含铬废水处理工艺的研究热点及其绿色化发展趋势

Research Focus and Green Development Trend on Treatment of Waste Water Containing Chromium in Leather Industry

皮革行业为国民经济的发展做出了重大贡献,但同时其生产过程中排放的废水也对环境造成了一定的污染,对其产生的废水进行处理在当今绿色环保的主题下显得愈加重要。废水以铬盐最具毒性,也较为难处理。含铬废水的处理工艺众多,工艺各有特点。本文对近年来各工艺处理机理进行了简要的阐述,着重探讨了含铬废水各种处理工艺的优点与存在的问题,并展望了含铬废水处理技术的发展趋势。

Leather industry make contribution to development of national economy, and cause contaminations for waste water discharged to environment, so waste water treatment in the production process seems very important on the theme of green environmental protection. Chromium salt in the waste water is the most toxicity, and difficult to treatment. There are many different characteristics of treatment processes to the waste water. Some mechanism of the treatment processes were briefly described, advantages and existing problems of the treatment processes were discussed, and development trend was prospected also in this paper.
