摘要：

硫酸法钛白粉废水含有大量的废酸,通常利用石灰制成的氢氧化钙乳浊液进行中和处理。电石渣是氯碱行业产生的废渣,主要成分为氢氧化钙,理论上可以替代石灰作为硫酸法钛白粉废水治理的药剂使用。实验通过对比石灰和电渣处理硫酸法废水的效果,分析电石渣替代石灰的技术可行性,为废物的利用寻求一个合理的途径。

Abstract:

The acid wastewater from TiO₂ contains lots of discard acid and it is commonly treated with the application of lime which is neutralized by Ca(OH)₂ emulsion. Carbide slag is a kind of discard solid produced from chloro-alkaline industry and its main product is Ca(OH)₂. In theory, carbide slag can replace lime to treat acid wastewater from TiO₂. They try to compare the lime and carbide slag which are both used to treat acid wastewater from TiO₂, in order to analyze the feasibility of the application of carbide slag instead of lime. By doing this, they try to find another way to reuse the waste reasonably.

Key words: wastewater treatment, titanium dioxide, carbide slag
