Description
Technical field
The present invention relates to water treatment facilities, be specifically related to the flat ceramic membrane module of a kind of rotatable swing.
Background technology
Earthenware slab membrane bioreactor is as a kind of new and effective sewage disposal technology, it has also become treatment technology indispensable in sanitary sewage, industrial wastewater or even extreme environment wastewater treatment.
Traditional wastewater treatment technology, divides by degree for the treatment of, can be divided into one-level, two grades and tertiary treatment.
Coagulation, is the solid pollution material of suspended state in main removal sewage, and physical treatment process major part can be only done the requirement of coagulation.Through the sewage of coagulation, BOD generally can remove about 30%, does not reach discharge standard.Coagulation belongs to the pretreatment of two stage treatment.Two stage treatment, is the organic pollution materials (BOD, COD material) of colloid and dissolved state in main removal sewage, and clearance, up to more than 90%, makes organic pollution reach discharge standard.Tertiary treatment, processes the Organic substance of difficult degradation, nitrogen and phosphorus etc. further and can result in the soluble inorganic matter etc. of body eutrophication.Main method has biological carbon and phosphorous removal method, coagulant sedimentation, sand filtration method, active carbon adsorption, ion exchange and electric osmose analytic process etc..Traditional handicraft suffers from the drawback that 1. COD oxidation and nitrated power consumption are huge, and floor space is big, and investment cost is high;2. denitrification is both needed to consume COD with the biogenic accumulation of phosphorus;3. surplus sludge volume is big;4. power consumption causes great amount of carbon dioxide to discharge, and enters air.
Applying increasing ceramic membrane bioreactor (CMBR) in current membrane bioreactor, CMBR has following main feature: intensity is high, and water flux is big, and the life-span is long;Treatment effeciency is high, effluent quality is good;Facility compact, floor space are little;Specific energy consumption is low, and operation expense is low;Easy realization automatically controls, operational management is simple.External Stackable type is adopted to increase disposal ability or mobile very convenient.But owing to ceramic membrane diaphragm there is problems in that 1. lamina membranacea is fixed in use, the fouling product that its membrane surface gathers can progressively increase.Although inoranic membrane contamination resistance improves a lot than organic membrane, but can room for promotion still very big, if pottery lamina membranacea can swing and rotate in certain angle when using, can greatly improve the contamination resistance of film. 2. film maintains static, pulsed gas water backwash can be repeatedly subjected in use, it is impossible to release stress. film can produce fatigue rupture, time length, film is easily generated fracture at folder residence and causes system crash, it is impossible to work.
Summary of the invention
The present invention is directed to problem existing in above-mentioned prior art, propose one and be furnished with gas and water automatic backwash, and bubble washes away film surface, carries out system automated cleaning, ensure diaphragm Effec-tive Function, can reinforced film antipollution effect, the flat ceramic membrane module of rotatable swing.
The technical problem to be solved in the present invention is adopted the technical scheme that: the flat ceramic membrane module of described rotatable swing includes combination housing, the board-like ceramic membrane filter assembly of some layers of hollow being disposed in combination housing up and down combines the aerator of bottom in housing with being arranged on, described hollow board-like ceramic membrane filter assembly is formed by some rows board-like ceramic film filtering element of spaced hollow and water collection sheet, the board-like ceramic film filtering element of described hollow is made up of the board-like ceramic diaphragm of hollow and the grip block being connected with hollow board-like ceramic diaphragm two ends sealing, described right-hand member grip block is fixedly installed axostylus axostyle, left end grip block is fixedly installed the axle sleeve with apopore, described axostylus axostyle matches with the circular hole activity on right-hand member water collection sheet, the circular hole activity of described axle sleeve and left end water collection sheet matches.
The board-like ceramic film filtering element of described hollow, with axostylus axostyle and axle sleeve for rotating shaft, can make the board-like ceramic diaphragm of hollow swing around the shaft under aeration pressure effect.
The board-like ceramic film filtering element of described hollow can be vertically set between water collection sheet;Also can be arranged between water collection sheet by inclined shape (1-15 ° of inclination angle).
Described aerator includes the aeration tube being crisscross arranged that takes the shape of the letter U, and described aeration tube is arranged at intervals with the solarization air cap of opening upwards, and described solarization air cap centerline hole is staggered offset from perpendicular 30 ° to the left or to the right.
Heretofore described waste water penetrates in intermediate throughholes by the micropore on diaphragm under certain pressure effect, except communicating with apopore except the intermediate throughholes having a row one end due to the multiple rows of intermediate throughholes on the board-like ceramic film filtering element of hollow, the whole held plate of other intermediate throughholes on this row is closed, thus is flowed into the clear water in intermediate throughholes and can only flow in collect cavity more externally discharge or other uses water through apopore.
The board-like ceramic filter assembly of hollow of the present invention can efficiently intercept, and can reach good filter effect.Simultaneously because hollow board-like ceramic filter assembly bottom is provided with aerator, the forward and reverse gas of pulse can be provided just to rinse pressure in interval, make filtration membrane swing with axostylus axostyle for initial point under the active force of air pressure and current when not using other energy, form shearing force and effectively reduce water pollutant in membrane surface deposition, and pulses generation different size gas forms void effect and washes away under the drive of current and take away.It can not only carry out system automated cleaning, it is ensured that filtration membrane Effec-tive Function and also treatment effeciency can be improved.
