Description
Technical field
The utility model relates to the MBR film group device that utilizes hollow fiber filter membrane to dispose of sewage, specifically, but the MBR membrane bioreactor of the on-line cleaning that the present invention relates to use in a kind of WWT, the middle water reuse in fields such as environmental protection, the energy, chemical industry.
Background technology
Membrane bioreactor combination process (Membrane Bioreactor; MBR) technology is to utilize biological respinse to combine with membrane separation technique; Utilize film to substitute conventional gravitational settling solid-liquid separation and obtain water outlet, and can change reaction process and the sewage water treatment method that improves reaction efficiency as separating medium.Film group device is a basic unit for treating water that is assembled into by membrane module, distribution device, captation, framework etc., places biological reaction tank, carries out the device of solid-liquid separation.MBR is a kind of novel sewage disposal technology, substitutes second pond with membrane sepn, produces water quality stabilizing, becomes one of focus of field of environment engineering research.
Present MBR technology mainly is divided into two kinds; A kind of is submerged membrane bio-reactor (submerged membrane bioreactor); Refer to that membrane module is immersed in the biological reaction tank, pollutent carries out biochemical reaction at biological reaction tank, utilizes film to carry out the equipment or the system of solid-liquid separation; Can adopt negative pressure to produce water, hydrostaticpressure also capable of using is from miscarrying water; Another kind is external membrane bioreactor (recirculated membrane bioreactor); Refer to that membrane module and biological reaction tank are arranged apart; Active sludge intermixture in the biological reaction tank pumps into the system that membrane module carries out solid-liquid separation, and the spissated mud mixture of this system is back to biological reaction tank and forms circulation.
Membrane bioreactor sewage treatment has the separation efficiency height; Characteristics such as activated sludge concentration is high, surplus sludge volume is few, and the residence time of the interior nitrobacteria of bio-reactor is long also can realize separating fully of hydraulic detention time (HRT) and mud age (SRT) simultaneously; Film separation unit does not receive the influence of factors such as sludge bulking; Make operation control flexible more, stable, be easy to realize automatic control, convenient operation and management.At aspects such as WWT, middle water reuses, obtain increasingly extensive application.
But no matter be submerged membrane assembly or external membrane assembly, in operational process, certain problem arranged all.For the submerged membrane assembly; Cleaning after assembly pollutes; Need hanging device lifting film group device outside the membrane biological reaction pond, wash, need add service sink; Also have certain way to solve the problem of cleaning for the fixed Sewage Plant, just very inconvenient for the cleaning of mobile integrated MBR film group device equipment.For the external membrane assembly, need the sewage of biochemical reaction be pumped into and carry out dense water cycle in the membrane module, because the sewage turbidity is high, can only adopt inner pressed tubular membrane component and big flow high lift pump to increase dense water circulating speed, stifled with the quick dirt that prevents film.This external membrane assembly operating energy consumption is higher than submerged membrane assembly operating energy consumption far away.
Summary of the invention
The purpose of the utility model is the shortcoming that overcomes or improve prior art, and a kind of MBR film group device that can on-line cleaning is provided, and need not lifting during cleaning, moves film group device, has simultaneously than immersion and the lower operation energy consumption of external placed type film group device.
The utility model comprises: membrane module container, but its bottom and the water-in and the water outlet of auto-switch are arranged respectively above the side; Curtain type film assembly or pencil membrane module are built in the membrane module container; The film group device open upper end is higher than membrane biological reaction pond liquid level, and the film group device bottom is provided with aerating apparatus, and medial surface is provided with elution device; Simultaneously, the membrane module container also is provided with blowdown apparatus and cleans chemicals dosing plant.
But the MBR film group device of described a kind of on-line cleaning is characterized in that membrane module need not lifting, moving film assembly when cleaning.
The MBR film group device of the utility model, container water-in and water outlet are opened when operation, and film group device communicates with the membrane biological reaction pond, and sewage gets into the MBR film group device, produces water pump operation; When membrane module cleans; Close MBR film group device water-in and water outlet; Membrane module cleans in the container of a sealing, need not lifting, moves, and keeps the sludge activity in membrane biological reaction pond; Be applied in the WWT environment that can not move, lift by crane film group device, be particularly suitable for mobile integrated MBR waste disposal plant.
