【摘要】 贵州磷化工产业历经五十多年发展已经取得了令人鼓舞的成绩,但产品附加值不高、精细化程度低、资源利用价值有待提高;同时过度依赖硫磺资源、磷石膏处置环保压力大等因素制约其发展;针对目前面临问题,结合贵州磷、煤资源优势提出用硝酸分解磷矿工艺来进行资源利用,实现产业结构调整,达到提高经济效益、改善环境的目的。更多还原

【Abstract】 After more than fifty years development,the phosphorus chemical industry in Guizhou has achieved excellent progress,however,the added value of the product is not high,the degree of fineness is low,and the utilization value for resource should be improved;also,over-rely on sulfur resource,and big environmental pressure on phosphogypsum disposal also restraint its development;for the current problems,and considering the phosphorus and coal resource advantages of Guizhou,it is proposed to utilize phosphorite with nitric acid decomposition process for resource utilization,so as to realize industrial structure adjustment,enhance economic benefit,and improve the environment.更多还原
