Description
Technical field
The present invention relates to sewage treatment field more particularly to a kind of water decanters for urban sewage treatment system.
Background technique
Integrated sewage treating apparatus is that a heavy pond, I, II grades of contact-oxidation pools, secondary settling tank, sludge-tank are concentrated one
Equipment, and blast aeration is carried out in I, II grades of contact-oxidation pools, it has been effectively combined contact oxidation method and activated sludge process
Come, the advantages of both being provided simultaneously with, and the shortcomings that both overcome, further increases sewage treatment level.It uses both at home and abroad
There are many sewage treatment process, wherein be broadly divided into activated sludge process and two kinds of biofilm, our common common aerations, oxygen
Change ditch method, A/B method, A2/O are owned by France in the former, and biological rotating disk, contact oxidation method belong to the latter.Integrated sewage treating apparatus is
The equipment that one heavy pond, I, II grades of contact-oxidation pools, secondary settling tank, sludge-tank are concentrated into one, and in I, II grades of contact-oxidation pools
The advantages of carrying out blast aeration, be effectively combined contact oxidation method and activated sludge process, being provided simultaneously with the two, and overcome
The shortcomings that the two, further increases sewage treatment level.
Prior art discloses one kind application No. is: a kind of 201220079467.6 urban wastewater treatment is integrally disguised
Set, the urban wastewater treatment integrated apparatus include sequentially connected grid canal, conditioning tank, hydrolysis acidification pool, contact-oxidation pool,
Coagulating basin, inclined-tube sedimentation tank, sterilization pool, flow channel；Waste water of the invention by grid canal remove bulk sundries, after be discharged into tune
Pond, hydrolysis acidification pool are saved, the Sludge Bed that Pollutants in Wastewater is hydrolyzed acidification pool is retained, will be high through absorption, assimilation and decomposition
Molecule, complicated organic matter resolve into low molecule, simple organic matter, and sewage enters catalytic oxidation after being come out by hydrolysis acidification pool
Pond is assimilated and is decomposed under conditions of aerobic pollutant in water, ultimately generates CO2 and H2O, then through coagulating basin, tube settling
Pond, sterilization pool, flow channel realize qualified discharge, but the urban wastewater treatment integrated apparatus itself uses chemical Treatment, has
Cause the hidden danger of secondary pollution.
Summary of the invention
In view of the above-mentioned problems, solving cities and towns the present invention provides a kind of water decanter for urban sewage treatment system
Integrated sewage treatment device itself uses chemical Treatment, there is the problem of hidden danger for causing secondary pollution.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: one kind being used for urban sewage treatment system
Water decanter, structure include sewage conduct, grid, collecting-tank, water inlet, aqueduct, booster pump, setting pot, aeration tank,
Stomata, secondary sedimentation tank, return pipe, sand removing hole, coagulating basin, the mouth of falling agent, sedimentation basin, filtering ponds, filter plate, discharge outlet；It is described
Grid is installed on sewage conduct, the collecting-tank is connect with sewage conduct, and water inlet is installed on the collecting-tank, described defeated
Waterpipe is connect with collecting-tank, is installed with booster pump on the aqueduct.
Further, the return pipe is connect with aeration tank and secondary sedimentation tank, is installed with sand removing hole on the return pipe.
Further, the coagulating basin is connect by aqueduct with secondary sedimentation tank, is installed with down on the coagulating basin
Agent mouth.
Further, the sedimentation basin is connect with coagulating basin.
Further, the filtering ponds are connect with sedimentation basin, are installed with filter plate on the filtering ponds.
Further, the discharge outlet is connect with filtering ponds.
By the above-mentioned description to structure of the invention it is found that compared to the prior art, the present invention has the advantage that
The present invention is using the suspended matter in grid and setting pot twice filter sewage, using in Wastewater Treated by Activated Sludge Process sewage
Colloid and dissolved organic matter sewage is reached into discharge standard, whole process uses object finally by coagulation, precipitating, filter sewage
Logos processing, not will cause new pollution hidden trouble.
Detailed description of the invention
