| description | The utility model relates to the related technical field of sewage treatment, in particular to a novel landfill leachate denitrification device. Comprising a water tank, a reactor and a secondary sedimentation tank, a first anoxic zone, a first aerobic zone, a second anoxic zone and a second aerobic zone are sequentially arranged in the reactor from one end to the other end, and a first overflow port is formed in the lower end between the first anoxic zone and the first aerobic zone. According to the utility model, carbon source equipment in a traditional device is removed, and a carbon source is not added any more, so that the occupied space of the device is reduced, and the required cost is reduced; and in the second anoxic zone, co-denitrification in one zone is realized through heterotrophic denitrification of denitrifying bacteria and autotrophy of anaerobic ammonium oxidation bacteria, so that the purpose of efficient and deep denitrification is achieved. By adding the k3 polyethylene suspended filler, |
