Abstract

The invention discloses a novel drinking water processing filter, which belongs to water-treating equipments. The invention mainly comprises a tank, wherein an overflow lip is arranged on the top portion of the tank, a supporting feet is arranged on the lower portion of the tank, a water inlet tube is arranged on the upper portion of the tank, a water outlet and an air inlet are arranged on the upper portion of the tank, filtering materials are arranged on the upper portion of the supporting layer in the tank, a backflush drainage valve which is communicated with the tank is positioned on the upper portion of the material filtering layer, a plurality of arch tubes are arranged on a filter plate, and an air distributing tube, a water distributing tube and an air gas room are arranged in the arch tubes. The invention adopts a double layer filter, which increases the quality of water which is processed, and the invention utilizes the combination of gas and water to wash the material filtering layer through gas and water distribution assembly of the arch tubes which are arranged, water consumption for washing the material filtering layer is reduced, and the spillage of the filter material is reduced.

Description

Novel drinking water treatment filter
Technical field
The present invention relates to a kind of novel drinking water treatment filter that is used to purify waste water.
Background technology
The Drinking Water water purifier has obtained in the rural area using widely, the water quality instability of traditional water purifier discharge water will consume great amount of water resources to the flushing of filtrate, and filtrate often has loss, it is low to hold dirty ability, can not satisfy to the requirement of using the drinking water that safety, high-quality all are provided.
Summary of the invention
It is good to the purpose of this invention is to provide a kind of effluent quality, and washing water quantity is few, and the filtrate turnover rate is low, and it is strong to hold dirty ability, the novel drinking water treatment filter that floor space is little, easy to install.
The object of the present invention is achieved like this: a kind of novel drinking water treatment filter, it is characterized in that: comprise tank body 12, the top is provided with overfall 2, tank body 12 bottoms are provided with leg 15, it is characterized in that: tank body 12 tops are provided with water inlet pipe 4, the bottom is provided with delivery port 16 and air inlet 17, filtrate places the supporting layer top in the tank body 12, filter plate 7 is provided with a plurality of arch tubes 6, be provided with gas distribution pipe 8, water distributor 9 gentle hydroeciums 14 in the arch tube 6, arch tube 6 is provided with exhaust hole, air distribution hole and distributing hole.Be provided with helper 1 inside and outside the tank body 12.Also be provided with liquid level gauge 3 and observation window 11 on the tank body 12.
Novel drinking water treatment filter provided by the present invention, adopt double-bed filter, improved the quality of water after handling and utilized the aqueous vapor cooperation to wash, reduced the water consumption of the flushing worry bed of material, reduced and considered the loss of expecting considering the bed of material by the arch tube air distribution and water distribution assembly that is provided with.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is Figure 1A-A place cutaway view.
Fig. 3 is that Fig. 1 K is to view.
Fig. 4 is an arch tube stereogram of the present invention.
Fig. 5 is an arch tube cutaway view of the present invention.
The specific embodiment
Important technological parameters of the present invention is as follows:
1, the rate of filtration: intake pool turbidity≤20NTU, filtering velocity 12m/h.
2, thickness of filter bed: 1.5m.It is the thick 0.7m of light ceramic at the middle and upper levels, particle diameter 1.6~2.5mm; The thick 0.8m of lower floor's quartz sand, particle diameter 0.7~1.2mm.Supporting layer adopts gravel, thickness 0.42m, particle diameter 3-12mm.Filter material layer headwater depth 1.6m.
3, water head loss by filtration and filter cycle: water head loss by filtration 2.0m; Filter cycle>36h.
4, back washing strength and recoil last: a) gas flushing gas is crossed 17L/ (Sm towards intensity 2), last 3min.B) gas, water while purge gas are towards intensity 17L/ (Sm 2), water is towards intensity 4L/ (Sm 2), last 3min.C) the water flushing water is towards intensity 16L/ (Sm 2), last 1min.D) with after the aforementioned backwashing sewage water discharging, water flushing again.Water is towards intensity 16L/ (Sm 2), last 1min.
5, backwash head: 4.5m.
Operation principle of the present invention is as follows:
Treat that (turbidity≤20NTU) evenly flow into tank body 12 by water inlet pipe 4, water passes filtering layer with gravity leakage and imports the air water chamber drainage, then flows into clear water reserviors.When filter back washing, close inlet valve earlier, press gas flushing, air water flushing, 3 corresponding valves of stage switch of water flushing then; Repeat to close recoil draining butterfly valve after the water flushing once, return to the normal filtration working condition.
2, the course of work
1) normal filtration
Open water intaking valve, treat that (turbidity≤20NTU) enters filter to drainage, and passes filter material layer with gravity leakage; Open outlet valve, the check filtered water reaches the regulation requirement, and filtered water is put into clear water reserviors.
2) backwash
A) close water intaking valve, filter continues to filter.B) when observing water level in the filter in the observation window and reduce on the filter material layer 150mm, close outlet valve.C) drive the backwash intake valve, loosening filter material layer, intensity is 17L/Sm 2, last 3min.D) open little water yield water intaking valve, water is towards intensity 4L/Sm 2Air inlet this moment intensity remains 17L/Sm 2, gas, water wash simultaneously, last 3min.E) close recoil intake valve, little water yield water intaking valve, open a large amount of water intaking valves, water is 16L/Sm towards intensity 2, last 1min.F) close the big yield water intaking valve, behind the static 20s, open the recoil draining valve; Open 45 ° earlier, and then open 90 °.Draining finishes, and closes the recoil draining valve.G) open the big yield water intaking valve, water is towards intensity 16L/Sm 2, last 1min.H) close the big yield water intaking valve, behind the static 20s, open the recoil draining valve: open moving 5 ° earlier, and then open 90 °.After draining is finished, close the recoil draining valve.Flushing process finishes.
