Abstract: China’s sulphuric acid, phosphate fertilizer and titanium dioxide industry came into the period of rapid development from 2006 to 2016. From 2006 to 2016 the average annual growth rate of sulphuric acid production capacity was 9.2% and the average of yield annual growth rate was 6.6%. The average annual growth rate of phosphate fertilizer production capacity was 4.0% and the average of yield annual growth rate was 3.2%. The average annual growth rate of titanium dioxide production capacity was 12.7% and the average of yield annual growth rate was 11.7%. The sulphuric acid production is expected to be about 110 Mt by 2020, the apparent consumption of sulphur resource is about 39.5 Mt, the yield of phosphate fertilizer is expected to remain 18.0 Mt, the yield of titanium dioxide is about 3.1 Mt. The progress of sulphuric acid, phosphate fertilizer and titanium dioxide in recent ten years was reviewed, and the development of sulphur-phosphorus-titanium-iron circular economy industrial chain is summarized. The future of thiophosphate industry must strengthen the technological progress and industry integration development, collaborative solution waste acid, waste residue, waste gas and comprehensive management of resources, comprehensive utilization of energy to achieve sustainable development.

硫酸、磷肥和钛白粉是我国重要基础化工原料，在工农业生产中起着举足轻重的作用。经过“十一五”、“十二五”的快速发展，我国硫磷钛工业装置规模、技术装备水平、清洁生产、节能减排、循环经济等方面都取得长足进步，并且初步构建了硫-磷-钛-铁循环经济产业链，行业之间不断融合发展。在经历“十一五”期间高速发展、“十二五”中低速发展后，“十三五”期间硫磷钛工业既面临产能过剩、产业结构调整、化肥零增长、节能减排、资源能源和核心技术设备突破等挑战，也面临“一带一路”、“中国制造2025”升级等发展机遇，未来的硫磷钛工业将是负重前行、任重道远。……
