A kind of rainwater, sewage two-filtration devices
The utility model relates to rainwater, technical field of sewage, especially a kind of rainwater, effluent treatment plant and method.
Relate to the field of water treatment in rainwater treatment, sewage disposal etc., for organic removals such as suspensions in water, the utilization of filter for installation is very general.
In current water treatment filter, such as quartz sand, haydite, zeolite etc., usually adopt and fall flow filters, there is certain removal effect, generally adopt up-flow during backwash, the main problem of this type of filtration system is: (1) mainly removes suspension in water, and removal effect is limited; (2) usually need to arrange air pipe line, system complex when cleaning filtrate; (3), when cleaning filtrate, water consumption is generally larger.
Utility model content
For the defect that existing filtration system exists, the utility model provides a kind of rainwater, sewage filter system, can effectively process rainwater, sewage, remove suspension and most of dissolved organic matter in water, thus obtain the process water of better water quality, and adopt bidirectional flow to rinse, to be applicable to the feature of dual filtrate itself, Total Cost Ownership is low.
The technical solution adopted in the utility model is: adopt novel dual filter, and the water that need filter is through arranging double-deck lightweight suspension filtrate coarse filtration, then through the filter of carbon leaching material essence, the water after filtration is flowed out by the outlet pipe of filter side.When rinsing filtrate, flushing water flows into by arranging valvular flushing water water inlet pipe, and enters in the middle part of filter, and the water after cleaning flows out from top overfall, bottom water inlet respectively.
The preferred movable water inlet of above-mentioned filter, during water inlet, upper guard-plate is washed open, falls to bottom of device during draining, if two movable rods are connected with water inlet pipe, has 1cm above baffle plate
2circular hole is in being evenly arranged, and open area is consistent with water inlet pipe size.
The preferred rectification screen cloth of above-mentioned filter, in hollow umbrella, umbrella cover is towards water inlet inflow direction, and hollow space is that to be provided with the maximum seam of 7-8mm according to filtrate diameter wide.
The preferred lightweight suspension filtrate of above-mentioned filter, the filtrate light by density ratio water forms, and is arranged to bilayer, and each layer particle size range is 6-10mm and 10-20mm respectively.
The preferred isolating strainer of above-mentioned filter, aperture of filter screen 7-8mm.
The preferred carbon leaching material of above-mentioned filter is granular activated carbon, is made up of the shell filtrate of at least one material, and granularity is 8-16 order.
Above-mentioned filter is preferably isolated filter plate and is provided with through stockless filter, supports filter plate and is evenly provided with 20 object through holes.
The exit of the preferred delivery port of above-mentioned filter, overfall is provided with 20 order grids.
The beneficial effects of the utility model are:
(1) movable delivery port and rectification screen cloth, effectively can distribute current, makes follow-up filtration system play larger benefit.
(2) lightweight suspension filtrate and carbon leaching material double filtration, can reduce the concentration of pollutant in water greatly, ensures the effect of filtering water.
(3) for the feature of two kinds of different filtrates, adopt in the middle of water inlet respectively to upper, rinse downwards, while obtaining maximum developing result, taken into full account economy.
Accompanying drawing explanation
The rainwater that Fig. 1 provides for the utility model, the structural representation of sewage filter system.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, the utility model embodiment provides a kind of rainwater, sewage two-filtration devices, comprising: water inlet pipe 1 and movable delivery port 2; Movable delivery port 2 is arranged on the below of rectification screen cloth 3; The top of rectification screen cloth 3 is provided with lightweight suspension filtrate 4.Wherein bilayer is arranged to by lightweight suspension filtrate 4, isolated between double-deck light suspended filter material by filter screen 5; Filter 6 is arranged on isolation filter plate 7; Carbon leaching material 9 is supported by support filter plate 8, and filter plate can for arranging the filter plate of multiple through hole, and through hole can evenly be arranged; Communicate with flushing water water inlet pipe 12 between isolation filter plate 7 with support filter plate 8.Outlet pipe 11 is arranged on the side of filter; Overflow pipe 10 is also as the drainpipe of top carbon leaching material flushing water, and water inlet pipe 1 is also as the drainpipe of below lightweight suspension filtrate flushing water.
The rainwater that the utility model provides, the course of work of sewage filter system are:
(1) when filtering beginning, open the valve of described drainpipe 11, close the valve of described flushing water water inlet pipe 12, rainwater, sewage wash the baffle part of movable delivery port 2 open by water inlet pipe 1, through over commutation screen cloth on current direction, described rectification screen cloth can play the effect distributing current, prevent lightweight suspension filterins media run-off.
(2) current are through over commutation screen cloth, and filter with the lightweight suspension filtrate 4 that the mode upwards flowed is arranged respectively by described bilayer, screen cloth 5 can isolate lightweight suspension filtrate.
(3) current are through lightweight suspension filtrate secondary coarse filtration, enter by the filter 6 be arranged on described isolation filter plate 7, upwards flow, carry out essence by the active carbon 9 being arranged on isolation filter plate 8 to filter, in this preferred version is implemented, the water after filtration enters the drainpipe 11 being provided with grid and flows into water storage apparatus.When the water after filtering reaches overflowing water port height, the overflow pipe 10 through being provided with grid is discharged.
(4) rinse time, close the valve of described drainpipe 11, open the valve of described flushing water water inlet pipe 12, after flushing water access to plant respectively to upper, rinse downwards.
In sum, the rainwater that the utility model provides, sewage two-filtration devices, while SS obtains higher clearance, in water, particularly dissolved organic matter is also corresponding is removed for other pollutants, greatly strengthen the effect of water treatment, and adopts double-deck light suspended filter material and carbon leaching material, double filtration is filtered through coarse filtration and essence, have the cycle of operation long, developing result is remarkable, and operation maintenance is simple, the advantage of good economy performance.
The above is only preferred embodiment of the present utility model, it should be pointed out that for those skilled in the art, and under the prerequisite not departing from the utility model principle, done some modifications also should regard as protection domain of the present utility model.
