After the technical scheme is adopted, a plurality of layers of porous baffles are horizontally arranged in the first-stage mixing reaction chamber, and the suspension layer of the solid particles of the sludge is mainly positioned in the middle lower area of the first-stage mixing reaction chamber, so that the porous baffles can effectively act on the solid particles floating upwards excessively, and the action mode of the porous baffles is mainly to reserve through holes for water flow to pass through. The area between the through holes is a closed part, the closed part is protruded upwards when viewed from the upper visual angle, and correspondingly, the closed part is in an upwards-recessed state when viewed from the lower visual angle. In this case, when the floating solid particles enter the sealing part and are blocked by the porous baffle, the floating solid particles can only move downwards in the turning direction, and due to the action of inertia, the downward moving solid particles can not easily enter the through holes on the side surface any more, so that the floating solid particles at the corresponding position of the sealing part can be effectively blocked. And when the solid particles corresponding to the through holes float upwards, the solid particles can smoothly pass through the through holes, but the positions of the through holes on the two layers of porous baffle plates which are adjacent up and down are staggered, so that the solid particles floating upwards through the through holes just correspond to the closed part of the upper layer of porous baffle plate, and can be blocked and settled down.

The result is an effective reduction in the amount of sludge solids entering the secondary mixing chamber and return channel with the water stream. The solid particles or suspended matters are reduced to enter the overflow port along with the water flow, so that the water quality of clear water collected by the overflow port is improved.
Preferably, the through hole protrudes downwards to form a cylindrical body, and a plurality of strip-shaped holes are longitudinally formed in the side wall of the cylindrical body. The strip-shaped holes are arranged, so that the area of passing water can be increased, and the influence on water flow due to the arrangement of the porous baffle is reduced.

The shape of the clarification tank is generally circular, and the shape of the porous baffle is correspondingly arranged.
further preferably, the periphery of the circular porous baffle is also provided with an annular porous baffle which is arranged from the inner side to the outer side in an inclined and downward mode. The annular porous baffle plate arranged on the periphery is used for preventing solid particles from floating upwards from the edge of the circular porous baffle plate. In addition, annular porous baffle is by interior direction finding outside slope setting downwards for the face is perpendicular with the rivers direction, is favorable to rivers to pass through.
Preferably, a guide plate is arranged at the top of the first-stage mixing reaction chamber, the guide plate is in the shape of a truncated cone, an annular water distribution channel is arranged at the lower part of the inner side of the guide plate, a plurality of water inlet holes are symmetrically formed below the water distribution channel, a water inlet pipe is connected to the guide plate, and the water inlet pipe is communicated with the water distribution channel.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the structure of the porous baffle can prevent solid particles from floating upwards, but cannot prevent the solid particles from settling and water flow from rising. The result is an effective reduction in the amount of sludge solids entering the secondary mixing chamber and return channel with the water stream.

The top of the first-stage mixing reaction chamber 13 is provided with a guide plate 17, the guide plate 17 is in the shape of a truncated conical surface, and the truncated conical surface is a surface formed by cutting off the vertex angle of the conical surface by a horizontal plane. The hole at the top of the guide plate 17 is a communication channel between the first-stage mixing reaction chamber 13 and the second-stage mixing reaction chamber 18, meanwhile, a stirring blade 2 is also arranged in the area near the hole at the top of the guide plate 17, and the stirring blade 2 is driven by a driving motor 1 arranged at the top of the tank. The inboard lower part of guide plate 17 is provided with annular water distribution passageway 14, water distribution passageway 14 below symmetry is provided with the several inlet opening 10, be connected with inlet tube 8 on the guide plate 17, inlet tube 8 and water distribution passageway 14 intercommunication.
Preferably, a guide plate 17 is arranged at the top of the primary mixing reaction chamber 13, the guide plate 17 is in the shape of a truncated cone, a partition plate I4 is vertically arranged at the edge of the inner side of the guide plate 17, and a partition plate II 5 is arranged between the partition plate I4 and the secondary mixing reaction chamber 18; the partition plate I4 is positioned between the partition plate II 5 and the secondary mixing reaction chamber 18. Water in the secondary mixing reaction chamber 18 overflows from the top of the partition plate I4, enters a channel between the partition plate I4 and the partition plate II 5, and then flows out from the lower part of the partition plate II 5. This increases the flow path of the water stream, providing more ample time for thorough mixing of the water with the flocculant and settling of the precipitate. The lower part of the inner side of the guide plate 17 is provided with an annular water distribution channel 14, a plurality of water inlet holes 10 are symmetrically arranged below the water distribution channel 14, the guide plate 17 is connected with a water inlet pipe 8, and the water inlet pipe 8 is communicated with the water distribution channel 14.

