重金属污染水体的高效环保处理技术及研究进展

重金属污染作为影响环境的严重问题之一,不仅因其毒性大、易积累,而且处理后难以回收,对于重金属污染水体的处理技术,大部分仍存在成本高,易造成二次污染等问题。本文综述目前在处理工业废水中重金属离子的多种工艺技术,从环境保护、经济效益角度分析碳黑泥、矿物材料、树脂等的优缺点,提出发展高效环保型的处理技术,包括天然处理剂的应用,如竹炭,壳聚糖,微生物等,为去除重金属、净化水质提供新思路。

Study on Efficient Environmental Protection Technology of Heavy Metal Polluted Water

Heavy metal pollution is one of the serious environmental problem for its toxicity,accumulation,recycling hardly,especially in water treatment,most technical methods have the higher cost and the secondary pollution.The article summarized lots of current ways to deal with the heavy metals ions of industrial wastewater,analyzed advantages and disadvantages of carbon black mud,mineral materials and resins from the environmental and economic viewpoint to propose new ways to study environment-friendly natural treating agents,such as bamboo charcoal,chitosan,micro-organisms and so on,which would provide new idea for heavy metals removal so as to purify water quality.
