Project Profile:Our company built an electrochemical catalytic oxidation system for wastewater pretreatment. The wastewater is first treated by the electrochemical catalytic oxidation and then entered the subsequent treatment for qualified discharge. The project was put into operation in May 2015 and has been running steadily so far.
The operational water volume of the project is 300m3/d, and the COD of the raw water is about 10,000 mg/L; The color is dark red; the B/C is less than 0.1 with poor biodegradability. After treated by the electrochemical catalytic oxidation system, the COD of the effluent can be reduced to about 5,000mg/L, and the color becomes transparent yellow.
