摘要
地下水作为我们人类生存和发展必不可少的重要资源,其重要性不言而喻。地下水是人类生产生活重要的淡水来源,主要用于饮用、农业灌溉和工业生产用水等。同时地下水也在地球水循环中发挥着重要作用,对于维持地表水径流稳定和生态系统的稳定也起着举足轻重的作用。近年来由于工业生产、农业污染以及生产污水排放等原因,我国地下水受到不同程度的污染。地下水污染具有一定程度的隐蔽性,不能及时被发现。其次,地下水的污染是一个逐步累积的过程。再次,地下水污染具有持久性,污染物在地下水中存在的时间较长,很难被自然降解。最后,由于地下水具有流动性,容易对周边地下水产生影响。一旦发生污染事故,很难像地表水一样采取应急措施阻止污染物的快速扩散。基于以上原因,本文对地下水的污染成因、现状调查及监测方法进行论述。
As an essential resource for human survival and development,the importance of groundwater is self-evident.Groundwater is an important source of fresh water for human production and life,mainly used for drinking,agricultural irrigation,and industrial production water.At the same time,groundwater also plays an important role in the Earth’s water cycle,playing a crucial role in maintaining surface water runoff stability and ecosystem stability.In recent years,due to industrial production,agricultural pollution and production wastewater discharge,groundwater in China has been polluted to varying degrees.Groundwater pollution has a certain degree of concealment and cannot be detected in a timely manner.Secondly,groundwater pollution is a gradual accumulation process.Again,groundwater pollution is persistent,and pollutants exist in groundwater for a long time and are difficult to degrade naturally.Finally,due to the fluidity of groundwater,it is easy to have an impact on the surrounding groundwater.Once a pollution accident occurs,it is difficult to take emergency measures like surface water to prevent the rapid spread of pollutants.Based on the above reasons,the causes,current situation investigation and monitoring methods of groundwater pollution were discussed.
