Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic ammonium oxidation biofilms, in particular to a culture and storage device based on anaerobic ammonium oxidation biofilms. Background Art

[0002] Anaerobic ammonium oxidation biofilm is a biofilm composed of a group of microorganisms that can carry out ammonia oxidation reactions in an environment without oxygen. This biofilm plays an important role in the treatment of wastewater and sewage. The microorganisms in the anaerobic ammonium oxidation biofilm use the symbiotic relationship between ammonia oxidizing bacteria and denitrifying bacteria to complete the removal of ammonia nitrogen from wastewater through their respective metabolic activities. Ammonia oxidizing bacteria convert ammonia nitrogen into nitrite, while denitrifying bacteria reduce nitrite to nitrogen gas. This process does not require oxygen and can therefore be carried out under anaerobic conditions. The formation of anaerobic ammonium oxidation biofilm requires a suitable biological carrier, usually a porous material such as a sponge-like polymer or porous ceramic. On this carrier, microorganisms can attach and form a biofilm. This biofilm has high activity and biological quality, which can improve the efficiency of ammonia oxidation reactions. Anaerobic ammonium oxidation biofilm technology has been widely used in the field of wastewater treatment. Compared with traditional aerated biological treatment methods, anaerobic ammonium oxidation biofilm technology has a higher ammonia oxidation rate and lower energy consumption. In addition, anaerobic ammonium oxidation biofilm technology can also remove ammonia nitrogen and organic matter at the same time, making wastewater treatment more efficient. When cultivating anaerobic ammonium oxidation biofilm, a storage device is required for cultivation, and the storage device is in an anaerobic state.

[0003] As shown in the application number: CN201610443248.4, the present invention relates to a rapid enrichment and cultivation device for anaerobic ammonia-oxidizing bacteria, and belongs to the technical field of enrichment and cultivation of anaerobic ammonia-oxidizing bacteria and treatment of high-concentration ammonia nitrogen wastewater in environmental engineering. The anaerobic membrane bioreactor and the sampling system of the present invention are the main parts. The bottom end of the outlet pipe (12) of the anaerobic membrane bioreactor is consolidated with the membrane assembly (7) through a three-way valve (8), and a filler (18) is provided inside the inner cylinder body (6). The sampling system is used to take out the biofilm sample and the suspension sample on the filler to reduce the influence of sampling on the operation of the reactor. By adding fillers to the anaerobic membrane bioreactor to form a biofilm, and utilizing the mechanical friction effect of the filler on the membrane filament, the membrane pollution is effectively slowed down while ensuring the efficient enrichment of anaerobic ammonia-oxidizing bacteria. The present invention has the characteristics of high volumetric load, good effluent quality, high degree of automation, and stable operation, which can effectively slow down the pollution process and is suitable for the enrichment and cultivation of anaerobic ammonia-oxidizing bacteria and the treatment of high-concentration ammonia nitrogen wastewater.

The number of the insertion rods 10 is the same as that of the insertion holes 3, and the insertion rod 10 is in snap connection with the insertion hole 3. Temperature controllers 11 are arranged on the left and right sides of the upper end of the sealing cover 9, and an air extraction pump 12 is arranged in the middle of the upper end of the sealing cover 9. An air outlet 13 is arranged at the upper end of the air extraction pump 12. Heating pipes 14 are installed at the left and right ends of the inner wall of the sealing cover 9, and an air extraction port 15 is installed in the middle of the inner wall of the sealing cover 9. The adsorption force between the suction cup 8 and the fixing plate 7 can position the inner box 4, effectively prevent the inner box 4 from shaking inside the cultivation and storage box 1, and avoid collisions of the inner box 4. The snap connection between the insertion rod 10 and the insertion hole 3 facilitates the assembly of the sealing cover 9 and the cultivation and storage box 1 and ensures the sealing performance between the two. The temperature controller 11 can adjust the temperature of the heating pipe 14, so as to adjust the temperature inside the cultivation and storage box 1 and provide a certain temperature environment for the cultivation of anaerobic ammonium oxidation biofilm.
