摘要
文章主要介绍了水体及土壤中重金属污染的治理方法,分析了现行化学法、物理化学法、生物法等存在的问题,阐述了矿物法治理重金属污染的优点和缺点,由于环境矿物材料具有原料来源广、加工工艺简单、生产成本低、可循环使用等特点。使矿物法治理重金属污染具有经济、简便、有效且不出现二次污染等优点,必将成为今后污染治理重要发展方向之一。
In this paper, the treating methods of heavy metals in water and soil are introduced. The problems existing in some current methods, such as chemical methods, physical and chemical methods, biological methods are analyzing. The advantages and disadvantages of mineral methods are set forth too. Mineral material have some characters, such as, the sources of its raw material is extensive, the machining process is simply, the producing cost is low, and it can be used circularly. So mineral methods are economical, simple, effective and no second pollution. They will be important direction of pollution treatment in future.
