Prof. Huang Shaobin and others use the biofilm formed on the surface of the high-efficiency packing combined with aerobic denitrification technology. The organic matter and total nitrogen in the industrial wastewater can be efficiently removed efficiently through the high-efficiency biofiltration system. The solution is provided for the problems of low rate and unqualified total nitrogen in the discharged wastewater of aerobic unit. And found that in the process of aerobic denitrification biological filtration, it can simultaneously remove pollutants such as NOx and residual SO₂ from the flue gas, which is expected to become a new technology of high efficiency flue gas treatment.
