摘　　要：全流程钢厂固废种类多、数量大,委外处置成本高且存在一定的风险,钢铁厂可通过本单位具有高温高压还原氧化特性的冶金窑炉开展固废的资源化利用工作。脱硅污泥和含油污泥有较强的酸性和碱性,但含铁量也较高,酸碱中和后返烧结配矿,不仅可以充分利用铁元素,还可以有效减少固废排放量。The solid waste of full process steel mills is diverse and large in quantity,and the outsourcing disposal is costly and risky.The iron and steel plants can carry out the resource utilization of solid waste through their metallurgical kilns with high temperature and high pressure reduction and oxidation characteristics.Desilication sludge and oily sludge have strong acidity and alkalinity,but also high iron content.Thus,if return those sludge back to the sintered ore after acid and alkali neutralization,it can not only make full use of iron,but also can effectively reduce solid waste emissions.
