Problems solved by technology
Of course, while MBR has many advantages, it also has certain disadvantages: ① Membrane fouling is relatively fast ② High investment cost
[0007] 2. In order to achieve a certain flushing effect, the air volume consumed is large and the energy consumption is relatively high;
[0008] 3. There is a wide range of scrubbing dead angles on the surface of the membrane, and the air nozzle cannot aim at the clogged membrane surface for directional scrubbing, and the actual cleaning effect is very poor

Embodiment Construction
[0023] In order to understand the above-mentioned purpose, features and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with specific embodiments.
[0024] like figure 1 The flat film scrubbing device shown includes an air-water confluence pipe 2 and a nozzle 4. The air-water confluence pipe 2 is evenly distributed with holes 21 with a diameter of 0.5-2 mm, and the distance between the centers of adjacent holes 21 is 50-100 mm. , each channel 21 is provided with a connecting pipe 3 connected by a straight pipe 31 and an elbow 32, the straight pipe 3 is connected with the gas-water confluence pipe 2, and the nozzle 4 is composed of an upper duckbill 41, a lower duckbill 42 and The duckbill structure formed by the connecting port 43 has a crack formed between the upper duckbill 41 and the lower duckbill 42 , and the connecting port 43 is hingedly connected with the elbow 32 . In the non-working sta...

Abstract
The invention belongs to the technical field of flat sheet membrane cleaning, and particularly relates to a flat sheet membrane scrubbing device which comprises a gas-water converging pipe and a nozzle; a hole passage is formed in the gas-water converging pipe, and is provided with a connecting pipe; the connecting pipe is formed by connecting a straight pipe and an elbow; the straight pipe is connected with the gas-water converging pipe; and the elbow is connected with the nozzle. The flat sheet membrane scrubbing device provided by the invention can realize automatic regulation of a scrubbing direction by adopting a cleaning mode with gas and water combined scrubbing so as to directionally scrub a blocked membrane surface region with a better scrubbing effect.
Description
technical field [0001] The invention belongs to the technical field of flat film cleaning, and in particular relates to a flat film scrubbing device. Background technique [0002] Membrane bioreactor (MBR) is a kind of advanced sewage treatment technology that has gradually emerged in recent years. Because of its many advantages such as short process flow, good treatment effect, small footprint, and high microbial concentration, it is developing rapidly in practical engineering. stage. Of course, while MBR has many advantages, it also has certain disadvantages: ①Membrane fouling is relatively fast; ②The investment cost is high. In particular, membrane fouling has become an urgent problem that limits its rapid popularization. [0003] Membrane fouling refers to the adsorption and deposition of particles, colloidal particles or solute macromolecules in water on the membrane surface or in the membrane pores caused by physical, chemical or mechanical interaction with the membr...
