Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a flocculation filtration device for high-turbidity water. Background Technology
[0002] High-turbidity water bodies refer to water bodies containing a large number of suspended solid particles (such as clay, silt, algae, microorganisms, organic matter, etc.), characterized by low transparency and a turbid appearance. Turbidity, as a key physical indicator for measuring the clarity of water, mainly reflects the ability of particulate matter in the water to scatter and absorb light. Such water bodies not only affect sensory perception but also pose multiple hazards: the particulate matter itself may carry pathogenic microorganisms, heavy metals, and organic pollutants, threatening drinking water safety; turbidity interferes with disinfection processes (such as chlorine disinfection), reducing disinfection efficiency; suspended solids easily deposit in pipes and equipment, increasing treatment difficulty and cost; high turbidity also hinders the photosynthesis of aquatic plants, disrupting the balance of the aquatic ecosystem.
[0003] Flocculation technology is the most core and efficient physicochemical treatment method for dealing with high turbidity water. It aims to use chemical agents (flocculators) to destabilize and aggregate fine and stable colloidal and suspended particles in the water to form large flocs that are easy to settle or filter out.
[0004] High-turbidity water undergoes flocculation, producing a mixture of flocs and water. The flocs need to be separated. Existing separation methods mainly include static sedimentation, pressure filtration, or membrane filtration. Static sedimentation has too low efficiency in separating flocs, while pressure filtration and membrane filtration require external energy to create a pressure difference. Moreover, during pressure filtration, flocs clog the filter screen or membrane, requiring frequent replacement of the filter screen or membrane, resulting in high maintenance costs. Therefore, a low-cost separation device is needed to separate flocs from water. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a flocculation filtration device for high turbidity water.
[0006] The technical solution of this utility model is: a high-turbidity water flocculation filtration device, including a water inlet tank, a vortex pool connected to the right side of the water inlet tank, a vertical pipe connected to the bottom of the vortex pool, a collection tank connected to the right side of the vertical pipe via a horizontal pipe, a plurality of sedimentation devices connected to the right side of the collection tank, a drainage trough connected to the right end of the plurality of sedimentation devices, a dosing device provided above the vortex pool, and a turbine provided at the connection between the vortex pool and the vertical pipe.
[0007] Furthermore, the dosing device includes a dosing chamber, which is connected to the vortex pool by multiple support rods. The top of the dosing chamber is provided with a dosing port, and a spiral feed rod is rotatably connected inside the dosing chamber. The lower end of the spiral feed rod is connected to the center drive of the turbine.
[0008] Explanation: The water flow drives the turbine to rotate, which in turn drives the screw feeder to rotate, causing the flocculant in the dosing chamber to fall into the vortex pool, thus achieving automated flocculant addition without consuming electricity.
[0009] Furthermore, the sedimentation device includes a horizontal water tank connected to the collection pool, with multiple sedimentation pipes located below the horizontal water tank and a drain valve located below the sedimentation pipes.
[0010] Explanation: The flocculant reacts with suspended solids in the wastewater to form flocs. The flocs flow in the horizontal water tank. The heavier flocs enter the settling pipe under the action of the water flow. After the settling pipe is full of flocs, the connection between the horizontal water tank and the collection tank is blocked by a blockage agent, so that the water flow no longer flows into the horizontal water tank. The flocs are discharged through the drain valve.
[0011] Furthermore, a horizontally positioned central shaft is provided inside the transverse pipe. The left end of the central shaft is connected to the inner wall of the transverse pipe, and the right end of the central shaft is fixed to the inner wall of the transverse pipe via a connecting rod. Multiple turbines are rotatably connected to the central shaft.
[0012] Explanation: The water flow drives the second turbine to rotate on the central shaft. The rotating second turbine acts as a stirrer, improving the mixing efficiency of the flocculant and the wastewater.
[0013] Furthermore, the bottom of the settling device is equipped with a sludge collection tank.
[0014] Note: After the flocculent material is discharged through the settling pipe, it falls into the sludge collection tank and is then collected.
