谢桥采煤塌陷区水域水质特征及相关性研究
|
摘要
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.
This paper selects Xieqiao subsidence area as the research object,based on the physical indexes of water area in collapse,which includes temperature,water depth,transparency,suspended matter. Conventional chemical indicators includes total hardness,p H,total nitrogen,total phosphorus,TOC,COD,chlorophyll and other heavy metals,including Cu,Zn,Cd,and Pb other indicators. The results of these indicators in subsidence area were analyzed by SPSS18. 0 software to analysis the correlation of each index. Finally,the results show that in addition to suspended solids,the transparency between sampling points fluctuation changes large,water depth and temperature of each sampling point changes little from the point of view of physical properties. From the point of view of chemical indicators,the indicators are less than the national surface water of four kinds of standards; From the heavy metal indicators,Cd,Cr in northwest subsidence area exceeds the national water standard V,Cd,Cr and Pb in southeast of subsidence area exceeds the national water standard V. Through the analysis of the indicators,the water quality of the water area in the collapse area is evaluated,which provides a scientific basis for strengthening the management of pollution and monitoring the water level and water quality.
