Description
Technical field
This utility model relates to sewage treatment area, particularly relates to a kind of air supporting and becomes the filter of hole filtering pool combined air flotation
Pond.
Background technology
Along with reservoir and river seedbed pollution of waterhead problem become increasingly conspicuous, wherein algae pollution is particularly acute, for water
The operation of factory and water supply security cause certain threat.The density of algae is little, and traditional precipitation solid-liquid separation process is very difficult to be had
Effect is removed, and brings the series of problems such as filter tank blocking, backwashing period shortens, processing cost increases, effluent quality variation, some
Algae the most also can produce Algae toxins, threatens water supply security.
The air-float filtration technique generally used, general flotation tank and filtering ponds are single facility, and two facilities are individually built
If.Last century, the nineties, once had air supporting to be connected with movable Hood Filter, shares district to be filtered and gets rid of scum silica frost equipment.But by
In the deficiency of movable Hood Filter itself, oneself removes in new criteria.
The conventional air supporting used at present and filtration facility, individually build, and its floor space is big, investment cost is high, operation
Complex management.For the water factory that land used is nervous, it is impossible to meet requirement.
Summary of the invention
This utility model seeks to solve deficiencies of the prior art, it is provided that one is by air supporting and change hole filtering pool
Both are organically combined by the organic structures combined, and utilize space, save occupation of land, reduction investment, minimizing equipment, concentration
Management, has the advantages such as technical advance, the suitability and economic rationality.
For reaching above-mentioned purpose, air supporting of the present utility model with become hole filtering pool combined air flotation filter tank, comprising: contact area and
Becoming hole filtering pool, wherein, described contact area is the contact area of water inlet and dissolved air water, and bottom is provided with water inlet pipe, dissolved air water water inlet
Pipe and backwash drain pipe；Become hole filtering pool to include: district to be filtered, filtering area and water and air distributing district, district to be filtered is pneumatically supported solid-liquid
Disengagement zone, its top is provided with running vehicle type Slag Scraping Device, and side is provided with scum trough；Described filtering area is positioned at the lower section in this district to be filtered；
Described water and air distributing district is positioned at the lower section of this filtering area.
It is also preferred that the left described filtering area is quartz sand filter media and cobble bed course from top to bottom.
It is also preferred that the left described water and air distributing district uses filter plate and strainer head.
It is also preferred that the left backwash drain pipe port described in slope aspect bottom described contact area.
It is also preferred that the left described water and air distributing district is provided with outlet pipe, backwash water inlet pipe and backwash air inlet pipe.
It is also preferred that the left this Airfloat filtering pond is double layout, often drain into few 2 lattice, flotation tank supporting with filter tank become 4 groups, supporting 4
Dissolving, shares 1 set air supply system.
This utility model difference from prior art is that this utility model achieves following technique effect:
(1) make flotation tank organically combine with becoming hole filtering pool, two cell body are merged into one, saves floor space；
(2) air-flotation system equipment organic linking, shares coagulation and air supply system, reduces number of devices；
(3) civil engineering and equipment investment are reduced；
(4) equipment is concentrated, it is simple to operational management.
Below in conjunction with the accompanying drawings this utility model is described further.

Detailed description of the invention
Below in conjunction with embodiment, to this utility model, above-mentioned and other technical characteristic and advantage are made in more detail
Bright.
Refer to Fig. 1 and Fig. 2, in an embodiment, air supporting of the present utility model and change hole filtering pool combined air flotation filter tank, bag
Include contact area 1 and become hole filtering pool.Wherein, become hole filtering pool and include district 2 to be filtered, filtering area and water and air distributing district.
Become hole filtering pool and be provided with piping lane and single coagulating treatment unit, can be arranged on according to water factory's land use situation and connect
Touch above district or become hole filtering pool side and build jointly with becoming hole filtering pool.Contact area 1 is i.e. as becoming the inlet channel of hole filtering pool, molten gas
Water and water inlet contact area, also serve as the drainage ditch of backwash water；The district to be filtered 2 becoming hole filtering pool is solid-liquid displacement zone, solid-liquid separation
Top, district arranges running vehicle type Slag Scraping Device, and side sets scum trough 3.Bottom, solid-liquid displacement zone is set to filtering area 5, and filtering area arranges two
Plant the variable orifice gap filtrate that quartz sand filter media is formed.3 layers of cobble bed course 4 are set below quartz sand filter media.For water distribution below filtering area
Distribution district 6, uses filter plate and strainer head water and air distributing, and outlet pipe, backwash water inlet pipe and backwash air inlet pipe are arranged on and join
Water distribution district 6.This utility model uses flood level to filter, and compresses scum silica frost by Slag Scraping Device, is compressed by scum silica frost, improves and gets rid of scum silica frost
Concentration.
Water inlet, after coagulation, enters into contact area through water inlet pipe 7, and dissolved air water is entered by dissolved air water water inlet pipe 9
Contact with water inlet to contact area 1, behind contact area 1, enter district to be filtered, variable orifice gap filter tank 2, i.e. solid-liquid displacement zone carry out solid
Liquid separates, and after scum silica frost uses Slag Scraping Device that scum silica frost is linked into scum trough, discharges through floating scum pipe 12.Water inlet is through quartz sand filter media
With cobble bed course filter after enter water and air distributing district 6, after through outlet pipe 13 draining.Backwash row is set bottom contact area 1
Water pipe 8.Backwash is intake through backwash water inlet pipe 10, and back suction air inlet enters water and air distributing district through backwash air inlet pipe 11, passes through
Carrying out backwash for filtrate after strainer head water and air distributing distributed uniform, backwash is drained into behind contact area 1 through backwash
Drain pipe 8 is got rid of, and for ease of draining, the bottom slope aspect backwash drain pipe port of contact area 1 is arranged (i.e. towards backwash drain pipe port
Downward-sloping).
In this embodiment, Airfloat filtering pond is double layout, often arranges 2 lattice, flotation tank supporting with filter tank become 4 groups, supporting 4 molten
Gas tank, shares 1 set air supply system；Further, this Airfloat filtering pond uses constant water level filtering, and water-in and water-out valve in filter tank uses automatic valve
Door.
Embodiment described above is only to be described preferred implementation of the present utility model, not to this practicality
Novel scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various deformation that the technical scheme of utility model is made and improvement, all should fall into the protection that this utility model claims determine
In the range of.
