氯碱生产高盐废水深度处理技术的研究及应用

Research and application of advanced treatment technology for high-salt wastewater from chlor-alkali production

介绍一种氯碱生产中高盐废水处理新工艺——碱性废渣处理—化学除硬—沉降分离—双膜浓缩—分质回用。运行证明:采用该工艺建成的废水处理装置可实现零液排放,具有良好的经济效益和环保效益。

A new process for the treatment of high-salt wastewater from chlor - alkali production was introduced. The process was comprised of treatment of alkaline waste residue, water softening by chemicals, sedimentation separation, concentration by double membrane, and graded reusing. The operation proved that the wastewater treatment device built according to this process could realize zero liquid discharge, and had good economic and environmental benefits.
