The co-walled realization integrated design of unit cells.
The present invention also provides a kind of sewage treatment process, are handled using above-mentioned integration apparatus, treatment process includes
Following steps：
(a) sewage is imported into biochemical zone, three-phase separation area is entered after biochemical treatment；
(b) by three phase separation, gas, sludge reflux to biochemical zone are excluded, sewage enters sand filtration area；Under biochemical zone
Portion sets sludge outlet, for excluding to be back to the partial sludge of biochemical zone；
(c) after sand filtration, clear water is obtained, clear water is from clear water zone discharge up to standard.
Preferably, the sludge concentration in the biochemical zone is 6000-10000mg/L.
In existing sewage disposal technology, secondary settling tank is considered as required and important structure in traditional activated sludge process technique
Object is built, but in practical application, there is some shortcomings for secondary settling tank, such as take up a large area, power consumption is high, effluent quality is got dirty
The problems such as mud settling property influences greatly, to be discharged SS higher, and water outlet mud scum is more.Secondary settling tank effect mainly makes mud mixture point
From, do not detach gas-liquid-solid mixture, the gas that biochemical zone aeration generates can make a part of mud mixture float, so as to
Cause secondary clarifier effluent effect undesirable, especially SS；The sludge reflux mode of secondary settling tank is typically chosen sludge reflux pump or gas
Propose reflux, power consumption is relatively large, therefore in order to New foul water disposal facility it is small, compact-sized, efficient will
It asks and is consistent, the sewage disposal of the invention patent research design efficiently, inexpensive means a great.
In the three-phase separation area of the present invention, it can substantially be divided into gas, mud-water separation, three portions of mud-water separation and sludge reflux
Point.Gas, mud-water separation are mainly the separation between gas and mud mixture, and mud-water separation is mainly the separation of sludge and water, dirty
Mud reflux refers to that sewage is entered the sludge (high concentration mud mixture) deposited in three-phase separation area by biochemical zone and flowed back again
To biochemical zone (i.e. biochemical reaction zone).Entered by the most of liquid, solid and a small amount of gas of biochemical zone by seam, due to sludge
High sludge concentration and a small amount of bubble may be such that in recirculating zone forms significant density contrast in Nei He areas of this area outer fluid, so as to generate
Recycle stream, this recycle stream contributes to the reflux of sludge, and can rise liquid and be separated with the approach of sludge reflux,
So as to achieve the effect that mud-water separation.Meanwhile a small amount of gas can be collected between first baffle and second baffle, pass through exhaust
Pipe is discharged in air, so as to fulfill gas, mud, water three phase separation.The gas gathering mask that first baffle is formed with second baffle can be protected
It demonstrate,proves the gas mud mixture being not properly separated further to detach, sludge can preferably be avoided to enter the precipitation of three-phase separation area
Area.
The three-phase separation area can effectively carry out gas and water, mud separation, make gas and water, mud separating effect more notable, shock resistance
Load-bearing capacity is strong；And the three phase separator is simple in structure, reasonable design, can make fabricated construction, stablizes with civil engineering structure and ties
Fast Installation is closed, may be alternatively configured civil engineering structure.
The three-phase separation area of the present invention can supplement sludge in the case where not needing to be additionally provided the energy to biochemical zone, carry
The sludge concentration of high biochemical zone, sludge concentration can reach 6000-10000mg/L.Biochemical zone is by being aerated, precipitation, stands the stage,
It realizes anaerobism, anoxic, aerobic alternating state, there is good Nitrogen/Phosphorus Removal.Pollutant is decomposed into small point in the process
Sub- organic matter, after and by oxygenolysis be CO2、H2O etc. is synthesized into microbial cell.COD, BOD can be improved5, ammonia nitrogen etc.
Organic matter degradation effect.Water outlet after continuous biochemical treatment enters three-phase separation area, the sludge one of three-phase separation area separation
Biochemical zone is partly refluxed to, improves the sludge concentration of biochemical zone, a part drains into sludge-tank by mud discharging device.By three-phase
The sludge of Disengagement zone also has a little SS, and sewage further ensure that water outlet SS, at sand filtration area further across sand filtration area
The sewage qualified discharge of reason.
The invention has the advantages that the three phase separator improves gas collection effect, solid-liquid separation effect further carries
Height, effluent quality is good, simple in structure, greatly reduces cost；High degree of automation, low energy consumption, increases sludge in aeration tank
Concentration, Nitrogen/Phosphorus Removal is notable, and water outlet can stably reach level-one A Effluent criterias.A kind of sewage disposal device of the present invention
And technique, the secondary settling tank in conventional processes is replaced with three-phase separation area, not only mud-water separation effect is good, but also also improves
Biochemical zone sludge concentration, further improves effluent quality, and effluent quality can stably reach《Urban wastewater treatment firm pollutant
Discharge standard》(GB18918-2002) the level-one emission standard A in.
