The invention discloses a device and a method for synchronous treatment of a high-nitrogen wastewater and municipal sewage by employing ANAMMOX-PD, and belongs to the field of biological treatment of wastewaters. The device comprises a water inlet box, an anaerobic ammonium oxidation reactor, a middle water tank, a carbon source reserve tank and a partial denitrification reactor; and the operation method comprises the following steps: feeding the high-nitrogen wastewater into the anaerobic ammonium oxidation reactor; removing nitrite nitrogen and ammonia nitrogen in inflow; feeding the wastewater containing excessive nitrate nitrogen to the partial denitrification reactor; simultaneously pumping a certain amount of municipal sewage; restoring nitrate nitrogen into nitrite nitrogen by denitrifying bacteria by virtue of organic matters in domestic sewage; and refluxing effluent containing nitrite nitrogen and ammonia nitrogen to the anaerobic ammonia oxidation reactor to denitrify. According to the device and the method, the nitrogen concentration of the effluent of anaerobic ammonia oxidation can be greatly reduced, the target of deep denitrification by using a high-concentration nitrogen wastewater is achieved, and the organic matter and ammonia nitrogen in the municipal sewage are synchronously removed. The device and the method are convenient to operate, simple in control, and high in nitrogen removal rate, and the cost can be greatly reduced.
Description
Technical field: [0001] The invention relates to a method for synchronously treating high-nitrogen waste water and urban domestic sewage by using anaerobic ammonium oxidation and partial denitrification technologies, belonging to the technical field of sewage biological treatment. In this method, the carbon source in urban domestic sewage is used as the electron donor, and the NO in the effluent of the high-nitrogen wastewater anammox reactor 3 - -N reduction to NO by partial denitrification 2 - -N, and the ammonia nitrogen in urban domestic sewage is removed by anaerobic ammonium oxidation. This method not only realizes the deep denitrification of the anaerobic ammonium oxidation effluent of high-nitrogen wastewater, but also removes organic matter and ammonia nitrogen from urban domestic sewage at the same time. Background technique [0002] In recent years, the phenomenon of eutrophication caused by excessive nitrogen and phosphorus concentrations in water bodies has ...
