Abstract
The invention belongs to technical field of sewage, and in particular to a kind of sewage-treatment plant.A kind of device of sewage disposal, the tank body set including solid, water inlet is located at the bottom of tank body, the top of aeration zone sets aerator, the under-filled filler of recirculating zone, supernatant after precipitation is flowed into effluent trough, and is discharged by outlet pipe, and the sludge after precipitation is discharged from the discharge pipeline of the opposite side of tank body lower part water inlet.The method have the benefit that：The present invention uses mechanical aeration, waste water and sludge are sufficiently mixed by the stirring of aerator, and make the continuous renewal of mixed liquor liquid level and air contact, to increase the dissolved oxygen in water, and the steam rate of climb caused by steam generator is fast, forms bubble, improve contact area, the further content for improving dissolved oxygen, the filling adsorption fine particle in recirculating zone reduce the sludge quantity of sewage, and the setting of deflector also improves the effluent quality of sewage.
Description
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of sewage-treatment plant.
Background technology
The feature that ammonia nitrogen concentration is too high, causes carbon-nitrogen ratio to be less than 4 is generally presented in China's town sewage.Bio-denitrifying sewage
Process includes three ammonification, nitrification and denitrification processes.Ammonification and nitrifying process need aeration to reach that organic nitrogen and ammonia nitrogen is complete
The purpose of full conversion nitrate nitrogen, energy consumption are huge.Denitrification process needs to provide enough organic matters turn the nitrate nitrogen in water body
Turn to nitrogen.And conventional processing procedure, part nitrogen are to absorb ammonia nitrogen removal by the own growth demand of microorganism
, it is practically without leaving sewage plant part, but be transferred in sludge, and it is released into digestion again in sludge handling process
In liquid, digestive juice foldback enters waste water processes, adds processing load.Conventional aerator processing sewage can not make mixed liquor
Liquid level and air contact, it can not preferably increase the dissolved oxygen in water, so as to which the content of dissolved oxygen can not be improved.Further, since
Sewage is needed to undergo different environment, sewage is constantly distributed and flowed back in whole handling process, and the discharge rate of sludge is higher
And the effluent quality of sewage is poor.
The content of the invention
The technical problems to be solved by the invention：Sewage is handled for current conventional aerator, can not preferably be increased
Dissolved oxygen in water, cause the content of dissolved oxygen relatively low, the problem of discharge rate of sludge is higher and the effluent quality of sewage is poor,
Provide a kind of sewage-treatment plant.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
A kind of sewage-treatment plant, including the three-dimensional tank body set, the tank body is interior to include Bao Qi Qu ﹑ precipitation Qu ﹑ recirculating zones, enters
The mouth of a river is located at the bottom of tank body, and steam caused by steam generator is together into the aeration zone among tank body beside sewage and tank body
Interior, the top of aeration zone sets aerator, and the sewage part in aeration zone is flow in the recirculating zone of aeration zone side, recirculating zone
Under-filled filler, aeration zone another part sewage flow to opposite side, and is flow to by deflector in settling zone, after precipitation
Supernatant flow into effluent trough, and discharged by outlet pipe, the sludge after precipitation is from the opposite side of tank body lower part water inlet
Discharge pipeline is discharged.
The steam generator is that water is heated to 101 ~ 120 DEG C, produces steam.
The aeration zone uses mechanical aeration, is aerated 2 ~ 3 times, 1 ~ 2h, aerator open setting by button control every time.
The filler be Gui Zao Tu ﹑ Shi Ying Sha ﹑ activated carbons any one.
Compared with other method, advantageous effects are the present invention：The present invention uses mechanical aeration, passes through stirring for aerator
Mixing is sufficiently mixed waste water and sludge, and makes the continuous renewal of mixed liquor liquid level and air contact, to increase the dissolved oxygen in water, and
The steam rate of climb is fast caused by steam generator, forms bubble, improves contact area, further to improve containing for dissolved oxygen
Measure, the filling adsorption fine particle in recirculating zone reduces the sludge quantity of sewage, and the setting of deflector also improves sewage
Effluent quality.

Embodiment
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the embodiment of the present invention is carried out it is clear, completely retouch
State, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on the present invention
In embodiment, all other reality that those skilled in the art is obtained on the premise of creative work is not made
Example is applied, belongs to protection scope of the present invention.
The present invention is a kind of sewage-treatment plant, including the three-dimensional tank body 1 set, includes the ﹑ of aeration zone 3 in the tank body 1
The ﹑ recirculating zones 11 of settling zone 4, sewage enter from the bottom water inlet 2 of tank body 1, and steam generator 13 is heated to 101 ~ 120 by water
DEG C, steam is produced, sewage and steam together enter in the aeration zone 3 among tank body 1, and steam constantly rises to the top of aeration zone 3
Aerator 5, further increase oxygen in water, aeration zone 3 uses mechanical aeration, makes waste water by the stirring of aerator 5
It is sufficiently mixed with sludge, and makes the continuous renewal of mixed liquor liquid level and air contact, to increase the dissolved oxygen in water, aerator 5
The button control by top is opened, Shi is simple with Fang Bian ﹑, aerator unlatching 2 ~ 3 times, every time 2 ~ 3h, a part in aeration zone 3
Sewage flow in the recirculating zone 11 of the side of aeration zone 3, after adsorbing tiny suspended particulate by the filler 12 of the bottom of recirculating zone 11,
