Embodiment 1

[0025] Such as Figure 1 to Figure 2 As shown, the air-water balancer of the central source composite membrane bioreactor according to the present invention includes a frame housing 1, an air-water diversion plate groove 2, a single needle device 3, a multi-needle device 4, and an adjusting pinhole plate 5 And fixed connection seat 6, concrete structure and connection relation are:

[0026] The bottom of the frame housing 1 is placed in the L-shaped groove formed by the top four corners of the membrane module of the central source composite membrane bioreactor. The edge end of the flap is fixed to the inner edge of the frame housing 1 by welding or bolts. The single needle device 3 is a sharp long needle, and the single needle device 3 is irregularly arranged to fix the inner edge of the frame housing 1 and the air-water guide. On the folding plate of the baffle plate groove 2, the sharp needle head is facing downward, and the needle head is allowed to tilt at a certain angle...

Embodiment 2

[0032] The present embodiment is the application of the air-water balancer of the central source composite membrane bioreactor of the present invention in sewage treatment, comprising the following steps:

[0033] A domestic sewage treatment plant, the influent water volume is 1000m 3 / day, design main water quality: COD Cr 3 -N Cr 3 -N<5(8)mg / L, total phosphorus<0.5mg / L, PH=6~9.

[0034] Main treatment process: sewage collection→pretreatment→central source composite membrane bioreactor→disinfection→clean water pool→standard discharge or reuse.

[0035] There are 3 online dissolved oxygen meters installed in the central source composite membrane bioreactor. The 1# online dissolved oxygen meter detects the dissolved oxygen in the sewage at 300mm directly below the gas-water balancer, and the 2# online dissolved oxygen meter detects the 200mm directly above the gas-water balancer. The dissolved oxygen in the sewage, the 3# online dissolved oxygen meter detects the dissolved ox...

Embodiment 3

[0043] The present embodiment is the application of the air-water balancer of the central source composite membrane bioreactor of the present invention in sewage treatment, comprising the following steps:

[0044] The sewage treatment station of a hospital, the influent water volume is 500m 3 / day, design main water quality: COD Cr 3 -N8 (piece / L), PH=6~9. Since the municipal sewage pipe network has not been built near the hospital, the design discharge standard meets the first-level A standard of the "Pollutant Discharge Standard for Urban Sewage Treatment Plants" (GB 18918-2002) promulgated by the state, namely: COD Cr 3 -N3 (piece / L), PH=6~9.

[0045] Main treatment process: sewage→pretreatment→central source composite membrane bioreactor→disinfection→clean water pool→standard discharge.

[0046] There are 3 online dissolved oxygen meters installed in the central source composite membrane bioreactor. The 1# online dissolved oxygen meter detects the dissolved oxygen in th...

Abstract

A gas-water balancer for a central source composite membrane bioreactor is disclosed. The bottom of a frame shell of the gas-water balancer is disposed in L-shaped grooves formed by four corners of amembrane module of the central source composite membrane bioreactor; a gas-water flow-guiding deflector groove is composed of a plurality of continuous deflectors, and the edge of each deflector is fixed by welding or bolting to the inner edge of the frame shell; single-needle components are irregularly fixedly arranged at the inner edge of the frame shell and the deflectors of the gas-water flow-guiding deflector groove, and multi-needle components are fixedly disposed at adjusting rods of a needle pore adjusting plate; and four edges of the needle pore adjusting plate are fixedly connected with the frame shell, and a fixed connecting seat is fixedly connected with a central source generator of the central source composite membrane bioreactor via bolts. The gas-water balancer for the central source composite membrane bioreactor can improve air utilization rate and reduce energy consumption while ensuring the treatment effect of a conventional membrane bioreactor treatment process.

Description

technical field [0001] The invention relates to a sewage processor, in particular to an air-water balancer for a central source composite membrane bioreactor. Background technique [0002] At present, the MBR treatment process in sewage treatment technology is more and more widely used, and the relevant MBR treatment process types mainly include: MBR system, anaerobic MBR, A 2 O+MBR treatment device, composite CAS-MBR sewage treatment system, membrane aeration MBR device, ultrasonic MBR reactor, fixed bed MBR equipment, MBR comprehensive sewage treatment, fluidized bed MBR equipment, membrane material modified MBR Membrane bioreactor, double self-circulation integrated MBR reactor, facultative MBR integrated sewage treatment equipment, AMBR sewage treatment device, BMBR, CMBR, DMBR, EMBR, FMBR, etc. The general advantages of the above MBR treatment process are: Cr , BOD, and SS have good treatment effects, stable water output, and small footprint, but the common disadvanta...
