Abstract

The invention relates to the field of waste water, and in particular discloses a waste water treatment reactor and a process method for treating waste water. The wastewater treatment reactor is sequentially arranged as anaerobic pool, anoxic pool, fan-shaped anaerobic ammonium oxidation pool and aerobic pool along the flow direction of waste water, forming a "pre-ammonification / nitrosation-anammox (short-range) CANON) - aerobic treatment" combined process. The reactor and process method for treating wastewater have high wastewater treatment efficiency, good nitrogen and phosphorus removal effects, and easy control and adjustment of reaction conditions.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a waste water treatment reactor and a process method for treating waste water. Background technique [0002] Anaerobic ammonium oxidation (Anammox) is the reaction of nitrite (NO 2 - ) as the electron acceptor to convert ammonia (NH 4 + ) into nitrogen (N 2 ), accompanied by the fixation of CO with nitrite as electron donor 2 and produce nitrate (NO 3 - ) biological process. The microorganisms that perform this process are called Anaerobicammonium oxidation bacteria (AAOB). [0003] Biological turntable is a kind of biofilm sewage biological treatment technology, which is artificial reinforcement of sewage irrigation and land treatment. This treatment method makes microbes such as bacteria and fungi, protozoa and other micro-animals grow on the biological turntable filler carrier Breeding, the formation of film-like biological sludge - biofilm. [0004] Anaerobic am...
