[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 A heavy metal wastewater treatment pool comprises a box body 1, a filter box 24 is installed at the bottom of the box body 1; a water injection pipe 3 is installed on the box body 1, a rotating drum 4 is arranged in the box body 1, a plurality of regularly distributed through holes 5 are opened on the rotating drum 4, a stirring rod 6 is installed on the outer wall of the rotating drum 4, a driving component for driving the rotating drum 4 to rotate is installed on the box body 1, a monitoring component is arranged in the rotating drum 4 for monitoring the injection amount of heavy metal wastewater in the box body 1, an injection component is arranged on one side of the box body 1 for injecting flocculant, a drain pipe 21 is arranged at the bottom of the box body 1, a valve 22 is arranged on the drain pipe 21, and a drain pipe 26 is arranged on one side of the bottom of the filter box 24.

[0019] The utility model injects heavy metal wastewater into the box body 1 through the water injection pipe 3, and monitors the injection amount of the heavy metal wastewater in the box body 1 through the monitoring component. When the injection is completed, the amount of flocculant injected by the injection component is adjusted according to the monitoring data of the monitoring component, so that the injection amount of the flocculant can be adjusted according to the injection amount of the heavy metal wastewater, avoiding the problem of excessive or insufficient flocculant injection.

[0020] In one case of this embodiment, a controller 2 is provided on one side of the box 1 .

[0021] In one case of this embodiment, the monitoring component includes a limit frame 12 installed on the box body 1, and a movable rod 11 is slidably provided on the limit frame 12. A float 10 is installed at one end of the movable rod 11 extending into the rotating drum 4, and a first distance sensor 13 is installed in the rotating drum 4.

[0022] In one case of this embodiment, the injection component includes a fixed cylinder 14 installed on one side of the box body 1, a storage chamber 15 is opened in the fixed cylinder 14, the fixed cylinder 14 is connected to the box body 1 through a delivery pipe 19, an addition pipe 20 is provided on one side of the storage chamber 15, a piston 16 is slidably provided in the storage chamber 15, a multi-stage hydraulic rod 17 connected to the piston 16 is installed in the fixed cylinder 14, and a second distance sensor 18 is provided in the storage chamber 15.

[0023] In one case of this embodiment, two opposing elbows 23 are installed at the bottom of the drain pipe 21. When the drain pipe 21 discharges heavy metal wastewater containing sediment in the box body 1, the wastewater will flow out from the elbows 23. Since the two elbows 23 are opposite to each other, the wastewater flowing out of the two elbows 23 will collide with each other, thereby reducing the impact force of the wastewater discharged from the drain pipe 21 on the arc filter screen, and preventing the wastewater discharged from the drain pipe 21 from directly falling and impacting the arc filter plate 25, thereby causing smaller sediments to be washed through the arc filter plate 25, resulting in better use effect.

[0024] In one case of this embodiment, the driving component includes a motor 9 installed on the box body 1, and a second gear 8 is installed at the output end of the motor 9. A first gear 7 engaged with the second gear 8 is installed on the rotating drum 4. When the motor 9 is started, the rotating drum 4 can be driven to rotate through the engaged first gear 7 and second gear 8.

[0025] The working principle of the present invention is as follows: when in use, heavy metal wastewater is injected into the box body 1 through the water injection pipe 3. As the amount of heavy metal wastewater injected into the box body 1 gradually increases, under the action of the float 10, the movable rod 11 will rise along the limit frame 12. At the same time, the first distance sensor 13 will continuously monitor the distance from the float 10 and transmit the data to the controller 2. When the injection of heavy metal wastewater is completed, the data of the distance sensor received by the controller 2 is proportionally calculated to calculate the distance that the piston 16 needs to move, and then the multi-stage hydraulic rod 17 is started, thereby driving the piston 16 plate to move, pressing the flocculant in the storage chamber 15 into the delivery pipe 19, and finally entering the box body 1 and mixing with the heavy metal wastewater. Mixing, wherein the second distance sensor 18 will continuously monitor the distance between it and the piston 16. When the monitored distance reaches the value calculated by the controller 2, the multi-stage hydraulic rod 17 will stop, so that a fixed amount of flocculant can be injected into the box body 1, which can avoid the problem of too much or too little flocculant being injected. Then, the driving component is started to drive the drum 4 to rotate, so that the stirring rod 6 can stir and mix the heavy metal wastewater and the flocculant, and then the precipitation treatment can be fully carried out. Then, the valve 22 is opened, and the heavy metal wastewater containing sediment in the box body 1 will be discharged from the drain pipe 21 into the filter box 24, and the sediment in the heavy metal wastewater will be filtered through the arc filter plate 25, and finally discharged from the drain pipe 26.
