Utility model content
The purpose of this utility model is to provide a kind of microkinetic combined film bioreactor, the utility model it is beneficial
Effect is to be extremely suitable for the regeneration processing of domestic sewage in rural areas from far-off regions, and processing cost is low.
Technical solution used by the utility model be include stabilization pond, raw water tubes access stabilization pond and provide original for stabilization pond
Water, biologic packing material and membrane module are immersed in stabilization pond, and biologic packing material is arranged along the long setting in the pond of stabilization pond, membrane module steady
Determine the end on the pool, outlet pipe is accessed in membrane module by peristaltic pump, and the water in membrane module is discharged, and backwash tube passes through backwash
Water pump accesses in membrane module, provides backwashing water for membrane module.
Further, membrane module is micro-filtration or ultrafiltration membrane.
Further, the flow-shape of stabilization pond is pulling flow type.
Specific embodiment
The utility model is described in detail With reference to embodiment.
As shown in Figure 1, microkinetic combined film bioreactor includes stabilization pond 8, raw water tubes 1 access surely the utility model
Determining the pool 8 is that stabilization pond 8 provides raw water, biologic packing material 2 and micro-filtration or hyperfiltration membrane assembly 3 is immersed in stabilization pond 8.Stabilization pond 8
Flow-shape be pulling flow type, the end of stabilization pond 8 is arranged in along the long setting in the pond of stabilization pond 8, membrane module 3 in biologic packing material 2.
Outlet pipe 5 is accessed in membrane module 3 by peristaltic pump 4, and the water in membrane module 3 is discharged, and backwash tube 7 passes through recoil
In 6 access membrane module 3 of wash water pump, backwashing water is provided for membrane module 3.
Biofacies in the stabilization pond 8 of the utility model mainly includes bacterium, fungi, protozoan, rear life compared with horn of plenty
Animal, algae and aquatic macrophyte etc., oxygen in stabilization pond 8 are photosynthetic mainly from air reaeration and water plant
Effect.The upper layer of stabilization pond 8, solar ray energy irradiate the position penetrated, are aerobic layer;The bottom of stabilization pond 8, by the sludge that precipitates and
The sludge blanket that the algae for declining dead and mushroom are formed is anaerobic layer;There are a facultative layer, the layers between aerobic layer and anaerobic layer
Survival is aerobic-anaerobic microbe, they can be using the oxygen to dissociate in water, also can be under anaerobic from NO3 -Or CO3 2-In take the photograph
Take oxygen.
After raw water to be processed enters stabilization pond 8, along the long plug-flow flowing in pond, in aerobic microbiological, anaerobe, algae
Under class, the collective effect of aquatic macrophyte, organic matter, nitrogen, phosphorus and other polluters can be effectively removed.8 end of stabilization pond
The water at end realizes solid and liquid separation under the swabbing action of peristaltic pump 4, through membrane module 3, and treated water is eventually by outlet pipe 5
Outflow.In order to keep higher membrane flux, periodic operation backwash pump 6 backwashes membrane module 3.
It is artificial with using since the oxygen in stabilization pond 8 mostlys come from the photosynthesis of air reaeration and water plant
The traditional activated sludge process of aeration is compared, which can substantially reduce operation power cost.In addition, peristaltic pump 4 and backwash
The motor of water pump 6 can be supplied by solar power generation.Therefore, the power cost of the technique is extremely low.The technique is extremely suitable for partially
The regeneration processing of remote area countryside sanitary sewage.Raw water can effectively remove organic matter and nutrients after the process
Matter, effluent quality is excellent, water outlet can be used for municipal administration use mixedly, irrigated farmland and landscape water, the new agriculture in China can be greatly promoted
Village's construction and ecological agriculture construction.
The above is only the better embodiment to the utility model, not makees any form to the utility model
On limitation, all according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations
With modification, it is all within the scope of the technical scheme of the utility model.
