Description

technical field

[0001] The invention belongs to the technical field of microorganisms, and discloses a biological preparation for treating ammonia nitrogen sewage and a preparation method thereof. Background technique

[0002] Ammonia nitrogen refers to nitrogen in water in the form of free ammonia (NH3) and ammonium ions (NH4+). The nitrogen content of animal organic matter is generally higher than that of plant organic matter. At the same time, the nitrogen-containing organic matter in human and animal manure is very unstable and easily decomposed into ammonia. Therefore, when the content of ammonia nitrogen in water increases, it refers to the compound ammonia that exists in the form of ammonia or ammonium ions. The characteristics of ammonia nitrogen sewage are that the pollutants are mainly ammonia nitrogen, the COD content of the pollutants is relatively high, the organic matter content in the water is relatively small, and the biodegradability is relatively poor. ...
