摘要: 通过对三江平原建三江农场采取的21组浅层地下水水样分析，发现Ⅲ类水1组，Ⅳ类水11组，Ⅴ类水9组，13组样品有机污染物有检出，均未超标.总体来看，三江平原建三江农场水田区地下水污染较为严重，大多数为Ⅳ、Ⅴ类，不适合作为生活饮用水使用.铁、锰受原生地质环境的影响部分超标；挥发酚与铅超标的原因尚待查明；有机氯农药类均没有检出，说明这类农药在浅层地下水中残留已不多；亚硝酸盐、氨氮等超标严重，说明农业生产中施用的大量化肥严重影响了浅层地下水水质.Abstract: By analysis on 21 groups of shallow groundwater samples taken from Jiansanjiang Farm in Sanjiang Plain, they are classified into three types by water quality, including 1 group of Type Ⅲ, 11 groups of Type Ⅳ and 9 groups of Type Ⅴ. Organic pollutants from 13 groups of samples are detected, but not exceed standard. Generally, the groundwater in paddy field of Jiansanjiang farm is seriously polluted, with most groundwater belonging to Ⅳ and Ⅴ types, not suitable for drinking. Affected by original geological environment, part of groundwater contains overproof Fe and Mn. The reason for exceeding volatile phenol and Pb is yet to be identified. Organochlorine pesticide is not detected, indicating that this type of pesticide residue in shallow groundwater is not much. NO2-, ammonia nitrogen and other elements as well are seriously exceeded, showing that large amount of fertilizer applied in agricultural production significantly impacts the quality of shallow groundwater.
