AI Technical Summary

Technical Problem

In pharmaceutical wastewater treatment, the Fenton process suffers from problems such as large reagent dosage, high operating costs, insufficient fluoride removal capacity, and cumbersome traditional process flow, large footprint, and difficulty in achieving stable discharge compliance.

Method used

The Fenton coupled complexation treatment system, including a catalytic mixing reactor, a two-compartment reaction tank and an intelligent control system, is adopted. It integrates oxidation and decontamination by magnetization to enhance Fenton oxidation and complexation sedimentation to remove fluoride. The system also features quantitative dosing of reagents and real-time monitoring to optimize reaction parameters.

Benefits of technology

The process is simplified, reducing drug consumption and land area, improving treatment efficiency, adapting to the stable and compliant discharge of wastewater from pharmaceutical industrial park wastewater treatment plants, and reducing operation and maintenance difficulties and construction costs.
