Problems solved by technology

In order to ensure the cleanliness of the surface of the membrane filament, high-intensity air flow and water flow are required, which brings a huge amount of energy consumption for aeration, and frequent aeration will lead to excessive oxygenation of the water quality, which will lead to deterioration of the water quality. Adding other corresponding elimination processes greatly increases the operating cost of sewage treatment

Abstract

Disclosure of the present application The present application discloses a pulse aerator and a membrane assembly including the pulse aerator. The pulse aerator includes an aerator body, an aeration component and an air supply component. The aerator body has an aeration chamber opening downwards. The aeration component is arranged in the aeration chamber. The aeration assembly includes the air collecting hood and the air outlet. The opening of the air collecting hood faces the top of the aeration chamber and has a predetermined distance from the top of the aeration chamber. The air outlet is vertically inserted into the air collecting hood at a predetermined depth, and the top opening of the air outlet passes through the aerator body. The air supply assembly includes an air supply pipe arranged under the aeration chamber. The air supply pipe is provided with an air supply hole. The gas in the air supply pipe is discharged into the aeration chamber through the air supply hole, and gradually lowers the water level in the aeration chamber to the bottom opening of the aerator. Under the dual action of water pressure and air pressure, the gas is instantly discharged into the aeration device through the aerator to achieve high High-intensity aeration, so as to scrub the mud on the surface of the membrane unit.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pulse aerator and a membrane assembly including the pulse aerator. Background technique [0002] Membrane bioreactor technology is a new high-efficiency sewage treatment process that combines high-efficiency membrane separation technology with traditional activated sludge method. Membrane bioreactors use hollow fiber membranes to efficiently separate mud and water. At the same time, because of their effective interception, microorganisms with a long generation cycle can be retained to achieve deep purification of sewage. At the same time, nitrifying bacteria can fully reproduce in the system, and the nitrification effect is obvious. , to provide the possibility of deep phosphorus and nitrogen removal. [0003] However, at present, the MBR membrane system mainly uses perforated tube aeration, which uses the tiny holes distributed on the surface of the hollow fiber memb...
