INQUIRY

Biological contact oxidation process is a biological magic process between activated sludge process and biological pond, which is characterized by setting fillers in the pond, aerating the bottom of the pond to fill the sewage, and making the sewage in the pond in a flowing state, so as to ensure full contact between the sewage and the fillers in the sewage and avoid the defect of uneven contact between the sewage and the fillers in the biological contact oxidation pond. The basic principle of purifying wastewater is the same as that of general biofilm process, which uses biological adsorption of organic matter in wastewater.
