河南省浅层地下水水化学特征研究

为了全面反映河南省地下水环境问题及其严重程度,使已有的环境地质调查成果更好地服务于国民经济建设。本文在充分收集前人环境、水文、地质资料的基础上,以重点城市居住区为研究对象,在地下水问题严重区加密取样、核查,并基于含盐量,划分了氟化物、碘化物、锰、铁以及不同水化学类型的分布范围和分布面积;同时将不同年度含盐量进行类比,找出了各地区地下水环境演化过程和污染原因,总结了原生劣质地下水的成因及存在地区;并对河南省开采运用地下水提出有效、切实可行的合理化建议。

Study on hydrochemical characteristics of shallow groundwater in Henan Province

In order to comprehensively reflect the groundwater environmental problems and their severity in Henan Province, and make the existing environmental geological survey results better serve the national economic construction. Based on the full collection of data, this paper takes the residential areas in key cities as the research object, and densifies the sampling verification in the areas with serious groundwater problems. Based on the salt content, the distribution range and area of fluoride, iodide, manganese, iron and different hydrochemical types are divided. At the same time, the salt content in different years is compared to find out the evolution process and pollution causes of groundwater environment in various regions, as well as the causes and existing areas of primary poor quality groundwater. At the same time, it puts forward effective and feasible rationalization suggestions for the exploitation and utilization of groundwater in Henan Province.
