Description

Sewage disposal system

Technical field

The utility model relates to ecological, environmental protective equipment technical field, especially a kind of sewage disposal system.

Background technique

As modernization development is accelerated, the sewage that city production and life generate also is increasing year by year, and especially life is dirty Water, because pollution sources are more, discharge amount is big, the problem of causing urban sewage pipe load heavier, frequently encounter long-pending silting plug.In order to anti- Only sewage conduct blocks, and the prior art is usually that primary filter processing unit is installed at pollution sources, and sewage is carried out tentatively Filtering and removing slag, to mitigate the pressure of subsequent sewage treatment.But existing apparatus for treating sewage is usually required to dismantle filter screen and be carried out Slagging-off cleaning, it is not only cumbersome, it is time-consuming and laborious, and apparatus for treating sewage needs to shut down, and influences normal use.

Classify according to sewage source, sewage is generally divided into production waste and sanitary sewage, production waste include trade effluent, Rural sewage and medical sewage etc..Medical sewage typically refers to hospital sewage, and water quality is complicated, is typically derived from Synthetic Wardss Sewage.Containing a large amount of pathogen, disinfectant, organic solvent, tissue waste, drug and detergent etc. in hospital sewage, together The a large amount of bacterium of Shi Hanyou, parasitic ovum and other harmful substances.Hospitals at Present sewage treatment is insufficient, and most of hospital is useless Water direct emission after simply sterilizing, or the warp for being discharged after simply being sterilized again after some filtration treatments, thus discharging Crossing the water of processing, not only Disinfection Effect is poor, and containing untreated suspended matter, a large amount of by-products etc..

Utility model content

The utility model in view of the deficiencies of the prior art, proposes a kind of sewage disposal system, and structure is simple, at low cost, behaviour Facilitate, the sewage treatment suitable for a variety of industries.

In order to realize above-mentioned purpose of utility model, the utility model the following technical schemes are provided: a kind of sewage disposal system, Including grid pond, flocculation basin, conditioning tank, settling tank, sterilization pool, secondary settling tank and silt basin, the grid pond, flocculation basin, Conditioning tank, settling tank, sterilization pool, secondary settling tank are sequentially connected；The grid pond, the settling tank and the secondary settling tank It is connect respectively with the silt basin.

Further, the bottom of the grid pond, the settling tank or the secondary settling tank is connected through spiral propeller In the silt basin.

Further, the silt basin connects filter press.

Further, the sterilization pool includes chlorinating machine, rabbling mechanism and the aeration tube for being located at bottom of pond, the chlorinating machine Outlet is connected to the aeration tube, and the rabbling mechanism is erected in the sterilization pool.

Compared with prior art, the utility model, which has the advantage that, is combined and is set using flocculation, adjusting and multistep sedimentation Meter, handles sewage, and treatment effeciency is high, and good sewage processing effect, effluent quality is good, low energy consumption, processing capacity is big.

Flocculant is added into flocculation basin, upper liquid is taken to be sent into grid pond, primary filtration is carried out by grid, reduces dirty Solid content in water is further sent into conditioning tank, adjusts pH value, being then fed into settling tank is settled, the top after sedimentation Liquid is sent into sterilization pool, and carry out disinfection processing, since disinfection is that aeration type sterilizes, is accompanied with agitating function, the liquid mixed again Body is sent into secondary settling tank's sedimentation, finally obtains purified water quality；For the bottom in flocculation basin, settling tank and secondary settling tank Portion's mud is expelled to silt basin through spiral propeller, dehydrates through filter press, can be used as Fertilizer application.

Detailed description of the invention

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings, in which:

Fig. 1 is the structural schematic diagram of the utility model sewage disposal system；

Diagram label:

1- grid pond, 2- flocculation basin, 3- conditioning tank, 31- regulator tank, 4- settling tank, 5- sterilization pool, 51- blender, 52- aeration tube, 53- chlorinating machine, 6- secondary settling tank, 7- silt basin, 8- filter press.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawing, the description of this part be only it is exemplary and explanatory, There should not be any restriction effect to the protection scope of the utility model.

As shown in Figure 1, a kind of sewage disposal system, a kind of sewage disposal system, including grid pond 1, flocculation basin 2, adjusting Pond 3, settling tank 4, sterilization pool 5, secondary settling tank 6 and silt basin 7, the grid pond 1, flocculation basin 2, conditioning tank 3, settling tank 4, Sterilization pool 5, secondary settling tank 6 are sequentially connected；The flocculation basin 1, the settling tank 4 and the secondary settling tank 6 respectively with institute State the connection of silt basin 7.

Sewage is first passed around into grid pond 1, primary filtration is completed using flase floor in grid pond 1, by the solidification in sewage Object is isolated, and avoids blocking subsequent pipeline；Then after filtering in liquid injection flocculation basin 2, flocculant is added into sewage, such as The mixture that high molecular polymer, lime and water are constituted, occurs flocculation in flocculation basin 2, colloid in sewage and tiny Suspended matter etc. is gathered into the floccule body with separable characteristic and sedimentation；Upper clear supernate is sent into conditioning tank 3 by entering pipeline, passes through Regulator tank 31 adds reagent to conditioning tank 3 and a degree of chemical reaction, partial material shape occurs such as pH reagent, oxidant At sediment, settling tank 4 is sent into mixed material export, and sediment settles down successively；The clear liquid of top injects sterilization pool 5 In；Blender 51 is provided on sterilization pool 5, bottom is equipped with aeration tube 52, and aeration tube 52 is connected to external chlorinating machine, quite In injecting chlorine into sewage, chlorine can be overflowed from the stomata on aeration tube 52 and be entered in sewage, at the same time, stir It mixes device 51 and plays the role of stirring-up sewage, so as to accelerate the dissolution of chlorine, and then improve Disinfection Effect and efficiency；Disinfection Sewage afterwards is sent into secondary settling tank 6 and carries out subsiding and purifying processing again.

For the mud that flocculation basin 1, settling tank 4 and secondary settling tank 6 generate, mud directly is delivered to through spiral propeller Pond 7, can further filtration drying, be such as dehydrated by filter press 8, the sewage of generation is back to the processing of flocculation basin 2, solid material It is dry, fertilizer is made.

Tthe utility model system combines design using flocculation, adjusting and multistep sedimentation, handles sewage, treatment effeciency Height, good sewage processing effect, effluent quality is good, low energy consumption, processing capacity is big.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
