Abstract

An apparatus and operation method for quickly forming anammox particles using a quorum sensing mechanism are related to the field of wastewater treatment. The invention is directed to an apparatus and operation method for quickly forming particulate sludge via anammox. The apparatus comprises a body reactor, a signal molecular generator, a spherical thin-shell rotary cover, a spherical screen, a manual rotating switch, a ball valve I, a ball valve II, a heating tape, and a temperature control probe. The signal molecular generator is added into the body reactor, signal molecules diffuse in the body reactor so that anammox flocculating sludge quickly forms particulate sludge, and the activity of anammox bacteria is significantly improved while the particulate sludge is formed. The method for implementation according to the invention is simple, has significant effect, is widely applicable to anammox sludge granulation and is effective in improving practical application of anammox process.

Description

technical field [0001] The invention relates to a device and an operation method for rapidly forming anaerobic ammonium oxidation granular sludge, belonging to the field of sewage biological treatment. Background technique [0002] With the increasing development of sewage treatment technology, new treatment processes have gradually become a research hotspot. As an ultra-efficient denitrification technology, anaerobic ammonium oxidation has attracted the attention of researchers. [0003] Anaerobic Ammonium Oxidation (Anaerobic Ammonium Oxidation, referred to as Anaerobic Ammonium Oxidation) is a biological denitrification reaction that uses ammonia as an electron donor to reduce nitrite to nitrogen. For ammonia oxidizing bacteria, the reaction equation is: [0004] NH 4 + +1.32NO 2 - +0.066HCO 3 - +0.13H + →1.02N 2 - +0.26NO 3 - +0.066CH 2 o 0.5 N 0.15 +2.03H 2 o [0005] Compared with the traditional nitrification-denitrification denitrification process, ...
