Abstract
The invention discloses a method for enhanced denitrification and a device thereof. The device comprises an anoxic tank, an aerobic tank and a carbon source booster connected in sequence, and an output end of the carbon source booster is then connected with the anoxic tank; a plurality of membrane contactors are fixed inside the carbon source booster, the membrane contactor is in a hollow structure, and there is a gap between the membrane contactors and a shell of the carbon source booster. By adopting the device, macromolecular carbon source can be added and hydrolyzed into volatile fatty acids by using the hydrolytic fermentation bacteria existing in the gap between the carbon source booster and the membrane contactors, which then penetrates into the hollow part of the membrane contactors through membrane diffusion, as a small molecular carbon source that can be effectively used by denitrifying bacteria to promote the denitrification process.
