[0002] Human life and production are inseparable from water resources. The sewage generated in our life and production process has complex components. If it is discharged directly, it will seriously pollute the environmental water sources and cause damage to the natural environment. In the long run, it will also affect human life and development. Therefore, for the sustainable development of mankind, domestic and production wastewater must be treated by equipment and can only be discharged after meeting the standards.

It includes a decontamination mechanism and a filter residue mechanism; large particles of pollutants will be intercepted by the filter residue plate, and then the second servo motor works to make the filter residue plate drive the large particles of pollutants to move to the top outlet of the sewage tank under the action of the baffle, and stop when it moves to the designated position at the upper end of the sewage tank. The pollutants inside the sewage tank can be cleaned through the slag discharge mechanism, and the second servo motor works to make the filter residue plate drive the plug column to descend, so that the plug column drives the water barrier to press the press switch, and then the fourth servo motor drives the card block to fix the plug column, and then the second servo motor is manually controlled to drive the filter residue plate to rise, thereby driving the silt on the upper surface of the mud plate to move to the top outlet of the sewage tank, at this time The staff can easily clean the sediment;

A plurality of sedimentation spaces 401 are provided inside the sedimentation purification area 400 through the third partition plate 103. The plurality of sedimentation spaces 401 flow into each other. Specifically, when in use, the sewage to be treated enters the water inlet area 200 and is preliminarily filtered through the filter cylinder 203 inside it. The sewage after preliminarily filtration flows into the dosing mixing area 300 through the first overflow port 104. When flowing into the dosing mixing area 300, it drives the transmission component 303 provided inside it to rotate, and then drives the flocculant inside the storage hopper 302 to be spread into the dosing mixing area 300. The stirring component 304 is started to stir and mix the flocculant and the sewage. The sewage mixed with the flocculant enters the sedimentation purification area 400 through the second overflow port 105. A plurality of sedimentation spaces are formed in the sedimentation purification area 400 through the third partition plate 103. The sewage flows slowly in the sedimentation space to settle the suspended matter.

[0036] Reference Figure 1-3, an inlet pipe 201 and an outlet pipe 202 are symmetrically provided on the outer wall of the pool body 100, one end of the filter screen cartridge 203 is sleeved on the outer wall of the water inlet pipe 201, and the other end passes through the outlet pipe 202 and is detachably connected to the outlet pipe 202 through a flange 204, and a first sewage pipe 205 is provided on the end of the flange 204 away from the outlet pipe 202, and a first control valve 206 is provided on the first sewage pipe 205. Specifically, one end of the filter screen cartridge 203 is sleeved on the outer wall of the water inlet pipe 201, and the other end is detachably connected to the outlet pipe 202 through a flange 204, which is convenient for regular cleaning and maintenance of the filter screen cartridge 203. Secondly, when in use, sewage passes through the water inlet pipe 2 01 enters the interior of the filter mesh cylinder 203, and then is filtered through the filter mesh cylinder 203 and enters the water inlet area 200. The water inlet pipe 201 and the water outlet pipe 202 are located at the same level. Therefore, when the sewage enters the interior of the filter mesh cylinder 203 through the water inlet pipe 201, it will have a certain impact force, which can then have a certain flushing effect on the filter mesh cylinder 203, and can effectively avoid its blockage. Secondly, under the impact of the water flow, the filtered impurities will flow to the outlet pipe 202. When a lot of impurities accumulate inside the filter mesh cylinder 203, open the first control valve 206, and the filtered impurities can be conveniently cleaned under the impact of the water flow.

[0037] Reference Figure 6-9 The storage hopper 302 is provided with a material guide shell 306 at one end passing through the mounting frame 301. A material diverter assembly 305 is provided inside the material guide shell 306 for spreading the flocculant into the dosing and mixing zone 300 under the drive of the transmission assembly 303. The flocculant in the storage hopper 302 can be evenly spread into the dosing and mixing zone 300 through the provided material diverter assembly 305, and mixed with the sewage in cooperation with the provided stirring assembly 304.

[0038] Reference Figure 4 、 Figure 8 and Figure 9 The transmission assembly 303 includes a rotating shaft 3031 arranged inside the dosing and mixing zone 300, blades 3032 arranged on the outer wall of the rotating shaft 3031, and a transmission belt 3033 arranged between the rotating shaft 3031 and the material shifting assembly 305 through a pulley.

[0039] The material-dispensing assembly 305 includes a transmission shaft 3051 that passes through the material guide shell 306 and is rotatably connected to the inside of the dosing and mixing zone 300, and a plurality of material-dispensing plates 3052 that are arranged on the outer wall of the transmission shaft 3051 and located inside the material guide shell 306. A discharge port 3053 is provided at the bottom of the material guide shell 306. Through the transmission assembly 303, it can rotate with the flow rate of the water flow, thereby driving the transmission belt 3033 to rotate, and then driving the material-dispensing plate 3052 to rotate, and the flocculant inside the storage hopper 302 is broadcast to the inside of the dosing and mixing zone 300. This process will automatically add a certain amount of flocculant according to the amount of sewage entering the dosing and mixing zone 300 to avoid excessive or insufficient addition of flocculant.

[0040] Reference Figure 1-4 The stirring component 304 includes a stirring part 3041 arranged on the mounting frame 301 and an aeration component 3044 arranged at the bottom of the dosing mixing zone 300. Furthermore, the stirring component 3041 includes a driving motor 3042 arranged on the top of the mounting frame 301, a reducer installed at the output end of the driving motor 3042, and an agitator 3043 connected to the output end of the reducer and passing through the mounting plate and extending downward to the inside of the dosing mixing zone 300. The aeration component includes an air pump and an aeration pipe 3045 connected to the output end of the air pump and arranged inside the dosing mixing zone 300. The flocculant and sewage are mixed and stirred by the stirring component 3041, and the aeration component is used to increase the fluidity of the water body, further mix it, and make the mixing more uniform and thorough.

