摘要

中国磷化工企业渣酸、萃余酸产量日益提高,但受限于渣酸和萃余酸杂质(阴离子、阳离子)含量高及萃余酸黏度大等因素,使其利用率存在一定的上限,实现渣酸和萃余酸的高效、增量利用已成为磷化工产业健康发展面临的迫切难题。介绍了渣酸、萃余酸的来源及主要性质;全面阐述了萃余酸净化的研究进展,归纳总结了现有的净化方法,主要包括络合净化法、酸碱调节法、膜过滤法等;梳理了渣酸和萃余酸综合利用研究及应用进展:利用渣酸和萃余酸制备精细磷化工产品、制备农用肥料产品及在其他化工领域中的应用。并对未来渣酸和萃余酸高效利用应关注的研究方向和内容进行了展望。以期为提高渣酸和萃余酸等副产资源利用率、推动肥料产业转型升级和绿色发展提供参考。

Abstract

The production of sludge acid and raffinate acid in phosphorus chemical enterprises is increasing day by day in China.However,due to the high content of impurities(anion and cation) and the high viscosity of raffinate,the utilization rate of sludge acid and raffinate acid has a certain upper limit.It has become an urgent problem to realize efficient and incremental utilization of sludge acid and raffinate acid for the healthy development of phosphorus chemical industry.The sources and main properties of sludge acid and raffinate acid were introduced.The research progress of purification of raffinate was described,and the existing purification methods were summarized,including complex purification,acid-base regulation,membrane filtration,etc.And progress of comprehensive utilization of sludge acid and raffinate acid were also reviewed,including preparation of fine phosphorus chemical products,preparation of agricultural fertilizer products and application in other chemical fields.The future research direction and content of the efficient utilization of sludge acid and raffinate acid were prospected,so as to provide reference for improving utilization rate of by-product resources such as sludge acid and raffinate acid,promoting transformation and upgrading of fertilizer industry and green development.
