Abstract

The invention provides a method for quickly starting anaerobic ammonium oxidation in an upflow packed bed reactor. An upflow packed bed is taken as a reactor; a reaction zone and a precipitation zone are arranged in the reactor; a suspended filler which has a high specific surface area and density close to that of water and is difficult to block is selected as a reaction filler; activated sludge in a membrane bioreactor (MBR) tank in a process for treating anaerobic ammonium oxidation sludge and refuse landfill percolate is subjected to mixed inoculation; and the temperature of the reaction zone is controlled to be 32+ / -1 DEG C by a self-temperature control heating zone with a temperature control system. The suspended filler is added, so that flocculent sludge is retained in the reactor, biomass in the reactor is ensured, and an anaerobic ammonium oxidation process is quickly started; and the activated sludge in the MBR tank in the process for treating the anaerobic ammonium oxidation sludge and the refuse landfill percolate is subjected to mixed inoculation, so that the acclimation of the activated sludge in the MBR tank is promoted, acclimation time is shortened, and the starting speed is increased.

Description

technical field [0001] The invention relates to a method for rapidly starting anaerobic ammonium oxidation in an upflow packed bed reactor, and belongs to the technical field of rapidly starting anaerobic ammonium oxidation. Background technique [0002] With the development of industry and agriculture and the improvement of people's living standards, nitrogen pollution has become increasingly serious and has become one of the main factors of water environment pollution. Many countries have increasingly stringent requirements for ammonia nitrogen and total nitrogen in wastewater discharge standards. Biological denitrification has attracted the attention of researchers from various countries due to its advantages of low operating investment costs and small secondary pollution. However, the traditional nitrification-denitrification process consumes a lot of energy in the nitrification section, and the demand for carbon sources in the denitrification section is high. At presen...
