Description
Technical field
The present invention relates to field of sewage treatment equipment, more particularly relates to a kind of urban wastewater treatment equipment.
Background technology
As the substantial amounts of people in the countryside in China pour in cities and towns, urban population is continuously increased, and the water resource in cities and towns is by tight
Destroy again, China is faced with the problem of water resource is exhausted.Water resource is guarantee for the survival of mankind, it is non-renewable money
Source, it not only influences the production and living of people, more has important influence to the national conditions state fortune in China.It can be seen from the above that strengthen
The urban wastewater treatment work in China is very urgent.Town sewage is mainly sanitary sewage, industrial wastewater discharged in cities and towns etc.
It is mainly to collect rear or by cities and towns sewage treatment plants' processing by the sewage network in cities and towns to be discharged into afterwards Deng, these waste water
Water body.In recent years, the town sewage discharge capacity in China is being continuously increased.And the wastewater pollution source in China mainly have industrial source,
Agricultural sources, urban life source and least a portion of centralization pollution facilities exhaust source, wherein, tool relevant information is shown, cities and towns life
The main reason for quantity of wastewater effluent living is increase China's quantity of wastewater effluent.It can be seen from the above that although China has been set up at many sewage
Factory is managed, the urban wastewater treatment work in China is still not enough in place.Therefore, a kind of sewage disposal device is invented to handle cities and towns dirt
Water, to promoting sewage disposal development and water conservation recycling to be of great significance.
The content of the invention
To solve the above problems, the present invention, which provides a kind of urban wastewater treatment equipment, includes reaction tank, filler, filtrate, interior
Cylinder and outer barrel；Inner cylinder, outer barrel are equipped with the reaction tank；Reaction tank is divided into three areas by the inner cylinder, outer barrel, inside inner cylinder
Region is settling zone, and the region between inner cylinder, outer barrel is bio-contact oxidation area, and the region between outer barrel and reaction tank pool wall is
Filtering area；The outer barrel bottom is equipped with multiple flowing holes；The settling zone is equipped with water inlet；The filtering area is equipped with water outlet.
The filler is arranged in bio-contact oxidation area；The filtrate is arranged in filtering area.
Further, the precipitation district center is equipped with central tube, and the central tube includes central tube, loudspeaker from top to bottom
Mouth, reflecting plate.
Further, the filler is soft-filler.
Further, the filtrate includes coke, rubble.
Further, the reaction tank is cylindrical structure, and reaction tank bottom is inverted conical.
Further, the top of the reaction tank is equipped with flase floor.
The invention has the advantages that：
1st, using precipitation, bio-contact oxidation, biofilter process combination, eliminate two needed for usual urban wastewater treatment
Heavy pond, floor space are small.
2nd, sludge yield is low, operation and maintenance are simple, operating cost is few.

Embodiment
It is attached below in conjunction with specification in order to allow those skilled in the art to more fully understand and realize technical scheme
Figure and specific embodiment are described in further details.
Embodiment 1
As shown in Figure 1, a kind of urban wastewater treatment equipment includes reaction tank, filler, filtrate 9, inner cylinder 4 and outer barrel 5；The reaction
Inner cylinder 4, outer barrel 5 are equipped with pond；Reaction tank is divided into three areas by the inner cylinder 4, outer barrel 5, and the region inside inner cylinder 4 is settling zone
1, the region between inner cylinder 4, outer barrel 5 is bio-contact oxidation area 2, and the region between outer barrel 5 and reaction tank pool wall is filtering area
3；5 bottom of outer barrel is equipped with multiple flowing holes 51；The filtering area 3 is equipped with water outlet.
The filler is soft-filler 7, is arranged in bio-contact oxidation area 2；The filtrate includes coke, rubble, if
Put in filtering area 3.
The reaction tank is cylindrical structure, and reaction tank bottom is inverted conical.2 bottom of settling zone 1 and bio-contact oxidation area
Portion is designed with mud discharging mouth.
1 center of settling zone is equipped with central tube 6, and central tube is divided into central tube 61, horn mouth 62, reflecting plate from top to bottom
63。
The top of the reaction tank is equipped with flase floor, staff may stand on flase floor to the sewage in reaction tank into
Row such as feeds intake, observes, detecting at the work.
The reaction tank bottom is equipped with stent 10.
In the embodiment, the specific implementation process of sewage disposal is as follows：
Sewage enters the settling zone 1 of equipment from the top of central tube 6, and impurity, the suspended matter contained in sewage is sunk in settling zone 1
Form sediment, the sediment after precipitation falls into the bottom of settling zone 1, is discharged by mud discharging mouth, removes the sewage after partial impurities, suspended matter
Supernatant overflow enters bio-contact oxidation area 2 by the upper surface of inner cylinder 4, and bio-contact oxidation area 2 is equipped with soft-filler 7,
The aerator 8 that 2 bottom of bio-contact oxidation area is set is aerated sewage, and institute is provided for aerobic bacteria on soft-filler 7
