Description
Technical field
The utility model relates to the field of deodorization in sludge drying pond, bright can be directed to existing medium and small rule more particularly, to one kind
The sludge drying pond of mould Sewage Disposal project sludge drying pond deodorization problem.
Background technique
Existing rural sewage treatment scale of the project is small, and the sludge quantity of generation is little, and sludge is largely regular by fecal suction truck
Appointed place is cleaned to be handled.Some projects are provided with sludge drying pond, but do not carry out deodorizing process.Some project sludge
Processing not in time, or even is dealt with improperly, causes secondary pollution, it is relatively high that secondary pollution receives resident's complaint.Therefore sludge is used
Pond stores sludge, is periodically cleared up by fecal suction truck and no the sludge drying pond way of progress deodorizing process will be restricted gradually.
Utility model content
In conclusion to solve the technical problems existing in the prior art, the utility model discloses one kind and removes with biology
The sludge drying pond of smelly function effectively can carry out deodorizing process for sludge drying pond in middle and small scale Sewage Disposal.
In order to achieve the above objectives, specific technical solution is as follows:
A kind of sludge drying pond with biological deodorizing function comprising sewage treatment unit, sludge lifting component and dirt
Mud mummifying pool, the sludge drying pond are located above the sewage treatment unit and pass through at the sludge lifting component and sewage
Manage the sedimentation basin connection of unit;
The middle layer in the sludge drying pond is provided with a joint-cutting double-wall corrugated pipe, forms a sludge memory block, which deposits
Filter assemblies are provided with below storage area, bacteria bed is provided with above the sludge memory block, the biology for forming sludge drying pond removes
Smelly structure.
Further, the filter assemblies include from the coarse filtration layer that the sludge drying bottom of pond is set gradually upward, in it is thick
Filter layer, thin filter layer.
Further, a filtered water collection pipe is additionally provided under the filter assemblies, at the filtered water collection pipe and sewage
Manage the conditioning tank connection in unit.
Further, the bacteria bed is a biomembrane, is placed in sludge drying pond upper surface.
Further, the sewage treatment unit include the conditioning tank being sequentially communicated, anoxic pond, aerobic tank, sedimentation basin and in
Between pond, the sedimentation basin is that precipitating, accumulation have the pond body of sludge.
Further, the lifting assembly includes sludge pump, sludge pipe, the sludge pump loaded on sludge pipe one end and protrude into
In the sedimentation basin, and the other end of sludge pipe is arranged in the joint-cutting double-wall corrugated pipe.
Compared to existing technologies, as follows the advantages of the utility model:
The utility model is directed to existing middle and small scale Sewage Disposal project sludge drying pond deodorization problem, proposes solution party
Case.The sludge that treating stations generate is pipelined to sludge drying pond middle layer, and sludge drying pond uses joint-cutting double-wall corrugated pipe
As sludge memory block, the sewage sludge storage time is longer, and has certain degradation to organic matter.Memory block lower layer is set as thick
The filtering material carefully arranged in pairs or groups crosses drainage and enters conditioning tank, and sludge is made to play the role of desiccation, and memory block upper layer is the life of certain altitude
The foul smell that object filter bed sludge generates is gradually risen by bacteria bed gap, it is with stink odor when gas flows through filter material surface
Chemical dissolution enter and be decomposed after the biomembrane of filter material surface;The oxygen in air enters bacteria bed, gas simultaneously
Oxygen contained in body enters biomembrane also by dissolution, provides necessary oxygen for the growth and breeding of biomembrane, thus reaches
Deodorization purpose.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.
A kind of sludge drying pond with biological deodorizing function comprising sewage treatment unit 1, sludge lifting component 2 and
Sludge drying pond 3, the sludge drying pond 3 be located at 1 top of the sewage treatment unit and by the sludge lifting component 2 with
The sedimentation basin of sewage treatment unit 3 is connected to.
The sewage treatment unit 1 include be sequentially communicated conditioning tank 11, anoxic pond 12, aerobic tank 13, sedimentation basin 14 and
Intermediate pool 15, the sedimentation basin 14 are precipitating, accumulate the pond body for having sludge.Specifically: the water inlet of the conditioning tank 11
For sewage inlet, and it is provided with the draw-off pump for extracting sewage into anoxic pond in the conditioning tank 11 and is connected to aspiration pump
Extraction tube, the extraction tube are connected to the anoxic pond 12, and the anoxic pond 12 and two aerobic tanks 13 are contacted, in each aerobic tank 13
It is provided with aeration tube, aeration nozzle is provided on aeration tube, the precipitating funnel for being inverted triangle is provided in the sedimentation basin 14,
The lifting assembly 2 stretches in the precipitating funnel.
The middle layer in the sludge drying pond 3 is provided with a joint-cutting double-wall corrugated pipe 4, forms a sludge memory block, the sludge
Filter assemblies 5 are provided with below memory block, are provided with bacteria bed 6 above the sludge memory block;The filter assemblies 5 include from
Coarse filtration layer 51 that 3 bottom of sludge drying pond is set gradually upward, middle coarse filtration layer 52, thin filter layer 53, the biological filter
Bed 6 is a biomembrane, is placed in 3 upper surface of sludge drying pond.
