In the sewage treatment plant, the mixture of sludge and water produced after preliminary treatment is called sludge tailwater. These sludge tailwaters need to be further treated to meet the discharge standards.

[0003] For example, in a sludge tailwater treatment pool with patent publication number CN214990354U, the design of the second stirring shaft and multiple first stirring shafts effectively ensures the stirring area and efficiency inside the box, and can fully stir the sludge tailwater inside the box; the first stirring shaft is a hollow tube structure, and the outer wall is provided with a first drainage hole, and the rotating shaft of the second stirring shaft is a hollow tube structure, and the outer wall is provided with a second drainage hole, and in conjunction with the first rotating joint, the second rotating joint, and the pump body, the corresponding purification agent solution can be supplied to the inside of the box during the rotation of the first stirring shaft and the second stirring shaft, so that the agent and the sludge tailwater can be fully mixed and reacted, and rapid and effective purification treatment can be carried out.

[0004] After the above-mentioned equipment injects the sludge tail water into the box, it adds a purification agent solution and stirs the sludge tail water to mix it with the purification agent solution to achieve the purpose of purifying the sludge tail water. However, the purification agent solution can only purify the toxic substances in the sludge tail water, and cannot decompose impurities such as suspended solids in the sludge tail water.

[0025] The filtering mechanism 2 includes two ear plates 201, both of which are fixedly mounted on the outer wall of the treatment tank 101, and a threaded rod 203 is rotatably mounted between the two ear plates 201, a second motor 202 is fixedly mounted on the bottom of one of the ear plates 201, one end of the output shaft of the second motor 202 passes through the ear plate 201 and is fixedly connected to the threaded rod 203, a bracket 204 is connected to the outer wall of the threaded rod 203 by a threaded sliding sleeve, a connecting rod 205 is fixedly connected to the top and bottom ends of the bracket 204, an annular plate 206 is fixedly mounted on the bottom of the connecting rod 205, a filter screen 207 for filtering impurities is arranged on the inner wall of the annular plate 206, and a stirring assembly for mixing sludge tail water and a treatment agent is arranged in the treatment tank 101.

[0026] It should be noted that when in use, the sludge tail water is injected into the treatment tank 101 through the water inlet pipe 102, and then the disinfectant and flocculant are added, and the first motor 109 is started to drive the rotating rod 110 and the stirring rod 111 to rotate, so as to mix the sludge tail water with the disinfectant and flocculant, disinfect the sludge tail water and flocculate the impurities therein. After the treatment is completed, the second motor 202 is started to drive the threaded rod 203 to rotate, and the bracket 204 and the connecting rod 205 can be driven to slide downward through the thread, thereby driving the annular plate 206 and the filter screen 207 to slide downward.

After the filter screen 207 slides downward to the end, the first electric valve 105 is started, and the drain pipe 104 is opened to discharge the sludge tail water without impurities. After most of the sludge tail water is discharged, the second electric valve 107 is started, and the sewage pipe 106 is opened to discharge the filtered impurities.

[0027] An observation window 103 is provided on the outer wall of the processing tank 101 , and tempered glass is arranged inside the observation window 103 .

[0037] Working principle: When in use, the sludge tail water is injected into the treatment tank 101 through the water inlet pipe 102, and then the disinfectant and flocculant are added, and the first motor 109 is started to drive the rotating rod 110 and the stirring rod 111 to rotate, so as to mix the sludge tail water with the disinfectant and flocculant, disinfect the sludge tail water and flocculate the impurities therein. After the treatment is completed, the second motor 202 is started to drive the threaded rod 203 to rotate, and the bracket 204 and the connecting rod 205 can be driven to slide downward through the thread, thereby driving the annular plate 206 and the filter screen 207 to slide downward. When the filter screen 207 slides downward, the flocculated impurities will be filtered below. After the filter screen 207 slides downward to the end, the first electric valve 105 is started, and the drain pipe 104 is opened to discharge the sludge tail water without impurities.
