Abstract

The invention relates to a carbon and nitrogen removal system based on a moving bed biomembrane reactor. The carbon and nitrogen removal system based on a moving bed biomembrane reactor has the advantages of high reliability, simultaneous implementation of carbon removal and nitrogen removal, and good carbon and nitrogen removal effects. The system comprises an anaerobic tower, an aerobic tower, a shortcut nitrification tower and an anaerobic ammoxidation tower; a first filler is arranged in the anaerobic tower, a second filler is arranged in the aerobic tower, a third filler is arranged in the shortcut nitrification tower, and a fourth filler is arranged in the anaerobic ammoxidation tower; and a water inlet tank is connected with the water inlet of the anaerobic tower, the water outlet of the anaerobic tower is connected with the water inlet of the aerobic tower, the water outlet of the aerobic tower is connected with an intermediate water tank, the intermediate water tank is connected with the water inlet of the shortcut nitrification tower, the water outlet of the shortcut nitrification tower is connected with the water inlet of the anaerobic ammoxidation tower, and the water outlet of the anaerobic ammoxidation tower is connected with a discharge device.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a carbon removal and nitrogen removal system based on a moving bed biofilm reactor. Background technique [0002] With the rapid development of my country's industry, the organic wastewater containing carbon and nitrogen is increasing year by year. Therefore, sewage treatment is urgent. However, most of the prior art adopts the pool-type structure process, which occupies a large area, requires high civil construction costs, requires a large area for aeration, consumes a lot of power, complex structures, and troublesome maintenance and management. The filler in the pool structure is not in sufficient contact with the wastewater, and the removal effect is not good. Because of the structure, only one kind of microorganism can exist, so carbon removal and nitrogen removal cannot be carried out at the same time. In addition, the existing denitrification technology generally undergoes nit...
