探讨锰矿区水域重金属污染成因及治理研究

Study on Cause and Control of Heavy Metal Pollution in Manganese Area

锰矿区污染过程包括:开采冶炼过程中产生的废水、降雨径流作用下的溶析、断层涌水形成污染流、选(洗)矿的废水、矿井水排放等,严重污染环境,影响人们身体健康。锰矿区重金属污染的治理上以氧化还原、吸附沉淀、生物富集为主导方向,南山铁矿和江西万年矿山使用中和沉淀法、日本采用氧化铁硫杆菌、胶质芽抱杆菌处理废水等都取得了较好的效果,锰矿区地形多变和重金属种类复杂,我们应当因地制宜,才能高效的治理锰矿区水域污染问题。

The pollution process in the manganese area includes waste water to mining and smelting, pollutant dissolution under rainfall runoff, the polluted stream comes from underground faults, wastewater comes from election （wash） mine, mine water discharge, etc, polluting the environment, affecting people＇s health. The dominant direction of heavy metal pollution control in the manganese area is oxidation-reduction, adsorption precipitation and bioaccumulation, neutralization precipitation is used in Nanshan Iron Mine and Jiangxi Wannian mine, thiobacillus ferrooxidans is used in Japan＇s tailings mines, bacillus sphincter is used to treat manganese ore wastewater, etc, which have achieved good results. Because of the complex terrain and heavy metal content types, the actual situation should be considered, in order to control the manganese mine water pollution problems.
