| 摘 要： | 不锈钢酸洗过程会产生大量的酸洗污泥，干燥后主要含CaF2，Fe2O3，CaO，Cr2O3，NiO等，并含一定量的CaSO4，SiO2，MgO等组分。主要以堆放和填埋的方式处置，目前已开展了制砖、回收金属、生产水泥等研究。总结了不锈钢酸洗污泥资源化利用中存在的问题，并着重就不锈钢酸洗污泥的资源化利用提出见解。

| Abstract: | Pickling sludge was generated in stainless steel pickling process. The major compositions in pickling sludge were CaF2, Fe2O3, CaO, Cr2O3, NiO, CaSO4, SiO2 and MgO after dried. Pickling sludge was treated by solidified landfill. The resource utilization of pickling sludge has been studied on brickmaking, recycling metal and cement production.These treatment processes involves many problems such as pollution transfer,environmental safety of by-product, high processing cost and so on. The paper summarizes the problems existing in the stainless steel pickling sludge recycling and proposes new suggestions on stainless steel pickling sludge recycling. |
