Abstract

The invention discloses a biological agent for treating ammonia-nitrogen wastewater. According to the formulation, the biological agent is prepared from 10-15 parts of N-fatty acyl amino acid salt, 12-30 parts of dipotassium phosphate, 2-15 parts of glucose, 20-25 parts of silica gel powder, 3-8 parts of ammonium sulfate, 1-4 parts of polyvinylpyrrolidone, 30-50 parts of mixed bacterium liquid and 15-25 parts of water. All microorganisms are reasonable in compatibility, coexist and coordinate, and do not generate antagonism, the biomass is large, and reproduction is fast.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a biological preparation for ammonia nitrogen wastewater treatment. Background technique [0002] Ammonia nitrogen refers to the free ammonia (NH 3 ) and ammonium ions (NH 4 + ) in the form of nitrogen. The nitrogen content of animal organic matter is generally higher than that of vegetable organic matter. At the same time, 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 combined ammonia existing 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.