[0015] The beneficial effects of this utility model are:
[0016] This invention utilizes water flow to drive a turbine, which in turn rotates a screw feed rod, causing the flocculant in the dosing chamber to fall into a vortex pool, thus achieving automated flocculant addition. The resulting flocs are separated through a settling pipe. Compared to static sedimentation, this flocculation filtration equipment is more efficient, with a continuous water flow. Compared to pressure filtration, it consumes less energy and does not require frequent filter replacements. Compared to membrane filtration, it is more cost-effective and avoids the need to replace the filter membrane. The entire system requires no external energy supply, is environmentally friendly and low-cost, has low maintenance costs, and offers high efficiency in separating flocs. Attached Figure Description

Detailed Implementation
[0020] Example 1:
[0021] like Figure 1 , Figure 2 As shown, a high-turbidity water flocculation filtration device includes a water inlet trough 1, a vortex pool 2 connected to the right side of the water inlet trough 1, a vertical pipe 3 connected to the bottom of the vortex pool 2, a collection pool 5 connected to the right side of the vertical pipe 3 via a horizontal pipe 4, a plurality of sedimentation devices 6 connected to the right side of the collection pool 5, a drainage trough 7 connected to the right end of the plurality of sedimentation devices 6, a dosing device 8 provided above the vortex pool 2, and a turbine 21 provided at the connection between the vortex pool 2 and the vertical pipe 3.
[0022] The dosing device 8 includes a dosing chamber 81, which is connected to the vortex pool 2 by multiple support rods 82. The top of the dosing chamber 81 is provided with a dosing port 83. A spiral feed rod 84 is rotatably connected inside the dosing chamber 81, and the lower end of the spiral feed rod 84 is connected to the center drive of the turbine 21.
[0023] The water flow drives the turbine 21 to rotate, which in turn drives the screw feed rod 84 to rotate, thereby causing the flocculant in the dosing chamber 81 to fall into the vortex pool 2, thus achieving automated flocculant addition without consuming electricity.
[0024] The settling device 6 includes a horizontal water tank 61 connected to the collection tank 5, and a plurality of settling pipes 62 are provided below the horizontal water tank 61, and a drain valve 63 is provided below the settling pipes 62.
[0025] Flocculants are formed by the interaction of flocculants with suspended solids in wastewater. The flocculants flow in the horizontal water tank 61. The heavier flocculants enter the settling pipe 62 under the action of the water flow. After the settling pipe 62 is full of flocculants, the connection between the horizontal water tank 61 and the collection tank 5 is blocked by a blockage agent, so that the water flow no longer flows into the horizontal water tank 61. The flocculants are discharged through the drain valve 63.
[0026] Example 2:
[0027] The difference between this embodiment and embodiment 1 is that in this embodiment, a horizontal central shaft 41 is provided inside the transverse pipe 4. The left end of the central shaft 41 is connected to the inner wall of the transverse pipe 4, and the right end of the central shaft 41 is fixed to the inner wall of the transverse pipe 4 through a connecting rod 42. Multiple turbines 43 are rotatably connected to the central shaft 41.
[0028] Compared to Example 1, in this embodiment, the water flow drives the turbine 43 to rotate on the central shaft 41. The rotating turbine 43 plays a stirring role, improving the mixing efficiency of flocculant and sewage.
[0029] Example 3:
[0030] The difference between this embodiment and embodiment 2 is that the bottom of the sedimentation device 6 in this embodiment is provided with a sludge collection tank 9.
[0031] Compared to Example 2, in this embodiment, the flocculants are discharged through the settling pipe 62 and fall into the sludge collection tank 9, where they are then collected.
[0032] The working method of the above embodiments includes the following steps:
[0033] S1. Sewage is introduced into the water inlet trough 1. The sewage flows into the vortex pool 2 along the water inlet trough 1. The water flow drives the turbine 21 to rotate. The rotation of the turbine 21 drives the screw feed rod 84 to rotate, which in turn causes the flocculant in the dosing bin 81 to fall into the vortex pool 2. The flocculant mixes with the sewage to form flocs.
[0034] S2. Under the action of water flow, turbine 43 is driven to rotate and stir the sewage. After the flocculant and sewage are mixed evenly, they are discharged into the collection tank 5. Then, the sewage is diverted through multiple horizontal water tanks 61. After the sewage flows through the settling pipe 62, it accumulates in the settling pipe under the action of gravity. When the settling pipe 62 is full of flocculants, the connection between the horizontal water tank 61 and the collection tank 5 is blocked by a blockage, so that the water flow no longer flows into the horizontal water tank 61. The flocculants are discharged through the drain valve 63 and fall into the sludge collection tank 9 for centralized collection.
[0035] The drain valve 63 in the above embodiments are all commercially available products. As long as it can achieve the function of this utility model, it is acceptable. Those skilled in the art can choose to use it based on common sense, and no special limitations are made here.
