The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0022] like Figures 1 to 3As shown, a high-efficiency flocculation sedimentation device of the present application includes: a water treatment structure and a filter tank, wherein the water treatment structure includes: a flocculation sedimentation tank 10 arranged at the upper layer and a clean water tank 20 arranged at the lower layer. In this way, by designing the flocculation sedimentation tank 10 and the clean water tank 20 as a structure structure of upper and lower layers, the floor space is effectively saved, the pipeline structure is simplified, and the treatment operation of the sediment can be optimized, the installation cost is reduced, and the cleaning efficiency of the overall device is improved. Specifically:

[0023] The flocculation sedimentation tank 10 includes: a raw water inlet pipe 101, an inlet area 102 for inputting raw water, a flocculation area 104 for adding flocculants to flocculate the raw water, a sedimentation area 109 for sedimenting the flocculated raw water, a water collection area 110 for collecting the precipitated raw water, and a water collection main pipe 114. During installation, the raw water inlet pipe 101 is connected to the inlet area 102, the inlet area 102 is connected to the flocculation area 104, and a grid 115 is provided between the inlet area 102 and the flocculation area 104 for filtering. The flocculation area 104 is connected to the sedimentation area 109 through the outlet perforated flower wall 116, and the sedimentation area 109 is connected to the water collection area 110. The water collection area 110 is provided with a plurality of perforated finger-shaped water collection grooves 111 and a water collection pool 113 connected to the plurality of perforated finger-shaped water collection grooves 111. The water in the water collection area 110 is drained into the water collection pool 113 through the perforated finger-shaped water collection grooves 111. The two ends of the water collection main pipe 114 are respectively connected to the water collection pool 113 and the water inlet end of the filter pool, so that the water in the water collection pool 113 is transported to the filter pool for filtration. The water outlet end of the filter pool is connected to the clean water pool 20, and the filtered water is then transported to the clean water pool 20 through the clean water inlet pipe 212 for final static treatment. A water baffle 103 is provided in the water inlet area 102 to buffer the kinetic energy of the raw water entering, thereby facilitating the initial sludge precipitation of the raw water.

[0024] The clean water tank 20 includes: a buffer zone 201, a retention zone 203 and a water outlet zone 205. The buffer zone 201 is used to buffer the clean water, the retention zone 203 is used for the incoming water to stay and stand, and the water outlet zone 205 is used to output the internal clean water to the municipal water room. Specifically: the buffer zone 201 is provided with a plurality of buffer walls 202, which are staggered and arranged perpendicular to the water inlet direction, so as to effectively buffer the incoming clean water; the retention zone 203 is provided with a plurality of drainage walls 204, which are staggered and arranged parallel to the water inlet direction, so as to slowly drain and stand the incoming clean water. A sump 206 is provided at the bottom of the water outlet zone 205, and the sump 206 is connected to the external water pump room through a clean water outlet pipe 207 to supply municipal water.

[0025] like Figure 1As shown in , in the flocculation zone 104, a counter-flow folding plate group 105, a unidirectional flow folding plate group 106 and a vertical flow folding plate group 107 are sequentially arranged along the water inlet direction of the water flow. The counter-flow folding plate group 105 can guide the water flow to flow in different directions in the horizontal direction to improve the flocculation efficiency. The unidirectional flow folding plate group 106 can guide the water flow to flow in a stable flow direction in the horizontal direction to stabilize the water flow. The vertical flow folding plate group 107 can guide the water flow to flow up and down in the vertical direction to improve the flocculation and filtration stroke. A brush 108 is arranged on one side of the vertical flow folding plate of the vertical flow folding plate group 107 for flocculating and filtering the raw water. The above scheme can effectively improve the flocculation and sedimentation effect and improve the treatment efficiency of the raw water.

