A kind of sewage disposal system
Technical field
The utility model belongs to water-treatment technology field, and in particular to a kind of sewage disposal system.
Background technology
As economic develops rapidly, various places enterprise is more and more, and sewage disposal becomes each enterprise and solution is badly in need of in government
A big problem certainly.
Existing sewage disposal system, has the following disadvantages:
1st, processing system is single, it is impossible to which diversification processes sewage;
2nd, complex structure, high cost;
3rd, sewage disposal is not thorough.
Utility model content
The purpose of this utility model is to propose a kind of sewage disposal system, overcomes the deficiencies in the prior art, and it has knot
Structure is easy, low cost, the features such as can process various source of sewage, good sewage processing effect.
In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:
A kind of sewage disposal system, including the collection of kitchen oil-polluted water collecting pipe, Domestic sewage collecting pipe, wash water
, every slag bath, septic tank, physical sedimentation pond, contact-oxidation pool, the kitchen oil-polluted water collecting pipe is connected by pipeline for pipe, oil removal
To oil removal every slag bath, Domestic sewage collecting pipe is connected to septic tank by pipeline, and wash water collecting pipe is connected to by pipeline
Physical sedimentation pond, the oil removal is connected to contact-oxidation pool every slag bath, septic tank, physical sedimentation pond by pipeline.
The oil removal includes being disposed thereon the screen pack in portion every slag bath, for filtering the waste residue of kitchen oil-polluted water.
The oil removal is provided with side by side multiple division boards in slag bath, for isolating the waste oil of kitchen oil-polluted water.
The physical sedimentation pond includes first stage precipitation tank, second-level settling pond, three-level sedimentation basin, wash water is carried out multistage
Precipitation is filtered.
The contact-oxidation pool is sealing structure, and its top is provided with steam vent.
The beneficial effect of sewage disposal system described in the utility model is:It has features simple structure, and low cost can be processed
The features such as various source of sewage, good sewage processing effect.
Description of the drawings
Fig. 1 is the folded state schematic diagram of sewage disposal system described in the utility model.
Specific embodiment
Preferred embodiment of the utility model is described in further detail below.
As shown in figure 1, described sewage disposal system, including kitchen oil-polluted water collecting pipe, Domestic sewage collecting pipe, wash
Sewage collecting pipe, oil removal are washed every slag bath, septic tank, physical sedimentation pond, contact-oxidation pool, the kitchen oil-polluted water collecting pipe leads to
Cross pipeline and be connected to oil removal every slag bath, Domestic sewage collecting pipe is connected to septic tank by pipeline, and wash water collecting pipe passes through
Pipeline is connected to physical sedimentation pond, and the oil removal is connected to catalytic oxidation every slag bath, septic tank, physical sedimentation pond by pipeline
Pond.
The oil removal includes being disposed thereon the screen pack in portion every slag bath, for filtering the waste residue of kitchen oil-polluted water.
The oil removal is provided with side by side multiple division boards in slag bath, for isolating the waste oil of kitchen oil-polluted water.
The physical sedimentation pond includes first stage precipitation tank, second-level settling pond, three-level sedimentation basin, wash water is carried out multistage
Precipitation is filtered.
The contact-oxidation pool is sealing structure, and its top is provided with steam vent.
Contact oxidation method is a kind of new wastewater biochemical facture for having activated sludge process and biomembrance process feature concurrently.Not
Equipped with fillers such as coke, gravel, plastic honeycombs in ventilative aeration tank, filler is submerged by water, and is exposed in filler bottom with air blast
Gas oxygenation, air can carry pending waste water secretly from bottom to top, pass freely through filtrate part and reach ground, after air runaway, give up
Water then from up to down returns bottom of pond in filtrate layout.Activated sludge is attached to filler surface, does not flow with water, because biomembrane is directly received
To the strong agitation of ascending air, constantly update, so as to improve clean-up effect.Biological contact oxidation process has process time
Short, small volume, good purification, effluent quality it is good and stablize, sludge be not required to backflow also do not expand, the advantages of power consumption is little.Waste water
Middle organic matter major part Jing after contact-oxidation pool biological treatment is effectively removed.

Above content is the further description done to the utility model with reference to specific preferred embodiment, is easy to
The those skilled in the art are understood that and apply the utility model, it is impossible to assert and of the present utility model be embodied as only limitation
In these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the utility model structure
Some simple deduction or replace can also be made on the premise of think of, without through performing creative labour.Therefore, art technology
, according to announcement of the present utility model, the simple modifications made to the utility model all should be in protection model of the present utility model for personnel
Within enclosing.
