The invention relates to the technical field of wastewater treatment, and discloses a bacterial residue anaerobic digestion wastewater treatment system, comprising a reaction tank 1, a sedimentation tank 1, a reaction tank 2, a sedimentation tank 2, a reaction tank 3, a sedimentation tank 3, a sampler, COD meter, metering tank 1, metering tank 2, metering tank 3, metering tank 4, metering tank 5, computer, USAB reactor, anaerobic tank, aeration tank and sedimentation tank 4. The bacterial residue anaerobic digestion wastewater treatment system uses chemical precipitation to remove ammonia nitrogen, uses magnesium chloride and disodium hydrogen phosphate, and uses NaOH to adjust the pH in the reaction process to remove ammonia nitrogen in wastewater. The ammonia nitrogen content in the wastewater is reasonably added, and the proportion of chemical agents is strictly controlled by the computer to improve the ammonia nitrogen removal efficiency. |
