Description
Technical field
The utility model belongs to field of sewage treatment equipment, is specifically related to a kind of unpowered sewage disposal device.
Background technology
For the water quality requirement making sewage reach a certain water body of draining or reuse, and to the process that it purifies.Sewage disposal is widely used in building, agricultural, and the every field such as traffic, the energy, petrochemical industry, environmental protection, urban look, medical treatment, food and drink, also come into the daily life of common people more and more.
Surface water pollution is apparent, and the pollution of underground water is but startling.In China's 1,300,000,000 populations, there is 70% Drinking Water, in more than 660 city, have more than 400 city to take underground water as drinking water source.But it is introduced, the urban groundwater in the whole nation 90% is polluted.
Water pollutions situation is constantly aggravated, and make sewage disposal and regeneration industry receive unprecedented concern, within nearly 2 years, each department rate of gross profit all remains on about 70%, and the area even had has exceeded 100%, and industry development potentiality are very large.
Existing sewage disposal mostly adopts the mode of Sewage Plant process, and operating cost is high, is not suitable for some midget plants and uses.Therefore, the treatment facility designing a kind of applicable small displacement sewage is needed.
Utility model content
The utility model object is to provide a kind of unpowered sewage disposal device, and solve the mode that existing sewage disposal mostly adopts Sewage Plant process, operating cost is high, is not suitable for some midget plants and uses.
The technical solution of the utility model is: a kind of unpowered sewage disposal device, comprise single filter case and cascade filtration case, described single filter case side is provided with sewage inlet, single filter box top is provided with one-level outlet of sewer, impurities removal door is had bottom single filter case, screen pack is provided with in single filter case, screen pack is arranged between sewage inlet and one-level outlet of sewer, cascade filtration box top is provided with B-grade sewage entrance, one-level outlet of sewer is connected by tube connector with B-grade sewage entrance, the row's of being provided with silt mouth bottom cascade filtration case, fine filter is provided with in cascade filtration case, cascade filtration case sidewall is provided with pure water inlet, pure water inlet is arranged between fine filter and row's silt mouth.
Further, the mesh aperture of described screen pack is 0.5-2cm.
Further, described fine filter is asymmetrical fibre filter.
One-level outlet of sewer higher than sewage inlet, and arranges screen pack between one-level outlet of sewer and sewage inlet, and floating thing can be filtered net effectively interception, due to Action of Gravity Field, can reduce the blocked situation of screen pack and occur.
The mesh aperture of screen pack is 0.5-2cm, can effectively filter most floating impurity.
Fine filter adopts asymmetrical fibre filter, has that filtering velocity is fast, holding filth capacity large, the advantage of easily backwash.
The utility model compared with prior art tool has the following advantages:
Multistage filtering sewage disposal device of the present utility model is unpowered operation, easy to maintenance, has operating cost low, stable feature, and treating capacity is moderate, is particularly suitable for small displacement sewage disposal and uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, Reference numeral is: 1-sewage inlet, 2-single filter case, 3-screen pack, 4-impurities removal door, 5-tube connector, 6-cascade filtration case, 7-fine filter, 8-pure water inlet, and 9-arranges silt mouth.
Detailed description of the invention
Embodiment 1
A kind of unpowered sewage disposal device, comprises single filter case 2 and cascade filtration case 6.Described single filter case 2 side is provided with sewage inlet 1, and single filter case 2 top is provided with one-level outlet of sewer, has impurities removal door 4 bottom single filter case 2, regularly can open impurities removal door 4 and remove the large impurity filtered.Be provided with screen pack 3 in single filter case 2, the aperture of screen pack 3 is 0.5cm, and screen pack 3 is arranged between sewage inlet 1 and one-level outlet of sewer.Cascade filtration case 6 top is provided with B-grade sewage entrance, one-level outlet of sewer is connected by tube connector 5 with B-grade sewage entrance, the row's of being provided with silt mouth 9 bottom cascade filtration case 6, fine filter 7 is provided with in cascade filtration case 6, cascade filtration case 6 sidewall is provided with pure water inlet 8, and pure water inlet 8 is arranged between fine filter 7 and row's silt mouth 9.
Embodiment 2
A kind of unpowered sewage disposal device, comprises single filter case 2 and cascade filtration case 6.Described single filter case 2 side is provided with sewage inlet 1, and single filter case 2 top is provided with one-level outlet of sewer, has impurities removal door 4 bottom single filter case 2, regularly can open impurities removal door 4 and remove the large impurity filtered.Be provided with screen pack 3 in single filter case 2, the aperture of screen pack 3 is 2cm, and screen pack 3 is arranged between sewage inlet 1 and one-level outlet of sewer.Cascade filtration case 6 top is provided with B-grade sewage entrance, one-level outlet of sewer is connected by tube connector 5 with B-grade sewage entrance, the row's of being provided with silt mouth 9 bottom cascade filtration case 6, fine filter 7 is provided with in cascade filtration case 6, cascade filtration case 6 sidewall is provided with pure water inlet 8, and pure water inlet 8 is arranged between fine filter 7 and row's silt mouth 9.Described fine filter is asymmetrical fibre filter.Asymmetrical fibre metre filter precision is high, can more than 95% be reached to the clearance of suspension in water, have certain removal effect, through the processed water of good coagulating treatment to impurity such as larger molecular organics, virus, bacterium, colloid, iron, when water inlet is for 10NTU, below water outlet 1NTU; The rate of filtration is fast: be generally 40m/h, reaches as high as 60m/h, is more than 3 times of normal sands filter; Pollutant holding capability is large: be generally 15 ~ 35kg/m3, is more than 4 times of normal sands filter; Backwash water consumption rate is low: backwash water consumption is less than 1 ~ 2% of cycle drainage amount.
