一种钛白粉废酸综合利用方法
摘要：
一种钛白粉废酸综合利用方法，将钛白粉废酸作为Fenton试剂的组成部分用于Fenton氧化法废水深度处理工艺中；所述的钛白粉废酸为硫酸钛水解后过滤产生的废酸，或者硫酸钛水解后过滤得到的偏钛酸经水洗得到的废水，再或者二者的混合。本发明实现了钛白粉废酸得到最大限度的应用，并为污水治理企业节省了大量的硫酸亚铁和硫酸采购费用，没有新增的二次污染物，对污水治理企业而言，最终生成的污泥数量和成份没有发生变化。
摘要（英）：

A comprehensive utilization method of titanium dioxide waste acid adopts titanium dioxide waste acid as a component of a Fenton reagent, and uses the titanium dioxide waste acid in a waste water deep treatment process by a Fenton oxidation method; the titanium dioxide waste acid is waste acid generated by filtering hydrolyzed titanium sulfate, or waste water obtained by washing metatitanic acid generated by filtering hydrolyzed titanium sulfate, or a mixture of the above two. The method of the invention realizes maximum application of titanium dioxide waste acid, saves a lot of ferrous sulfate and sulfuric acid buying expenses for sewage treatment enterprises, generates no new secondary pollutants, and does not change the amount and components of finally generated sludge for sewage treatment enterprises.
