Description
Technical field
The invention belongs to technical field of sewage, more particularly to a kind of movable container formula sewage-treatment plant.
Background technology
With the development of China's economic society, water resources crisis and water environment pollution increasingly sharpen, the discharge of all kinds of sewage
Amount is significantly increased, serious threat water body environment, it has also become one of focus of domestic and international field of Environment Protection concern.Residential quarters, village,
Villages and small towns, office building, market, hotel, restaurant, sanatorium, office, school, army, hospital, highway, railway, factory, ore deposit
Mountain, tourist attraction sanitary sewage and it is similar therewith butcher, the middle-size and small-size technical scale organic sewage such as processing of aquatic products, food
Processing and reuse typically use integrated sewage treating apparatus, water quality can typically reach national sewage disposal comprehensive discharge standard
Primary standard.But overhaul of the equipments is being run into, or when the system failure, this part of contaminated water can not be handled, often just directly
Discharge, causes the pollution of environment.
Present integrated sewage treating apparatus typically uses buried installation.There are following some shortcomings：
1. it is unfavorable for repairing, after equipment breaks down, it has not been convenient to maintenance and replacing.This is typically that owner is most worried.
2. pair environmental suitability is strong, winter is antifreeze, summer flood control, and the north needs to be embedded to deeper, and does isothermal holding.
3rd, device is fixed somewhere, is used as some sewage disposal device, when sewerage water quality and quantity changes,
Or system jam, entirely cannot normal operation.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of movable container formula sewage-treatment plant.
A kind of movable container formula sewage-treatment plant, by container body and the other assemblies being integrated into container body
Composition；Component in container body includes drawing liquid pump, one-level MBBR reactors, two level MBBR reactors and the precipitation being sequentially connected
Pond, there is delivery port on the outside of sedimentation basin, the sludge outlet of sedimentation basin bottom is connected by pneumatic diaphragm pump with folded spiral shell formula filter press,
The pneumatic diaphragm pump is connected with gas suspension air blower；
Component in container body also includes:
Chemicals dosing plant, it is connected respectively with one-level MBBR reactors, two level MBBR reactors by pipeline and valve；
Workbench, for chemically examining sewage and stacking medicine and instrument；
Switch board, for monitoring the operation with control device；
Power supply, it is connected by cable with automobile engine.
In addition to bottom plate and close to the baffle plate of headstock, remaining can be opened container body on four sides, facilitate the maintenance of equipment
With maintenance, and eye-catching LOGO can be sprayed with outside the enclosure portion to show the device.
One-level MBBR reaction tanks, two level MBBR reaction tanks bottom are provided with aerator and are provided with valve, can automatically adjust
Aeration quantity.Reaction tank uses PE translucent materials, light, corrosion-resistant, observable inner stuffing running situation.
Sedimentation basin uses radial-flow, sets central tube and inclined plate packing, is intake from central tube, and from by passing through on the outside of casing
Delivery port is discharged.Swash plate is set in the middle part of sedimentation basin, increases sedimentation effect, the sludge to precipitate is discharged from cone bucket bottom.

Pump can use air caused by gas suspension air blower as source of the gas.
Folded spiral shell formula filter press can automatically adjust rotary drum rotating speed, differential speed step-less adjustment, so as to ensure according to sludge concentration
The separating effect of sludge.Simultaneously can be convenient with automatic self-cleaning, repair and maintenance.Meet unattended needs.
Chemicals dosing plant, it is made up of a dosing tank and 2 dosing pumps.Dosing weight is selected according to water water quality.It can reach
Acted on to SS, turbidity, dephosphorization, degerming etc. is removed.Add medicament such as calcium hydroxide, flocculant, sodium hypochlorite etc..
The sewage disposal technology of the present apparatus is moving bed biological film sewage treatment device (Moving Bed Biofilm
Reactor, abbreviation MBBR), it is by adding a number of suspending carrier into sewage-treatment plant, improving sewage disposal dress
Biomass and biological species in putting, so as to improve the treatment effeciency of sewage-treatment plant.
, it is necessary to which the time of at least 2~3 days overhauls when scattered sewage-treatment plant goes wrong, and it is longer
Recovery debugging cycle, but Small Sewage Treatment Equipment can not store sewage again, and this part of contaminated water will turn into Environmental security
Hidden danger.Sewerage integrated device is generally fixed to ground or is embedded in underground, does not possess moveable characteristic.The present invention uses
A kind of vehicle-mounted movable container formula sewage-treatment plant, mobility strong, the situation of various bursts is coped with, is being connected to report
Short time after announcement can reach sewage disposal scene, and quickly start and sewage is handled.MBBR has volumetric loading
It is high, impact resistance is strong, stable performance, reliable, flexible, many advantages, such as simple is safeguarded, so MBBR is to be adapted to car
The sewage disposal technology of the movable container formula integrated sewage treating apparatus of load.
The problem of for traditional integrated sewage treating apparatus, and combine emergency situations, temporarily emergent needs, the present invention
Using the integrated sewage treating apparatus of container-type, can be transported to equipment by truck needs sewage scene to be processed, is not required to
Want crane, it is not necessary to install, in this embodiment it is not even necessary to which external power supply, chargeable power supply, the present apparatus can also be run and be no less than close to the inner portion
24h.The beneficial effects of the present invention are：
(1) relatively conventional integrated sewage treating apparatus, it is buried, the characteristics of in place rear immovable is lifted, the present apparatus uses
The flat cargo containers appearance and size of the chi of standard 20：5.85mX2.23mX2.15m.Special medium-sized general wagon can be equipped with, Gu
It is set for the delivery vehicle for the device.
(2) the device is equipped with mobile battery supply unit, can connect 380V/220V power source charges, or and automobile engine
Matching, by engine-driven gearing automatic charging.Can be continuous to run more than the 24h times in the case of no charging.Also may be used
Charged with directly connecing external power supply to device.
(3) the two level MBBR integrated apparatus that the device uses, equipment is few, low in energy consumption, high treating effect.Excess sludge is arranged
