Problems solved by technology

At present, the aerators used at the bottom of the membrane modules are mainly perforated tubes. The perforated tubes can achieve the effect of aeration, stirring and oxygenation, but there are the following deficiencies: First, the air distribution is uneven, which will cause severe scouring of some membrane modules and severe damage to some membrane modules. Insufficient flushing of the components, causing surface clogging of some membrane components
Secondly, it is easy to block during intermittent aeration

Embodiment Construction

[0028] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0029] An MBR high-efficiency and energy-saving aeration device is composed of two parallel intake main pipes and a set of branch pipes 2 . The intake main pipe is composed of a plurality of intake main unit sections 1 end-to-end plugged together. One end of each intake main unit section is formed with a socket 3 and the other end is formed with a socket 4 . The air intake main pipe has a plurality of gas distribution ports 9, and each air distribution port is shaped on the outer periphery of a socket 10, and the two ends of the branch pipe are all formed with a plug joint 5 inserted between the two air intake main pipes, and the side walls of the branch pipe are evenly distributed. There are vent holes 6.

Abstract

The invention relates to an MBR (membrane bioreactor) efficient energy-saving aerating apparatus, which is characterized by being composed of two parallel main intake pipes and a group of branch pipes. The main intake pipe is provided with a plurality of gas distribution ports, periphery of each gas distribution port is provided with a plugging groove, two ends of each branch pipe respectively are provided with a connecting plug plugged between the two main intake pipes, and sidewall of each branch pipe is provided with evenly distributed vent holes. The MBR efficient energy-saving aerating apparatus is scientific and rational in structure design, thus, installation flexibility of the aerating apparatus is increased greatly, blockage of vent holes is avoided, moreover, aeration uniformity can be realized better, gas utilization rate is improved, aeration rate is lowered remarkably, and operation cost is reduced.

Description

technical field [0001] The invention relates to an aeration device, in particular to an MBR high-efficiency energy-saving aeration device. Background technique [0002] MBR (Membrane Bio-Reactor, Membrane Bioreactor) is a new type of wastewater treatment system that organically combines membrane separation technology and biological treatment technology. In the existing MBR system, the aeration system is the key link of the whole wastewater treatment system and also the unit with the highest energy consumption. The main functions of aeration include: firstly, to continuously flush the surface of the membrane module to prevent the surface of the membrane module from clogging; secondly, to stir the muddy water entering the membrane module area (to prevent sludge from settling); finally, to increase the amount of water dissolved in the water Oxygen (to prevent anaerobic conditions in sewage) and maintain the activity of sludge. At present, the aerators used at the bottom of th...
