Abstract

The invention discloses a tower-type bioreactor synchronously removing carbon, nitrogen and sulfur. The bioreactor comprises a reactor body. The reactor body is divided from bottom to top an anaerobic zone, an anoxic zone and an aerobic zone. A plurality of baffles which are vertically staggered are disposed in the anaerobic zone, the anoxic zone and the aerobic zone. The right side of the anaerobic zone is provided with a filling-material bed. Anaerobic ammonium-oxidizing granular sludge and autotrophic / heterotrophic denitrifying granular sludge are respectively added into the anaerobic zone and the anoxic zone. A shortcut nitrification light biological carrier is added into the aerobic zone and the aerobic zone is provided with a plurality of groups of aeration systems. The right side of the anoxic zone is communicated with the aerobic zone through gaps. According to the bioreactor, synchronous removal of the carbon, the nitrogen and the sulfur can be achieved in the single bioreactor. The bioreactor is compact in structure and can recover elemental sulfur resource.

Description

technical field [0001] The invention relates to a tower type bioreactor for synchronously removing carbon, nitrogen and sulfur. Background technique [0002] With the continuous development of social economy, a large amount of complex wastewater rich in organic matter, ammonia nitrogen and sulfide, such as chemical production wastewater, agricultural product processing wastewater, anaerobic digestion solution, etc., is discharged into natural water bodies, causing very serious water pollution problems. [0003] The traditional biological treatment technology of wastewater containing organic matter, ammonia nitrogen and sulfide is mainly a multi-step combination process. Organic matter in wastewater is mainly removed through anaerobic digestion and aerobic activated sludge process; ammonia nitrogen pollutants are mainly removed through biological methods, and conventional biological treatment methods are mainly nitrification-denitrification processes; traditional treatment me...
