| titleOfInvention | A kind of AB-ASBR reactor starts the technology of anaerobic ammonium oxidation |
| abstract | The invention belongs to the field of biological treatment of sewage sludge, and relates to a process for starting anaerobic ammonium oxidation in an AB-ASBR reactor, which comprises the following steps: firstly, the return sludge of an urban sewage treatment plant is used as inoculation sludge, and injected into the AB-ASBR for reaction Adsorption and degradation reactions are carried out in the front and back ASBR reactors of the anaerobic ammonium oxidation device; when the sludge is granulated, NH 4 + ‑N and NO 2 ‑ ‑N are added to the front ASBR reactor, The initial concentrations were 50mg/L and 40mg/L, and gradually increased to 50mg/L and 20mg/L respectively, so that the concentrations of NH 4 + ‑N and NO 2 ‑ ‑N were increased to 550mg/L and 320mg/L respectively. L, finally achieve anaerobic ammonium oxidation; after the start of anaerobic ammonium oxidation is completed, the organic wastewater containing ammonia nitrogen is anaerobically treated, and the treated effluent and remaining sludge are discharged through the outlet pipe and sludge discharge valve. The process of the invention can realize the removal of high-concentration organic matter and simultaneously remove ammonia nitrogen in waste water, significantly improve sewage treatment efficiency and reduce treatment cost. |
