水深、透明度、悬浮物等,常规化学性指标:总硬度、p H、总氮、总磷、TOC、COD、叶绿素等,重金属:Cu、Zn、Cd、Pb等指标,参照相关标准进行测定,得出结果后对塌陷区内这些指标进行分析,采用SPSS18.0软件对各指标进行相关性分析,得出:从物理性质来看,除悬浮物、透明度各采样点之间变化波动较大外,水深、温度各采样点变化不大;从化学性指标来看,各指标均小于国家地表水四类标准,从重金属指标来看,西北塌陷区Cd、Cr均超过国家Ⅴ类水标准,东南塌陷区Cd、Cr、Pb超过国家Ⅴ类水标准.通过对各指标的分析,对塌陷区水域水质进行了系统的评价,为加强污染管理,做好水位、水质的监测工作提供了科学依据.
In this paper, Xieqiao Subsidence Area is selected as the research object. The physical indexes such as temperature, water depth, transparency and suspended solids in the waters of the subsidence area are selected. The general chemical indexes, such as total hardness, p H, total nitrogen, total phosphorus, TOC, COD , Chlorophyll and other heavy metals: Cu, Zn, Cd, Pb and other indicators, with reference to the relevant standards for the determination of the collapse of the area after the results of these indicators were analyzed using SPSS18.0 software correlation analysis of the indicators obtained : From the physical point of view, in addition to suspended solids, changes in the transparency of the sampling points between the larger fluctuations, the water depth, temperature sampling point little change; from the chemical indicators, the indicators are less than the national standard of surface water four categories From the heavy metal index, the Cd and Cr in the subsidence area of Northwest China surpassed the national Grade V water standard, and the Cd, Cr and Pb in the subsidence area of the southeast exceeded the national Grade V water standard.Based on the analysis of each index, the water quality of subsidence area The evaluation of the system provides a scientific basis for strengthening pollution management and monitoring water level and water quality well.
