饮用水源地重金属溶出的影响研究——以广东石门台水库为例

文章研究对饮用水源地水水质现状进行了全面调查;采集水源地土壤进行浸泡释放实验和模拟酸雨的淋溶实验,结果表明在充分搅拌释放条件下,释放污染物对于水质影响不大;而淋溶实验表明各元素释放强度依次为:Mn>Ni>Cu>Pb>As>Hg;Mn和Ni的淋出液浓度超过了地表水水源地水质标准;pH为3.0和5.6的酸雨对于硫铁矿区重金属的溶出和迁移均是有利条件,pH为5.6的酸雨对于钨矿区重金属的溶出更为有利。

Effect of Heavy Metals Release on Drinking Water Supply Source

Based on investigation of water quality of drinking water supply source, soaking release and leaching experiments were carried out in laboratory. Results indicated that the release of heavy metals in soaking experiment could not affect water quality too much even with acutely stirring. Characteristics of heavy metal release showed that the concentration of Mn and Ni exceeded surface water quality standard. Acid rain with pH of 3.0 and 5.6 will be favorable for release of heavy metals from pyrites ore while pH of 5.6 will affect the release of heavy metals from tungsten ores.
