Description
[technical field]
The utility model relates to the water conditioning technical field, specifically a kind of immersion jet membrane bioreactor.
[background technology]
At sewage treatment area, membrane bioreactor is a kind of new type water treatment technology that is combined by biological processing unit and film separation unit.And in the multiple film bioreactor technology, the solid-liquid separating type membrane bioreactor is that a widely class is goed deep in research the most in sewage treatment industry.
In traditional biological wastewater treatment technology, mud-water separation is finished by action of gravity in second pond, and its separation efficiency depends on the settling property of active sludge, and settleability is better, and mud-water separation efficient is higher.And the settleability of mud depends on the operation conditions of aeration tank, improves the strictly operational condition of control aeration tank of sludge settling, and this has limited the scope of application of the method.Because the requirement of second pond solid-liquid separation, the mud of aeration tank can not be kept higher concentration, generally about 1.5 ~ 3.5g/L, thereby has limited biochemical reaction rate.Hydraulic detention time and sludge age interdepend, and improve volumetric loading and often form contradiction with the reduction sludge loading.System has also produced a large amount of excess sludges in operational process, its disposal costs accounts for 25%～40% of sewage work's working cost.The sludge bulking phenomenon also appears in traditional active sludge treatment system easily, contains suspended solids in the water outlet, and effluent quality is not good.
[summary of the invention]
The purpose of this utility model is exactly that speed of reaction is slow in the prior art, high in cost of production is not enough and defective in order to solve, and a kind of novel structure, high, low, the safe and reliable immersion jet membrane bioreactor of energy consumption of efficient are provided.
For achieving the above object, a kind of immersion jet membrane bioreactor is provided, comprise intake pump, jet aeration tanks, the jet-loop pump, ejector, membrane cisterna pond body, immersed type flat plate membrane component, produce water pump, put bucket and sludge pump, it is characterized in that described immersion jet membrane bioreactor is comprised of jet-flow aeration unit and film processing unit, water inlet pipe connects the jet aeration tanks water-in by intake pump, be provided with ejector in the jet aeration tanks, jet aeration tanks one side is provided with the jet-loop water outlet, the jet aeration tanks opposite side is provided with water outlet, the jet-loop water outlet connects the jet-loop pump by water pipe, the jet-loop pump connects ejector by water pipe, also be provided with the air access port on the ejector, the jet aeration tanks water outlet connects membrane cisterna pond body by water pipe, be provided with immersed type flat plate membrane component in the body of membrane cisterna pond, the immersed type flat plate membrane component top connects water outlet by pipeline, body bottom, membrane cisterna pond is provided with puts bucket, put bucket and connect jet aeration tanks by pipeline one tunnel, another road connects sludge treating system.
Described immersed type flat plate membrane component water outlet side is provided with the product water pump.
The described bucket mud extraction side of putting is provided with sludge pump.
The utility model organically combines the membrane separation technique in the separation engineering and traditional biological wastewater treatment technology, has greatly improved solid-liquid separation efficiency; And because the appearance of special efficacy bacterium, particularly dominant microflora in the increase of activated sludge concentration and the mud in the aeration tank has improved biochemical reaction rate; Simultaneously, reduce the excess sludge generation by reducing the F/M ratio, even be 0, thereby substantially solved many outstanding problems that traditional activated sludge process exists.The utility model has improved the conventional membrane bioreactor technology, adopts the mode of jet-flow aeration biochemical processing and the coupling of submerged ultrafiltration technology that sewage is carried out biochemical treatment.The sludge concentration that general membrane biological reactor process has is high except having, outside the effective advantage of mud-water separation.Because employing jet Aeration Technology and Its, the biochemical section of the utility model has very high oxygenic aeration efficient, and hydraulic detention time is short, floor space is little, and the mud-water separation section adopts the submerged ultrafiltration assembly, it is lower to go out water consumption, applicable to the place, and energy consumption and the effluent quality biochemical processing process that all has certain requirements.

[embodiment]
The utility model is described in further detail below in conjunction with accompanying drawing, and the structure of this device and principle are very clearly concerning this professional people.Should be appreciated that the specific embodiment that arrives mentioned herein only is used for explaining the utility model, and be not used in restriction the utility model.
The utility model is a kind of detachable membrane bioreactor, is divided into former and later two processing sections, and leading portion is the jet-flow aeration unit, and back segment is the submerged membrane processing unit.
In the jet aeration tanks section, sewage is after pretreatment in intake pump is delivered to jet aeration tanks, sewage is the upwelling attitude in reaction tank, sewage is pumped in the ejector under the effect of high-power jet-loop pump in the pond, the while ejector is air amount according to a certain percentage, under high velocity flow and the mutual mixing effect of air, air is cut into fine and closely woven bubble and together enters reaction tank bottom with sewage, and with the pond in sewage fully mix oxygenation.After sewage aerated reaction in the pond was complete, mud mixture to effluent weir, and flow to the aftertreatment section through overflow certainly.
In the membrane cisterna section, place a cover immersed type flat plate membrane component in the body of pond, the water outlet side of membrane module arranges the product water pump, make the inside and outside both sides of film produce pressure difference, because the aperture of filter membrane is less, only have water molecules and other can lead to filmed passing tube than small particle, this part clear water qualified discharge of generation, larger mud granule then is retained in the membrane cisterna.For avoiding the accumulation of dope in the membrane cisterna, bucket is set at the bottom of the pond, the dope that settles down is back to sludge concentration in the maintenance pond, leading portion aeration tank in the effect next section of sludge pump, and excess sludge then enters sludge treating system.