[0041] Reference Figure 4-7 A buffer guide component 402 is provided in the first sedimentation space 401. The buffer guide component 402 includes a horizontal leakage net 403 provided in the sedimentation space 401 and a guide net 404 obliquely provided at the bottom of the horizontal leakage net 403. The buffer guide component 402 can buffer the sewage entering the sedimentation space 401, so that the sewage flows slowly in the sedimentation space 401, thereby improving the sedimentation effect.

[0042] Several partitions are provided with sewage circulation ports 405, and adjacent sewage circulation ports 405 are staggered with each other up and down. The sewage circulation ports 405 located below the partitions are higher than the bottom of the tank body 100, and the sewage circulation ports 405 located above are lower than the top of the tank body 100. Several sedimentation spaces 401 are provided with second sewage pipes 406, and the second sewage pipes 406 are provided with second control valves. The sewage circulation ports 405 between adjacent sedimentation spaces 401 are staggered up and down, so that the sewage constantly changes its flow direction during the flow process. Slowing down the flow rate of the sewage can better improve the sedimentation effect. Each sedimentation space is provided with an independent sewage pipe and control valve, which makes the sewage discharge operation more flexible and convenient, and the sediment can be selectively discharged according to actual needs.

[0043] A filter assembly 407 is provided in one of the sedimentation spaces 401. The first filter assembly 407 includes a supporting frame 408 that is detachably provided in the sedimentation space 401 through a positioning column. A filter material component 409 is provided in the supporting frame 408, and the supporting frame 408 cooperates with the sewage flow port 405 located above. The detachable filter material component 409 can not only filter and purify the sewage, but also facilitate regular cleaning and maintenance through the detachable connection design.

[0044] A mounting ring 410 is provided in a sedimentation space 401 at the tail end, and an inclined tube filler 411 is detachably installed on the mounting ring 410. A drain outlet 106 for discharging purified water resources is provided at the tail end of the pool body 100. The height of the inclined tube filler 411 is lower than the height of the drain outlet 106. The inclined tube filler 411 is further filtered and purified through the fine particulate impurities in the sewage, thereby improving the purification effect of the sewage. The detachable structure is convenient for replacement and cleaning, and the filtered sewage is discharged through the drain outlet 106.

[0045] Specifically, when the present ecological environment purification sewage treatment system is in use: sewage enters the interior of the filter cylinder 203 through the water inlet pipe 201, and then passes through the filter cylinder 203 for filtering and enters the interior of the water inlet area 200. The filter cylinder 203 provided can achieve a preliminary filtering effect. When the sewage enters the interior of the filter cylinder 203 through the water inlet pipe 201, it will have a certain impact force, which can play a certain flushing effect on the filter cylinder 203, and can effectively avoid the blockage of the filter cylinder. Secondly, under the impact of the water flow, the filtered impurities will flow to the outlet pipe 202. When a lot of impurities accumulate inside the filter cylinder 203, the first control valve 206 is opened, and the filtered impurities can be conveniently cleaned under the impact of the water flow. Then the sewage inside the water inlet area 200 will enter the interior of the dosing and mixing area 300 through the first overflow port 104;

[0046] The transmission assembly 303 cooperates with the first overflow port 104, so the sewage entering the dosing mixing area 300 through the first overflow port 104 will act on the blade 3032, thereby driving the blade 3032 and the rotating shaft 3031 to rotate, and the transmission belt 3033 will drive the transmission shaft 3051 connected thereto to rotate, and then drive the material plate 3052 connected to its outer wall to rotate, thereby spreading the flocculant into the dosing mixing area 300. Since the blade 3032 is affected by the sewage water flow rate and water flow speed of the first overflow port 104, when the sewage water flow rate is When the pressure is greater than 0.05, the amount of flocculant spread will increase accordingly. When the flow rate of sewage is slow, the amount of flocculant spread will also decrease accordingly. Therefore, it can be adaptively adjusted according to the flow rate of sewage. Then, the drive motor 3042 is started to drive the agitator 3043 connected to its output end to rotate, and the flocculant and sewage are stirred and mixed. Furthermore, by starting the air pump for aeration operation, increasing the fluidity of the sewage can further improve the mixing effect of the sewage and the flocculant, and improve the purification effect of the sewage. The evenly mixed sewage flows into the sedimentation purification area 400 through the second overflow port 105 at the top of the second partition plate 102.

[0047] The sedimentation purification area 400 is divided into multiple sedimentation spaces 401 by the third partition plate 103. The sewage gradually settles in the sedimentation space 401 to remove suspended matter and impurities. The buffer guide component 402 provided in the first sedimentation space 401 further slows the water flow rate and promotes sedimentation. The sewage flow openings 405 between adjacent sedimentation spaces 401 are staggered vertically, so that the sewage constantly changes its flow direction during the flow process, thereby improving the sedimentation effect.

[0048] In the several sedimentation spaces 401, at least one space is provided with a filter component 407 for deep filtering of the sewage. The filter component 407 includes a supporting frame 408 and a filter material component 409. The filter material component 409 filters the sewage and removes fine impurities. A second sewage pipe 406 is provided above each sedimentation space 401 for discharging sediment. In the sedimentation space 401 at the tail end, the sewage that has been fully precipitated and filtered meets the discharge standard and is discharged through the drain outlet 106.