[0026] Specifically, the raw water enters the flocculation sedimentation tank 10 from the raw water inlet pipe 101, and enters the flocculation zone 104, the sedimentation zone 109 and the water collection zone 110 in sequence. When entering the flocculation zone 104, the raw water first enters the counterflow folding plate group 105, and the raw water flow passing through the counterflow folding plate group 105 fully forms a turbulent flow state, so that the turbulent flow state of the water is fully in contact with the added PAM coagulant to form small alum flowers, and the small alum flowers collide with each other and condense in the process of passing through different folding plates to form large alum flowers. After the raw water carrying the large alum flowers flows through the co-flow folding plate group 106 and the vertical flow folding plate group 107, the flow rate gradually stabilizes, and then enters the sedimentation zone 109. As the raw water flows in the sedimentation area 109, the sludge and suspended solids gradually settle to the bottom of the sedimentation area 109. The raw water after sedimentation and separation enters the water collection area 110. The water in the water collection area 110 enters the water collection tank 113 through the perforated finger-shaped water collection tank 111. The water in the water collection tank 113 enters the filter tank (not shown in the figure) through the water collection main pipe 114. The water treated in the filter tank enters the clean water tank 20, and then passes through the buffer zone 201, the retention zone 203 and the water outlet zone 205 in sequence. Finally, the clean water is transported to the water delivery pump room through the clean water outlet pipe 207.

[0027] As a specific implementation, the perforated finger-shaped water collection trough 111 is supported and installed above the water collection area 110 by supporting pillars 112, so as to transport the clean water above the clean water tank 20 and ensure the quality of the transported water.

[0028] As a specific implementation, a sludge discharge pipe 117 is arranged at the bottom of the water inlet area 102 and the flocculation area 104 to discharge the sludge settled at the bottom, and a sludge main channel 118 is arranged on both sides of the flocculation sedimentation tank 10 to discharge the sludge, and the two ends of the sludge discharge pipe 117 are respectively connected to the sludge main channels 118 on both sides, so that the sludge in the water inlet area 102 and the flocculation area 104 is discharged into the sludge main channels 118 on both sides. A sludge collection pit 119 is arranged at the end of the sludge collection pit 119, and a sludge discharge pipe 120 is arranged at the water outlet of the sludge collection pit 119 to clean and discharge the sludge in the sludge collection pit 119.

[0029] As a specific implementation, a raw water drain pipe 121 is provided at the bottom of the sedimentation area 109 to drain the raw water in the sedimentation tank, and the outlet of the raw water drain pipe 121 is connected to the sludge main channel 118, so that when the raw water is drained, the sludge brought out is also collected in the sludge main channel 118 for cleaning. A truss-type siphon mud machine 122 is set above the sedimentation area 109. After the raw water in the sedimentation area 109 is controlled, the sludge at the bottom of the sedimentation area 109 is cleaned by the truss-type siphon mud machine 122.

[0030] The above-mentioned solution designs the flocculation sedimentation tank 10 and the clean water tank 20 as a structure of upper and lower layers, which simplifies the sludge cleaning pipeline, thereby realizing centralized and efficient cleaning of the sludge.

[0031] As a specific implementation, the sump 206 is connected to the external wet well 30 through the clean water drain pipe 208, so that it is convenient to empty the clean water tank 20 when cleaning the clean water tank 20. Mud discharge channels 210 are provided on both sides of the clean water tank 20, and a clean water tank mud discharge pipe 211 is provided at the bottom of the clean water tank 20. The clean water tank mud discharge pipe 211 is connected to the mud discharge channel 210 to discharge the sludge at the bottom of the clean water tank 20 into the mud discharge channel 210, thereby cleaning the sludge in the clean water tank 20.

[0032] As a specific implementation, the water outlet area 205 is further provided with a clean water overflow pipe 209 at a preset position on its upper side. The clean water overflow pipe 209 can be used to adjust the water level in the clean water tank 20. When the water level in the water outlet area 205 exceeds the overflow water level, the clean water overflows from the clean water overflow pipe 209 and enters the wet well 30.

[0033] As a specific implementation, the high-efficiency flocculation sedimentation device is provided with two clear water tanks 20, and the two clear water tanks 20 are symmetrically distributed, thereby improving the water treatment efficiency.

[0034] A maintenance well 40 is provided at one side of the clear water tank 20, and a maintenance entrance is provided in the maintenance well 40, so as to facilitate daily maintenance of the high-efficiency flocculation sedimentation device.

[0035] A cover plate 50 is provided above the flocculation zone 104 of the flocculation sedimentation tank 10 .
