三聚氰胺生产中废渣回收利用的研究进展

Research Progress of Recovery and Utilization of Solid Sludge in Production of Melamine

三聚氰胺是一种重要的化工中间体,尿素法生产三聚氰胺过程中会排放出大量的固体废弃物,既污染环境又浪费资源。利用三聚氰胺生产过程中排放的废渣,回收其中的有效成分或制成有用的化工产品,本文对此进行了综述。

Melamine is an important chemical intermediate. In production of melamine by urea method, large amount of solid waste will be discharged which causes environmental pollution and loss of resource. The recovery of effective constitutes from the solid waste and preparation of chemical products through transformation are both reviewed.
