The process is technologically advanced, applicable and economically rational.

Description

Air flotation pool and combination pond, V-type filter tank

Technical field

The utility model relates to the purified water treatment device technical field, is a kind of air flotation pool and V-type filter tank combination pond specifically.

Background technology

Middle-size and small-size water purification plant often adopts air supporting and filtration facility in handling low temperature and low turbidity water, micro-polluted water technology, generally all be self-organizing system, and two structures are separately built separately.Generally adopted in air-water backwashing V-type filter tank in recent years, and last century, the nineties once had air supporting to be connected with the mobile cover filter tank, shared filter district and the eliminating scum silica frost equipment treated.But after twentyth century, because the deficiency in mobile cover filter tank itself removes in new criteria, using very fewly, is air-water backwashing V-type filter tank and use more recently.

Summary of the invention

The utility model will solve the prior art above shortcomings exactly, a kind of integrated structures that air supporting is combined with the V-type filter tank are provided, both are organically combined, utilize space, shared source of the gas, saving occupation of land, minimizing equipment, management to concentrate, the air-float filtration technology of middle-size and small-size water purification plant is had a kind of air flotation pool and the combination pond, V-type filter tank of its technical advance, suitability and economic rationality.

Technical problem of the present utility model adopts following technical proposals to solve:

A kind of air flotation pool and combination pond, V-type filter tank, comprise air flotation pool, V-type filter tank and flotation separation zone, top, V-type filter tank is provided with piping lane, and piping lane top is provided with inlet channel, crosses mill weir, bypass channel, described air flotation pool is connected with the V-type filter tank, and the V-type filter tank is treated that the filter district is as the flotation separation zone; The vertical direction spatial of the inlet channel on piping lane top, V-type filter tank, mistake mill weir, bypass channel and bottom is as the air supporting zone of action of air flotation pool; Bottom, air supporting zone of action is provided with dissolved air release and perforation water distributing pipe, and the perforation water distributing pipe is connected with described V-type filter tank inlet channel; Tube corridor, V-type filter tank one upper lateral part is opened a prosopyle, and the prosopyle feeds in the flotation separation zone, and the V-type filter tank does not have piping lane one upper lateral part and opens row's scum silica frost hole, and row's scum silica frost hole feeds and is located in row's scum silica frost pipeline of outside, V-type filter tank, and the position in row's scum silica frost hole is higher than the prosopyle.

Described filter tank lattice number is at least 4 lattice, becomes 4 groups with air flotation pool is supporting, and every group is connected with dissolving.

The utlity model has following beneficial effect:

1, solve organic connection of two process procedures, shared source of the gas, saving one cover pneumatic compression devices, management are concentrated.

2, two structures are integrated, save and take up an area of, reduce building volume.

3, for middle-size and small-size water factory, with the Airfloat filtering pond that air flotation pool and V-type filter tank are integrated, than two cover systems of building air flotation pool, V-type filter tank separately separately, construction investment can be saved more than 40%, and cost of equipment can be economized about 30%.

Embodiment

Below in conjunction with accompanying drawing the utility model is further elaborated:

The utility model is connected air flotation pool with the V-type filter tank, the filter for the treatment of in V-type filter tank 6 is distinguished as flotation separation zone 5; The vertical direction spatial of utilize piping lane top, V-type filter tank and inlet channel, crossing mill weir, bypass channel and bottom is as air supporting zone of

action

3, and 3 bottoms, air supporting zone of action are provided with dissolved air release 4 and perforation water distributing pipe 2, and perforation water distributing pipe 2 is connected with described V-type filter tank inlet channel 1.The utility model adopts constant water level filtering, change former water intake mode, 6 tube corridors, 7 one upper lateral parts are opened a prosopyle 15 in the V-type filter tank, prosopyle 15 feeds in the flotation separation zone 3, V-type filter tank 6 no piping lane one upper lateral parts are opened row's scum silica frost hole 16, and row's scum silica frost hole 16 feeds and is located in row's scum silica frost pipeline 12 of 6 outsides, V-type filter tank.The position in row's scum silica frost hole 16 is higher than prosopyle 15.

When having solved the filter tank operation and having got rid of the contradiction row scum silica frost of scum silica frost, suitably raise and treat filter district water level, scum silica frost is discharged scum silica frost by mud hole 16; In the row's of entering scum silica frost pipeline 12, saved the scum silica frost residue extraction machine.

Filter tank of the present utility model lattice number is at least 4 lattice, and air flotation pool is consistent with the filter tank lattice, and 4 lattice are got by middle-size and small-size water factory, becomes 4 groups with air flotation pool is supporting, also can reduce the lattice number according to water factory's scale, practical operation situation.Every group is connected with dissolving 10, shared source of the gas, and grouping is provided with dissolving 10, saves a cover pneumatic compression devices.

Workflow: water enters perforation water distributing pipe 2 from inlet channel 1, through the fused air supporting zone of action 3 that enters of dissolved air release 4 and water inlet, the fused body of air water 15 enters flotation separation zone (being that filtered water section is treated in the filter tank) from the prosopyle, and the raising of water level scum silica frost is discharged by mud hole 16 during row's scum silica frost.

For guaranteeing the convenience of constant water level filtering and eliminating scum silica frost, should adopt automatic control (flow) valve and water level gauge.
