In description, the meaning of " plurality " is two or more, unless otherwise specifically defined.
In the present invention unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " Gu
It is fixed " etc. terms shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood as the case may be
Concrete meaning in the present invention.
As depicted in figs. 1 and 2, a kind of water treatment filter pond of the present embodiment, including water purifying tank 20 and filtering ponds 21, water purifying tank
20 height is higher than the height of drainpipe 24.The bottom of filtering ponds 21 is connected to the bottom of water purifying tank 20, in filtering ponds 21 under
It is up successively arranged sieve 22, air inlet pipe 23 and drainpipe 24, water inlet pipe 25, air inlet pipe 23 and draining are equipped with above drainpipe 24
Filter material layer 26 is equipped between pipe 24, filter material layer 26 includes anthracite coal measure, quartz sand layer and the garnet layer being arranged from top to bottom.
The entrance of air inlet pipe 23 is connected to high-pressure air source, and the outlet of air inlet pipe 23 is to offer in air inlet pipe 23 towards filter
The venthole that the bed of material 26 is arranged.Water inlet pipe 25 is equipped with the first valve 27, drainpipe 24 is equipped with the second valve 28, air inlet pipe 23
It is equipped with third valve 29.
In the present embodiment, the quantity of filtering ponds 21 is four, and four filtering ponds 21 are set to the same side of water purifying tank 20, often
A filtering ponds 21 can be independently filtered.Water purifying tank 20 is equipped with discharge outlet, is equipped with drain valve at discharge outlet.
There are two types of operating modes for above-mentioned water treatment filter pond tool, the as single-stage mistake when four filtering ponds 21 are used in parallel
Filter, when the arbitrarily series connection of four filtering ponds 21 is double-filtration.
When single-stage filters, the first valve 27 and drain valve are opened, all the second valve 28 and third valve 29 are closed, into
The waste liquid that water pipe 25 enters effectively removes oil removal by the filter material layer 26 in filtering ponds 21, is then entered by sieve 22 net
Pond 20, and pass through the discharge outlet of water purifying tank 20 discharge treated liquid.
When double-filtration, 1-3 in four filtering ponds 21 are selected as the second fillter section, in the present embodiment, selects 1
A filtering ponds 21 are used as the second fillter section, close drain valve, open the second valve 28 of this filtering ponds 21, close this filtering
First valve 27 and third valve 29 in pond 21；The first valve 27 for opening remaining three filtering ponds 21 closes remaining three mistakes
Second valve 28 and third valve 29 in filter tank 21, waste liquid pass through first after three 21 first times of filtering ponds remove oil removal
Into water purifying tank 20, then enter back into the filtering ponds 21 as the second fillter section, waste liquid from the sieve 22 of this filtering ponds 21 into
Enter, is discharged after removing oil removal for the second time by filter material layer from drainpipe 24.
When filtering ponds 21 need to clean, the first valve 27 of the filtering ponds 21 is closed, opens the second valve 28 and third
Valve 29, compressed air blow to filter material layer by the venthole of air inlet pipe 23, push filter material layer expansion, and sewage is from 24 row of drainpipe
Out.As the water of filtering ponds 21 is discharged, since the water in water purifying tank 20 is in high water level, under liquid level difference impetus, water
The continual pollutant by filter material layer is washed out and is discharged from drainpipe 24.After the completion of cleaning, 28 He of the second valve is closed
Third valve 29, filter material layer sink to restoring, and water level restores normal.
During entire filtering and cleaning, leading portion water treatment system is waited without shutting down, and can still be operated normally,
During cleaning single filtering ponds, other filtering ponds can be operated normally.
The utility model is not limited to above-mentioned optional embodiment, anyone can obtain under the enlightenment of the utility model
Other various forms of products, however, making any variation in its shape or structure, all the utility model rights that falls into are wanted
The technical solution in confining spectrum is sought, is all fallen within the protection scope of the utility model.
