Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0046] The "functional bacteria" in the present invention refers to the general term of ammonifying bacteria, nitrifying bacteria, and denitrifying bacteria required in the denitrification reaction.

[0047] refer to figure 1 , a method for precisely controlling denitrification, comprising the following links:

[0048] S1, ammonification link, using ammonification bacteria to convert organic nitrogen in sewage into ammonia nitrogen;

[0049] S2, the nitrifica...

Abstract

The invention provides a method and equipment for precisely controlling denitrification, relates to the technical field of sewage treatment, and solves the technical problem of low reaction rate in the denitrification process in the prior art. The invention accurately controls the denitrification method including the ammonification link, using ammonification bacteria to convert organic nitrogen into ammonia nitrogen; using nitrification bacteria to oxidize ammonia nitrogen in sewage into nitrate and / or nitrite, and then making the sewage enter the degassing link Volatilize and / or consume the oxygen in the sewage; the sewage after the degassing process is mixed with the sewage after the ammonification process, and the nitrate and / or nitrite is converted into nitrogen by denitrifying bacteria. Precise control of denitrification equipment includes anaerobic zone, anoxic zone, aerobic zone and degassing reflux zone, anaerobic zone is connected with anoxic zone, anoxic zone is connected with aerobic zone, degassed reflux zone is connected with aerobic zone and The anoxic area is connected, so that each link and / or area forms a better ecological environment for functional bacteria.

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...
