Description
Technical field:
The present invention relates to a kind of air supporting equipment for separating liquid from solid that is used for Drinking Water, municipal wastewater and Industrial Wastewater Treatment.
Background technology:
China's " drinking water sanitary standard " increases to existing 101 by original 88, and wherein the requirement for delivery turbidity rises to existing 1ntu by original 3ntu, and this has proposed challenge to the water technology of existing water factory undoubtedly.Improving the treatment effect of existing water factory conventional treatment process, is one of effective way that addresses this problem.Air-float technology has obtained widespread use as a kind of alternative sedimentary solid-liquid separation process in China.At present there is the problem of the following aspects in it: (1) rule of thumb, the design hydraulic load 5～10m/h of traditional air supporting solid-liquid separation process disengaging zone, in order to guarantee the security of water outlet, the normal hydraulic load that adopts does not also reach 8m/h in the design, and this just makes the floor space of disengaging zone obviously increase.(2) device of removing microbubble is not set in the traditional air-float technology, this makes in the water outlet of air-float technology and contains a large amount of microbubbles, and bubble along with the air supporting water outlet enters in the filter tank phenomenon of filtering layer gas bubble blockage takes place easily, thereby shortens the work period in filter tank.These microbubble surfaces also adhere to a large amount of organism simultaneously, have weakened the air supporting solid-liquid separation process and have removed the effect of little pollution.(3) traditional air-float technology adopts the perforated pipe water outlet, and water outlet is not very even, causes the disengaging zone overall utilization rate not high.
Summary of the invention:
Existing air-floating apparatus hydraulic load is low, floor space big in order to overcome, contain shortcoming such as a large amount of microbubbles in the air supporting water outlet, provide a kind of take up an area of little, efficient is high, the microbubble quantity that contains in the air supporting water outlet is few, the air supporting equipment for separating liquid from solid of water outlet better effects if.The present invention realizes by following proposal: a kind of air supporting equipment for separating liquid from solid, it comprises the rising pipe 5 of air flotation pool 1 and air flotation pool 1 bottom, it also comprises the some risers 2 that equate perpendicular to air flotation pool 1 base plane and spacing, favour the some swash plates 3 of air flotation pool 1 base plane and be parallel to the water collection sheet 4 of air flotation pool 1 base plane, swash plate 3 is set in place between the square thereon riser 2 and the water collection sheet below it 4, be evenly equipped with water hole 4-1 on the surface of water collection sheet 4, water collection sheet 4 is positioned at the top of rising pipe 5 and air flotation pool 1 horizontal direction is blocked.Water flows into air flotation pool 1 from the upper end, because the separation of riser 2 guiding, the waterpower fluidised form is finished by turbulent flow and is tending towards streamlined transformation, and the bubble adhesion in the water is on swash plate 3.Because water collection sheet 4 has substituted traditional tubular type captation, water flows through water collection sheet 4 equably from water hole 4-1, and air flotation pool 1 all is fully used in whole horizontal section, has improved the overall utilization rate of disengaging zone.The present invention realized under the bigger situation of air-float tank waterpower load, air flotation pool disengaging zone waterpower fluidised form by turbulent state to the transformation that is tending towards laminar flow regime, thereby strengthened air flotation pool disengaging zone solid-liquid separation function, improved the water outlet effect.This for delivery turbidity of realizing regulation in existing " drinking water sanitary standard " less than 1ntu require significant.In addition, adopt this novel air supporting equipment for separating liquid from solid, the hydraulic load in the time of can improving the operation of air supporting structures, thus saved floor space.Adopt this technology, the microbubble quantity that contains in the air supporting water outlet is reduced, thereby the air supporting water outlet is entered after the filter tank, the possibility that filtering layer produces gas bubble blockage reduces, and the work period in filter tank prolongs.And, remove the ability of little pollution thereby improved air-float technology owing to removed the microbubble that carries large amount of organic.Adopt captation of the present invention to substitute original perforated pipe, make water outlet more even.According to the difference of the hydraulic load of the different of pending source water quality and design, can adopt the water gathering system of the riser and the different parameters of different spacing.The present invention has reliable operation, reasonable in design and have an advantage of big promotional value.
