Description
Technical field
The present invention relates to sewage treatment field more particularly to domestic sewage in rural areas, city domestic sewage, trade effluents to mention
Transformation field is marked, can also be applied to the emergency processing in river, the emergency processing upgrading of pumping plant.
Background technique
The main processing difficulty of domestic sewage in rural areas is the instability of flow of whole day, is generally focused in the morning, afternoon and evening, and the time is not
By 4 hours, the sewage quantity of discharge accounted for the 50%-80% of total displacement, more demanding to the impact resistance of equipment, needed thus
Mating conditioning tank and pumping plant, civil engineering cost and equipment cost are high.
Secondly, rural area rain dirt does not shunt, primary sedimentation tank need to be generally set, is taken up a large area, and during rural sewage treatment
Denitrogenation dephosphorizing is needed, MBR technique is such as used, although can be very good denitrogenation dephosphorizing, general membrane flux is relatively low, is easy hair
Filming pollution, not easy to clean after fouling membrane and replacement, maintenance cost is big, moreover rural sewage treatment project is more, each villages and small towns compared with
Dispersion, to reduce occupied area, most of sewage-treatment plants are all embedded in underground, cause maintenance of equipment difficult.
The oxidation Ditch Technology in sewage treatment is applied, technical maturity can be stablized effectively under suitable working condition
Processing sewage up to standard, but the complex situations such as do not shunt for country sewage instability of flow, rain dirt, except need to configure conditioning tank,
Outside primary sedimentation tank, it is also necessary to design aerobic and oxygen, Anaerobic Treatment ditch, then be equipped with secondary settling tank, with conventional mentality of designing, technique stream
Journey is long, equipment is more, treatment effect can not also be stablized effectively, cannot be advantageously applied in rural sewage treatment.
Therefore, the technical problem of above-mentioned country sewage fails to obtain effective solution always.
Summary of the invention
The object of the present invention is to provide a kind of pot type oxidation ditch integrating devices of intermittent duty, and occupied area is small, equipment at
This low, convenient transportation can effectively solve country sewage flow is big in short-term, the dirty treatment effect raw regardless of miscarriage of rain is undesirable to ask
Topic, main innovation are to be oxidation ditch form by tank design, and oxidation ditch is interior to be discharged using bottom aeration aerating and water decanter,
Formula of having a rest carries out sewage treatment, both improves convenience for later period maintenance, and impact resistance is strong, without adding conditioning tank, pumping plant, just heavy
Other facilities such as pond, flexible adaptation are stablized effectively in the discharge period of country sewage, treatment effect, and structure is simple, is convenient for industry
Change application.
For achieving the above object, the technical scheme is that a kind of integrated dress of the pot type oxidation ditch of intermittent duty
It sets, including tank body, water inlet pipe, outlet pipe, it is characterised in that be separated by partition in tank body, form two oxidation ditches in length direction
Channel, two oxidation ditch channel head and the tail water are connected to form circulation；Water inlet is equipped at the head end of tank body, a corresponding oxidation ditch channel
Pipe, the end of tank body are corresponded to equipped with outlet pipe at another oxidation ditch channel, and two oxidation ditch channels are interior at least provided with a bottom
Portion's aerator and a water decanter, the water decanter bottom are equipped with hose and are connected with outlet pipe.Country sewage is from water inlet pipe stream
It is separate in carrying out aerobic reaction in the region at the aerator of bottom in circulation in two oxidation ditch channels after entering tank body
Simultaneous oxygen/anaerobic reaction is carried out in region at the aerator of bottom, after running a period of time, precipitating is then complete by water decanter
At draining.
Further, bottom aerator can be perforation, tubular type, board-like, disc type, one kind of jet aerator or group
It closes.
Be equipped with further to promote treatment efficiency, in the oxidation ditch of tank body suspension Ball-type packing and/or square filler and/
Or the hollow sphere filler of built-in sponge filler, volume capacity of the filler in oxidation ditch are 15%-30%.Flowing filler adds
Add, in foring MBBR fluidized bed effect in oxidation ditch, realize activated sludge process, contact oxidation method, activated sludge and contact
Technique coexists in oxidation (filler surface film), enhances sewage treatment capacity.
Bottom aerator in the tank body oxidation ditch channel of optimization designs two, and one is disposed adjacent to the oxidation of water inlet pipe
In ditch channel, one is disposed adjacent in the oxidation ditch channel of outlet pipe.It is oxygenated by aerator, as oxygen concentration is aoxidizing
Aerobic and oxygen and opposite anaerobic reaction occur for the variation in ditch.Under normal circumstances, corresponding water inlet pipe oxidation need to only be opened
The aerator of ditch channel front, if the ammonia-nitrogen content of sewage is higher in tank, water outlet ammonia nitrogen is unqualified, then needs to open two simultaneously
A aerator.
Further, the intracorporal partition of tank is the plate body of section at least one group symmetrical wave crest and trough, easy at trough
In gathering floating stuffing.Most preferably, partition is the plate body or zigzag plate body or waveform plate body that section is S-shaped.
Further, impeller can be added in the intracorporal oxidation ditch of tank, to help through circulating for water flow.
Further, water decanter is that pontoon type decanting device or push-down water decanter, water decanter are made of stainless steel or plastics.
When actual motion, since country sewage discharge is concentrated in the morning, afternoon and evening, water decanter, which strains the water time, should avoid water use peak in the morning, afternoon and evening
Phase.
To guarantee that equipment operates normally, mesh enclosure is added outside water decanter, impeller.
Further, tank body material is hollow winding PP, and heat insulation effect is good.
Further, the water inlet pipe of tank body, outlet pipe are equipped with solenoid valve and/or motor-driven valve.It is connect before the water inlet pipe of tank body
The water outlet of integrated prefabricated pumping plant.Integrated prefabricated pumping plant, water inlet pipe/water outlet tube valve of tank body, impeller, bottom aeration
Device, water decanter are controlled by PLC console signal, realize the water flow of integrated prefabricated pumping plant, the intake-outlet of tank body
Opening and closing and flow, the revolving speed of plug flow device and direction, the aeration quantity of aerator and aeration time, water decanter strain the water time
Auto-control.
The beneficial effects of the present invention are:
1. tank design at oxidation ditch form, realizes oxidation ditch circulation in tank body, effective solution country sewage is short
Flow is big in time, the big problem of impact strength, without adding conditioning tank and pumping plant, and asking of not shunting of country sewage rain dirt
Topic can also oxidation ditch tank body through the invention disposably solve, no longer need to add primary sedimentation tank, greatly reduce and civil engineering and set
Standby cost.
2. bottom aerator, impeller, water decanter are arranged in tank body oxidation ditch, the time that can be discharged according to country sewage
The adjustment equipment cycle of operation, applicability are stronger.
