[0005] The high-salt wastewater in the existing industrial wastewater generally requires additional preparation of acid and lye during treatment. In addition, the adsorption resin used to adsorb organic pollutants needs to be regenerated by using high-temperature steam alone after a period of use. treatment, the above series of operations have virtually increased unnecessary costs, and at the same time reduced the treatment efficiency of high-salt wastewater

Embodiment 1
[0050] An industrial wastewater treatment system based on high-salt wastewater, including sequentially connected cyclic resin adsorption unit, multi-electrode multi-diaphragm electrolysis unit, reverse osmosis unit, membrane distillation unit and evaporation crystallization unit, the cyclic resin adsorption unit includes multiple resins Adsorption sub-unit, the resin adsorption sub-unit is filled with renewable resin particles 5, firstly use resin adsorption to remove hardness and a small amount of organic matter in high-salt wastewater, and then use multi-electrode and multi-diaphragm electrolysis to make the removal of salt in high-salt wastewater more efficient 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 then deeply concentrated by membrane distillation to obtain membrane distillation product w...

The invention discloses an industrial wastewater treatment system based on high-salt wastewater and a treatment method thereof, belonging to the technical field of industrial wastewater treatment. An industrial wastewater treatment system based on high-salt wastewater includes a circulating resin adsorption unit, multi-electrode and multi-diaphragm Electrolysis unit, reverse osmosis unit, membrane distillation unit and evaporation crystallization unit, the circulating resin adsorption unit includes multiple resin adsorption subunits, and the application of multi-electrode and multi-diaphragm electrolysis between resin adsorption and reverse osmosis can make high-salt wastewater The salt removal is more thorough. The alkali and acid produced by multi-electrode and multi-diaphragm electrolysis can meet the alkali-acid requirements of reverse osmosis and membrane distillation. The shift-type adsorption method of multiple resin adsorption subunits can optimize the resin adsorption effect. The high-temperature water vapor generated by membrane distillation regenerates the resin adsorption sub-unit, which can greatly save the treatment cost and greatly improve the treatment efficiency of high-salt wastewater.
Description
technical field [0001] The invention relates to the technical field of industrial wastewater treatment, and more specifically relates to an industrial wastewater treatment system based on high-salt wastewater and a treatment method thereof. Background technique [0002] High-salt wastewater refers to wastewater with a total salt content of at least 1%. It mainly comes from chemical plants and the collection and processing of oil and natural gas. This wastewater contains a variety of substances (including salts, oils, organic heavy metals, and radioactive substances). Salt wastewater is produced in a wide range of ways, and the amount of water is increasing year by year. The environmental impact of removing organic pollutants in saline wastewater is crucial. Biological treatment is used, and high-concentration salts have an inhibitory effect on microorganisms. Physicochemical treatment requires large investment and high operating costs, and it is difficult to achieve the e...
