Abstract
The utility model discloses a novel fluidized-bed biofilm reactor, which comprises a reactor body, multiple microorganisms placed in the reactor body and a suspending carrier for the microorganisms to attach, wherein the reactor body is provided with a water outlet. For the novel fluidized-bed biofilm reactor disclosed by the utility model, kieselguhr is used as suspending fillers and has the advantages of high filling rate, more voids and large surface area, so that more attachment areas are supplied for microorganisms, the kieselguhr is very suitable for microorganism growth, and the microorganisms are strong in activity and resistance; the suspending kieselguhr can be used to wash out a surface biofilm to realize growth balance, thus, the sewage treatment capacity and the quality of discharged water are increased greatly, and the sewage treatment cost is reduced; meanwhile, the kieselguhr is non-toxic and harmless and cannot lead to secondary pollution; and in addition, the bottom inside the reactor body is provided with an aeration device, so that the sewage treatment effect is further enhanced and the sewage treatment cost is further reduced.
Description
Technical field
The utility model relates to fluidized bed bio membrane reactor art, refers in particular to a kind of novel fluidized bed biofilm reactor.
Background technology
Biomembrance process is an important technology of modern WWT, and it is usually used in handling sewage, industrial sewage and repairs natural water etc.
This technology system realizes through the fluidized bed bio membrane reactor; Usually the less inert particle with one type in sand, gac is that carrier is filled in the fluidized-bed; Because little, the overall surface-area of its carrier granule is big, thus the living weight in the treatment facility unit volume.The carrier of aforementioned fluidized-bed is in fluidized state, sewage from its underpart, left and right side flows through, extensively and continually contact with microbial film; Little owing to carrier granule again at bed internal ratio comparatively dense, mutual frictional impact, therefore; Biomembranous activity also than higher, strengthened mass transfer process, quickened pollutent transmittance process to microorganism cells from sweat; Simultaneously, because carrier effectively prevents latch up phenomenon ceaselessly flowing.
But in the above-mentioned prior art, its sewage treatment capacity and effluent quality are still not ideal enough, are difficult to satisfy high sewage treatment capacity, high effluent quality, requirement cheaply, by this, need work out better scheme and solve the problems referred to above.
The utility model content
In view of this, the utility model is to the disappearance of prior art existence, and its main purpose provides a kind of novel fluidized bed biofilm reactor, and it has improved sewage treatment capacity and effluent quality, has reduced cost for wastewater treatment.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of novel fluidized bed biofilm reactor includes reactor body and places the multiple mikrobe of this reactor body and the suspending carrier of confession microorganic adhesion, and wherein, this reactor body offers water outlet, and this suspending carrier is a zeyssatite.
As a kind of preferred version, said reactor body inner bottom part is provided with aerating apparatus.
As a kind of preferred version, said aerating apparatus is a pump type aerating apparatus.
As a kind of preferred version; The water outlet of said reactor body has water collecting basin through pipe connection; This water collecting basin is connected with water circle device, and this water circle device includes rising pipe, pump and the water inlet pipe that connects in order, and the other end of this rising pipe and water inlet pipe is connected in aforementioned water collecting basin.
The utility model compared with prior art has tangible advantage and beneficial effect, particularly, can be known by technique scheme:
One, utilize zeyssatite to do floating stuffing, its packing fraction is high, and diatomaceous space is many, surface-area is big, and the microorganic adhesion area is many; Be fit to very much microbial growth, microorganism active is strong, resistibility is strong, and suspension zeyssatite can wash away the microbial film on surface; Form the growth balance, so, improved sewage treatment capacity and effluent quality greatly; Simultaneously, zeyssatite is nontoxic, can not cause secondary pollution;
Two, previous reaction device body inner bottom part is provided with aerating apparatus, prevents that effectively reactor body inner suspension filler from sinking, and organism, mikrobe contact with dissolved oxygen in the reinforcement reactor body; Simultaneously the liquid in the reactor body has been carried out oxygenation; So, guarantee in the reactor body there be under the condition of sufficient dissolved oxygen mikrobe, to organic oxygenolysis in the sewage; Further strengthen wastewater treatment efficiency, also reduced cost for wastewater treatment.
Be constitutional features and the effect of more clearly setting forth the utility model, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.

Embodiment:
Please with reference to shown in Figure 1; It has demonstrated the concrete structure of the preferred embodiment of the utility model; Include the suspending carrier of reactor body 10 and multiple mikrobe that places this reactor body 10 and confession microorganic adhesion, wherein, this reactor body 10 offers water outlet.
This this suspending carrier is a zeyssatite 20, and its space is many, surface-area is big, and the microorganic adhesion area is many, is fit to very much microbial growth; These zeyssatite 20 packing fractions are high, can reach 70%; In the liquid agitation, suspension zeyssatite 20 can wash away the microbial film on surface, forms the growth balance; Utilize zeyssatite 20 as suspending carrier, the resistibility of aforementioned micro organism more, activity is stronger by force, compares conventional art, effectively improves 2～3 times of sewage treatment capacity, and improved effluent quality.
These reactor body 10 inner bottom parts are provided with aerating apparatus 30; This aerating apparatus 30 is a pump type aerating apparatus; It both provided oxygen for mikrobe; For aforementioned zeyssatite power is provided again, has strengthened that organism, mikrobe contact with dissolved oxygen in the reactor body 10, help having strengthened wastewater treatment efficiency.
And; The water outlet of previous reaction device body 10 has water collecting basin 40 through pipe connection; This water collecting basin 40 is connected with water circle device 50; This water circle device 50 includes rising pipe 51, pump 52 and the water inlet pipe 53 that connects in order, and the other end of this rising pipe 51 and water inlet pipe 53 is connected in aforementioned water collecting basin 40.
The design focal point of the utility model is that main system utilizes zeyssatite to do floating stuffing, and its packing fraction is high, and diatomaceous space is many, surface-area is big; The microorganic adhesion area is many, is fit to very much microbial growth, and microorganism active is strong, resistibility is strong, and suspension zeyssatite can wash away the microbial film on surface; Form the growth balance, so, improved sewage treatment capacity and effluent quality greatly; Simultaneously, zeyssatite is nontoxic, can not cause secondary pollution.
