After the output water from the absorption pool enters into the vibration film filtration device, the motor drives the eccentric block to rotate causing a base to swing and transmits the drive to the film component at the upper part through the main shaft, thereby leading the film component to swing continuously and discharging sludge in suspension instead of depositing at the film surface.
Description
Technical field
The present invention relates to a kind of absorption regeneration detachable membrane bioreactor that is used for water treatment.Be specifically related to the combination of adsorpting regenerating process and two kinds of process structures of vibration-type membrane filter appts.
Background technology
Membrane bioreactor is the biochemical water treatment system that the high performance membrane isolation technique combines with the active sludge biological reactor, is considered to have one of new and high technology of development potentiality in the 21 century water treatment field most.Compare with traditional sewage biochemical processing, membrane bioreactor has good effect of separating solid from liquid, biochemical efficiency and contaminant removal efficiency height, and the excess sludge productive rate is low, capacity of resisting impact load is strong; Advantages such as system can realize all that PLC concentrates automatic control, and moves and control flexibly, stablize, and management maintenance is simple and convenient.The membrane module of present applied detachable membrane bioreactor has the film case, and bio-reactor only is a simple pond of function, exist produce easily that film pollutes, cost is big, troublesome maintenance, to shortcomings such as ammonia nitrogen removal frank in the water are low.Yet film pollutes, and is to influence the key issue that the membrane bioreactor scale enlarges and applies.In general, film pollute that various particulates, colloidal particle or the solute macromole be meant in the material handling and film exist physical chemistry interaction or mechanical effect and in face, fenestra precipitation with accumulate, cause film surface pollution, membrane pore size to diminish or stop up, the permeable resistance of film increases, the phenomenon that membrane flux reduces and separation performance descends.The film pollution can cause membrane flux continue to reduce, influence simultaneously system steady running, energy consumption, film work-ing life and change frequency, be directly connected to the economy of membrane biological reactor process.Mainly containing control aeration rate, the subcritical flux of use constant, water outlet at intermittence etc. aspect the pollution of reduction film at present; Also utilize the method for cross-flow for detachable membrane bioreactor.But above method can not really solve the film pollution problems.
Summary of the invention
The objective of the invention is to solve the membrane pollution problem in the membrane bioreactor application, propose a kind of absorption regeneration detachable membrane bioreactor that is used for water treatment.
Technical scheme of the present invention is that biological processing unit is separated with membrane filter unit, and biological processing unit adopts adsorpting regenerating process, and membrane filter unit adopts a kind of vibration-type membrane filter appts, does not need the film case.The present invention had both had the advantage of adsorpting regenerating process, and the treatment effect that can solve the adsorpting regenerating process existence again hangs down and should not handle the problem of the more sewage of solvability organic pollutant content; Adopt the second pond in the vibration-type membrane filter appts replacement adsorpting regenerating process, the problem that both can avoid effluent quality to worsen can overcome film pollution problems in the membrane bioreactor application process again.
Principle of the present invention is: after the water outlet of adsorption tank enters membrane module on the membrane filter appts, adjustable frequency motor on the device drives eccentric block and rotates, cause the swing of base, the energy of rotation is delivered to the membrane module on device top again by central principal axis, causes that membrane module ceaselessly swings.This swing can make that film constantly vibrates in the assembly, produces sinusoidal shearing wave, makes mud in the water that needs to handle be in suspended state and discharges from the impurity exit, can not be deposited on the film surface, has also just eliminated the film pollution problems.And simultaneously, the clear water after the filtration then is drawn out of from device top rising pipe.
The absorption regeneration detachable membrane bioreactor that is used for water treatment, it is characterized in that: it comprises biological processing unit of being made up of water inlet pipe, adsorption tank, regenerated reactor and reflux pump and the membrane filter unit of being made up of membrane filter appts and suction pump, the combination of two kinds of process structures, membrane filter unit are connected between adsorption tank and the regenerated reactor; Biological processing unit adopts adsorpting regenerating process, and membrane filter unit adopts the vibration-type membrane filter appts of no film case.
The vibration-type membrane filter appts includes counterweight, generous plate, clamp mechanism, sludge out pipe, water inlet pipe, goes out clear water pipe, membrane module, elastic axis, motor, transmission shaft, eccentric block and support, it is characterized in that: the support inner bottom part has a generous plate, elastic axis is connected with generous plate center, and through vibroshock with contact; Be connected with clamp mechanism on the elastic axis, clamp mechanism and support are fixed; There is screw socket the elastic axis upper end, is connected with membrane module, establishes sludge out pipe in the elastic axis and stretches out frame bottom; The Yi Jiaochu of generous plate is connected with transmission shaft, and the transmission shaft top is connected with motor, and the below is connected with eccentric block; Be connected with counterweight on the generous plate; The membrane module top is connected with water inlet pipe and goes out the clear water pipe; Water inlet pipe is connected with adsorption tank, goes out the clear water pipe and is connected with suction pump.
Membrane module is fixed by bottom thread and main shaft top by axis, is with counterweight, lower end cover, shrouding, standard film part, upper sealing plate and upper end cover down from the bottom up successively, between the upper and lower end cap by a plurality of bolted.Lower end cover and following counterweight circle are also used a plurality of bolted; Middle shaft hollow surface is porose, and there is the clean water outlet of going out on the top, and water-in is stamped in upper sealing plate and upper end, and mud mouth is stamped in following shrouding and lower end, and mud mouth is communicated with sludge out pipe.
Membrane module is to be stacked to arrange by one or more standard film parts to form, and each standard film part is affixed by rivet by diaphragm, non-woven fabrics, stainless steel pallet, diaphragm, non-woven fabrics successively, and diaphragm can be microfiltration membrane, ultra-filtration membrane, nanofiltration membrane; Separate successively by interior ring and outer shroud between each standard film part.
The present invention has the following advantages and positively effect:
1, do not adopt the film case, utilize a kind of vibration-type membrane filter appts, can overcome film pollution problems in the membrane bioreactor application process, improve the processing power of film, prolong the work-ing life of film;
2, the advantage that has adsorpting regenerating process, and it is low and should not handle the problem of the more sewage of solvability organic pollutant content to solve treatment effect that adsorpting regenerating process exists;
3, the vibration-type membrane filter appts has replaced the second pond in the adsorpting regenerating process, has avoided mud generation denitrification in the second pond and sludge settling property is reduced and then runs off, worsens the problem of effluent quality from second pond;
