Description
Technical field
The present invention relates to a kind of water treating equipment, especially a kind of cross-flow air floatation device, specifically a kind of cross-flow air floatation device with secondary filtration.
Background technology
As everyone knows, the air-flotation type water treating equipment are equipment commonly used in all kinds of water technologies, and as shown in Figure 1, it is comparatively desirable for the purification of water quality of suspended substance proportion about 1.
The air-float water treatment facility mainly is by pressure water and pressure air, in molten cylinder, fully mix, suddenly decompression discharges again, in air-flotation reactor, discharge countless tiny bubbles, bubble can be adsorbed in uphill process on suspended substance or the oils, make it volume and increase and float, regularly remove by slag scraper, all the other relatively water of cleaning collect by the collecting chamber bottom.
Improve the suspended substance removal effect in order to rise to; usually also need to when water inlet, add medicament (flocculation agent) and form alumen ustum; air supporting relies on bubble absorption to reach the purpose that purifies water; but there are a large amount of bubbles to vanish voluntarily mobile the reaching in bubble rising, the stop process of water inlet; therefore having a lot of proportions to be a bit larger tham 1 suspended substance can descend gradually because of bubble-break; form secondary settlement; affect effluent quality; this problem has restricted the performance of airfloat equipment usefulness; thereby airfloat equipment is commonly used for pre-treatment or middle-chain at present domestic, and non-terminal equipment.
Summary of the invention
The objective of the invention is in the bubble uphill process, can cause proportion to be slightly larger than 1 suspended substance realization secondary settlement for existing cross-flow air floatation device because bubble breaks, affect the problem of effluent characteristics, design a kind of cross-flow air floatation device with secondary filtration.
Technical scheme of the present invention is:
A kind of cross-flow air floatation device with secondary filtration, it comprises air flotation pool 8, air flotation pool 8 is air-flotation reactor 9 by the baffle for separating of installing in the pond, collecting chamber 10 and clean water chamber 11, air-flotation reactor 9 is connected with water-in 1 and dissolved air water import 2, dissolved air water import 2 is connected with the outlet of molten cylinder, water-in 1 is connected with chemicals dosing plant, the bottom of collecting chamber 10 is equipped with perforation header 3, the bottom that it is characterized in that described clean water chamber 11 is equipped with porous plate 12, drain cap 13 is installed on the prosopyle of porous plate 12, filtering layer 7 is installed on the porous plate 12, the water side of described perforation header 3 is passed dividing plate and is stretched into and be upward through the top that filtering layer 7 stretches into clean water chamber 11 clean water chamber 11 again from the bottom of collecting chamber 10, the water-in of water shoot 5 is arranged in clean water chamber 11, the bottom of porous plate 12, the water outlet of water shoot 5 are positioned at outside the air flotation pool 8; In clean water chamber 11, the bottom of porous plate 12 is equipped with the discharge hole mouth 14 that has blowdown and back flushing concurrently.
The thickness of described filtering layer 7 is 400-600mm, and the particle diameter of filtrate is 0.6～1.2mm.
Described drain 14 is connected with outlet and the blow-off pipe of molten cylinder respectively by three-way valve.The beneficial effects of the utility model:
The present invention is by making the again process filtering layer through flocculation treatment water carry out secondary filtration, thoroughly which proportion is slightly larger than 1 fall because of the bubble contaminant filter that is deposited in the clear water zone that breaks, for improving effluent characteristics very important effect is arranged, can be used as final water through the water quality after the present invention's processing, this also so that the cross-flow type air-floated water treating apparatus can be used as the terminating unit use, greatly reduces the cost of water treatment complete equipment.
The present invention is simple in structure, is easy to realize, and need not backwashing equipment and can finish back flushing to filtering layer, and it can utilize the sewage draining exit of former usefulness to link to each other with the molten cylinder that produces high pressure water and bubble, utilizes the pressure water of molten cylinder directly to recoil.
Description of drawings
Fig. 1 is the structural representation of existing vertical-flow air flotation device.
Fig. 2 is structural representation of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 2.
A kind of cross-flow air floatation device with secondary filtration, it comprises air flotation pool 8, air flotation pool 8 is air-flotation reactor 9 by the baffle for separating of installing in the pond, collecting chamber 10 and clean water chamber 11, air-flotation reactor 9 is connected with water-in 1 and dissolved air water import 2, the outlet of dissolved air water import 2 and molten cylinder (fully mix irregularly produce a large amount of small bubbles by dissolved air water import 2 in air-flotation reactor 9 afterwards with pressure water and pressure air) is connected, water-in 1 is connected with chemicals dosing plant (structure is identical with existing chemicals dosing plant), the bottom of collecting chamber 10 is equipped with perforation header 3, the top of collecting chamber 10 is equipped with slag scraper 6 and ash pit 4, the bottom of described clean water chamber 11 is equipped with porous plate 12, ABS drain cap 13 is installed on the prosopyle of porous plate 12, filtering layer 7 is installed on the porous plate 12, the thickness of filtering layer 7 is 400-600mm, it is the quartz sand of 0.6～1.2mm that filtrate can adopt particle diameter, the water side of perforation header 3 is passed dividing plate and is stretched into and be upward through the top that filtering layer 7 stretches into clean water chamber 11 clean water chamber 11 again from the bottom of collecting chamber 10, the water-in of water shoot 5 is arranged in clean water chamber 11, the bottom of porous plate 12, the water outlet of water shoot 5 are positioned at outside the air flotation pool 8; In clean water chamber 11, the bottom of porous plate 12 is equipped with the discharge hole mouth 14 that has blowdown and back flushing concurrently, drain 14 is connected with outlet and the blow-off pipe of molten cylinder respectively by three-way valve, when needs carry out back flushing to filtering layer, only need open the road valve that is communicated with molten cylinder and can directly utilize the pressure water in the molten cylinder to carry out back flushing, the water of back flushing can be discharged by ash pit 4.
