典型化工废盐成分特征与利用处置技术

Typical Chemical Waste Salt Composition Features and Utilization and Disposal Technologies

我国化工废盐有填埋处置、厂内再生利用与“点对点”综合利用三条消纳路径,资源化利用是消纳化工废盐的长期发展方向。从我国典型化工废盐的成分特征出发,以安全消纳为最终目的,总结了目前我国化工废盐利用处置技术的研究与应用现状,并从技术落地之前的废盐管理方面提出建议。以期为废盐管理、废盐利用处置技术的开发与优化提供参考。

There are three consumption paths for chemical waste salt in China,landfill disposal,in plant recycling and"point-to-point"comprehensive utilization.Resource utilization is the long-term development direction for the consumption of chemical waste salt.Starting from the composition characteristics of typical chemical waste salt in China,with the ultimate goal of safe disposal,the current research and application status of chemical waste salt utilization and disposal technology in China are summarized,and suggestions for waste salt management are proposed before the technology is implemented.It is expected to provide a reference for the development and optimization of waste salt management,waste salt utilization and disposal technology.
