摘要
2011年7月21日,四川省松潘县境内锰矿渣库溃坝,造成涪江锰污染。四川省地质工程勘察院对绵阳的某涪江渗滤取水工程地下水饮用水水源进行同步水质监测。结果表明,由于滤层中泥膜及砂卵石层的吸附、过滤及生物降解作用,地下水并未受到严重影响,符合饮用水标准。这说明傍河渗滤取水作为供水水源具有良好的推广价值。
The break of the manganese slag dam in Songpan County caused the manganese pollution in Fujiang. Water quality monitoring was carried out for the groundwater sources at a percolation water project on Fujiang in Mianyang. The groundwa-ter turned out to meet drinking water standards because of the adsorption and filtration of mud membrane, sand, gravel, and biological degradation. This shows that percolation projects on rivers for water supply deserve spreading.
