重金属污染水的双壳处理法初探

根据生物成矿作用原理以及热液生物群与多金属硫化物共生的关系提出了双壳生物治理重金属污染水的可能性.实验模拟结果表明,双壳对某些重金属元素具有很强的富集能力,能够在一定程度上降低环境污染指数,说明双壳处理法治理重金属污染水是可行的,尤其是针对矿山污染水;双壳处理法的实施过程中受重金属离子质量浓度与温度范围的限制,其对不同重金属离子的富集也具有一定的选择性.

Preliminary Research on Treatment of the Polluted Water with Heavy Metal by Bivalves

In the rivers and lakes,the bivalves have strong resistance.Based on bio-mineralization principle and the symbiotic relation between the hydrothermal communities and sulphide deposits,the possibility for the bivalve community treating the water polluted by heavy metal is suggested.According to the results of the experiments on the bivalve treating the polluted water with heavy metal,the paper suggests that the bivalves have strong enrichment ability on the some heavy metals.It can reduce the polluted coefficient.Combining the zoology and habit of the bivalves and bio-mineralization principle,the paper analyzes the process of bivalves community treating the water polluted by heavy metal.This method is certainly feasible,especially to the exploiting mine.However,the application of such treatment is limited by the range of thickness and temperature and the bivalves can be selective for some heavy metals.
