Abstract
The invention relates to a water-saving campus laundry. In order to save and sufficiently utilize water resource and protect a natural water body, aimed at the characteristic of low quality of greenbelt irrigation water, the sewage discharged by the campus laundry is directly used for campus greenbelt irrigation after undergoing simple trash blocking, settlement and filtration. The invention further extends the conventional campus laundry, so that the laundry is integrated with campus greenbelt irrigation to form a water-saving campus laundry pattern; after the flows of coarse pollutant blocking by a trash rack, coarse silt filtration by a filtering basin, fine silt settlement by a settling basin and the like, the sewage of the laundry is pressurized by a water pump and then directly enters an irrigation water pipeline, and thereby the direct utilization of the sewage is realized.
Description
Technical field
The present invention relates to laundry, a kind of water-saving campus.
Background technology
School is densely populated living and studying place, and laundry is the living facilities of institution of higher education, vocational school's indispensability especially.Student's sheet, quilt cover, pillow cover and clothing etc. need to utilize the laundry of school to wash.Wash clothes and need to consume a large amount of clean tap water, the colleges and universities of a number of student 20,000, each student clothes washing amount of a year is 50kg, and the clothing of every washing 1kg need to consume 36L water, the water consumption of 1 year laundry is 36000m
3.These water are entered Wastewater Treatment Plant by the sewer pipe that is discharged in vain.Meanwhile, school also has ，Ru meadow, larger area greenery patches, forest land etc. to need to irrigate.One take up an area the colleges and universities of 2000 mu, green area takes up an area 30% and is about 600 mu, the irrigation norm 100m in every mu of greenery patches
3, total irrigation quantity needs 60000m
3.Conventionally the water source of green land irrigation comes from tap water.If the sewage of washing clothes can be processed a little and is directly used in irrigation Campus green space, can save a large amount of tap water, thereby save a large number of water rate for school.Patent of the present invention proposes based on above background just.
The sewage of laundry or enter sewer pipe net, entered afterwards Wastewater Treatment Plant and processed in the past.Sewage after processing is in most cases discharged into natural stream networks; Or directly enter natural stream networks, due to the compound that contains phosphorus in the cleaning solution used of laundry, easily cause the eutrophication of water body, polluted-water.
If washing sewage is entered to natural stream networks through Wastewater Treatment Plant, waste on the one hand a large amount of water resources, increased the weight of on the other hand the cost of sewerage treatment.If directly enter natural stream networks, also can increase the weight of the eutrophication of water body, polluted-water.
Summary of the invention
The present invention relates to laundry, a kind of water-saving campus; in order to save and make full use of water resource; conservation of nature water body, simultaneously for Greenland Irrigation water feature of low quality, the sewage that laundry is discharged is directly used in the irrigation of Campus green space after simply blocking dirt, precipitation, filtration.
1, the present invention further extends traditional laundry, campus, and laundry and Afforestation Irrigation are combined, and forms campus water-saving type clothes washing store schema;
2, laundry sewage is tackled thick pollutant, filtering ponds through trashrack and is filtered thick silt, sedimentation basin and precipitate the thin flow processs such as silt and directly enter irrigation water pipeline after by pump pressurization, realizes the direct utilization of sewage.
Accompanying drawing explanation
By describing in more detail exemplary embodiment of the present invention with reference to accompanying drawing, above and other aspect of the present invention and advantage will become and more be readily clear of, in the accompanying drawings:
Fig. 1 is the composition structural representation of laundry, a kind of water-saving campus of the present invention.
The specific embodiment
Hereinafter, now with reference to accompanying drawing, the present invention is described more fully, various embodiment shown in the drawings.Yet the present invention can implement in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, it will be thorough with completely providing these embodiment to make the disclosure, and scope of the present invention is conveyed to those skilled in the art fully.
Hereinafter, exemplary embodiment of the present invention is described with reference to the accompanying drawings in more detail.
With reference to accompanying drawing 1, described laundry comprises laundry 1, trashrack 2, filtering ponds 3, sedimentation basin 4, pressurization
The thick silt of filter, sedimentation basin precipitate after the thin flow processs such as silt are pressurizeed by pump and directly enter and irrigate use
Waterpipe, realizes the direct utilization of sewage.
The foregoing is only embodiments of the invention, be not limited to the present invention.The present invention can have various suitable changes and variation.All any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., within protection scope of the present invention all should be included in.
Claims (2)
1. a laundry, water-saving campus, is characterized in that:
Described laundry comprises laundry, trashrack, filtering ponds, sedimentation basin, pressure pump, irrigation water pipeline.
2. laundry, a kind of water-saving campus as claimed in claim 1, is characterized in that:
