Anaerobic ammonia oxidation biofilm process and device for enhancing biological denitrification

Abstract

The invention discloses an anaerobic ammonia oxidation biofilm process and device for enhancing biological denitrification, and the device comprises an SBR, the SBR comprises a device body, an illumination assembly is arranged on the outer side of the device body, an anaerobic ammonia oxidation biofilm denitrification system is arranged in the device body, the anaerobic ammonia oxidation biofilm denitrification system comprises a filler frame, and carbon cloth is fixed in the filler frame, the carbon cloth and the illumination assembly are correspondingly arranged, and a stirring assembly is arranged in the middle of the filler frame in a penetrating manner. According to the device, rapid starting of the anaerobic ammonia oxidation biofilm system is achieved through the photothermal effect, ion signal conduction of microorganisms is promoted through photostimulation, energy consumption needed by heating is reduced, and the denitrification efficiency of the system is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anaerobic ammonium oxidation biofilm process and device for strengthening biological denitrification. Background technique [0002] In recent years, excessive discharge of a large amount of nitrogen-containing wastewater has caused eutrophication of water bodies, which has caused great harm to the aquatic ecological environment and drinking water safety. Due to its high economic benefits, biological denitrification is the most commonly used technology for denitrification of sewage. At present, the nitrification and denitrification process is generally used in sewage treatment plants, but the process is long, consumes a lot of oxygen, requires additional carbon sources, and has high operating costs. Therefore, anaerobic ammox technology, which can save carbon and energy and can efficiently remove nitrogen, is a hot spot in the current research on nitrogen removal. Ho...

Problems solved by technology

However, the disadvantages of ANAMMOX technology, such as high reaction temperature, slow microbial growth, and long start-up time, limit its application.

Although the coupling of anammox and biofilm can be used to promote microbial enrichment through the formation of anammox biofilm process, the influence of temperature is still one of the main limiting factors for its application, especially in areas with low temperatures. To achieve effective application
