Scrapers 231 are provided on both sides of the stirring rod 23. A motor 24 is connected to the upper end of the stirring rod 23.

[0018] like Figure 1 , Figure 5 and Figure 6As shown, a connecting shaft 152 is provided at the upper center of the mounting plate 151. The connecting shaft 152 passes through the end of the connecting plate 161 away from the filter screen 16. A nut 153 is threaded onto the outer side of the connecting shaft 152 to facilitate the disassembly and assembly of the connecting plate 161 for cleaning of the filter screen 16 connected to the connecting plate 161. The protective cover 17 is detachably connected to the mounting plate 151 to protect the connecting shaft 152 and the nut 153, preventing wastewater from adhering to the nut 153 and the connecting shaft 152, thus reducing the workload of the user in cleaning the above components.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, a first discharge pipe 112 is provided in the lower center of the filter chamber 11. The lower end of the first discharge pipe 112 passes through the interior of the second top plate 211, which facilitates the injection of the filtered wastewater from the filter mechanism 1 into the outer shell 21. A second feed pipe 214 is connected to the upper side of the second top plate 211. A third feed pipe 215 is provided on one side of the second feed pipe 214. The lower end of the third feed pipe 215 is connected to the second top plate 211, which facilitates the user to inject additives into the outer shell 21 through the second feed pipe 214. It is also convenient to re-inject wastewater that fails the water quality test into the outer shell 21 for treatment through the third feed pipe 215.

[0020] like Figure 1 , Figure 2 and Figure 7 As shown, the upper end of the stirring rod 23 is rotatably connected to the second top plate 211, the motor 24 is connected to the second top plate 211, and the second top plate 211 is detachably connected to the outer shell 21, so that the second top plate 211 can provide support for the motor 24 and the stirring rod 23.

[0021] like Figure 1 and Figure 2 As shown, a second discharge pipe 212 is connected to the lower center of the outer shell 21 to facilitate the discharge of wastewater after flocculation and sedimentation from the inside of the outer shell 21. A valve 213 is provided inside the second discharge pipe 212 to facilitate the control of the opening and closing of the second discharge pipe 212.

[0022] like Figure 1 and Figure 2 As shown, a bracket 25 is connected to the outer side of the outer shell 21.

A controller 3 is provided on one side of the bracket 25. The motor 24 and the level gauge 22 are both connected to the controller 3 through power lines and signal lines, which facilitates the use of the controller 3 to control the operation of the motor 24 and helps to transmit the liquid level of the wastewater inside the outer shell 21 measured by the level gauge 22 to the controller 3.

[0023] The textile dyeing wastewater treatment device disclosed in this embodiment, during use, injects the wastewater to be treated into the filter chamber 11 via the first feed pipe 15. The filter screen 16 inside the first feed pipe 15 can initially filter out thread ends and fibers in the wastewater. The wastewater passing through the filter screen 16 is filtered sequentially by the activated carbon plate 13 and the biofilm filter layer 14, and then flows downward through the first discharge pipe 112 into the outer casing 21. The liquid level of the wastewater inside the outer casing 21 is observed and transmitted back to the controller 3 by the liquid level gauge 22. When the liquid level in the outer casing 21 reaches a certain value, the liquid level is adjusted accordingly. When there is sufficient wastewater, stop adding wastewater to the filter chamber 11. Based on the volume of wastewater in the outer shell 21, inject an appropriate amount of additive into the outer shell 21 through the second feed pipe 214. Use the controller 3 to start the motor 24, causing the motor 24 to drive the stirring rod 23 and scraper 231 to rotate, mixing the wastewater and additive evenly. During rotation, the scraper 231 can scrape off impurities in the wastewater adhering to the inner wall of the outer shell 21. Turn off the motor 24, stopping the stirring rod 23 from rotating. Then, proceed according to the reaction requirements. After standing for a period of time, place the original receiving component, such as a bucket, at the lower end of the second discharge pipe 212, open valve 213, and discharge an appropriate amount of wastewater through the second discharge pipe 212 into the receiving component. Then close valve 213 and use the original water quality analyzer to test the water quality of the wastewater in the receiving component. If the water quality is qualified, connect the large-capacity receiving component or sewage pipe to the second discharge pipe 212, open valve 213, and discharge the treated wastewater from the outer casing 21. If the water quality analyzer detects that the wastewater is within acceptable limits... If the wastewater in the receiving component does not meet the discharge standards, the wastewater in the receiving component is poured back into the outer shell 21 through the third feed pipe 215. The settling time is increased or corresponding additives are added as needed, and the stirring rod 23 is rotated by the motor 24 to stir. Then, the receiving component is used for secondary sampling and tested with a water quality tester until the water quality is qualified. The large-capacity receiving component or sewage pipe is connected to the second discharge pipe 212, and the valve 213 is opened to discharge the treated wastewater in the outer shell 21.
