Summary of the invention
Defect for prior art, the invention provides a kind of membrane biological reaction apparatus for the sanitary sewage intensive treatment that is applicable to rural area, it can remove residual nitrogen and phosphorus in sewage more thoroughly, and reduce volume and the degree of depth of reaction tank, make the floor space reduction all corresponding to cost of device, easily accepted by rural area and other small-scale sewage processing demands.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of membrane biological reaction apparatus for the sanitary sewage intensive treatment comprises anoxic pond, strengthening pond, MBR reaction tank, aerating apparatus and pumping plant; Anoxic pond is provided with sewage inlet, between anoxic pond and strengthening pond, is provided with limbers; Strengthening is provided with the packing tower that can fill reaction medium in pond; Packing tower all communicates with strengthening pond and MBR reaction tank; Be provided with membrane bioreactor in the MBR reaction tank; The air outlet of aerating apparatus is arranged in the MBR reaction tank; Pumping plant is comprised of drinking-water pipe and lift pump, and drinking-water pipe one end connects lift pump, the other end junctional membrane bio-reactor;
Also comprise impeller, impeller is arranged in the MBR reaction tank.
In packing tower described in the utility model, the reaction medium that can fill comprises that Fe, Mg, Si, Mn and Ga etc. can realize element combinations or the simple substance of dephosphorization effect.Inorganic phosphorus and organophosphorus can be adsorbed by the reaction medium in packing tower, form microbial film, as biological nutritive element, are used.Reaction product in packing tower can regularly be taken out replacing, and the reaction product of taking-up can be used as mineral manure or bio-feritlizer, as the growing nutrient of plant.
In order to make the sewage reaction that can fully contact with membrane bioreactor, the utility model is arranged at the bottom in the MBR reaction tank by impeller, and membrane bioreactor is positioned at the top of MBR reaction tank.
Preferably, the height of MBR reaction tank is 1.5m, and the distance between the diapire of the lower end of membrane bioreactor and MBR reaction tank is 0.3m.This set can make in the situation of sewage water body convection current quickening, and the space of how accommodating untreated sewage is arranged in device, to guarantee the residuals in sewage, can both fully touch biofilm reactor.
The utility model is when application, pending sanitary sewage can enter from the sewage inlet of anoxic pond, enters the strengthening pond after the starvation of anoxic pond is processed from limbers, and then enters the packing tower in the strengthening pond, and reacted with the reaction medium in packing tower, to realize dephosphorization; Reacted sewage enters the MBR reaction tank then, and under the aeration effect and impeller effect of aerating apparatus, sewage can be fully and the membrane bioreactor contact reacts, thereby remove more thoroughly the materials such as residual phosphorus in sewage.In order more thoroughly to remove the residual phosphorus in sewage, also can be reacted with the reaction medium in packing tower again guiding to through the reacted water of MBR in the strengthening pond, and then the clear water after processing is extracted.
The beneficial effects of the utility model are: sewage can carry out three layers of processing through anoxic pond, strengthening pond and MBR reaction tank, can remove more thoroughly the materials such as residual phosphorus in sewage, nitrogen.Device is when operation, and the operation of impeller can promote the three-phase of water gas phase mud phase to mix, and in the power consumption that reduces device, makes sewage can fully touch membrane bioreactor, to guarantee clearance rate.The setting in strengthening pond is the dephosphorization effect of optimization device further.Due to the setting of impeller, the utility model can have been saved floor space by the smaller volume of device on the basis that guarantees the sewage clearance rate, has reduced cost simultaneously, can meet the demand of rural domestic sewage treatment simultaneously.In addition, the impeller in the utility model is very easy to realize as required automatically controlling.
The accompanying drawing explanation
Figure 1 shows that a kind of specific embodiment structural representation of the present utility model.
Embodiment
For content of the present utility model is become apparent more, below in conjunction with the drawings and specific embodiments, be described further.
In conjunction with Fig. 1, the utility model, for the membrane biological reaction apparatus of sanitary sewage intensive treatment, comprises anoxic pond 1, strengthening pond 2, MBR reaction tank 3, aerating apparatus 6 and pumping plant 5; Anoxic pond 1 is provided with sewage inlet, between anoxic pond 1 and strengthening pond 2, is provided with limbers 11; Strengthening is provided with the packing tower 21 that can fill reaction medium in pond 2, and packing tower can be by be provided with limbers on outer wall, thereby all communicate with strengthening pond 2 and MBR reaction tank 3; Be provided with membrane bioreactor 4 in MBR reaction tank 3; The air outlet of aerating apparatus 6 is arranged in MBR reaction tank 3; Pumping plant 5 is comprised of drinking-water pipe 51 and lift pump, and drinking-water pipe 51 1 ends connect lift pump, the other end junctional membrane bio-reactor 4; Impeller 7 is arranged in MBR reaction tank 3.
