Technical field
The present invention relates in the technical field of sewage disposal, more particularly to a kind of excess sludge reuse technology.
Background technology
Since country sewage facility process points are disperseed, unification of having no idea excludes sludge, is put into and excludes not in time
The sludge of accumulation can have an impact final outflow water water quality, and a large amount of manpower and materials can be expended again by separately taking out mud.
Invention content
The invention mainly solves the technical problem of providing a kind of excess sludge reuse technologies, make script residue that can not discharge
Sludge be able to reuse, increase the anaerobism time, improve biochemical ability, consume a certain amount of sludge, to reducing sludge
Number is discharged, maintenance workload is reduced and plays a big part, water inlet reflux is passed through regulating reservoir and in a disguised form accelerates anaerobic processes, returns
Flowing water stream can accelerate anaerobism again energy saving the stirring of regulating reservoir.
In order to solve the above technical problems, one aspect of the present invention is:Provide a kind of excess sludge reuse
Technique, including regulating reservoir, anaerobic pond, aerobic tank and sedimentation basin, the effective valve of reflux added between regulating reservoir and anaerobic pond
Part water is passed back into regulating reservoir, recirculation water is passed through regulating reservoir by gate backflow water yield processed during regulating reservoir water feeding of water pump
Stirring, the sludge reflux of sedimentation basin, the sludge deposited in sedimentation basin is flowed back by return duct, between anaerobic pond and regulating reservoir
Branch is formed, with valve regulated, sludge reflux is entered into anaerobic pond respectively and regulating reservoir carries out secondary anaerobism.
In a preferred embodiment of the present invention, the bottom of the sedimentation basin and regulating reservoir is provided with mud return line
Road.
In a preferred embodiment of the present invention, the sludge of the sedimentation basin is back to adjusting by sludge return pipe
The bottom in pond.
The beneficial effects of the invention are as follows:The excess sludge reuse technology of the present invention makes the remaining sludge that can not be discharged originally
It is able to reuse, increases the anaerobism time, improves biochemical ability, consumes a certain amount of sludge, to reducing the discharge time of sludge
Number reduces maintenance workload and plays a big part, and water inlet reflux is passed through regulating reservoir and in a disguised form accelerates anaerobic processes, backwater
Anaerobism can be accelerated again energy saving the stirring of regulating reservoir.
Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, wherein:
Fig. 1 is the flow diagram of a preferred embodiment of excess sludge reuse technology of the present invention.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
As shown in Figure 1, the embodiment of the present invention includes:
A kind of excess sludge reuse technology, including regulating reservoir, anaerobic pond, aerobic tank and sedimentation basin, regulating reservoir and anaerobic pond it
Between plus a reflux effective valve control backflow water yield part water is passed back into tune during regulating reservoir water feeding of water pump
Pond is saved, recirculation water is passed through regulating reservoir stirring, the sludge reflux of sedimentation basin, and the sludge deposited in sedimentation basin is returned by return duct
Stream, forms branch between anaerobic pond and regulating reservoir, with valve regulated, sludge reflux is entered anaerobic pond respectively and regulating reservoir carries out
Secondary anaerobism.
Further, the bottom of the sedimentation basin and regulating reservoir is provided with sludge return pipe.Wherein, the precipitation
The sludge in pond is back to the bottom of regulating reservoir by sludge return pipe.Excess sludge in sedimentation basin is discharged into regulating reservoir,
Anaerobic processes occur in regulating reservoir again simultaneously, the Anaerobic Treatment main function of sludge is the decrement of sludge, is stablized and harmless, and
It to a certain extent using the energy and substance generated, creates good conditions for follow-up sludge treatment, to reduce to a certain extent
Sludge.
Intake what pump power can be stored much larger than sewage since the amount of a whole set for the treatment of process sewage per treatment is limited
Amount, so the water of some needs to back flow back into regulating reservoir during water inlet, adjusting is passed through by the sewage of reflux with pipeline
Stirring action plays to the anaerobic processes carried out in regulating reservoir in bottom of pond portion.
In conclusion the excess sludge reuse technology of the present invention, enables the remaining sludge reuse that can not be discharged originally, increases
The anaerobism time is added, has improved biochemical ability, consumed a certain amount of sludge, to reducing the discharge number of sludge, has reduced and safeguard
Workload plays a big part, and water inlet reflux is passed through regulating reservoir and in a disguised form accelerates anaerobic processes, and backwater is to regulating reservoir
Stirring can accelerate anaerobism again energy saving.
Since scouring of wool is not high with water water quality requirement, the tail water after processing is up to standard can be used to scouring of wool production, realize Mobe
Closed cycle, scouring of wool production no longer need fresh water, to realize that scouring of wool produces waste water water zero-emission.
In conclusion the excess sludge reuse technology of the present invention, realization has waste water from washing wool water zero-emission, while to printing and dyeing
Waste water provides nitrogen and phosphorus element, also supplements the trace elements such as boron manganese molybdenum, improves disposal effect of dyeing wastewater, reduce
Treatment of dyeing wastewater cost.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