A plurality of layers of porous baffles 11 are horizontally arranged in the first-stage mixing reaction chamber 13, the porous baffles 11 are circular, and the positions of the porous baffles 11 in the horizontal direction are positioned in the middle of the first-stage mixing reaction chamber 13. The porous baffle 11 is structured as shown in fig. 3 to 5, through holes 112 protruding downwards are arranged on the porous baffle 11 in a periodic arrangement manner, specifically, from a top view or a bottom view, the arrangement form of the through holes 112 is a two-dimensional close-packed arrangement form with a certain interval between adjacent through holes 112. The through holes 112 protruding downward form a cylindrical body, the diameter of the cylindrical body gradually increases from bottom to top, so that a triangular area between three adjacent through holes 112 forms a closed portion 111, the closed portion 111 protrudes upward from an upper view, and correspondingly, the closed portion 111 is in an upward recessed state from a lower view. The positions of the through holes 112 on two adjacent layers of porous baffles 11 are staggered, and the position of one through hole 112 corresponds to the closed part 111 of the adjacent porous baffle 11.
In the operation of the present embodiment, since the suspension layer of the solid particles of the sludge is mainly located in the middle-lower region of the primary mixing reaction chamber 13, the porous baffle 11 can effectively react with the solid particles floating upward excessively, and the action mode of the porous baffle is mainly to leave the through holes 112 for the water flow to pass through. The area between the through holes 112 is a closed portion 111, and the closed portion 111 is protruded upward from the upper view, and correspondingly, the closed portion 111 is in an upward recessed state from the lower view. In this case, when the floating solid particles enter the sealing portion 111 and are obstructed by the porous barrier, they can only move downward in the turning direction, and due to the inertia, the downward moving solid particles can not easily enter the side through holes 112 any more, so that the floating solid particles at the corresponding position of the sealing portion 111 can be effectively blocked. However, since the positions of the through holes 112 in the two layers of porous baffles 11 adjacent to each other are staggered, the solid particles floating up through the positions of the through holes 112 correspond to the closed portions 111 of the previous layer of porous baffles 11, and are blocked and settle down. From the top perspective, the closed portion 111 is in an upwardly convex shape, and the arc surface of the sidewall thereof cannot stably fix the solid particles, but only guides the solid particles to settle below the perforated barrier 11. Thus, the structure of the perforated barrier 11 is capable of blocking the floating of solid particles without blocking the settling of solid particles and the rising of water flow. The result is an effective reduction in the amount of sludge solids entering the secondary mixing chamber 18 and the return channel 9 with the water flow. The solid particles or suspended matters are reduced to enter the overflow port 6 along with the water flow, thereby improving the quality of the clear water collected by the overflow port 6.
preferably, the through hole 112 protrudes downwards to form a cylindrical body, and a plurality of strip-shaped holes 113 are longitudinally arranged on the side wall of the cylindrical body. Therefore, the area of water passing through the porous baffle 11 can be increased, but the effect of preventing the solid particles from floating up is reduced to a certain degree, and the technical personnel in the field can select setting or not setting according to the floating up condition of the solid particles in the actual process.
