PREPARATION OF WASTE WATER CONTAINING SODIUM CHLORIDE FOR USE IN CHLOR-ALKALI ELECTROLYSIS

摘要

The present invention relates to be used to prepare waste water sodium chloride-containing. The method is characterized in that, obtains a kind of sodium-chloride water solution, passes through the acidification of particular order, extraction, alkalization and stripping step. Sodium chloride solution then can be used and be immediately available for chloric alkali electrolysis.
