AI Technical Summary
Existing technologies are ineffective in treating wastewater from the production of azo dyes and condensation dyes that are high in concentration, high in chroma, and have poor biodegradability. Traditional processes suffer from low treatment efficiency, high energy consumption, poor stability, and difficulty in meeting standards.
An integrated process of 'enhanced Fenton oxidation + IC anaerobic reactor + anoxic tank - aerobic tank (AO) + membrane bioreactor (MBR)' is adopted to achieve efficient removal of organic matter through Fenton reaction pretreatment, multi-stage biochemical treatment and membrane separation.
It achieves deep degradation of high-concentration dye wastewater, improves the stability and economy of the system, reduces energy consumption, and ensures that the effluent meets discharge standards.
