How to Choose High Salt Wastewater Treatment Process

#High salt wastewater treatment # With the rapid development of the chemical industry, a large amount of high salt organic wastewater has been generated, and it is increasing year by year. Due to its high salt content and difficult degradation, the difficulty and cost of treating high salt organic wastewater have increased.

Due to the high concentration of soluble inorganic salts, recalcitrant organic compounds, and oils in high salt organic wastewater, direct treatment using biochemical methods is costly and difficult to achieve the expected purification effect.

If wastewater is directly discharged, soluble inorganic salts and recalcitrant toxic organic compounds will have serious impacts on soil and water bodies, causing irreversible damage to the environment.

With the development of new resins and the improvement of treatment processes, resin adsorption method is more commonly used to treat high salt organic wastewater from specific industries. This method has the advantages of high removal rate of harmful substances, deep purification, small equipment footprint, simple operation, and comprehensive recovery.

The high salt liquid refining and impurity removal process developed by Haipu Functional Materials pretreats the wastewater before salt evaporation, converting the organic salts in the wastewater into organic acids, and then adsorbing and removing the majority of the organic acids. The tail water after adsorption treatment is basically inorganic salts, and then the salt containing wastewater is concentrated by electrodialysis. This process can greatly improve the stability of the subsequent evaporation system operation, and the adsorbent material is desorbed and regenerated through an eluent. The desorbed organic salts can be returned to the workshop for recycling.

The advantages of this process

1. Deeply removing organic matter from wastewater, reducing COD and chromaticity of adsorbed effluent, can ensure white salt evaporation in effluent, and improve the stability of subsequent evaporation systems;

2. Separate and recycle organic salts from mixed salt to achieve the goal value of turning waste into treasure.

3. Using specially modified adsorption materials, with large adsorption capacity, low equipment investment, and low operating costs;

4. The process flow is simple and can achieve full automation operation, making operation and maintenance convenient.

5. It can achieve multi-layer layout, small footprint, and short installation cycle.
