Description
Technical field
The utility model belongs to technical field of sewage, specifically, relates to the ultrasonic MBR system of a kind of self-stip.
Background technology
The suggestion that develops rapidly of membrane technique has been brought great effect to various fields, particularly be applied to the sewage treatment process aspect, membrane bioreactor has merged the biological degradation function of traditional biologic treating technique and the high efficiency separation function of membrane separation technique, have the significant advantages such as, stable effluent quality high to contaminant removal efficiency in sewage, convenient operation and management, floor space be few, application prospect is boundless.
But membrane pollution problem but usually can cause working cost to increase, and cleans complexity, and the film pollution causes due to pollutent in sewage to a great extent, and when pollutent is that water miscible macromole is, the solute concentration on film surface significantly increases the formation gel coat; When pollutent is the insoluble material, the solute concentration on film surface increases rapidly and surpasses its solubleness and form layer of scale; The adhesion layer on film surface may be that adsorption layer or the water-soluble macromolecule of water-soluble polymer received sterically hindered in fenestra, the surface of the water-soluble macromolecules such as protein in fenestra is adsorbed, and insoluble material separating out in fenestra etc. produces Pore Blocking, if MBR film sludge loading is too high, not only can not guarantee the clearance of pollutent, on the contrary also can promote and aggravate the pollution of film, so film must be cleaned timely.
Cleaning technique commonly used: physical cleaning, outer dipping matting and matting, the purging method that wherein physical cleaning refers to manually, any form chemical agent is not used in mechanical cleaning and clear water cleaning etc.And the physical cleaning required equipment is simple, but cleaning performance is limited, can not thoroughly remove film and pollute, can only be as a kind of simple maintenance service.
Wherein adopt outer dipping matting, need certain kit, as crane, if and there is no crane, need separately membrane module to be pulled and cleaned, because the film surface has part mud, while pulling, membrane module can be very heavy, for preventing that damaging connecting member for membrane needs SC, particularly three above diaphragms on chip need 2 people to operate just and can complete, and as adopted the crane cleaning performance, can not be very obvious, and the mud that is attached to the film surface can't wash fully, so clean both labor intensive, and clean not thorough.
And the chemical cleaning method principle is to allow its medicament fully contact with the film internal surface from an end of film flows to the continuous circulation process of the other end, kill also oxidation and grow the microorganism on face, make again the residual body of microorganism and solution discharge from film is inner simultaneously, externally flood mutually matting, it has carried out no small improvement, many manpowers and resource have been saved, but need the operation of halt system while adopting this method to be cleaned film, independent is cleaned membrane module, and repeat to close and start main equipment, can reduce the work-ing life of equipment.
Aeration is a kind of means that air is contacted strongly with water, and its purpose is airborne oxygen is dissolved in the water, or unwanted gas and volatile matter in water are banished in air.In other words, it is a kind of means that promote exchange of substance between gas and liquid.The effect of aeration, except delivering oxygen in water, also have the effect of accelerating in water, volatilizable material is taken the water surface out of.Most of organism often has volatility, although some organism volatility is very low, still needs to carry out aeration and is processed.
MLSS(mixed liquor suspended solid, MLSS concentration in the MBR membrane bioreactor adopted in sewage disposal now) very high, oxygen-consumption is higher than traditional biological treatment, and only for the MBR membrane bioreactor, be provided with a small amount of aerating apparatus in existing sewage disposal, make the dissolved oxygen amount in water often can not meet the consumption of MBR membrane bioreactor, cause can not reaching standard by the sewage after the MBR Membrane Bioreactor for Wastewater Treatment.
The prior art shortcoming: it is slow that film pollutes cleaning speed, cleans not thorough, can not the limit cleaning, the processing of sewage is carried out on limit, MBR membrane bioreactor oxygen-consumption is large, and existing aerating apparatus can not dissolve abundant oxygen in water, can not meet the consumption of MBR membrane bioreactor to oxygen.
Summary of the invention
For solving above technical problem, it is a kind of fast to film pollution cleaning speed that the purpose of this utility model is to provide, clean thoroughly, cost-saving, can clean on limit, sewage disposal is carried out on limit, can also meet the consumption of MBR membrane bioreactor to oxygen, and can improve the ultrasonic MBR system of self-stip of wastewater treatment efficiency.
The utility model purpose is achieved in that the ultrasonic MBR system of a kind of self-stip, its key is: comprise water collecting basin, this water collecting basin is divided into MBR membrane cisterna and two ponds of biochemical aeration tank by dividing plate, described dividing plate is provided with valve, at the bottom of the pond of described biochemical aeration tank and MBR membrane cisterna, is communicated with aerating apparatus; Described MBR membrane cisterna comprises the MBR membrane bioreactor, described MBR membrane bioreactor is comprised of MBR film frame and the MBR membrane module be arranged on MBR film frame, be fixed with at least one ultrasonic transducer on described MBR film frame, this ultrasonic transducer is connected with ultrasonic generator by cable.
Adopt said structure, utilize ultrasonic wave to cause violent turbulent flow, air pocket and vibrations in water and reach and remove the purpose that film pollutes, cleaning speed is fast, effective, can clean on limit, and sewage disposal is carried out on limit; And biochemical aeration tank first carries out Air Exposure to sewage, increase the dissolved oxygen amount of sewage, and except volatile organic compound in decontaminated water, then by valve, the sewage in biochemical aeration tank being entered to MBR membrane cisterna limit and carry out blast aeration, is carried out a biological disposal upon and membrane filtration in limit, further increased dissolved oxygen amount, improve biological treatment efficiency, improved the speed that the MBR film is processed, saved the treatment time of sewage.
Above-mentioned MBR film frame is rectangular parallelepiped framework or square framework.Adopt said structure, cube frame formula MBR film frame, the installation of convenience for ultrasonic transverter, have larger space for Ultrasonic Radiation, reduced echo to hyperacoustic impact.
