Abstract

The invention relates to the field of chemical wastewater treatment, in particular to a cathode and anode bed regeneration waste acid and alkali water treatment device for the chlor-alkali industry. In order to solve the technical problem that the waste acid and alkali water cannot be efficiently contacted with sea salt, which will inhibit the growth rate of new precipitation, and the flow of calcium precipitation into the next sedimentation tank will affect the precipitation of magnesium ions, the present invention provides such a chlor-alkali industrial The cathode and anode bed regeneration waste acid and alkali water treatment device includes a collection assembly, a stirring assembly, and a middle sleeve assembly, etc.; the main support is fixed with a middle sleeve assembly that provides a central collection chamber for sea salt. In this technical solution, a central isolation treatment chamber is added to react the newly introduced waste acid-base water with sea salt, and divert the newly formed sediment to the bilge in time to realize the high-speed growth of calcium precipitation, and at the same time discontinuously The generated precipitates are collected to keep the calcium precipitates in the cabin at a low level and further promote the high-speed growth of calcium precipitates.

Description

technical field [0001] The invention relates to the field of chemical wastewater treatment, in particular to a cathode and anode bed regeneration waste acid and alkali water treatment device for the chlor-alkali industry. Background technique [0002] In the chlor-alkali industry, the residual waste acid and alkali water after the production of the cathode and anode electrolytic beds contains a large amount of divalent metal ions such as calcium and magnesium. The valence ions are subjected to precipitation treatment in sequence, and the remaining wastewater can only be discharged after the next step of wastewater chelation regeneration and recovery process is completed. [0003] At present, the treatment technology for waste acid and alkali water has been gradually improved. In the treatment steps, the bipolar wastewater in the cathode and anode electrolytic beds can be introduced into the sedimentation tank, the pH value is adjusted, sea salt is added, and steam is introdu...
