摘　　要：总结了全球硫酸法钛白粉废硫酸处理利用技术的研究发展情况、最新技术进展。新技术不仅解决了换热器结垢、热能利用低、不能连续运行的问题,而且为企业在废硫酸循环回用的生产加工创造出更好的经济效益。介绍国外公司在中国申请的专利技术,并提出生产技术改进方面的研究,以及对硫酸法钛白废硫酸回收利用的未来政策与市场面发展的思考。Research development and the latest technological advances in spent acid recycle utilization produced during titanium dioxide production by sulphuric acid are summarized. The new technology not only solved scaling in exchanger, low thermal energy and discontinuous operation, but also created better economic benefits from production and processing in the spend acid recycle for enter- prise, Patents applied for by foreign companies in China are introduced, and deliberation on production technology improvement are proposed, as well as future policies of spent acid recycle utilization and market development.
