Background technology
Current, the water factory water intaking end of Drinking Water and water for industrial use is provided with grid, in order to tackle floating thing thick in the water, is provided with dull and stereotyped graticule mesh between water inlet, in order to tackle floating thing more tiny in the water.This water-supply method is merely able to stop to suck floating thing, can not play due preliminary filtering function to the water treatment technology of water factory.
The utility model content
The purpose of this utility model provides a kind of fixed filtration water fetching device, it is the fixed filtration water fetching device in the water intaking end setting of polluted source and industrial water works, not only can stop the suction floating thing, can also remove the impurity particle in the former water effectively, improve effluent quality.
This fixed filtration water fetching device, comprise tank body, water inlet, filter screen frame, the filter chamber, delivery port, outlet pipe and backwash water pipe, its characteristics are: this device is installed in water factory water intaking end and is fixed on the bottom, water source, the water inlet of grid is equipped with in one side setting of described tank body, the filter chamber is set in the tank body, filter screen frame is set in the filter chamber, filtrate is set in the filter screen frame, the opposite side of filter chamber sets out the mouth of a river, described backwash water pipe is arranged on filter chamber top, the bottom, filter chamber arranges the blowdown grid, and described delivery port is connected with water purifying chamber, and the outlet pipe that water purifying chamber's opposite side arranges connects with the pump house pulsating pump.
Described filtrate is the proportion material 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 the granules of polystyrene bulk density is 50～250kg/m
3, adopting the homogeneous particle diameter is 2.0～5.0mm.Filtrate backwashing water intensity is 12～15 liters/m
2S, backwashing time are 4～8min.
Because the water intaking end is provided with the filtration water fetching device at the water source, can remove the impurity such as organic pollution, inorganic pollution and algae in the water effectively.Filter and finish, backwashing water cleans filtrate through the force (forcing) pump pressurization.That this fixed filtration water fetching device possesses is simple and reliable for structure, small investment, occupation of land are little, convenient operation and management, operation cost is low, the backwashing water consumption is few, the processing water yield is big, and good purification can reduce the wearing and tearing of water pump, prolong the life-span of water pump, save water factory's floor space and investment.Pass through the primary filter of the fixed filtration water fetching device of intake, can reduce the dosage of water factory processed medicament and chlorine, reduce aluminium salt and DBPs content in the water of filter back.
Description of drawings
Accompanying drawing is fixed filtration water fetching device schematic diagram.
The specific embodiment
Be described further below in conjunction with the enforcement of accompanying drawing to fixed filtration water fetching device.This fixed filtration water fetching device is fit to be fixed on rivers and creeks, former water body bank, the pool, lake under water, comprises tank body 1, water inlet 2, filter chamber 3, delivery port 4, outlet pipe 6 and backwash tube 7.This device is installed in water factory water intaking end and is fixed on the bottom, water source and connects with the pump house pulsating pump.The water inlet 2 of grid is equipped with in one side setting of filter chamber 3, and filter screen frame 9 is set in filter chamber 3, in the filter screen frame 9 filtrate is set, and filtrate is the proportion granules of polystyrene lighter than water.The filtrate thickness of filter bed is 0.5～1.0m, and the granules of polystyrene bulk density is 50～250kg/m
3, adopting the homogeneous filtering material particle diameter is 2.0～5.0mm.The particle diameter of polystyrene thickness of filter bed and filtrate is determined according to the water quality condition of actual engineering 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 the pump house pulsating pump.This device also is provided with the backwashing water system, and backwashing system is that 3 tops arrange backwash water pipe 7 in the filter chamber, and the bottom is provided with blowdown grid 8.Backwashing water intensity is 12～15 liters/m
2S, backwashing time are 4～8min.The utility model is filtered water fetching device be fixed in the bottom, water source, outlet pipe 6 is linked to each other with the pump house water pump.Behind starting mode of pump, produce negative pressure in water purifying chamber 5 and the 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 the lateral flow mode, enters water purifying chamber 5 from delivery port 4.Former water enters the water pump aqueous humor through primary filter through outlet pipe 6.Filter and finish, need 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 of filter chamber downwards by backwash water pipe 9.When water velocity during greater than the filtrate fluidizing velocity, the filter material layer at middle part reaches fluidized state fully, filtrate is extruded to the device bottom, filtrate is on every side poured into the middle part, so repeatedly, under friction between the shearing of current and filtering material particle and collision, the dirt that is retained in the filtering layer splits away off from filter material surface, filtrate is cleaned fully, and backwash finishes.Backwashing water from the grid 8 of filter chamber bottom discharged to water body.Backwashing water intensity is 12～15 liters/m
2S, backwashing time are 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, the granules of polystyrene bulk density is 117kg/m
3, particle diameter is 3.0mm, particle diameter of filter medium grating K80 is 1.05～1.1.When the water intaking flow velocity be 60m/h, when raw water turbidity was 100～120NTU, delivery turbidity after filtering was 70～85NTU, the turbidity average removal rate is 25%～30%.When the loss of flood peak of filtration device reached 2m, filtration time can reach 7.3h.Filtrate backwashing water intensity is 12 liters/m
2S, backwashing time are 5min.The backwash water yield is few.Test has obtained the good result of expection.
The utility model intake has adopted filter, compares with existing intake, can remove the impurity particle in the former water effectively, reduces the turbidity of former water.Can reduce waterworks sedimentation basin area 10%～15%, filter tank area 5%～10% is saved water factory's floor space and investment.
