Embodiment
Below in conjunction with preferred embodiment, to according to embodiment provided by the utility model, details are as follows：Refer to attached
Figure, present embodiments provides a kind of EPS floating beds precipitation filter tank, including raw water area 2, water distribution area 9, preformed precipitate area 8, filtering area 7, clear
Pool 4, exhalant region 14 and 21 7, sludge area functional areas.The preformed precipitate area is paved with cross section and adopted for regular hexagon column jecket 8-1
Cellular assembly 22 is formed with seamless spliced, inclined tube setting angle is horizontal by 60 °~80 ° angles, the height of assembly
Spend for 400~800mm.The EPS floating beds precipitate filter tank, provided with water distribution system, initial filter water discharge system, backwash into water system
System, recoil water discharge system and mud discharging system.The water distribution system, it is made up of water distributing pore 1 and water inlet control valve 3；It is described
Backwash water inlet system is made up of water after filter water inlet pipe 13 and water after filter water inlet control valve 12；The recoil water discharge system is by anti-
Flush water discharge pipe 18 and recoil water discharging valve 17 form；The initial filter water discharge system is arranged by initial filter water discharge spout 16 and initial filter water
Valve 15 is put to form；The mud discharging system is made up of perforated sludge discharge pipe 20 and spoil disposal control valve 19.The water inlet control valve 3,
Water after filter water inlet control valve 12, recoil water discharging valve 17, initial filter water discharging valve 15 and spoil disposal control valve 19 are using electric and pneumatic
Control；Valve, caliber and hole size determine according to sewage disposal scale.
Column jecket 8-1 is made up of the inclined column jecket of a regular hexagon 6 pieces of swash plates, and n inclined column jecket composition is paved with precipitation
The cellular assembly in area.The hexagon inclined tube opposite side bore length in the preformed precipitate area is 80-120mm.
Set up the function of the cellular assembly in preformed precipitate area：
1) when sewage rises filtering, when sewage flocculation suspension passes through swash plate, each swash plate surface can be deposited to, is produced
Buildup effects, swash plate surface increase supporting layer area, make the sewage of rising retain pollutant by swash plate, so as to reach sludge settling
Effect, the current of rising are purified；2) during filtrate recoil cleaning, upper strata EPS filtrates flow down drop with back-flushing, pass through swash plate
During the honeycomb ducts of settling zone, filtrate and the swash plate surface of pollution collide, and clean mutually, add the purification effect of backwash
Fruit.Practical significance is that upward flow filter and inclined-plate clarifying basin organic assembling are integrated, and improves precipitation plus the effect of filtering, simultaneously
Overcome sloping plate deposition district sludge and clean halfway drawback, while be also effectively improved the cleaning function of filtrate backwash.
This combination by greatly promote the efficiency of sloping plate deposition and media filtration and overcome that they are individually present at present can not self-cleaning
Disadvantage；3) angle of swash plate can adjust the dynamics that they collide, cleaned again.
As shown in figure 1, during the EPS floating beds precipitation filter, water after filter water inlet control valve 12, recoil water discharging valve
17th, initial filter water discharging valve 15 and spoil disposal control valve 19 are closed, and water inlet control valve 3 is in opening, and now sewage is from raw water
Area 2, filter tank is entered by filter tank bottom water distributing pore 1, and pass sequentially through preformed precipitate area 8 and filtering area 7 from bottom to top, the filter of EPS gradings
Expect that combination filter 6 by anti-floating filter plate 5 and on filter plate retains, sewage is first by preformed precipitate area 8, the part in sewage
Suspended particulate substance precipitates herein, then again by filtering area 7, after the tiny suspended particulate substance in sewage is trapped, then passes through group
Close filter 6 and enter clear water zone 4, exhalant region 14 is discharged into after finally being collected by water leg 10.
As shown in Fig. 2 during the EPS floating beds precipitation filter back washing, there is two processes：It is back-flushing discharge first
Valve 17 and water after filter water inlet control valve 12 are opened, while water inlet control valve 3 is closed, the liquid level rapid decrease in filter tank, grading filter
The bed of material quickly moves down with liquid level, and is cleaned by carrying out mutually collision between preformed precipitate area 8 and inclined tube, and now back-flushing leads to
Recoil water discharge spout 18 is crossed to discharge；When the liquid level in filter tank is reduced to design level value, water after filter water inlet control valve 12 and anti-
Flush water discharge valve 17 is closed, while water inlet control valve 3 and initial filter water discharging valve 15 are opened, and the liquid level in filter tank is begun to ramp up, and
Graded filtering media layer also rises with the liquid level in filter tank, and when initial filter water water quality reaches design load, initial filter water discharging valve 15 is closed, instead
Rinse and terminate to recover filtration condition.
As shown in the figures 1 and 2, when the EPS floating beds precipitation filter tank mud position reaches design peak, spoil disposal control valve 19 is opened
Open, filter tank starts spoil disposal, and when mud position reaches design minimum, spoil disposal control valve 19 is closed, and spoil disposal terminates.
