Abstract
A high-efficiency membrane bioreactor comprising a hollow fiber membrane assembly is mainly composed of a biochemical aeration tank, the hollow fiber membrane assembly, a diversion water inlet region and a diversion partition plate. The high-efficiency membrane bioreactor is characterized in that a horizontal water inlet and a water outlet are arranged at the bottom of the biochemical aeration tank, a group of efficient turbulence aerators are mounted at the bottom of the biochemical aeration tank, the diversion partition plate is mounted at the bottom of the diversion water inlet region, and the hollow fiber membrane assembly provided with an aeration supporting tube is perpendicularly mounted in the diversion water inlet region. The efficient turbulence aerators mounted at the bottom of the biochemical aeration tank enable activated sludge in the tank, activated sludge flowing back to the diversion water inlet region, and sewage at the water inlet to be mixed sufficiently, and therefore damage to the hollow fiber membrane assembly by large particles in inflowing water and impact of inflowing water flow can be effectively reduced, and the segregational load of the hollow fiber membrane assembly is enormously lowered. Compared with the prior art, the high-efficiency membrane bioreactor is good in effluent water quality, high in pollution-resistant performance and excellent in anti-impact performance; and moreover, the occupied area of a system is small, and almost no excess sludge is discharged.
Description
Technical field
The utility model relates to the dynamical membrane bioreactor that a kind of hollow fiber film assembly consists of, and it belongs to water treating equipment.
Background technology
MBR (membrane bioreactor) refers to a kind of new waste disposal plant that membrane separation technique and bio-reactor in sewage disposal are combined and form.Existing MBR device, weak point is: one, need to cultivate a large amount of biological sludges and build settling bowl, so the equipment complexity is various, floor space is large, is difficult to construction and carries out, and has affected the development of water technology.Two, film is seriously polluted, due to the long-term filter activity mud mixed liquid of membrane module, pollutent is constantly at the film surface deposition, bacterium is constantly to the inner breeding of film, the meta-bolites of its generation is precipitated in fenestra, and then cause Pore Blocking, the flux of film is descended, membrane lifetime shortens, and the process operation expense increases.Three, membrane filtration weak effect, and water flux is low, so in MBR technique, the mould material kind affects its stain resistance consumingly, and the topmost approach that solves membrane pollution problem is to find resistant to pollution mould material or film is carried out modification.
The utility model content
The purpose of this utility model, be to provide a kind of tubular fibre membrane biological reaction treater, after the tubular fibre polyvinylidene difluoride (PVDF) membrane module that this bio-reactor utilization has a large flux of high strength of three-dimensional net structure carries out mud-water separation, directly be trapped in biological sludge in bio-reactor, and what see through film is high-quality water outlet, the anti-particulate matter of membrane module is wherein cleaned, and the flux conservation rate is high, therefore the utlity model has device simple, life-span is long, anti-fouling performance is high, the characteristics such as effluent quality excellence.
In order to achieve the above object, the utility model is realized by following proposal.The dynamical membrane bioreactor that a kind of hollow fiber film assembly consists of, it mainly is comprised of biochemical aeration tank, hollow fiber film assembly, water conservancy diversion inhalant region and diaphragm, it is characterized in that, be provided with horizontal water inflow mouth and water port bottom biochemical aeration tank, one group of efficient turbulent aerator is installed at the bottom of the pond, diaphragm is installed in water conservancy diversion inhalant region bottom, and in the water conservancy diversion inhalant region, at right angle setting has the hollow fiber film assembly of aeration supporting tube.The internal diameter that consists of the hollow fiber film thread of membrane module is 0.6-1.5mm, and the hole on face is the 3 D stereo network structure, and porosity is not less than 80%.
The utility model is compared with other technology, has following beneficial effect:
The utility model is selected the tubular fibre polyvinylidene difluoride (PVDF) film production membrane module of the large flux of high strength with three-dimensional net structure, effluent quality is good, and anti-fouling performance is high, and shock resistance is better than existing membrane module, and system's floor space is little, arranges hardly excess sludge.The utility model makes air-water keep indraft by the diaphragm in the water conservancy diversion inhalant region and the interaction of aeration supporting tube, and the strengthening fluid shearing force effectively delays film and pollutes, and has improved the steadiness of active sludge.In addition, the active sludge that efficient turbulent aerator in biochemical aeration tank makes active sludge in the pond, water conservancy diversion inhalant region reflux to return and the sewage of water-in fully mix, both can effectively reduce the macrobead in water inlet and the damage of water impact to membrane module of intaking, accelerate simultaneously the decomposition in advance of larger molecular organics, greatly reduce the segregational load of hollow-fibre membrane.
Description of drawings
In accompanying drawing, 1-biochemical aeration tank, 2-film head, the efficient turbulent aerator of 3-, 4-water conservancy diversion inhalant region, 5-hollow fiber film thread, 6-diaphragm, 7-aeration supporting tube.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, a kind of tubular fibre membrane biological reaction apparatus for treating sewage, mainly formed by biochemical aeration tank 1, water conservancy diversion inhalant region 4, hollow fiber film assembly, be provided with horizontal water inflow mouth and water port bottom biochemical aeration tank, one group of efficient disorderly gas device 3 is installed at the bottom of the pond, it can not only effectively guarantee air-water contact and dissolved oxygen concentration, and can efficiently keep the turbulent velocity of liquid, so that the active sludge in the pond and the solid in sewage are in suspended state.Diaphragm 6 is installed in water conservancy diversion inhalant region 4 bottoms, by the strengthening fluid shearing force, guarantees staggered the flowing of high speed of fluid, keeps the efficient operation of membrane module and the steadiness of active sludge.The interior installation of water conservancy diversion inhalant region 4 has the hollow fiber film assembly of aeration supporting tube 7.Under the acting in conjunction of diaphragm 6 and aeration supporting tube 7, make blowing gas stream and current form the concurrent that effectively prevents pollution of hollow fiber film, active sludge after membrane module is concentrated overflows water conservancy diversion inhalant region 4 with the stirring of air-water stream, is back to biochemical aeration tank 1.
