摘　　要：通过对钛白粉生产过程中产生的废固渣水解垢的性质分析,提出了“湿球磨解聚-漂洗净化-回收利用”的工艺路线,实现水解垢高效率高质量回收利用生产钛白粉,达到与正常偏钛酸同等的经济价值的目的。该技术既解决了钛白粉废固安全处理问题,又实现了经济效益,对整个硫酸法钛白粉清洁生产技术开发和提升具有重要意义,行业推广意义重大。Through the analysis of the properties of the solid waste hydrolysis scale produced from the titanium dioxide production,a technical route of“wet ball grinding depolymerization-rinsing purification-recovery and utilization”was proposed to achieve reproduction of titanium dioxide high efficiency and high quality from the recovery of hydrolysis scale while also reach the equivalent economic benefits as the production from titanic acid.This technology acquires the disposing security of solid waste and gains extra profits at the same time.This technology is significant to prompt the development of the entire sulfuric acid process of titanium dioxide clean production technology.
