Abstract

Yellow water is the blind ditch water produced in Baijiu fermentation pool, which has the characteristics of high chemical oxygen demand (COD) concentration, poor biodegradability and difficult degradation. The pulse light Fenton integrated sewage treatment scheme designed in this project has a comprehensive COD removal rate of over 98%. After treatment, it can meet the Class A standard of the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" and be directly discharged. Firstly, by pre treating yellow water with pulsed light, the B/C ratio can be increased from 41.8% to 71.3%; After anaerobic and aerobic biochemical treatment, the COD concentration has significantly decreased; Finally, pulsed light Fenton treatment can degrade COD to below 50 mg/L, Amount of ferrous and H2O2 is also significantly reduced.
