摘　　要：采用硫酸法生产钛白，每生产1t钛白约产生质量分数20%左右的废酸6～8t。为了解决废酸污染及回收利用问题，国内外科技工作者开发了多种治理工艺，如中和，废酸再生，废酸浓缩等。分析各工艺的优缺点，对开展新的废酸治理工艺研究有一定借鉴和指导意义。When produce 1 ton of titanium pigment,there is 6-8 t method. In order to solve the problem of waste acid,many scientis processes, for on. The advan example, neutralization process, recycle of waste acid, tages and disvanta craftwork of decreasing the poll ges of each craftwork ution caused by the w waste acid by using sulphuric acid ts have empoldered many disposal concentration of waste acid and so are analysed. It is meaningful for developing new aste acid.
