[0036] In some embodiments, the first direction is perpendicular to the second direction; a water inlet hole 108 is provided on the water inlet wall of the water inlet area 101, the length direction of the water inlet wall is parallel to the first direction, and the length direction of the sedimentation area 201 of the horizontal flow sedimentation tank is parallel to the first direction, so that the water inlet area 101 is inletted through the water distribution weir 103, so as to facilitate flow distribution in the water distribution area.

[0037] The water distribution device provided in at least one embodiment realizes flow distribution by setting a plurality of adjusting sub-areas with adjustable lengths, thereby facilitating flow regulation and realizing accurate flow distribution to a certain extent, flexibly distributing different flows, and being more adaptable to different operating conditions, and arranging a drainage channel 111 with a gradually varying width, so that the flow entering the sedimentation area 201 of the horizontal flow sedimentation tank can be evenly distributed to a greater extent, thereby ensuring the overall operating effect of the horizontal flow sedimentation tank.

[0038] In some embodiments, the water distribution area has two gates 104, which are arranged at intervals to divide the water distribution area into three adjustment sub-areas, and the positions of the two gates 104 in the first direction are configured to be adjustable. The water distribution area is divided into three adjustment sub-areas by the two gates 104, and the flow size distribution of different adjustment sub-areas is achieved by adjusting the positions of the two gates 104.

[0039] It should be noted that the number of gates 104 in the water distribution area is not limited to 2, and there may be 3 to 10 gates 104, etc. The water distribution area can be divided into different regulating sub-areas by multiple gates 104.

[0040] In some embodiments, the water distribution area is provided in the form of a water distribution channel 102 , and a water distribution weir 103 is provided at the upper edge of the water distribution channel 102 .

In one embodiment, the number of slot assemblies is 6, and the two gate plates 104 are inserted into different slot assemblies to achieve the regulation of different regulating sub-areas.

Through such a setting, the gate plate 104 needs to be manually aligned when placed in the slot assembly so that it can smoothly fall into the slot of the slot assembly.

[0043] In some embodiments, the three regulating sub-areas are respectively the first regulating sub-area 106, the second regulating sub-area 107 and the third regulating sub-area 118, the drainage channel 111 is connected to the first regulating sub-area 106; the second regulating sub-area 107 is connected to the first water outlet pipe 115, and the third regulating sub-area 118 is connected to the second water outlet pipe 116.

[0044] In one embodiment, the first regulating sub-area 106 is provided with a water inlet hole 108, and the drainage channel 111 is connected to the first regulating sub-area 106 through the water inlet hole 108. After water distribution, the sewage enters the drainage channel 111 through the water inlet hole, and the channel width of the drainage channel 111 is continuously reduced from the water inlet hole 108 to the far end. The channel width design of the gradual channel and the setting of the water inlet hole 108 make the water inlet flow rate evenly arranged in the width direction (second direction) of the sedimentation area 201.

[0045] In one embodiment, the flow velocity of the water flow at the proximal end of the drainage channel 111 is 0.46 m / s, and the flow velocity at the distal end is 0.93 m / s. The sewage flows out through the water inlet hole 108 of the drainage channel 111, and the flow velocity of the water flow in the water inlet hole 108 is 0.4 m / s.

[0047] In some embodiments, a baffle 110 is provided at the first end of the water distribution channel 102. When a water blocking gate is inserted into a slot 109 formed by a channel steel provided at the baffle, the incoming water can be prevented from entering the sedimentation area 201 of the horizontal flow sedimentation tank, thereby saving investment and increasing flexible operation.

The plurality of water outlets 112 are disposed at intervals along the length of the drainage channel 111. The water can flow to the sedimentation area 201 of the advection sedimentation tank through the water outlets 112.

[0049] In some embodiments, the water distribution device further includes a rectifying plate 113, the upper end of which is connected to the drainage channel 111, and the lower end of which is a free end, for making the water flowing out through the water outlet 112 flow downward and flow out through the lower end of the rectifying plate 113. The rectifying plate 113 is used to rectify the water flowing out of the drainage channel 111, so that the incoming water enters the sedimentation area 201 of the horizontal flow sedimentation tank at the lower middle of the pool depth, thereby ensuring the operation effect of the horizontal flow sedimentation tank.

Through the cooperation of the rectifying plate 113 and the water distribution wall 114, the water flowing out of the diversion channel 111 is rectified by the rectifying plate 113 and enters the sedimentation area 201 of the horizontal flow sedimentation tank from the middle and lower part of the water distribution wall 114, thereby ensuring the overall operation effect of the horizontal flow sedimentation tank.
