含镉废水处理研究进展

Progress of the Research on the Treatment of Cadmium-contained Wastewater

介绍了含镉废水的危害,阐述目前国内外含镉废水处理常用技术:化学沉淀法、铁氧体法、离子树脂交换法、电解法、化学氧化法、膜分离法、吸附法、生物法等的研究进展,并说明了各方法的优缺点。变性淀粉作为一种改性吸附剂,其吸附处理效果不逊于合成产品,因此具有广阔的应用前景。

The paper introduced the harmfulness of cadmium-contained wastewater. Recent advances of technology for treatment of cadmium-contained wastewater, including chemical precipitation, ferrite method, ion exchange resin method, electrolytic process, chemical oxidation, membranes separation, adsorption process, biological treatment etc., were reviewed. And advantages and disadvantages of each method was also discussed. As a modified absorbent, modified starch had a better adsorption effect compared with the synthetic products, and it had a much more widely application prospect.
