Description
[technical field]
The utility model relates to the water conditioning technical field, specifically a kind of external placed type 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 multiple MBR 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 easily appears in the traditional active sludge treatment system, contains suspended solids in the water outlet, and effluent quality is not good.
[summary of the invention]
It is little in order to solve in the prior art scope of application that the purpose of this utility model is exactly, and speed of reaction waits defective and deficiency slowly, and a kind of novel structure, external placed type jet membrane bioreactor that technique effect is good, safe and reliable are provided.
For achieving the above object, a kind of external placed type jet membrane bioreactor is provided, comprise intake pump, jet aeration tanks, the jet-loop pump, ejector, the film intake pump, the film recycle pump, type external tubular membrane, film scavenging pump and film clean water tank, it is characterized in that described external placed type 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 is by pipeline junctional membrane intake pump, the film intake pump is by pipeline junctional membrane recycle pump, the film recycle pump connects type external tubular membrane by pipeline, the type external tubular membrane water outlet is leaded up to pipeline and is connected water outlet, water tank inlet is cleaned by the pipeline junctional membrane in another road, film cleans water outlet of water tank by pipeline junctional membrane recycle pump, the type external tubular membrane end is provided with circulating outlet, the type external tubular membrane circulating outlet is leaded up to pipeline and is connected mud discharging mouth and jet aeration tanks, and another road is by pipeline junctional membrane recycle pump.
Described film cleans water outlet of water tank one side and is provided with the film scavenging 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 is a kind of improvement of conventional art, adopts the mode of jet-flow aeration biochemical processing and the coupling of external placed type ultrafiltration membrane technique that sewage is carried out biochemical treatment.The sludge concentration that general MBR technique 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 external placed type hyperfiltration membrane assembly, and floor space is little, and is convenient to safeguard and change, applied widely, it is equally applicable to effluent quality, processes have higher requirements treatment process under the occasion of land used and system stability.

[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.
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 external membrane processing unit.
In the jet-flow aeration unit, sewage is after pretreatment in intake pump enters 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 entered the aftertreatment section through overflow.
The film processing unit is made of many groups external pipe type hyperfiltration membrane assembly; the aeration tank water outlet is delivered in the system by the film intake pump; and under the effect of film recycle pump, enter the film pipe; owing to having pressure difference inside and outside the film pipe; therefore comprise the water molecules particle that size is less in interior sewage and can enter film pipe opposite side through the ultra-filtration membrane surface; water outlet after the filter forms the ultrafiltration clear liquid; a part of qualified discharge wherein; another part then is stored in film and cleans in the water tank; larger-size mud granule and organism then are retained in the film pipe outside and form dope; terminal membrane recycle pump place circulating filtration was processed before part dope was back to film processing system; another part is back to the jet-flow aeration unit to keep sludge concentration in the aeration tank, and the residue dope then enters the sludge treatment unit.In addition, the film scavenging pump also need be set in the ultra filtration unit problem that product water filter that back flushing causes to reduce film to pollute reduces is carried out in film pipe inboard.
