公路施工过程对饮用水源地污染防治与控制策略研究

Research on Pollution Prevention and Control Strategies for Drinking Water Sources during Highway Construction

研究对花莞高速公路沿线的饮用水水源地和河流进行采样,通过分析水体中的pH、TDS、EC、不同类型的阴阳离子的含量和分布,研究在不同季节和温度条件下,公路施工过程对河流和饮用水源地的污染和影响范围,通过Piper图分析不同季节的饮用水和地表径流的离子类别和含量所占比例。研究发现水体TDS值先增后稳再降,整体满足淡水标准(<1000 mg/L)。公路施工对饮用水源地的污染控制手段有公路路线的合理规划,避开水源地,并优化停车区和服务区等位置。同时推广绿色和先进工艺,减少污染物排放,为公路施工中的水体保护提供科学依据和实用建议。

This study sampled drinking water sources and rivers along the Huaguan Expressway.By analyzing the pH,TDS,EC,and the content and distribution of different types of anions and cations in the water,the pollution and impact range of the road construction process on rivers and drinking water sources under different seasons and temperature conditions were studied.The ion categories and proportions of drinking water and surface runoff in different seasons were analyzed using a Piper plot.The study found that the TDS value of the water body first increased,then stabilized,and then decreased,overall meeting the freshwater standard(<1000 mg/L).The pollution control measures for drinking water sources during highway construction include reasonable planning of highway routes,avoidance of water sources,and optimization of parking and service areas.The study promotes green and advanced technologies to reduce pollutant emissions,providing scientific basis and practical suggestions for water protection in highway construction.
