含铜废水的处理技术及研究进展

随着冶金、电子工业的发展,产生了大量的含铜废水,给人和环境带来了危害,但这些废水又具有一定的经济价值。因此,其排放前必须净化处理并回收金属铜,以实现环境保护和资源循环利用。本文综述了化学法、物化法及生物法处理含铜废水的研究现状及应用情况,评价了各种方法的优缺点。笔者认为,生物法处理技术具备简单、高效、无二次污染等优势,在有效解决生物体颗粒化、固定化、更强的吸附及整治修复能力的条件下,生物法处理技术可望成为工业化处理含铜废水最有效可行的方法。

The Technologies for Treating Wastewater Containing Copper and Research Progress

With the development of metallurgical and electronic industries,a large quantity of wastewaters containing copper ion were produced.Although they do harm to humanity and natural environment,but they have some economic values.Thus,first of all,these wastewaters must be purified and rechaimed before discharging them.This paper reviewed the present situation of research and testwork,and practical application of some physical-chemical,chemical and biological methods in treatment of wastewaters containing copper ions,and analyzed the advantages and disadvantages of various methods.It is believed that as far as removal of copper ion from wastewaters is concerned,the biological treating process is more simple and efficient,and can reduce secondary pollution,furthermore,the copper may be reclaimed.Under the conditions of granulation,fixation,stronger adsorption and restoration of organism can be effectively resolved,the biological treating process will be a effective way for removal of copper from wastewaters.
