Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, and more specifically to a membrane combination treatment device applied to high-salinity industrial wastewater. Background Art

[0002] High-salinity industrial wastewater is a type of industrial wastewater containing high salt content, which is difficult to treat. At present, common treatment methods include multi-effect steam evaporation, mechanical advanced steam recompression, advanced steam oxidation, forward reverse osmosis, reverse reverse osmosis, electrodialysis, etc. Existing high-salinity industrial wastewater is usually treated using a membrane combination treatment device, which is a device that uses different membrane combinations to form a membrane assembly for treatment and is widely used in practical projects.

[0003] For example, the prior art publication number CN214032066U is a membrane combination treatment device for high-salinity industrial wastewater. The utility model uses a sedimentation structure and a filtration structure. The wastewater is first mixed with a reagent, then allowed to settle, and the settled substances are collected. The remaining wastewater is subjected to electrodialysis filtration and finally discharged. This solves the problems in the prior art that most of the single membrane separation methods are used, the concentration is not too high, the membrane is seriously polluted and scaled, the process is complex, the energy consumption is high, and it is easy to cause waste of resources.
