Abstract

The invention discloses an AAO process water treatment equipment, which relates to the technical field of water treatment. It adopts the combination of A/A/0 process and ABR baffle reactor to solve the problem of high nitrogen and phosphorus content in the sewage treatment process of artificial wetlands in rural areas. Sewage treatment is difficult, the backlog of solid suspended matter reduces the service life of constructed wetlands, and the technical problems of low effluent quality. The present invention includes anaerobic compartment A, anaerobic compartment B, anaerobic compartment C, and anoxic compartment in series. , the aerobic compartment A, the aerobic compartment B and the sedimentation chamber, the compartments are separated by a wave-shaped baffle, and the bottom of the aerobic compartment A, the aerobic compartment B and the sedimentation chamber downstream area is provided with a tree Branch-shaped porous aeration head, the tail end of the aerobic compartment B is connected to the anoxic compartment through the pipeline, and the sedimentation chamber is connected to the anaerobic compartment A through the pipeline. , phosphorus effect and volume utilization.

Description

technical field [0001] The invention relates to the technical field of water treatment, and more specifically relates to an AAO process water treatment equipment. Background technique [0002] The AAO sewage treatment process consists of four treatment units: anaerobic pond-anoxic pond-aerobic pond-sedimentation pond. The sewage flows through each treatment unit in sequence, and the independent treatment units are nitrifying bacteria in sewage biological treatment. , denitrifying bacteria and phosphorus accumulating bacteria provide a better living environment, so that better simultaneous nitrogen and phosphorus removal effects can be obtained, and have been widely used in the construction of existing sewage treatment plants. With the development of social economy and the acceleration of urbanization, the increasingly tight land resources force the existing sewage treatment plants to shorten the treatment process as much as possible, save land, and minimize the impact of sew...
