AI Technical Summary

Technical Problem

Existing technologies are difficult to effectively treat high-salt, high-concentration industrial wastewater. Traditional methods are costly and inefficient, and catalysts are prone to deactivation in high-salt media, resulting in incomplete treatment and increased treatment costs.

Method used

The MVR-TFO coupled process is adopted, which uses an MVR evaporator to concentrate, crystallize, desalinate, and remove large molecular organic matter, and combines it with a targeted Fenton oxidation reactor to carry out hydrothermal oxidation in the presence of Fe/ZSM5 catalyst, thereby achieving efficient decomposition of organic matter.

Benefits of technology

It achieves green and energy-saving treatment of high-salt, high-concentration industrial wastewater, improves COD and salt removal rates, meets emission standards, and reduces energy demand and waste treatment costs.
