7, operating cost is low.
There is multiple pattern in V-type filter tank 4, and is with a long history as the conventional rapid filter use of filtrate with quartz sand.On this basis, people have been developed the rapid filter of other pattern from different technological angles.V-type filter tank 4 adopted more slightly, the quartz sand filtering layer of thicker single-size; Adopted gas, simultaneously backwash of water that filtering layer is expanded to have the surface sweep washing for the treatment of drainage concurrently; The techniques such as air cushion distribution air and special-purpose strainer head carry out that gas, moisture are joined have been adopted.It has, and effluent quality is good, filtering velocity is high, the cycle of operation is long, backwash effect is good, energy-conservation and be convenient to the characteristics such as automatic management.There is two states in the V-type filter tank in running, i.e. filtration condition and backwash state.
(1) filter process
Until drainage by the total canal of water inlet behind water intaking valve and square hole, overflow across crest of weir and enter through side opening again and treated that drainage floods the V-type groove on edge, enter the filter tank through the uniform distributing hole of bottom land and V-type groove weir respectively.Water flows into bottom space through strainer head after the filter of being filtered by the homogeneous filtering material filtering layer, imports air water by square hole and distributes pipe duct, flows into clear water reserviors at the trapped well in piping lane, effluent weir, clear water canal.
(2) backwash process:
Close water intaking valve, but the square hole that some water inlet is still often opened from both sides flows into the filter tank, to drainage ditch one side, form surface sweep washing by V-type groove one effluent.Then the opening water discharge valve is discharged pond face water until the filter tank water surface is equal with V-type groove top from rhone.Backwash process often adopts " gas punching → air water recoils → the water punching simultaneously " three steps.Gas charges and attacks and drives air valve into, opens air feed equipment, and air distributes the top aperture of canal evenly to enter the bottom, filter tank through air water, by the strainer head ejection, filter material surface impurity is cleaned and suspends in water, and is poured rhone by surface sweep washing water.Simultaneously backwash of air water starts flush water pump in the gas punching, open rinse water valve, and backwashing water also enters air water and distributes canal, gas, water flow into bottom, filter tank water distributing area through aperture and square hole respectively, evenly enter the filter tank through strainer head, filtrate is further washed, and table is swept still and proceeded.Stop the gas punching, water punching table is swept still and is continued separately, at last impurity in the water is all poured rhone.
The air water associating backwashing manner that adopt in the V-type filter tank is considered to the most effective in all backwashing manners, and its advantage is:
1. utilize air that filtrate is produced necessary stirring, and the friction by air-flow and filtering layer and shearing action peel off the attachment on the filtrate, under the same backwash rate, the shearing of air douche approximately is 2 times of water punching shear.
2. therefore the suspension under flushing water is only peeled off for liquefaction greatly reduces backwash rate, has saved washing water quantity.Adopt more traditional single Shui Chong filter tank, filter tank of air water associating backwashing manner to compare, can clean thoroughly filtrate, the phenomenon that traditional filter tank long-play filtrate hardens, stops up can not occur, and its flushing water is good far below traditional filter tank, adopt traditional filter cell rinse water consumption of single water flushing to account for 8%～10% of water yield per day, and the V-type filter cell rinse water consumption that adopts air water to unite flushing only account for about 2.4% of water yield per day.
The V-type filter tank adopts the V-type groove can guarantee that the water inlet water distribution is even; In backwash, carry out the filter tank surface sweep washing.Can rapidly impurity be entered in the sump, thereby reduce washing time; During backwash, the filtrate microdilatancy can reduce the filter tank degree of depth; High, the convenient management of operation automaticity.
