Embodiment 1

[0033] Such as figure 1 Shown is a schematic structural diagram of the anammox biofilm reactor of the present invention, including a reaction tank 7 and an inlet tank 1 . The lower part of the reaction pool 7 is provided with a water inlet. The water inlet tank 1 is connected to the water inlet of the reaction tank 7 through a water inlet pipe 8, and the water inlet pipe 8 is provided with a water inlet pump 2 and a water inlet valve 3. The water inlet valve 3 is preferably arranged at the position where the water inlet pipe 8 is connected to the water inlet. Five filter assemblies 6 are arranged in the reaction tank, and the filter assemblies include a support structure with a cavity and permeable water and non-woven fabrics covering the outer surface of the support structure. The top of each filter assembly 6 is connected to the water outlet pump 4 through an outlet pipe 9 , The outlet pipe 9 is provided with a vacuum pressure gauge 5. The outlet pipe 9 communicates with...

Abstract

The invention relates to the technical field of environmental protection and sewage treatment equipment, in particular to a novel anammox biomembrane reactor and a biological denitrifying method using the anammox biomembrane reactor. The anammox biomembrane reactor comprises a reaction tank and at least one filtering assembly inside the reaction tank, wherein the filtering assembly comprises a water-permeable supporting structure with a cavity, and non-woven fabric covering on the outer surface of the supporting structure; the tops of all filtering assemblies are connected with a water outlet pump through water outlet pipes; the water outlet pipes are communicated with the cavities of the all filtering assemblies; and a water inlet is formed at the lower part of the reaction tank. The anammox biomembrane reactor is simple in structure, high in denitrifying efficiency and effective in mass transfer enhancement.

Description

technical field [0001] The invention relates to the technical fields of environmental protection and sewage treatment equipment, in particular to a novel anaerobic ammonium oxidation biofilm reactor and a biological denitrification method thereof. 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 most widely used traditional nitrification-denitrification process consumes a lot of energy in the nitrification section, and the demand for carbon sources in the den...
