淮北煤田临涣矿区地下水污染调查评价与治理研究

INVESTIGATION,EVALUATION AND TREATMENT OF GROUNDWATER POLLUTION IN THE LINHUAN MINING AREA OF THE HUAIBEI COALFIELD

以临涣矿区固体废物、矿区污水排污口等污染源周边浅层地下水为研究对象,对临涣矿区地下水污染现状进行调查及取样分析,并运用单项污染指数法和综合污染指数法评价浅层地下水污染情况。结果表明,污染源周边浅层地下水基本未受重金属元素污染,影响综合污染指数的主要指标是氨氮和亚硝酸盐。依据上述评价结果,提出临涣矿区地下水污染治理建议,为临涣矿区地下水污染治理提供科学依据。

Taking the shallow groundwater around the solid waste and sewage outlet of the Linhuan mining area as the research object,the current situation of groundwater pollution in the Linhuan mining area was investigated and sample analysis was made,and the single pollution index method and the comprehensive pollution index method were used to evaluate the shallow groundwater pollution.The results showed that the shallow groundwater around the pollution source was not polluted by heavy metals,and what mainly affect the comprehensive pollution index were ammonia nitrogen and nitrite.Based on the above evaluation results,suggestions on groundwater pollution control in the Linhuan mining area were put forward.
