Background technology
With increasing for urban population, the progressively increasing of the water requirement and water consumption in city.In terms of water environment, municipal administration is dirty
The pollution pressure of water is the most serious, and the sewage disposal in whole city is all via municipal wastewater treating stations, but at municipal wastewater
There is accident in reason station, or during processing unit failure, municipal sewage can continue to produce, and municipal wastewater treating stations can not be right
Its discharge is prevented, and causes the pollution of waterhead during its maintenance and enlarging serious.Therefore municipal wastewater emergency processing needs
To adequate solution, some existing emergency treatment devices are bad to municipal wastewater treatment effect, and sewage treating efficiency is low, and
The situation of untreated sewage pollution water environment is easily caused when sewage quantity is larger.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of municipal wastewater proposed should
Anxious processing unit.
To achieve these goals, the utility model employs following technical scheme:
Design a kind of municipal wastewater emergency treatment device, including sewage-treatment plant, sterilization pool and sewage overflow storage tank, institute
To state and be provided with housing outside sewage-treatment plant, the housing is cylindrical, and the case top side is provided with sewage inlet pipe,
Opposite side is provided with overflow pipe, and the overflow pipe is connected with sewage overflow storage tank, and the enclosure interior is set gradually from top to bottom
Have the first sewage disposal layer, expand flowing plate and the second sewage disposal layer, the second sewage disposal layer end be provided with mud chamber and
Clean water chamber, the second sewage disposal layer communicate with mud chamber, and are enclosed construction between clean water chamber, the mud chamber with it is clear
Pellicle dividing plate is provided between hydroecium, the clean water chamber is connected with sterilization pool.
Preferably, it is provided with the first sewage disposal layer and the second sewage disposal layer for attached growth of microorganisms
Filler.
Preferably, expansion discharge orifice is tiltedly installed with the expansion flowing plate, the expansion discharge orifice annular array is on flowing plate is expanded.
Preferably, the mud chamber is set in the same horizontal line with clean water chamber, and the mud chamber side is provided with impurity
Discharge pipe, the clean water chamber side are provided with outlet pipe, and the outlet pipe leads to sterilization pool, and the sterilization pool side is provided with row
Water pipe.
The utility model proposes a kind of municipal wastewater emergency treatment device, beneficial effect is:First sewage disposal layer,
Second sewage disposal layer can then sink to being in that the pollutant of suspension, colloid and dissolved state is adsorbed and decomposed in sewage
Form sediment and filter, sewage overflow storage tank collects overflow sewage, and the municipal wastewater emergency treatment device can be efficient to municipal wastewater
Handled, improve municipal wastewater treatment effeciency, alleviated municipal wastewater emergency processing pressure, can enter when sewage quantity is excessive
Row storage, avoids untreated sewage from polluting environment, reduces the pollution to environment, ensure the safety of water resource.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-2, a kind of municipal wastewater emergency treatment device, including sewage-treatment plant 1, sterilization pool 2 and sewage overflow
Storage tank 3 is flowed, the outside of sewage-treatment plant 1 is provided with housing 11, and the housing 11 is cylindrical, the top side of housing 11
Sewage inlet pipe 111 is provided with, opposite side is provided with overflow pipe 112, and the overflow pipe 112 is connected with sewage overflow storage tank 3, institute
State and be disposed with the first sewage disposal layer 12 inside housing 11 from top to bottom, expand the sewage disposal layer 14 of flowing plate 13 and second, institute
State the end of the second sewage disposal layer 14 and be provided with mud chamber 15 and clean water chamber 16, the second sewage disposal layer 14 and mud chamber 15
Communicate, and be enclosed construction between clean water chamber 16, pellicle dividing plate 17 is provided between the mud chamber 15 and clean water chamber 16,
The clean water chamber 16 is connected with sterilization pool 2.
The first sewage disposal layer 12 in the second sewage disposal layer 14 with being provided with filling out for attached growth of microorganisms
Material;It is tiltedly installed with the expansion flowing plate 13 and expands discharge orifice 131, the expansion annular array of discharge orifice 131 is on flowing plate 13 is expanded;It is described heavy
Shallow lake room 15 is set in the same horizontal line with clean water chamber 16, and the side of mud chamber 15 is provided with impurity exhaust conduit 19, described clear
The side of hydroecium 16 is provided with outlet pipe 18, and the outlet pipe 18 leads to sterilization pool 2, and the side of sterilization pool 2 is provided with drainpipe
21。
Operation principle:First sewage disposal layer 12 and the second sewage disposal layer 14 can in sewage in suspend, colloid and
