Abstract
The utility model discloses an integration MBBR sewage treatment plant, including reactor noumenon, vertical -flow sedimentation tank, aeration pipe with pack, water inlet and delivery port are established to this reactor noumenon's upper end, the tiling of aeration pipe is in reactor noumenon's bottom, vertical -flow sedimentation tank sets up in reactor noumenon, has that one side inner wall of delivery port by baffle and reactor noumenon and constitutes, and its bottom has an interval bottom reactor noumenon, vertical -flow sedimentation tank is equipped with at the bottom port and is used for blockking that the filler gets into vertical -flow sedimentation tank's screen cloth. The device collects sedimentation tank and reactor noumenon in an organic whole, and compact structure can prevent and treat the mud and the loss of packing.
Description
Technical field
The utility model relates to technical field of sewage, specifically integrated MBBR waste disposal plant.
Background technology
MBBR (MBBR) technique is a kind of novel efficient sewage treatment process.Be the sewage treatment process between biological fluidized bed method and biological contact oxidation process, combine the advantage of the activated sludge process of suspension growth and the biomembrance process of apposition growth.Its core is exactly directly be added to as microbic activity carrier in apparatus main body using proportion close to the floating stuffing of water, relies on the castering action of the aeration in aeration tank and current to be in fluidized state.Not easily there is sludge bulking in it, the advantages such as biomembrance process processing efficiency is high, shock-resistant are also passed on, solve the problem needing regular back flushing, cleaning filtrate and change the complex operations such as aerator, overcome the shortcoming that fluidized-bed makes the fluidised power consumption of carrier excessive.
, in application process, there is following shortcoming: 1. due to the easy losing issue of mud in the settling tank that current MBBR waste disposal plant generally includes MBBR pond and is attached thereto, needs backflow; 2. filler easily runs off and causes line clogging; Supporting settling tank is often needed to use after 3.MBBR technique, the problem such as cause floor space excessive.
Utility model content
The utility model object is to provide a kind of and prevents and treats mud and filler runs off, the integrated sewage treating apparatus of compact construction, collection settling tank and reactor body and one.
The purpose of this utility model is achieved through the following technical solutions: integrated MBBR waste disposal plant, comprise reactor body, vertical sedimentation basin, aeration tube and filler, water-in and water outlet are established in the upper end of this reactor body, described aeration tube is laid in the bottom of reactor body, described vertical sedimentation basin is arranged in reactor body, by dividing plate and reactor body, there is that side inwall of water outlet to form, bottom it with bottom reactor body, there is spacing, described vertical sedimentation basin is provided with for stopping that filler enters the screen cloth of vertical sedimentation basin at bottom port.
In use, when sewage enters MBBR aeration from water-in, filler and muddy water are complete admixture, define gas, liquid, solid three-phase, for microorganism growth provides enabling environment.The collision of filler in water and shearing action, make air bubble more tiny, add the utilization ratio of oxygen.All have different biological species inside and outside each filler, some anerobes of growth inside or double oxygen bacterium, outside is bacteria as well, nitration reaction and anti-nitration reaction is existed simultaneously, thus improves treatment effect.Sewage through reaction enters into vertical sedimentation basin by the screen cloth bottom vertical sedimentation basin, and screen cloth has retained filler, and mud mixture carries out mud-water separation at settling tank.
Spacing between bottom described vertical sedimentation basin and bottom reactor body is 9-12cm.
The top of described vertical sedimentation basin is rectangle, and bottom is back taper, and the angle of bottom and horizontal plane is 60 °.
Described filler is diameter is 23mm, is highly the columniform polyethylene carrier of 10mm.The filling ratio of described filler is the 30-40% of reactor body cubic capacity.
Described screen cloth is stainless steel mesh, and mesh diameter is less than filler diameter.
Advantage of the present utility model:
The utility model vertical sedimentation basin is arranged in reactor body, reactor and vertical sedimentation basin integration, compact construction floor space is little, can not only realize the process of moving-bed biofilm reaction process to sewage, the backflow of mud can also be realized, and the loss of filler can be avoided.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. reactor body, 2. aeration tube, 3. vertical sedimentation basin, 4. filler, 5. screen cloth, 6. dividing plate.
Embodiment
Integrated MBBR waste disposal plant shown in Fig. 1 is an embodiment of the present utility model, comprises reactor body 1, vertical sedimentation basin 3, aeration tube 2 and filler 4.Water-in and water outlet are established in the upper end of reactor body 1, and aeration tube 2 is laid in the bottom of reactor body 1.Filler 4 is 23mm for diameter, and be highly the columniform polyethylene carrier of 10mm, filling ratio is the 30-40% of reactor body 1 cubic capacity.Vertical sedimentation basin 3 is arranged in reactor body 1, and the sidewall by dividing plate 6 and reactor body 1 with that side of water outlet is formed, and its top is rectangle, and bottom is back taper, and the angle of bottom and horizontal plane is 60 °.Have the spacing of 9-12cm bottom vertical sedimentation basin 3 with bottom reactor body 1, its bottom port is provided with for stopping that filler 4 enters the stainless steel mesh 5 of vertical sedimentation basin 3.The mesh diameter of screen cloth 5 is less than filler 4 diameter.
In use, when sewage enters reactor body 1 aeration from water-in, filler 4 and muddy water are complete admixture, define gas, liquid, solid three-phase, for microorganism growth provides enabling environment.The collision of filler 4 in water and shearing action, make air bubble more tiny, add the utilization ratio of oxygen.All have different biological species inside and outside each filler 4, some anerobes of growth inside or double oxygen bacterium, outside is bacteria as well, nitration reaction and anti-nitration reaction is existed simultaneously, thus improves treatment effect.Through reaction sewage in reactor body 1 from left to right after reaction after a while, vertical sedimentation basin 3 is entered through screen cloth 5 at the reaction mixture of reactor body 1 water outlet end, screen cloth 5 has retained filler 4, mud mixture carries out mud-water separation at vertical sedimentation basin 3, and the sewage after clarification is flowed out by vertical sedimentation basin 3.
