摘要
临淄区是著名的化工城,为区域经济发展带来了巨大的促进作用,然而在生产过程中产生的环境问题也十分突出。针对临淄区地下水分布广泛,地貌、水文地质条件复杂,化工企业众多,地下水污染风险控制因素复杂,采用地下水地层防污性能叠加污染源强度建立模型,划分了临淄区地下水污染风险高、较高、中、低风险区域。其中,堠皋地区污染风险高,地下水样品分析结果表明此区域内地下水苯系物污染严重,证实了污染风险划分的有效性及客观性。建议对高风险地区采取更为严格的防控措施,主要包括完善监管制度、联合采用多种措施阻断污染途径、查明污染来源及包气带、含水层联合处置的方式改善地下水质量。
Linzi District is a famous chemical city,which has played a great role in promoting regional economic development.However,the environmental problems in the production process are also very prominent.In the light of the characteristics of Linzi area,such as wide distribution of groundwater,complex geomorphic and hydrogeological conditions,and so much chemical enterprises,the risk control factors of groundwater pollution are complex.Through coupling formation antifouling performance with groundwater contaminant sources,the integrated multi-index models were developed to divide the risk of groundwater in Linzi.Among them,the pollution risk in Hougao area is high.The analysis results of groundwater samples show that the groundwater in this area is seriously polluted by benzene,which confirms the effectiveness and objectivity of pollution risk classification.And the high-risk areas should take more strict prevention and control measures,such as improving the monitoring system,jointly adopting a variety of measures to block pollution routes,identifying pollution sources and joint disposal of unsaturated zone and aquifers to improve the quality of groundwater.
