Description
Technical field
This utility model relates to a kind of filter backwash apparatus for recovering, belongs to water-treatment technology field.
Background technology
The precipitation of circulating water treatment fIthy circulating system and clarifying process, the bigger solid particle of a part in water or easily sink
The magazine formed sediment is removed.But to make Water warfare further, the method that filtration must be utilized, by installing filter, make water lead to
After filter material filtering layer, the fine particle impurity in water is retained down, so that water is further clarified and purifies, water
Turbidity reduce again.Filtration can also make the organic substance in water, antibacterial, virus etc. along with the reduction of turbidity and quilt
A large amount of removals, and create good condition for the sterilization after filter.Filter through normal filter the working cycle after, filtering layer filtrate
On retained substantial amounts of dirt, filter capacity declines.At this moment, it is necessary to filter is carried out or backwash, to recover to filter
The filter capacity of device.The water quality of filter backwash water is very poor, therefore can not enter system, otherwise affect water supply quality, Jin Erying
Ring consumer products quality；Meanwhile, if backwash water is all drained, system water loss is too big, causes rate of water make-up, medicament magnitude of recruitment
Big Deng consuming.(backwash water water quality and system normal water supply water-quality ratio are relatively shown in Tables 1 and 2)
Table 1: the main water quality of normal operational cycle water system water supply
Table 2: filter backwash water water quality
In view of the foregoing, filter backwash water must be further processed, to reach the effect of reuse.Traditional
Technique processing method is backwash water to be entered dedusting pond or horizontal flow basin recycles.But for system dust removing pond or advection
The pumping plant that tankage is little, if taking the method directly reclaimed, will result in system water pollution, and water treatment is defective just to supply
Occur to the phenomenon of user.
Utility model content

Bottom is arranged, and filter cloth is fixed on the top of column.Fig. 3 is backwash recovery pond device internal cross section figure.
The volume of described recovery pond determines according to the separate unit filter backwash water water yield and time, be set as 1.5m × 1.5m ×
2m specification.This utility model is other fabrication and installation cement backwash recovery pond in former dedusting pond, and the volume of recovery pond filters according to separate unit
The device backwash water water yield and time determine.The existing filter separate unit backwash water yield is 80m3/ h, the backwash time is 20 minutes, so, one
The secondary separate unit filter backwash water yield is 27 m3/ h, the backwash water time of staying in pond is 1-3 minute, it is considered to inner structural members
The factor such as installation, cement recovery pond is made as 1.5m × 1.5m × 2m specification.
Described recovery pond 8 connects with dedusting pond 4, and the two is the most standby.When recovery pond overhauls or under failure condition, not shadow
Ring filter backwash normally to work, by control valve, make backwash water enter dedusting pond, then regulated by backwash water flowing water Valve
With extend the mode such as backwash time, make backwash water recycle on the premise of not affecting water supply quality.
Concrete operation method is: select the cement of position fabrication and installation 1.5m × 1.5m × 2m specification on side, dedusting pond
Pond, pond internal production disc type steel pipe, perforate on steel pipe, it is placed in bottom pond；The corresponding supporting construction of filter cloth is installed simultaneously, will
Filter cloth is fixed.At pond top drilling DN125mm, access filter backwash outlet pipe DN100mm, and install DN100mm valve additional
V1, installs DN100mm outlet pipe, installs valve V2 additional, access dedusting pond bottom pond.Meanwhile, the outside DN20mm of access compresses sky
Trachea and internal coil pipe connect, and install control valve DN20 mmV3 additional.The caliber of bottom disc type steel pipe is 50mm, disc type steel pipe
Cylindrical be 1000mm, disc type steel pipe is evenly arranged with the aperture that aperture is 6mm.
Operation method is as follows: time 1, properly functioning, closes former dedusting pond valve V, opens recovery pond intake gate V1 filter
Backwash water enters recovery pond, enters the reuse of dedusting pond by filtering layer filter cloth after being processed.
2, run after certain time, by detection recovery pond effluent quality and the water yield, as do not reach water supply quality standard and
The recovery pond water outlet water yield, needs recovery pond filtering layer filter cloth is carried out or is changed.Now, close recovery pond inlet valve V1,
Open dedusting pond backwash water valve V, open compressed air inlet valve V3, be carried out.If cleaning thorough, filter cloth is removed into
After row individually cleans or changes, put into recovery pond and run.
If 3 recovery pond internal structures are damaged needs maintenance, close recovery pond inlet valve V1, open dedusting pond backwash water
Valve V runs.In this mode is run, need adjust the backwash water water yield and extend the backwash time, to guarantee that backwash water will not be dashed forward
So contaminated system, the system that affects normally produces.
Table 3: filter backwash water effluent quality after focusing on
As can be seen from Table 3, the result after this utility model is on probation disclosure satisfy that Production requirement.
