The enhanced treatment device adopts the combination of the rotating biological disks of two stages and the anaerobic digester to conduct anaerobic and aerobic treatment to the digestion supernatant, and is provided with a dosing device to remove nitrogen and phosphorus in the supernatant to reduce the impact effect to a system caused by backflow of the supernatant.
Description
Technical field
The utility model relates to the sewage sludge combined treatment equipment that can be applicable to the sludge from wastewater treatment plant digestion process, what be specifically related to is sludge digestion supernatant strengthening and processing device.
Background technology
Municipal effluent is main at present to adopt biological method to handle; In treating processes, need the discharging excess sludge; Contain a large amount of undegradable organism in the excess sludge, undegradable organism generally adopts anaerobic digestion by amphimicrobe and obligatory anaerobic bacteria degradation treatment, and the mud discharging after the processing carries out subsequent disposal; And still contain a large amount of nitrogen phosphorus after the digestion process in the mud supernatant; Supernatant is back to Sewage treatment systems, will certainly produce bigger impact to Sewage treatment systems, influences treatment effect.
Summary of the invention
The purpose of the utility model provides sludge digestion supernatant strengthening and processing device, the problem big to system shock when being back to sink drainage of the mud supernatant when this sludge digestion supernatant strengthening and processing device is used to solve present employing biological method Treating Municipal Sewage after the digestion process.
The utility model solves the technical scheme that its technical problem adopted: this sludge digestion supernatant strengthening and processing device is provided with aerobic zone and anaerobic zone on the top of anaerobic digester; Aerobic zone communicates with anaerobic zone; Aerobic blodisc is set in the aerobic zone, the anaerobe rotating disk is set in the anaerobic zone, the return line that draw the anaerobic digester bottom is connected to aerobic zone; Return line is provided with lift pump and static mixer, and anaerobic zone is provided with sewage outlet; Aerobe rotating disk, anaerobe rotating disk are connected with the blodisc drive unit respectively.
The front end of the return line that anaerobic digester is drawn in the such scheme is provided with filter, makes the sludge quantity of taking away in the supernatant that is back to aerobic zone with the suction function that reduces lift pump.
Also connect a dosing pump in the such scheme before the static mixer.
The blodisc drive unit is a motor in the such scheme, and motor has two, and a motor connects aerobic blodisc through rotation axis, and another motor connects the anaerobe rotating disk through rotation axis.
The utlity model has following beneficial effect:
1, the utility model adopts two-stage biological rotating disk and anaerobic digester combination, and anaerobism and aerobic treatment digestion supernatant are provided with administration device simultaneously, accomplish the removal to nitrogen phosphorus in the supernatant, alleviate supernatant and reflux to the shock action of system.
2, the utility model is simple in structure, and the digestion supernatant after the processing also can directly be discharged into natural water body, has avoided the waste of re-treatment.

Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
As shown in Figure 1; This sludge digestion supernatant strengthening and processing device is provided with aerobic zone and anaerobic zone on the top of anaerobic digester 9, and aerobic zone and anaerobic zone are the pond that is provided with on anaerobic digester 9 tops, and the partition wall of aerobic zone and anaerobic zone is provided with the discharge orifice; Aerobic zone communicates through the discharge orifice with anaerobic zone; Aerobic blodisc 5 is set in the aerobic zone, anaerobe rotating disk 6 is set in the anaerobic zone, anaerobic zone is provided with sewage outlet 10; The return line that draw anaerobic digester 1 bottom is connected to aerobic zone, and the front end of return line is provided with filter 1, also is provided with lift pump 2 and static mixer 4 on the return line; Also be connected with dosing pump 3 before the static mixer 4; Offerd medicine in static mixer 4 by dosing pump 3, mix with supernatant, will guarantee enough mixing times this moment; So that static mixer 4 accomplish supernatants and coagulating agent mix the phosphorus in the removal sewage supernatant; Aerobe rotating disk 5, anaerobe rotating disk 6 are connected with the blodisc drive unit respectively; The blodisc drive unit is a motor in this embodiment; Motor has two, and a motor 7 connects aerobic blodisc 5 through rotation axis, and another motor 7 connects anaerobe rotating disk 6 through rotation axis.Digestion supernatant after static mixer 4 removes dephosphorization passes back into aerobic zone; Get into anaerobic zone after treatment; After this further handled, the most of the nitrogen in the sewage supernatant was removed, and the supernatant after the processing can be admitted to Sewage treatment systems through sewage outlet 10.
Aerobe rotating disk 5 is accomplished biomembranous oxygenation process through constantly contacting with air in the disc rotary course; The Working environment of anaerobic zone carries out certain sealing, and guarantees that the disc of anaerobe rotating disk 6 all works below the water surface, reaches the purpose of starvation, guarantees good anaerobic environment.
The blodisc drive unit needs speed control device to cooperate in the utility model, guarantees the needs of different rotating speeds.
The working process of the utility model is: at first through filter 1, lift pump 2 adds coagulating agent through dosing pump 3 and static mixer 4 and removes phosphorus before supernatant is sent into aerobe rotating disk 5 the digestion supernatant in supernatant then under the suction of lift pump 2; General selective polymerization aluminum chloride is as coagulating agent, but dosage will be controlled within the specific limits the required phosphorus amount of assurance subsequent biological treatment; The supernatant of removing most of phosphorus gets into aerobe rotating disk 5, through the effect of aerobic microbiological, removes residual COD in the supernatant; Ammonia-state nitrogen is carried out the nitrated nitric nitrogen that makes it to be converted into; In aerobe rotating disk 5, accomplished nitrated supernatant and got into anaerobe rotating disk 6 along the discharge orifice, under the anerobes effect, the nitric nitrogen in the supernatant has been carried out denitrification with oxygenizement; Finally make it from supernatant, thoroughly to remove with the form of nitrogen; After treatment, supernatant is back to Sewage treatment systems, can reduce much the total system shock action; If suitable operation, the digestion supernatant also can directly be discharged into natural water body, has avoided the waste of re-treatment.
