一、前言随着工业生产的发展,排除的废水、废气、废渣就日益增多,这已成为一项迫切需要解决的严重问题。目前,湘钢钢渣已成为渣害,如不及早解决,钢渣就占用大量农田,影响工农业生产。毛主席、党中央对环境保护极为重视,省委领导同志抓的很紧,要求“三、五年内达到控制,十年内达到根治”,我们坚决执行。湘钢平炉水冲渣(初期渣) 含铁量约为35～45％,其中含有6～7％的金属铁,余者均为氧化铁,如能充分利用这一废渣资源,
I. Introduction With the development of industrial production, the removal of waste water, waste gas and waste residue is on the rise. This has become a pressing issue that needs urgent solution.
