铬渣渗滤液处理方法及应用现状

Technology of Leachate Treatment of Chromium Residue

铬渣产量大、毒性剧烈,是严重污染环境和危害人类健康的危险废物。铬渣的环境污染问题已经引起了国家的高度重视,要求2010年底前,所有历史堆存铬渣实现无害化处理。铬渣堆放所产生的含铬渗滤液已对周围的土壤、地下水乃至居民身体健康造成危害。因此,在铬渣得到治理的同时,含铬渗滤液必须得到有效治理。系统评述了铬渣渗滤液的各种治理技术和应用现状,并展望了含铬废水处理技术的发展前景。

Chromium residue is one of the most hazardous residues that has a large annual output.The problem of environmental pollution caused by chromium residue has caught high concern from our National Authority.It is required that by end of 2010 all stacked chromium residue should realize innocuity.The chromic leachate resulting from stacked chromium residue has polluted the soil,nderground water,even threatened people＇s heath.Therefore,chromic wastewater should be treated during disposal of the chromium residue. This article introduced the processing method of the chromic leachate, the application and the trend.The treatment technology prospects of the chromic leachate was prospected.
