含砷高铁废水处理研究现状
Research Progress of the Treatment of High Iron Arsenic Wastewater
摘要
Abstract
High iron arsenic wastewater is produced by sulfated roasting -water leaching in the smelting industry. The wastewater is highly acidic and contains massive Fe2+and SO42- as well as a spot of As3+, Cu2+, Zn2+and Cd2+ions. This article systematically introduces the technical methods,process flow and the latest research progress of the treatment for the high iron arsenic wastewater. At present, the treatment methods mainly include neutralization precipitation, sulfide precipitation,ion exchange,iron powder reduction and biological flocculation. The process route as well as the advantages and disadvantages of these methods are compared in detail. Moreover, the industrial applications of the wastewater in the preparation of inorganic polymer flocculants, mag-netic nano-materials,iron oxide pigments and other products are introduced.关键词
