Using a kind of sewage water treatment method of such as above-mentioned urban sewage treatment system, it is characterised in that：Include the following steps：
1) filtration treatment of sewage：
By in sewage transport to filter chamber, sewage is entered by the water inlet of filter chamber in filter chamber suction pump first
Portion passes through the guiding function of deflector so that sewage must first pass through the processing of garbage barrier net pocket, by the suspended material in sewage and
Rubbish is removed, it is avoided to enter internal system, causes the blocking of internal system part, sewage after the processing of garbage barrier net pocket,

The processing of adsorbing bar removes the harmful substance in sewage, then pass through adsorbing bar surface by the acticarbon on adsorbing bar
Absorption villus the greasy dirt in sewage is adsorbed, effectively improve the quality after sewage water filtration, improve water body clarity；
2) Air Exposure of sewage：
(1) by treated for filter chamber, sewage enters by sewage running piping that Air Exposure is carried out in solarization air cell,
When sewage enters solarization air cell, aerator is opened, and air pump is delivered air to by air duct in aeration supervisor, then
Be diffused into aeration is in charge of by being aerated supervisor, finally from aeration be in charge of surface solarization air cap enter in solarization air cell with sewage into
Row mixing aoxidizes the reducing substances in sewage by Air Exposure, and the dissolved oxygen content being effectively increased in sewage effectively inhibits water
It is smelly, improve the transparency and water quality of water, so as to the subsequent processing of sewage of being more convenient for, effectively improve the self-purification capacity in river,
The flocculated effect of nature can be generated again simultaneously so that the molecule cohesion of sewage, subsequent precipitation process of being more convenient for；
(2) while rotating device band pneumatic aeration supervisor's rotation, electric rotating machine are opened, and electric rotating machine is driven by motor shaft to expose
Gas is responsible for 360 ° of rotations, effectively increases the aeration area of aerator, accelerates aeration rate and aeration quality so that in solarization air cell
The sewage of different location can be carried out aeration oxygen replenishing processing, while be aerated supervisor and aeration is in charge of in rotation process again to exposing
The indoor sewage of gas is stirred so that indoor sewage is aerated in state is vigorously stirred, so as to make sewage abundant with air
Contact, it is ensured that the oxygenolysis effect of sewage effectively improves the processing speed of sewage so that the organic pollution in sewage obtains
Degradation；
3) flocculation treatment of sewage：
(1) by solarization air cell, treated that sewage enters by sewage conveying tube that flocculation treatment is carried out in flocculating chamber, dirty
After water is entered in flocculating chamber, by the guiding function of vacuum partition board so that sewage is carried out along the position of vacuum partition board
Bending flowing, flows through each cavity, effectively extends sewage in the indoor time of flocculating, it is ensured that the mixing of sewage and flocculation medicament
Amount, while chemical tank is transported in each vacuum partition board, then by the medicament delivery pipe medicament that will flocculate from vacuum baffle surface
Insecticide-spraying hole enter in flocculating chamber and mixed with sewage so that the particulate matter cohesion in sewage, consequently facilitating impurity and sewage

The flow direction of mixing direction and flow is consistent, and so as to effectively improve the stir speed (S.S.) of sewage, improves the flocculating effect of particulate matter；
4) precipitation process of sewage：
By treated for flocculating chamber, sewage is entered by sewage conveying tube in mud chamber, first passes around the heavy of barrier
Shallow lake acts on, and sludge, the coagulated particles object in sewage are deposited in the bottom of mud chamber, makees using the resistance of wavy baffle plate
With, the residual impurity particle in sewage is precipitated, so that it is guaranteed that the impurity particle in sewage is cleaned, raising sewage disposal
Quality afterwards；
5) sewage is disinfected：
(1) by treated for mud chamber, sewage enters in disinfection room the processing that carries out disinfection by sewage conveying tube, into
Enter to the indoor sewage of disinfection to first pass around the spray function of water distributing tray, sewage sprayed from the water distributing pore of water distribution panel surface,
So as to increase the contact area of sewage and heating tube so that sewage is fully spread, and improves wastewater disinfection quality, and slow down sewage pair
The impact dynamics of heating tube group, while before sewage enters disinfection room, heating tube group carries out pre-add heat treatment in advance, works as dirt
When water is entered in disinfection room, heat is quickly transmitted in disinfection room by heating tube, so as to sterilize indoor sewage into
Row heating disinfection, the bacterium in water is killed, and sewage reaches discharge standard after a series of processing；
6) periodic maintenance：
Periodically sewage disposal system inside is cleared up, while is recycled in time to precipitating indoor mud,
Consequently facilitating the processing of follow-up sewage, realizes the continuity processing of sewage, accelerates sewage disposal rate.
The present invention is by adopting the above-described technical solution, have the advantages that：
The impurity in sewage is removed by filter chamber first in the present invention, garbage barrier net pocket is by the rubbish in sewage and suspension
Impurity removes, then is filtered the large granular impurity in sewage by filtering meshes, by adsorbing bar by the harmful substance in sewage
Absorption, except the stink in decontaminated water, while by adsorbing villus by the oily waste degradation in sewage on adsorbing bar so that sewage
Scavenging effect is more preferable, subsequent sewage disposal of being more convenient for, and the sewage handled by filter chamber is entered in solarization air cell by aeration
Device carries out Air Exposure, enters back into flocculating chamber and carries out flocculation treatment, and chemical tank will be flocculated medicament by medicament delivery pipe
It is transported in vacuum partition board, then is sprayed from the insecticide-spraying hole on vacuum partition board, the little particle cohesion so that in sewage is mixed with sewage
Into large particulate matter, consequently facilitating in subsequent sewage particle precipitation process, while matched with agitating device so that sewage
It is sufficiently mixed with flocculation medicament, accelerates the flocculation rate of sewage, improve the processing quality of sewage, and vacuum partition board can incite somebody to action again
Flocculating chamber is divided into multiple cavities so that sewage gradually flows through multiple cavities so that the flocculation better quality of sewage, structure design
More ingenious reasonable, then sewage enters the double action by barrier and wavy baffle plate in mud chamber so that dirty
Sludge and particle precipitation in water effectively remove the impurity of sewage, and last sewage is entered in disinfection room, and first passing through water distributing tray will
Sewage is sprayed from water distributing pore so that sewage is fully dispersed, increases the contact area between sewage and heating tube group, accelerates sewage
Disinfection rate and sterilisation quality, it is ensured that the germ in sewage is killed, while can be carried by the design of two heating tube groups
The disinfection rate of high disinfection room.
The floor space of the processing system of the present invention is small, at low cost, convenient for practical operation and use, by sewage into
Row multiple tracks processing so that water quality that treated is high, and water body is more limpid, it can be ensured that urban sewage treatment system it is long-term, strong
Health, stabilization, Effec-tive Function.
