组合物探方法在富Fe、Mn离子地区寻找优质水源勘查中的应用

黑龙江抚远地区位于三江平原东部，地下水资源丰富，就水量而言可以满足农业灌溉和生活用水需求.但受地质环境影响，该区第四系孔隙浅水中Fe、Mn离子含量偏高，区内非集中供水均采取该水层.长期饮用Fe、Mn离子超标水，已经严重的影响了居民生活质量.本次寻找优质水源勘查工作，采用成熟的高密度电阻率法与激电测深组合的方法，针对高铁、锰的地质环境，对第四系下伏新近系含水层进行探究，查明富水层分布特征.通过探采结合验证，说明设计组合物探方法合适，有效在团结村寻找到优质的水层，新层位水质分析结果符合饮用水标准，为重碳酸钙钠型极软弱碱性淡水.

APPUCATION OF COMBINED GEOPHYSICAL METHODS IN THE EXPLORATION FOR HIGH QUALITY GROUNDWATER IN Fe AND Mn IONS-ENRICHED AREAS

Fuyuan area of Heilongjiang Province in the east of the Sanjiang Plain is with abundant groundwater resources that meet the local needs of agricultural and domestic water in volume.However,due to the geological environment,the Fe and Mn ion contents is high in the Quaternary shallow water layer,which is extracted for nonconcentrated drinking water supply in the area.The over standard water has seriously affected the life quality of residents.In this survey for high-quality water source,the sophisticated methods of high-density resistivity and IP sounding are combined to explore the Neogene aquifer under the Quaternary cover.With exploration and mining,it is proved that the designed combination of geophysical methods is suitable and effective.The test shows that the found aquifer belongs to sodium bicarbonate type with low salinity and weak alkaline,qualified for drinking water standard.
