陕西省交口抽渭灌区劣质地下水的资源化研究

RESEARCH ON RESOURCELIZATION OF INFERIOR GROUND WATER IN JIAOKOU IRRIGATION AREA

针对陕西省交口抽渭灌区灌溉渠网纵横 ,灌溉期渭河水源水量不足的实际 ,提出开采当地微咸与咸的地下水 ,注入引水渠道 ,使地表水与劣质地下水在渠道内混合 ,搭载淡水降低地下水的矿化度 ,增大供水水量 ,从而使部分劣质地下水直接资源化。其思路对西北及其他高矿化度地下水分布区 ,有引淡水条件的地区将具有实际意义 ,对扩大地下水资源的范围也将产生一定的影响。

There are many channels and trenches in Jiaokou irrigation area of Shaanxi province, while the supply of water can not meet the need in period of irrigation, and the ground water keep high minerralization degree. The paper presents the measure of resourcelizating ground water to increase water quantity and to decrease mineralization degree of ground water, of which the inferior ground water are exploited in local area, and are mixed with the surface water in channels. The thought is useful to develop ground water resource in areas with high ground water with high minerralization degree and of fresh surface water.
