Abstract

The invention provides a method and a device for accurately controlling denitrification, relates to the technical field of sewage treatment, and solves a technical problem in the prior art that a reaction speed is low in a denitrification process. The method for accurately controlling the denitrification comprises the following steps of: an ammonification link: converting organic nitrogen into ammonia nitrogen by using ammonifying bacteria; after oxidizing the ammonia nitrogen in sewage to nitrate and / or nitrite by using nitrifying bacteria, enabling the sewage to enter a degassing link for volatilizing and / or consuming oxygen in the sewage; and mixing the sewage after the degassing link and the sewage after the ammonification link, converting the nitrate and / or the nitrite into nitrogen by using denitrifying bacteria. The device for accurately controlling the denitrification comprises an anaerobic area, an anoxic area, an aerobic area and a degassing recirculation area, The anaerobicarea is communicated with the anoxic area, the anoxic area is communicated with the aerobic area, and the degassing recirculation area is communicated with the aerobic area and the anoxic area, so that each link and / or area forms a better functional bacteria ecological environment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method and equipment for precisely controlling denitrification. Background technique [0002] Nitrate products are widely used in arms, machinery, steel and other industries, but the wastewater discharged from the production and / or use of nitrite products contains a large amount of nitrate nitrogen. Nitrate and nitrite are nutrients for plants and microorganisms. However, if they are discharged into water bodies, they will cause eutrophication on the one hand, and on the other hand, nitrites are carcinogenic, teratogenic, and mutagenic. . If the nitrite in the discharged wastewater cannot be effectively cleaned and recovered, the discharged wastewater will pose a huge threat to human health. Therefore, cleaning and recycling the nitrite in the discharged wastewater is extremely important to the healthy development of the ecological environment. [0003] Biological d...
