重金属污水处理的研究与发展

对重金属污水处理的各种方法分别进行分析，指出其不足之处。并对生物处理重金属污染技术重点介绍，该技术是未来重金属污水处理的主要方法。生物技术具有原料丰富、效率高、成本低、环境友好无污染等优点。现阶段，很多生物技术尚处于实验室阶段，大规模应用于工业重金属污水处理还需要进一步的研究和发展。 

Research and Development of Treatment Technique of Sewage with Heavy Metals

Some treatment techniques of sewage which was polluted by heavy metals were analyzed and their defects were indicated.Biotreatment technique for heavy metals pollution was introduced.This technique will be a principal method in the future. It had lots of advantages，such as abundant raw material，high efficient，low cost，eco-friendly，non-pollution and so on.At the present stage，this technique remains in the laboratories.It need be further researches and development for applying to industry treatment about sewage which was polluted by heavy metals.
