Description

Quick biological denitrogenation equipment of sewage

Technical Field

The utility model relates to the field of sewage treatment, in particular to a rapid biological sewage denitrification device.

Background

The biological denitrification refers to a process of converting organic nitrogen and ammonia nitrogen in sewage into nitrogen gas through ammoniation, nitration reaction and denitrification reaction under the action of microorganisms, and the whole process has the advantages of economy, effectiveness, easy operation and no secondary pollution and is widely applied at present.

In the biological denitrification process, the sewage firstly converts organic nitrogen into ammonia nitrogen through ammoniation in an anaerobic environment, then converts the ammonia nitrogen into nitrate nitrogen through nitrification in an aerobic environment, and then converts the nitrate nitrogen into ammonia gas through denitrification in an anoxic environment to escape from water.

In the nitration reaction process, when sewage is injected into an aerobic environment from an anaerobic environment, part of impurities such as particulate matters remain in the sewage, and after the impurities sink to the bottom of the substrate nitration reaction tank, the impurities are accumulated into a layer of material mold to cover the exposure of oxygen, so that the oxygen cannot react with nitrate nitrogen in time, and the nitration reaction process is relatively long.
