Abstract

The invention discloses a method for establishing a high-quality anaerobic ammonia oxidation biological membrane. The method comprises the following steps: designing anaerobic ammonia oxidation inoculated sludge; determining inoculated sludge particle size distribution; selecting or designing a carrier, which has a porous structure, wherein the particle size mean value serves as the carrier pore diameter; enabling an inoculation liquid to circularly penetrate through the porous carrier, and operating for 5-10 days to complete acquisition of initial biomass. The method has the advantages of stable and continuous operation. The initial biomass develops into colonies, and the high quality anaerobic ammonia oxidation biological membrane, which has the advantages of short formation time, high mechanical stability, high ecological stability and high abundance of target microorganisms, is obtained. Based on the characteristics of aggregation and growth of anaerobic ammonia oxidation microorganisms, a system is established by integrating biological membranes, the advantages of anaerobic ammonia oxidation aggregates and flocculent sludge are fully exerted, a high-quality biological membraneis established, and the method is simple, convenient and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of sewage biological treatment, in particular to a method for establishing a high-quality anaerobic ammonium oxidation biofilm. Background technique [0002] Anaerobic ammonium oxidation is a high-efficiency and energy-saving biological denitrification mode. It can realize the simultaneous removal of ammonia nitrogen and nitrite in water, and the final product is nitrogen without secondary pollution. Autotrophic anaerobic bacteria, the whole denitrification process does not require external carbon source inspection and aeration. Therefore, compared with the traditional nitrification and denitrification denitrification mode, the anammox process has obvious advantages. However, due to the nature of anaerobic autotrophy, the growth of anammox bacteria is very slow, and they are extremely sensitive to changes in the external environment, which makes it difficult to start the anammox process, and it is difficult...
