Abstract

The invention discloses a pure membrane MBBR coupled carbon capture autotrophic nitrogen removal system and a use method thereof. The autotrophic nitrogen removal system comprises a carbon source capturing module, a carbon source recovery module and a methane power generation module. The carbon source capturing module comprises a contact tank and a stabilization tank. The carbon source recovery module comprises a sedimentation tank, the methane power generation module comprises an anaerobic fermentation tank and a methane collector, and the bottoms of the contact tank and the stabilization tank are respectively provided with an aeration device. and the bottoms of the contact tank and the stabilization tank are respectively provided with an aeration device. The autotrophic nitrogen removal system further comprises a first-stage anoxic MBBR module, a first-stage aerobic MBBR module and an efficient separation module which are arranged in series. The contact tank is communicated with the primary anoxic MBBR module through the sedimentation tank, and the sedimentation tank is respectively communicated with the fermentation tank and the stabilization tank. Granular COD and colloidal COD in sewage are captured by the carbon source capturing module and are fermented by the anaerobic fermentation tank to generate methane, so that the COD in a water body is removed, the methane is generated to be used for power generation of a power plant, energy circulation self-sufficiency is realized, and the environment-friendly and energy-saving effects of a denitrification system are improved.

Description

technical field [0001] The invention relates to an autotrophic denitrification system coupled with pure membrane MBBR for carbon capture and a use method thereof, belonging to the technical field of sewage treatment. Background technique [0002] Sewage refers to the water that loses its original function after being polluted and discharged in human life and production activities. At present, domestic water pollution is mostly water eutrophication caused by nitrogen and phosphorus pollution. Due to the complex exchange of materials and energy between organisms and water, organisms and organisms in nature, a dynamic balance relationship is maintained in terms of quantity. However, as the water polluted by nitrogen and phosphorus is discharged, it leads to eutrophication of the water body, and some beneficial aquatic organisms die in large numbers, while some sewage-tolerant organisms, especially algae, begin to reproduce in large numbers, consume oxygen in the water, and caus...
