【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发展磷化工产业,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】 In despite of inspiring result has been achieved by 50 year’s development of Guizhou phosphorus chemical engineering industry,but added value of product was not high,refinement degree was low,utility value of resource should be advanced;while the factors of excess dependence upon resource of sulfur and environmental protecting pressure from phosphogypsum treatment restrict its development.Aim at issues faced to,integrated Guizhou’s resource of phosphorus and coal,it has been suggested that develops phosphorus chemical engineering industry through decomposing phosphorite by nitric acid.So that carries the point of enhancing economic benefits and improving environment,by adjusting industrial structure.更多还原
