[0044] In the present invention, the air stripping device 10-3 is a prior art, and is preferably an air stripping pump, which will not be further described in the present invention. In the present invention, the air stripping device 10-3 and the sludge control valve 10-8 are both connected to the control system by electrical signals.

[0045] The present invention is provided with an air compression pipe 10-4, which utilizes the air source as kinetic energy, replacing the mud lifting pump and the water suction well. The operation is simple, flexible and convenient, and the air flow rate can be adjusted to adjust the mud return flow rate, thereby achieving the goal of high-efficiency and low-consumption wastewater treatment.

[0046] Preferably, the sludge discharge pipe 10-7 is provided with a purge air pipe 11, the purge air pipe 11 is provided with a purge pipe control valve 11-1, and the connection point between the purge air pipe 11 and the sludge discharge pipe 10-7 is located at the front end of the sludge control valve 10-8.

[0049] In the present invention, the water inlet pipe 2 is communicated with the upflow reaction condensation zone 5 , a pipeline mixer 3 is arranged on the water inlet pipe 2 , and the pipeline mixer 3 is communicated with the coagulant dosing pipe 4 . The mixed water from the user sewage passes through the water inlet pipe 2, and after the coagulant is added, it flows into the upflow reaction coagulation zone 5 in a tangential direction. The kinetic energy of the inlet water is used for swirling stirring and mixing reaction to quickly form alum floccules. The water that is not suitable for precipitation rises to the coagulation zone through the water distribution port baffle 5-1. The generated mud settles in the mud bucket 5-5 and is discharged through the mud discharge pipe 5-7. The mixed water that rises to the coagulation zone reacts with the return sludge and the added flocculant (micro-vortex flocculation ball 5-3). Under the action of the micro-vortex flocculation ball 5-3, they are adsorbed by each other to form large suspended particles that overflow into the guide groove 6, and flow evenly into the filler area 7 through the baffle plate 6-1 for rapid separation. In order to prevent the mud bucket 5-5 and the mud discharge pipe from being blocked, a purge air pipe 11 is provided in front of the mud control valve 5-8.

[0050] In the present invention, the coagulant, sewage, and return sludge from the concentration zone 10 added by the pipeline mixer 3 are mixed and reacted under the action of the micro-vortex flocculation balls 5-3 in the coagulation zone, and the coagulated water forms large suspended particles and flows evenly into the packing zone 7 through the baffle 6-1 of the guide groove 6. The packing zone 7 is equipped with an inclined plate packing 7-1. According to the shallow sedimentation theory of the inclined plate, the clear and turbid water is quickly separated, and the clear water rises to the clear water zone 8 and flows into the water collection tank 9 through the triangular overflow weir drainage trough 8-1, and is discharged through the siphon outlet 9-1. The mud sinks to the mud storage hopper 10-1 of the concentration zone 10, and part of the sludge is lifted and returned to the upflow reaction coagulation zone 5 through the air lift device 10-3, and part of it is discharged through the sludge discharge port 1-6. In the present invention, the packing zone 7 is preferably an inclined plate or inclined tube packing. A plurality of inclined plates or inclined tubes are filled into the packing zone 7.

[0051] In the present invention, the upper part of the main body 1 is a square structure, and the upper part adopts a square structure.

To facilitate mud discharge, the mud buckets 5-5 on both sides adopt an inverted ladder structure, and the mud discharge at the lower part of the upflow reaction condensation zone 5 adopts an inverted truncated table structure. The lower half of the device presents an inverted trapezoidal structure as a whole.

[0052] In the present invention, after the coagulant added from outside is mixed with the user's water, it rises to the coagulation zone through the cyclone reaction, and then reacts with the return sludge and the micro-vortex flocculation balls in the coagulation zone. Under the action of the micro-vortex flocculation balls, the flocculation ability is enhanced, the reaction time is shortened, the water production is increased, and the effluent water quality is stabilized. The sludge return effect in the present invention allows the reagents remaining in the sludge to be fully utilized, which saves the reagents and improves the effluent water quality. In the present invention, a siphon outlet 9-1 is set to produce a siphon outlet effect, and the siphon principle is used to effectively block the air from entering the outlet pipe 9-2, solving the problem of water collection tank backlogging and outlet pipe blockage caused by air resistance caused by the original gravity drainage. The single grid of the inverted trapezoidal mud storage hopper 10-1 in the concentration area 10 is optimized to two grids, equipped with two mud discharge ports, and a purge air pipe 11 is added before the mud control valve 10-8 to reduce the single grid mud storage volume, improve the sludge flowability, and solve the mud discharge pipe blockage problem.

[0053] The present invention is a process integrating mixing, flocculation and sedimentation, with compact structure, small footprint, slurry reflux, saving of reagents, enhanced flocculation effect, accelerated separation speed, increased water production and reduced equipment investment.

[0054] The non-powered energy-saving device of the present invention utilizes the kinetic energy of the incoming water to perform swirl stirring, replacing mechanical stirring, strengthening the flocculation effect, and saving reagents. The present invention is provided with an air compression pipe 10-4, utilizing the air source as kinetic energy, replacing the mud lifting pump and the water absorption well, and is simple to operate, flexible and convenient, and can adjust the air flow to adjust the size of the mud return flow, thereby achieving the goal of high-efficiency and low-consumption wastewater treatment.

[0055] Embodiment 3: Based on Example 1 or 2, this embodiment provides an intelligent sewage purification method, and the specific steps are as follows: The sewage from the user is mixed with the coagulant added through the coagulant dosing pipe 4 in the pipeline mixer 3 through the water inlet pipe 2, and then flows into the upflow reaction coagulation zone 5 in a tangential direction, rises to the upper coagulation zone through the cyclone reaction, and fully reacts with the return sludge from the concentration zone 10 in the coagulation zone; under the action of the micro-vortex flocculation balls 5-3 in the coagulation zone, they collide and adsorb with each other to form large suspended particles, which are evenly distributed through the baffle 6-1 of the guide groove 6 and flow into the sedimentation zone for rapid separation; the reaction zone at the bottom of the upflow reaction coagulation zone 5 produces mud which sinks into the mud bucket 5-5 and is discharged through the mud discharge pipe 5-7.

[0056] In the present invention, the sludge water formed by the reaction and condensation in the upflow condensation zone 5 is evenly distributed in the inclined plate filling zone 7 through the guide groove 6. According to the inclined plate shallow sedimentation theory, the water rises along the inclined plate (or inclined pipe) to the clear water zone 8, and converges to the water collecting tank 9 through the triangular overflow weir drainage groove 8-1, and flows into the next treatment process through the siphon outlet 9-1 and the outlet pipe 9-2. The separated sludge slides down to the trapezoidal sludge storage hopper 10-1 in the concentration zone 10 under the action of gravity, and part of the sludge is lifted by the air stripping device 10-3 through the sludge return pipe suction port 10-2, and refluxed to the upflow reaction condensation zone 5 through the sludge return pipe 10-5 to participate in the reaction, and part of the sludge is discharged through the sludge discharge outlet 10-6 and the sludge discharge pipe 10-7.
