中水水库对地下水环境的影响分析

地下水为支撑社会经济可持续发展的重要战略资源，中水水库对地下水环境的影响分析研究是保障地下水安全的重要手段和前提。文章以典型中水水库彩虹湖为例，分析其水库水源及水文地质条件，并对水库水质及周边地区地下水环境质量现状进行调查、取样与检测，研究其水质现状，进一步了解中水水库对周边地下水影响程度及范围。结果表明：除TN外，地下水中COD、TP、BOD及氨氮含量远低于中水水库中的含量，且各项指标在时间上和空间上变化不明显；通过对中水水库与地下水各指标含量的相关性分析显示，该中水水库对周边地下水影响较小。

Analysis of the impact of the reclaimed water reservoir on the surrounding area groundwater

Groundwater is important strategic resources that support sustainable social and economic development, and the analysis of the impact of the reclaimed water reservoir on the surrounding area groundwater is an important means and premise to ensure the safety of groundwater. Rainbow Lake as a typical reclaimed water reservoir is selected as an example in the paper. The sources of the reclaimed water reservoir and the geological conditions are introduced. The water quality of the reclaimed water reservoir and the environmental quality of surrounding groundwater have been researched, and water samples has been collected, tested and analyzed. The water quality status is learned, and the impact of the reclaimed water reservoir on the surrounding groundwater is further studied on the level and scope. The results show that the groundwater COD, TP, BOD and ammonia nitrogen content is much lower than the water in the reservoir except for TN, and each index changes insignificantly in terms of time and space. The correlation analysis of each index content between the reclaimed water reservoir and the groundwater shows that the reclaimed water reservoir has less impact on the surrounding groundwater.
