摘要
详细介绍了废硫酸的来源及其回收利用情况,分析了废硫酸的处理、处置现状,旨在为废硫酸的综合再利用途径提供新思路。废硫酸的来源十分广泛,主要包括钛白粉废酸、钢铁酸洗废酸、染料废酸、铅酸蓄电池废酸、烷基化废酸、氯碱废液等。废硫酸可通过制备硫酸铵肥料、硫酸、石膏、污水处理剂等实现回收再利用,这样既能保护生态环境,又可以实现资源再利用。
The sources of waste sulfuric acid and its reusing were provided detailed description,which also comprehended the current status of the treatment and disposal of waste sulfuric acid,and provided new ideas for the utilization of waste sulfuric acid.The sources of waste sulfuric acid are mainly included waste acid from titanium dioxide production,waste acid from steel pickling,waste acid from dye production,waste acid from lead-acid battery,waste acid from alkylation,and waste acid from chloralkali,and so on.Waste sulfuric acid can be recycled by being processed into ammonium sulfate fertilizer,sulfuric acid,gypsum,sewage treatment agents,and other products.This approach not only protects the ecological environment but also enables resource reuse.
