[0002] Ammonia nitrogen wastewater mainly comes from fertilizers, coking, petrochemicals, pharmaceuticals, food, landfills, etc. When treating nitrogen-containing wastewater, organic nitrogen can be converted into ammonia nitrogen through ammonification, and ammonia nitrogen can be converted into nitrite nitrogen through nitrification, and then into nitric nitrogen. Nitrite nitrogen and nitric nitrogen are converted into nitrogen gas through denitrification, and finally return to nature. In this series of processes, microorganisms play a vital role.
[0003] In order to ensure its environmental protection effect, the existing wastewater denitrification process often relies on microorganisms to denitrify the sewage. The common method is to place multiple microbial culture plates in the denitrification tank, and then pass the sewage into the denitrification tank so that the sewage contacts the microbial culture plates, and the microorganisms denitrify the nitrogen in the sewage.
[0004] However, when the existing microorganisms denitrify the nitrogen in the sewage, the contact between the sewage and the microbial culture plate is relatively fixed, resulting in the best treatment effect for the sewage close to the microbial culture plate, while the sewage at the bottom of the denitrification tank often has the worst denitrification effect. Therefore, when personnel discharge the sewage at the bottom of the denitrification tank, the denitrification often fails to meet the standard requirements, so there are certain deficiencies.
