The sedimentation treatment is a primary treatment and the biological treatment is a secondary treatment. The core idea is denitrification treatment, sewage denitrification is realized mainly by a biological method, and the core is two biological enzymatic reactions of nitrification and denitrification which are related to each other. In the nitration reaction, the oxygen oxidizes ammonia nitrogen into nitrate nitrogen under the catalysis of biological enzyme secreted by nitrifying bacteria; in the denitrification reaction, the carbon source reduces nitrate nitrogen into nitrogen under the catalysis of biological enzymes secreted by denitrifying bacteria, and the nitrogen escapes from water to realize the aim of sewage denitrification.
