摘要
基于温潮减河沿线水文地质条件,在18个地下水质监测点进行采样与分析。以GB/T 14848—2017《地下水质量标准》为依据,选取19项评价指标,采用单因子评价法、规范法和物元可拓法对场区沿线地下水环境现状进行评价。结果表明:地下水中氟化物、耗氧量、总硬度、锰、硝酸盐氮和砷等指标存在超标现象,说明地下水已经受到了一定程度的污染,需要加强地下水水质动态监测。本研究为其他类似工程的设计提供参考。
Based on hydrogeological conditions along the Wenchao canal,18 groundwater samples were collected in monitoring wells for laboratory analysis.According to Standard for Groundwater Quality(GB/T 14848-2017),19 evaluation indexes were selected.In addition,single factor evaluation,normative and matter-element extension method were used to evaluate the groundwater environment status.Results showed that fluoride,oxygen consumption,total hardness,manganese,nitrate nitrogen and arsenic in groundwater exceeded the standard,indicating that groundwater has been polluted to a certain extent.Therefore,it is necessary to conduct strengthened monitoring of groundwater quality dynamic,which could provide reference for the design of other similar projects.
