Description
Technical field
The present invention relates to sewage treatment field more particularly to a kind of new air-floating filters with deslagging function.
Background technique
Ss suspended matter (SuspendedSolids) refers to the solid matter in water of suspending, including insoluble in water inorganic
Object, organic matter and silt particle, clay, microorganism etc..Suspension content is one of the index for measuring water pollution degree in water.Ss suspends
Object is the main reason for causing water muddy.Easy anaerobic fermentation after organic suspended matter deposition in water body, makes water quality deterioration.Using mesh
Preceding water treatment facilities is low to the suspended matter removal efficiency in sewage, effect is poor.
Airfloat filtering pond (DAFF, DissolvedAirFlotationandFiItration) be dissolved air floatation pond (DAF,
DissolvedAirFlotation a kind of) the novel work combined with multimedium filter tank (MMF, Multimedia Filter)
Skill；Airfloat filtering pond top is rectangle dissolved air floatation pond, and lower part is multimedium filter tank, and Airfloat filtering pond can effectively be gone in water removal
Suspended matter.
Bubble sweeps along the particulate matter in sewage to float on the surface in Airfloat filtering pond, needs to utilize slag-scraper by these particulate matters
It scrapes to slag-draining device, however slag-scraper used in Airfloat filtering pond currently on the market is usually to scrape slag by walking dolly drive
Plate, which moves reciprocatingly, scrape slag or mud scraper carries out scraping slag, and such design first: reciprocal operation is easy to keep bubble broken back and forth
Broken, particulate matter can sink again；Second: a kind of slag-scraper is only set in many Airfloat filtering ponds, and flexibility is inadequate, fills when scraping slag
When setting damage or maintenance, Airfloat filtering pond can only be deactivated, and delay production；Third: the Airfloat filtering pond cleaning shoe length of mud scraper is used
Too long, energy consumption is high；Furthermore in most Airfloat filtering ponds between filtrate and filtrate according to the size of filtering material particle diameter from small to large,
Be packed together, centre do not separate, after backwash little particle be easy floating or fall into the gap of bulky grain, influence using.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of scientific structure design, scrape slag
Deslagging effect is good, a kind of new air-floating filter with deslagging function that low energy consumption.
To realize the present invention the following technical schemes are provided:
A kind of new air-floating filter with deslagging function mainly includes pond body, is divided into sedimentation basin and air bearing in the pond body

Area bottom is equipped with dissolved air water water inlet pipe, is uniformly provided with several dissolved air water releases on the dissolved air water water inlet pipe；The filtering area
It is interior to be equipped with several water draining plates with through-hole；Filtrate is equipped between the water draining plate, the bottom of the filtering area is equipped with water outlet and catchments
Pipe and backwash water pipe.
Preferably, the sedimentation basin sidewall bottom is equipped with water inlet, inclined tube is equipped in sedimentation basin, precipitating bottom of pond portion is equipped with
Scum pipe；Sedimentation basin side wall upper part is equipped with overflow launder, and the overflow launder is located above the spray head of Airfloat filtering pond side wall, the spray head
It is connect with water tank.
Preferably, the sprocket wheel and chain are at least arranged 5 groups in air flotation zone, the scum board is arcuation, is each scraped
The 1/5 of of length no more than pond body width of slag plate, the direction of motion of the scum board and the water spraying direction of spray head are identical.
Preferably, the through-hole on the filtering area internal drainage plate is up-small and down-big round table-like, the filtrate at least three
Kind, first layer filtrate is anthracite from top to bottom, second layer filtrate is quartz sand, third layer filtrate is cobble.
Preferably, the air flotation zone side wall is additionally provided with backwash water outlet and dirt-excluding groove, the dirt-excluding groove is V-arrangement, out
Slag chute is located above backwash water outlet.
Usefulness of the present invention:
First: setting sedimentation basin enters back into air bearing filter after filtering out most of flocculate convenient for first precipitating the waste water after flocculation
Treatment effect is improved in pond；
Second: occupied area is small, and dissolved air floatation pond and multimedium filter tank are designed to up-down structure, are effectively reduced land occupation face
Product, has saved entreprise cost；
Third: it is applied widely, it can be not only used for the pretreatment of Treated sewage reusing, it can also be used to which the pretreatment of water engineering also can be used
In the pretreatment of sea water desalination；
4th: slag-scraper drives scum board using spray head, sprocket wheel, and spray head water spray has booster action to water flow, and scum board again will
Bubble is scraped into dirt-excluding groove, and the 1/5 of the of length no more than pond body width of scum board, low energy consumption, while cooperating the effect of spray head, scrapes slag effect
Fruit is good；
5th: when scum board or spray head need to safeguard or overhaul, can individually open one of them, have no effect on entire air bearing
The use in filter tank, without shutting down；
6th: water draining plate being set between filtrate and filtrate in filtering area, through-hole is set on water draining plate, through-hole is up-small and down-big circle
Mesa-shaped；Firstly, the speed that water flow can be delayed to decline when purification；Secondly, it is possible to prevente effectively from little particle filtrate falls into bulky grain
In the gap of filtrate, again, the irrigation flow rate of backwashing water is can be improved in when backwash, improves the effect of backwash.
