Description
Technical field
The utility model relates to technical field of sewage, and in particular to a kind of New type automatic cleaning formula plate film assembly.
Background technique
The exploitation of sanitary sewage has the efficient recycling and the sustainable development of resource of freshwater resources important
Research significance.At present for there are many processing schemes of sanitary sewage, the wherein tradition side of membrane bioreactor (MBR) membrane technology
Method all has the shortcomings that water quality is poor.There are two large problems for current general immersion type membrane component: film wire be easily broken off abrasion and
Fouling membrane is serious, therefore is researched and developed to New type automatic cleaning formula immersed type flat plate membrane component and be just particularly important.Its
In, Publication No. CN105461052A, CN103463988B, CN106745704A and CN101293701B are to having mentioned at sewage
The cleaning of reason efficiency and MBR module proposes technical solution.
Currently, the research in relation to control membrane fouling both at home and abroad is concentrated mainly on optimization of operating condition, membrane material improves, improves
Mud mixed liquid characteristic, improvement film surface hydrodynamic performance etc..In recent years, with Fluid Mechanics Computation (CFD) software and
The continuous development of flow field measurement technique receives many by improving film surface hydrodynamic performance come the method for decelerating membrane pollution
The concern of person.On the one hand, some scholars improve film surface hydrodynamic performance by way of introducing mechanical force.Li Bo etc. passes through
A kind of trapezoidal plate type membrane assembly (Authorization Notice No. CN101293701B) is gone out to the Curve guide impeller of plate film assembly vertical structure,
This kind of trapezoidal plate type membrane assembly can be improved film surface aeration flush efficiency, be conducive to mitigate fouling membrane.Some scholars also according to
Kelp spiral growth principle designs a kind of spiral membrane module, this kind of spiral membrane module has the fluid force better than plate film assembly
Learn performance, can effective decelerating membrane pollution, and improve membrane flux.Compared with classic flat-plate membrane module, the above novel membrane module
Loading density certainly will decrease.
Current cleaning way mainly has on-line cleaning and offline cleaning two ways, requires using chemical agent.Into
When row on-line cleaning and offline cleaning, corresponding MBR module cannot all be run, and will lead to entire MBR system water yield
Decline, frequent cleaning are even more the normal operation for the system that disturbs.The chemical agent that on-line cleaning adds can enter in reactor,
Microorganism is damaged.Membrane module is lifted out reaction tank to be cleaned offline, labor intensity is even more increased.There are also workers
Manual formula cleaning, it is even more time-consuming and laborious, so how to improve the contamination resistance of MBR module, reduce all kinds of cleanings either not
It is the forward position of research with cleaning.
Utility model content
The purpose of this utility model is to provide a kind of New type automatic cleaning formula plate film assemblies, it is intended to solve above-mentioned film wire
It is easily broken off abrasion and the serious technical problem of fouling membrane.
The utility model adopts the following technical solution: a kind of New type automatic cleaning formula plate film assembly, comprising: multiple intervals
Flat membrane component, the frame and automatic cleaning system for fixing flat membrane component being stacked.
The film that the flat membrane component uses is placed on the poly- inclined fluorine that 20min is impregnated in the ethanol solution of mass fraction 20%
Ethylene (PVDF) microfiltration membranes are made of, nominal pore size PVDF organic film material and polyethylene terephthalate (PET) substrate
It is 0.16 μm, the monolithic membrane of flat membrane component is having a size of 0.6m × 0.3m.
The lower part of flat membrane component is arranged in the automatic cleaning system, by power driven system, transmission system and cleaning system
Composition, power driven system are motor, and transmission system is the portion that all can be used for being driven with the matched chain of motor, rope or belt etc.
Part, the cleaning system include aeration tube, nozzle, aperture scraper and driving member, and cleaning system connects air blower, air blower connection
Aeration tube, aeration tube are equipped with multiple aperture scrapers with nozzle, and the both ends of aeration tube are equipped with driving member, and driving member is bearing
Or the component of gear, driving member are connected by transmission system with power driven system.
The aperture scraper is in the equally distributed n blade of aeration tube, n >=4, and blade is center clamp region, blade
Material is soft plastic, and multiple nozzles, nozzle diameter 1.2mm are arranged on blade.
The utility model has an advantageous effect in that due to the adoption of the above technical scheme, from improvement film surface hydrodynamic performance
Angle, under the premise of not reducing membrane module loading density and not reducing film effective area, pass through select stain resistance strong poly-
Vinylidene (PVDF) membrane material, since loading density is 50m2/ membrane module flux it is big, to the receiving load of pollutant
Greatly, flux decline is slow in operational process, produces the features such as water turbidity is low, and production water water, matter is stablized, and the cleaning frequency is long, overcomes biography
The problem that the anti-pollution for plate membrane of uniting is poor, the cleaning frequency is frequent.Cleaning system uses the aperture scraper with nozzle, and aperture scraper has
Conducive to the rising of bottom air bubble, while stirred reactor sludge, nozzle is installed on scraper, the spraying collaboration that nozzle generates is scraped
Knife, the more effective sludge removed on membrane module, prevents fouling membrane.
