Embodiment 1
[0051] An industrial wastewater treatment system based on high-salt wastewater, including a cyclic resin adsorption unit, a multi-electrode multi-diaphragm electrolysis unit, a reverse osmosis unit, a membrane distillation unit, and an evaporation crystallization unit. The cyclic resin adsorption unit includes multiple resin adsorption subunits The interior of the resin adsorption sub-unit is filled with renewable resin particles 5. First, resin adsorption is used to remove hardness and a small amount of organic matter in high-salt wastewater, and then multi-electrode and multi-diaphragm electrolysis can be used to remove the salt in high-salt wastewater more thoroughly. Reverse osmosis is used to further concentrate the high-salt wastewater after hardness removal to obtain reverse osmosis product water and reverse osmosis concentrated water. The reverse osmosis concentrated water is further concentrated by membrane distillation to obtain membrane distillation product water and ...
