Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment nitrification reaction pool. Background Art

[0002] The nitrification reaction in sewage treatment refers to the process in which nitrifying bacteria convert ammonia nitrogen (NH3-N) in sewage into nitrite nitrogen (NO2-N) and nitrate nitrogen (NO3-N). Nitrification is an important step in the sewage treatment process, because ammonia nitrogen can be converted into nitrite nitrogen and nitrate nitrogen in water, which are harmful to humans and the environment. Factors affecting the nitrification reaction include temperature, pH value, dissolved oxygen, organic matter concentration, toxic substances, etc. Temperature and pH value have a greater impact on the nitrification reaction. Appropriate temperature and pH value can increase the rate of nitrification. Dissolved oxygen is also an important factor affecting the nitrification reaction. Adequate dissolved oxygen is conducive to the growth and reproduction of nitrifying bacteria. During the nitrification reaction, if sufficient oxygen can be supplied in real time, the efficiency of the nitrification reaction will undoubtedly be greatly enhanced.

[0003] In view of the above situation, the present utility model is proposed. Utility Model Content
