Discussion on Treatment Technologies for Mercury-Containing Wastewater
Thread Content
During the production of vinyl chloride, mercury-containing wastewater and waste alkali solutions are generated. If the pH of the waste alkali solution is not adjusted to 7, sodium hydrosulfide is added directly to remove mercury. Will it affect the mercury removal efficiency?
If it is too acidic, sodium hydrosulfide directly produces hydrogen sulfide, and as a result the operator dies. . . . . If it’s slightly alkaline, that’s fine
