【摘要】 通过监测发展阶段的塌陷水域水体的理化指标:温度、透明度、BOD5、CODcr、总碱度、总硬度、常规离子等,分析淮南塌陷水域水质现状。监测结果表明:监测区域水体受到不同程度的污染,主要污染指标为BOD5和CODcr;水体中溶解氧丰富,总碱度、总硬度、Cl-、Ca2+和SO24-随时间推移有累积增长效应,这为塌陷水域的综合利用提供一定理论依据。更多还原

【Abstract】 This paper mainly analyzed the physicochemical indexes and got the situation of huai′nan subsidence water by inspecting during form period.The physicochemical indexes were inspected including Temperature,Diaphaneity,BOD5,CODcr,Total alkalinity,Total hardness,ions,etc.The result showed that the subsided water area were all subjected to different pollution,and the main pollution indexes of all subsided water areas are BOD5 and CODcr;Dissolved oxygen of water is rich,the total alkalinity、total hardness、Cl-、Ca2+ and SO2-4 were growing because of the cumulative action.For the effect of upstream,the quality of water at the north of Xie’qiao coal mine and Zhang′ji coal mine are better than the south of Xie′qiao coal mine.And discussing the relation of physicochemical indexes and seasons,so that provides a theoretical basis for utilization the resource of subsidence area.更多还原
