Problems solved by technology

However, the mechanical agitation fermenter is still widely used in the industry at present, because the airlift reactor in industrial application is particularly prone to coalescence during the rise of the bubbles, and the controllability of operating parameters is low. Equipment Generalizability will be limited

Abstract

The airlift reactor comprises an outer cylinder, a guide pipe is arranged in the outer cylinder, a sealing cover is arranged at a cylinder opening of the outer cylinder, a liquid outlet and a gas distributor are arranged in the sealing cover, the gas distributor is arranged at a lower end opening of the guide pipe, and the liquid outlet and the gas distributor are communicated with each other. A spiral plate is arranged in the guide pipe, and a liquid inlet is formed in the bottom of the outer cylinder. The airlift reactor for treating the soybean oil refining wastewater by the fermentative trichosporon is used for realizing treatment and resource utilization of the soybean oil refining wastewater and improving the wastewater treatment efficiency.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment equipment, and in particular relates to an air-lift reactor used for fermentative Trichosporon to treat refined soybean oil waste water. Background technique [0002] Refined soybean oil wastewater contains high concentrations of oil and organic matter, if it is discharged directly without treatment, it will cause water pollution. The domestic refined soybean oil wastewater treatment method generally adopts oil separation-coagulation air flotation-aerobic biological treatment, and the treated oil is landfilled after harmless treatment, and COD can meet the discharge standard. However, the above-mentioned process has high investment cost, large floor area, complex process, and only aims at removing oil and reducing COD in wastewater to treat refined soybean oil wastewater, wasting a large amount of oil and available organic matter in wastewater. Some microorganisms such as yeast, bac...
