Description
Technical field
The present invention relates to sewage disposal system and processing method, more particularly to a kind of country sewage biological treatment system and place
Reason method.
Background technology
Country sewage has that water quality is complicated, scattered, the characteristics of not concentrating, and substantial amounts of organic matter, part are contained in sewage
The nutriments such as hardly degraded organic substance, ammonia nitrogen and phosphorus.Such as effectively processing not in time, arbitrarily discharge in environment, ring around can be caused
The serious pollution of border especially water environment such as the eutrophication of water body or stagnant water phenomenon, threatens people’s lives environment and body
Health.
Traditional rural sewage treatment be usually used activated sludge process, artificial swamp, land treatment system, at biomembrane
Reason system etc..But these traditional technologies take up a large area, treatment effeciency is low, complicated for operation, water outlet be difficult to it is up to standard；And it generates
A large amount of sludge generate secondary pollution.Rural economic development is also unable to catch up with cities and towns, area feature protrusion etc. at present simultaneously, therefore new
Rural sewage treatment system construction is there is an urgent need to economic, efficient, automation is high integrated processing system, to adapt to China rural area
Diversity of sewage etc..So as to solve the problems, such as that rural domestic sewage treatment is difficult, take up a large area, operation and maintenance difficulty.
The content of the invention
Goal of the invention：During the present invention provides the current rural sewage treatment of solution, system footprint area is big, treatment effeciency
It is low, the problems such as complicated for operation, high energy consumption, sludge yield is big.It is a further object of the present invention to provide a kind of country sewage biologies
Processing method can efficiently handle country sewage.
Technical solution：A kind of country sewage biological treatment system of the present invention, comprising several anaerobic ponds and several aerobic
Pond；The anaerobic pond is filled with anaerobism victory enzyme group；The aerobic tank is filled with aerobic prompt enzyme group；Several anaerobic ponds include extremely
Few first anaerobic pond and second anaerobic pond；Several aerobic tanks include at least an aerobic tank.
In first anaerobic pond, anaerobism victory enzyme group accounts for the 4-10% of the first anaerobism pool volume；In second anaerobic pond,
Anaerobism victory enzyme group accounts for the 2-10% of the second anaerobism pool volume.In the aerobic tank, aerobic victory enzyme group accounts for the first aerobic pool volume
2-6%.
Prompt enzyme group used in the present invention is the porous carrier for being embedded with high-effective microorganism, carrier aperture 7nm-20nm it
Between.What is embedded in anaerobism victory enzyme group is anaerobe；What is embedded in aerobic victory enzyme group is aerobic microbiological.The density of prompt enzyme group
For 1.1g/cm3；Anaerobism victory enzyme group by anaerobism victory enzyme group in use, be directly placed into anaerobic pond device.Anaerobic pond is anti-in anaerobism
Answer device bottom, the intake design of anaerobic reactor is into bottom in and top out type.Aerobic victory enzyme group is placed into aerobic tank, and aerobic tank is good
Oxygen reactor bottom.Aerobic tank bottom needs uniform aeration, adjusts aeration quantity and causes prompt enzyme group energy is enough just to fluidize in the reactor
It is advisable.
The present invention sewage from the first anaerobic pond to the second anaerobic pond when, part anaerobism victory enzyme group can be flowed into current
Second anaerobic pond, therefore the present invention is disposed in anaerobic reactor water outlet and blocks component；The component that blocks is water outlet baffle
Composition, for zigzag, the angle of the side wall of the water outlet baffle and anaerobic reactor is 30-60 °.Blocking component can be fine
The anaerobism victory enzyme group avoided in the first anaerobic pond be flowed into the second anaerobic pond, ensure that the recycling rate of waterused of system.By
When the sewage of aerobic tank processing flows into the first anaerobic pond or discharge, the aerobic prompt enzyme group in part can be distributed in current, therefore good
The water outlet of oxygen reactor is provided with strainer, and strainer can be very good to filter aerobic prompt enzyme group, ensure that system recycling rate of waterused
And treatment effeciency.
Using the sewage water treatment method of above-mentioned country sewage biological treatment system, comprise the following steps：(1) sewage is passed through
The processing of first anaerobic pond, processing time 3-10h；(2) sewage handled through the first anaerobic pond is sent into the processing of the second anaerobic pond, place
The reason time is 3-10h；(3) and then aerobic tank processing, processing time 5- will be sent by the sewage of the second anaerobic pond processing
12h；(4) 20-60% of the sewage by aerobic tank processing is returned to the first anaerobic pond, rest part discharge.
Preferably, in step (1), the processing time is 3-5h.
Preferably, in step (2), the processing time is 3-5h.
Preferably, in step (3), the processing time is 7-10h.
Preferably, in step (4), the 40-50% of the sewage volume by aerobic tank processing is returned to the first anaerobic pond.
Heretofore described processing time is hydraulic detention time (HRT).
In the present invention, in step (4), it is that treated that will pass through aerobic tank treated the reason for sewage flowed back
COD of sewage and remaining pollutant decline, and are sent to the first anaerobic pond, after raw sewerage processing, play dilute
The effect of sewage is released, the sewage after dilution is reached by subsequent step processing《Urban wastewater treatment firm pollutant emission mark
It is accurate》(GB18918-2002) the level-one A standards in, can directly discharge.
By reflow treatment, solve in existing sewage disposal process, it is necessary to utilize water-reducible step.Because directly
One is diluted with water to be the increase in the volume of the processing of sewage, sewage treating efficiency reduces；In addition it is then to waste substantial amounts of money
Source；Also increase processing cost simultaneously.In addition, reflow treatment can solve the tedious steps of sewage disposal, if without returning
Stream process adds processing time, it is necessary to increase anaerobic and aerobic processing, and treatment effeciency is also extremely lowly, and to add processing
Cost.
Unless otherwise indicated, heretofore described " % " is percent by volume.
Advantageous effect：The present invention have efficiently, floor space is small, operation is simple, effluent quality is high, does not generate the spies such as sludge
Point.Whole system operation is simple, is kept an eye on without special messenger, and longtime running is without specially safeguarding；Water outlet is up to level-one A standards.Especially
It is suitble to small-sized, decentralized rural sewage treatment.
