Abstract
The utility model relates to a filtering basin with low water consumption in washing, which mainly comprises a backwashing pipe, a backwashing valve, a basin body, a water inlet, a filtering material support member, a filtering material, a water outlet, a water outlet valve, a sludge discharge hole and a sludge discharge valve, wherein the filtering material support member and the filtering material are combined to form a filtering unit; the filtering unit is arranged in the water of the filtering basin; the filtering unit is connected with the backwashing pipe and the water outlet pipe; and the filtering unit is of a structure of which the lower part is thin and the upper part is thick. When filtering is carried out, water to be filtered enters into the filtering unit through the filtering material from outside to inside, and then is discharged from the water outlet; as the filtering unit has the thin lower part and the thick upper part, suspended matter retained on the filtering material can be separated from the bottom of a filtering material sedimentation basin under the action of gravity after being accumulated to a certain extent, and thus, the backwashing frequencies can be reduced; when backwashing needs to be carried out, the water outlet valve is turned off, and the backwashing valve is opened; backwashing sludge directly enters into the filtering basin without discharging; the sludge in backwashing water is deposited to the bottom of the filtering basin. The filtering basin has fewer backwashing frequencies and does not need to discharge a large amount of backwashing water, and therefore, the filtering basin has an obvious water-saving effect.
Description
Technical field
The utility model relates to a kind of filtering ponds, the few filtering ponds of especially a kind of backwash water consumption.
Background technology
At present, there are two classes in most widely used filter tank, and a class is the granule medium filtering ponds, belongs to deep-bed filtration, as common quartz sand filter media filter tank, multilayer filter material filter pool, fibre filter, not a kind of be both surface filtration filter tank, the most typical state-of-the-art outer water inlet type rotary turnplate filter cloth filter tank that is.The granule medium filter is effective, but floor space is big, the operational management complexity, and the loss of flood peak is big, the backwash water consumption is very big, is generally the 5-7% that filters the water yield.The filter tank loss of flood peak of fibre turntable filter cloth is little, the backwash water consumption is lacked than the granule medium filtering ponds, be generally 2-3%, floor space is less, but the backwash water consumption is still bigger than normal, above-mentioned filter tank also have a common deficiency place be exactly filter cycle all shorter, anti-time number of times is more, especially rotary turnplate filter cloth filter tank, its filter cycle is shorter, generally has only 2-4 hour, discharge a large amount of backwash water, cause the waste of water.
The utility model content
This overcome the deficiency that the backwash number of times is more, the backwash water consumption is big that existing filtering ponds exist, the utility model provides a kind of backwash water consumption few water-saving filtering ponds, it has not only significantly reduced the backwash number of times, prolonged filter cycle, and do not need to discharge a large amount of backwash water, water-saving result is remarkable, thereby also energy-conservation.Moreover, if the filtrate filter cloth, the utility model also possesses whole advantages in fibre turntable filter cloth filter tank, if the employing granule medium is done filtrate the utility model then also had the advantage in granule medium filter tank.
The technical scheme that its technical problem that solves the utility model adopts is: the filtering ponds that this cleaning water consumption is few, mainly form by backwash tube, backwash valve, pond body, water inlet, filter element, delivery port, outlet valve, mud discharging mouth, mud valve, filter element is made of filtrate support member and filtrate, it is characterized in that filter element places filter tank water in the body of filtering ponds pond, filter element connects backwash tube and delivery port, and filter element is the structural shape that the bottom is thin, top is thick.Its water inlet of filtering ponds that this cleaning water consumption is few links to each other with filtering ponds pond body with mud discharging mouth, install backwash valve on the backwash tube, delivery port connects outlet valve, in the body of filtering ponds pond a plurality of filter elements can be installed, can install rapping apparatus on filter element, the backwash medium that is used for the few filtering ponds of this cleaning water consumption can also can be used liquid with gas.During filtration, treat that drainage is entered in the body of pond by water inlet, then, enter in the filter element after the filtrate by filter element filters from outside to inside that the water after the filtration flows out via delivery port under gravity (head) effect.Along with filtration is carried out, filtering material resistance increases, when water level rises to designated water level in the body of pond, carry out backwash, can close water intaking valve and outlet valve this moment, open backwash valve, the backwash medium enters filter element inside by backwash tube and from inside to outside filtrate is carried out back flush, and the backwash medium can also can be used liquid with gas; Backwash is gone out filtrate with cutting out the suspension mud that stays in the filtrate, enters in the body of pond, and after the knot speed subject to backwash, after sedimentation a period of time, suspension mud sinks to body bottom, pond, closes backwash valve, opens water intaking valve and outlet valve, then carries out filter process again.According to the influent quality situation, regularly or irregularly open mud valve and carry out spoil disposal.
Because filter element is for carefully going up thick structural shape down, when the suspension mud that filtrate is held back when filtering was more and more, weight increased, and has part suspension mud and break away from and at the bottom of sinking to the pond from filtrate under the gravity effect, so just can significantly reduce the backwash number of times, reduce the backwash displacement.In addition, can on filter element, install rapping apparatus, can quicken the disengaging of suspension mud, help prolonging filter cycle, reduce the backwash number of times.Since after the backwash in filtrate the suspension mud of wash-out be to discharge after at the bottom of being deposited to the pond, mud obtains gravity and concentrates, the sludge concentration height, so the spoil disposal number of times significantly reduces, sludge volume significantly reduces, than other filter types and filtering ponds, the backwash sludge volume of the filtering ponds that the cleaning water consumption of the utility model is few significantly reduces, mean that cleaning water consumption significantly reduces, generally only account for the 0.6-1% that filters the water yield, water-saving result is very obvious.The few filtering ponds of cleaning water consumption of the utility model, its backwash mode also can adopt at filter material surface or press close to the mode that filter material surface is installed the back suction device, are to strengthen backwash effect, the mode that also can adopt backwash and back suction The combined to use.The few filtering ponds of cleaning water consumption of the utility model can be installed one or more filter elements in the body of pond, depend on actual need and decide.
