Description
Technical field
The present invention relates to a kind of water fetching device, particularly a kind of filtration water fetching device that is fixed on bottom, water source water intaking end.This filtration water fetching device that is arranged on water intaking end can be applied to the water treatment field such as the pretreatment of polluted source Drinking Water and water for industrial use.
Background technology
Current, the water intaking end of Drinking Water and water for industrial use is provided with grid, in order to tackle floating thing thick in water, is provided with dull and stereotyped graticule mesh, in order to tackle floating thing more tiny in water between water inlet.This water-supply method is merely able to stop suction floating thing, can not play due preliminary filtering function to the water treatment technology of water factory.
Summary of the invention
The object of this invention is to provide a kind of filtration water fetching device that is arranged on water intaking end, it is the filtration water fetching device in polluted source and the water intaking end setting of water for industrial use water factory processed, not only can stop suction floating thing, can also effectively remove the impurity particle in former water, improve effluent quality.
This is arranged on the filtration water fetching device of water intaking end, comprise tank body, water inlet, filter chamber, delivery port, outlet pipe and backwash water pipe, its feature is: this device is arranged on water factory processed water intaking end and is fixed on bottom, water source, the water inlet of grid is equipped with in one side setting of described tank body, filter chamber is set in tank body, filtrate is set in filter chamber, the opposite side of filter chamber sets out the mouth of a river, described backwash water pipe is arranged on filter chamber top, bottom, filter chamber arranges blowdown grid, described delivery port is connected with water purifying chamber, the outlet pipe that water purifying chamber's opposite side arranges connects with pump house pulsating pump.
Described filtrate is the material that proportion is lighter than water, and the material that this proportion is lighter than water is granules of polystyrene.Described polystyrene filter material layer thickness is 0.5～1.0m, and granules of polystyrene bulk density is 50～250kg/m
3, adopting homogeneous filtering material particle diameter is 2.0～5.0mm.Filtrate backwashing water intensity is 12～15 liters/m
2s, backwashing time is 4～8min.
Owing to above-mentioned water intaking filter being installed at water treatment plant's water intaking end, can effectively remove the impurity such as organic pollution, inorganic pollution and algae in water.Filter and finish, backwashing water cleans filtrate through force (forcing) pump pressurization.This water intaking end filters water fetching device and possesses that simple and reliable for structure, small investment, occupation of land are little, convenient operation and management, operation cost is low, backwashing water consumption is few, the processing water yield is large, and good purification can reduce the wearing and tearing of water pump, extend the life-span of water pump, save water factory's floor space and investment.Process is arranged on the primary filter of the filtration water fetching device of intake, can reduce the dosage of chlorine in water factory processed coagulant, flocculant and prechlorination technique, reduces aluminium salt and DBPs content in the rear water of filter.
Brief description of the drawings
Accompanying drawing is the filtration water fetching device schematic diagram that bank is arranged on water intaking end.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the filtration water fetching device that is arranged on water intaking end is described further.This filtration water fetching device, is applicable to being fixed on the former water body banks such as rivers and creeks, Hu Tang and reservoir under water, comprises tank body 1, water inlet 2, filter chamber 3, filter screen frame 9, delivery port 4, outlet pipe 6 and backwash tube 7.This device is arranged on water factory processed water intaking end and is fixed on bottom, water source and connects with pump house pulsating pump.The water inlet 2 of grid is equipped with in one side setting of filter chamber 2, at filter chamber's 3 Inner filter net frames 9, and the interior filtrate that arranges of filter screen frame 9, filtrate is the material granules of polystyrene that proportion is lighter than water.Filtrate thickness of filter bed is 0.5～1.0m, and granules of polystyrene bulk density is 50～250kg/m
3, adopting homogeneous filtering material particle diameter is 2.0～5.0mm.The particle size range of polystyrene thickness of filter bed and filtrate is determined according to the water quality condition of Practical Project Central Plains water.The opposite side of filter chamber 3 is provided with delivery port 4, and delivery port 4 is connected with water purifying chamber 5, and water purifying chamber's 5 opposite sides have outlet pipe 6.Outlet pipe 6 connects with pump house pulsating pump.This device is also provided with backwash water system, and backwashing system is, at 3 tops, filter chamber, backwash water pipe 7 is set, and bottom is provided with blowdown grid 8.Backwashing water intensity is 12～15 liters/m
2s, backwashing time is 4～8min.The present invention is filtered to water fetching device and be fixed on bottom, water source, outlet pipe 6 is connected with pump house water pump.When after starting mode of pump, the interior generation negative pressure in water purifying chamber 5 and filter chamber 3, former water enters filter chamber 3 from the water inlet 2 that installs a side, filters through polystyrene filtrate filtering layer in lateral flow mode, enters water purifying chamber 5 from delivery port 4.Former water enters pump house through primary filter through outlet pipe 6.Filter and finish, need to carry out backwash to filtrate.Switch off the pump, open backwashing pump, backwashing water pressurizes through force (forcing) pump, is rushed at the filtering layer that is positioned at device core by backwash water pipe 9 downwards.In the time that water velocity is greater than filtrate fluidizing velocity, the filter material layer at middle part reaches fluidized state completely, filtrate is extruded to device bottom, filtrate is around poured into middle part, so repeatedly, under friction between the shearing of current and filtering material particle and collision, the dirt being retained in filtering layer splits away off from filter material surface, filtrate is cleaned fully, and backwash finishes.Backwashing water from the blowdown grid 8 of filter chamber bottom discharged to water body.Backwashing water intensity is 12～15 liters/m
2s, backwashing time is 4～8min.According to test: the long 2.0m of filter chamber's appearance and size, wide 1.0m, high 2.0m, polystyrene filtrate thickness is 0.8m, granules of polystyrene bulk density is 117kg/m
3, particle diameter is 3.0mm.When water intaking flow velocity is 60m/h, when raw water turbidity is 100～120NTU, delivery turbidity is after filtering 70～85NTU, and turbidity average removal rate is 25%～30%.In the time that the filter loss of flood peak reaches 2m, filtration time is 7.3h.Filtrate backwashing water intensity is 12 liters/m
2s, backwashing time is 5min.The backwash water yield is few.Test has obtained the good result of expection.
Intake of the present invention has adopted filter, compared with existing intake, can effectively remove the impurity particle in former water, reduces the turbidity of former water.Can reduce waterworks sedimentation basin area 10%～15%, filter tank area 5%～10%, saves water factory's floor space and investment.
