Detailed Description
As shown in fig. 1-3, the suspension medium layer filtering system based on the hydraulic fluid state layering comprises a filtering device 1, a reflux pump 12, a water inlet dosing system 14 and a main body bracket 15; the filtering device 1 is arranged on a main body bracket 15, and the main body bracket 15 is arranged on the ground; the water inlet dosing system 14, the reflux pump 12 and the filtering device 1 form a circulation loop.
The filtering device 1 comprises a water outlet weir 2, a water outlet 3, an overflow port 4, a return port 5, an emptying port 6 and a water inlet 7; an effluent weir 2 is arranged in the filtering device 1, the effluent weir 2 is connected with a water outlet 3, and an overflow port 4 is arranged on one side of the filtering device 1; the water inlets 7 are positioned at two sides of the bottom of the filtering device 1;
the bottom of the filtering device 1 is provided with a return port 5 and an emptying port 6; the reflux port 5 is connected with a water inlet dosing system 14 through a reflux pump 12; the drain 6 is connected to a drain system via a drain pipe.
The height of the overflow 4 is higher than that of the water outlet weir 2.
The water outlet weir 2 is arranged at the inner side of the top end of the upper part of the filtering device 1, is connected with the inner wall of the upper half part of the filtering device 1, and forms a box-shaped space with an upper opening with the inner wall of the filtering device 1; the water outlet weir 2 is a saw-tooth weir or a horizontal weir.
The water outlet weir 2 is annular, water outlets 3 are symmetrically arranged on the inner bottom surface, and the water outlets 3 extend to the outer wall of the filtering device 1 through pipelines to discharge water.
The water outlet weir 2 is L-shaped in cross section, one side of the L-shape is fixed on the inner wall of the upper part of the filtering device 1, and forms a U-shaped groove with the filtering device 1.
The water inlets 7 are positioned at two sides of the bottom end of the filtering device 1; the water inlet direction is tangential to the filter device 1, the water inlets 7 on two sides are symmetrically arranged, and are connected with the water inlet dosing system 14 through pipelines.
The inner diameter of the upper half part of the filtering device 1 is gradually enlarged from bottom to top, and the lower half part is in an inverted conical funnel shape.
The water inlet dosing system 14 comprises a dosing barrel 8, a water inlet pump 9, a pipeline mixer 10, a mixing motor 11 and a water inlet pipe 13; the water inlet pipe 13 is connected with the water inlet pump 9, the water inlet pump 9 is connected with the pipeline mixer 10, and the pipeline mixer 10 is connected with the filtering device 1;
the dosing barrel 8 is respectively connected with the pipeline mixer 10 and the reflux pump 15; the top of the dosing barrel 8 is provided with a mixing motor 11, the mixing motor 11 is connected with a stirring device, and the stirring device is arranged inside the dosing barrel 8.
The water-in dosing system 14 includes a pipe mixer 10; both water inlets 7 are connected to a pipe mixer 10.
When the invention works, the water inlet pump 9 draws sewage to be treated from the water inlet pipe 13 to enter the pipeline mixer 10, the sewage in the pipeline mixer 10 is mixed with the evenly mixed medicament, and the mixture enters the filter device 1 through the water inlet 10. The water inlet and the medicament are fully mixed, which is a precondition for forming a suspension medium layer. Because the number of the water inlets 7 is 2, the water inlets are respectively positioned at two sides of the filtering device 1, the water flow entering the water inlets 7 can tangentially form vortex, which is favorable for flocculation reaction after the water inlet and the medicament are mixed, and a suspension medium layer with upper and lower layers is formed.
Then, the water inlet dosing system 14 supplies materials to the filtering device 1, the inner diameter of the inverted circular truncated cone body at the upper half part of the main body of the filtering device 1 is gradually enlarged from bottom to top, the rising flow velocity of water to be treated can be gradually reduced, and the height and the density of the formed suspension medium layer are controlled; the lower half part is in an inverted cone funnel shape, and the settled residual suspended medium layer impurities can be collected and then returned to the dosing system 14 through the return port 5 or uniformly discharged out of the system through the emptying port 6.
The medicament in the water inlet medicament adding system 17 is mainly flocculant or medicament with the same function, and forms a suspension medium layer through mixing and flocculation of the medicament and water inlet, and the suspension medium layer with a filtering function can be formed through the combined action of the medicament and the water inlet medicament and the hydraulic fluid state formed by the structure of the filtering device 1, so that the water inlet is effectively filtered and phosphate is removed. At this time, the liquid passing through the filter layer enters the water outlet weir 2 and is discharged through the water outlet 3; when the liquid height is higher than the water outlet weir 2, overflow is carried out through an overflow port 4; the water discharged from the water outlet 3 enters a subsequent disinfection system or a discharged water body, and the overflow water discharged from the overflow port 4 flows back to the front end of the system.
The impurities in the residual suspended medium layer which is settled at the bottom of the filtering device 1 are refluxed to the dosing barrel 8 through the action of the reflux pump 12, so that the drug consumption of the device is reduced while the suspended medium quantity in the filtering device 1 is ensured, and the running cost is saved. The drain 6 is connected to a drain system via a drain pipe.
