Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to a sedimentation tank sludge treatment device and a treatment method. Background Art

[0002] Sedimentation tanks mainly improve water quality by allowing sewage to settle and precipitate impurities in the water. Impurities accumulate at the bottom of the sedimentation tank for a long time to form thick sludge. In order to maintain the sedimentation effect of the sedimentation tank, the sludge at the bottom of the sedimentation tank needs to be cleaned regularly. When cleaning the sedimentation tank, a large sludge treatment vehicle is generally used to clean the sedimentation tank. First, the water is collected for discharge, and then the sludge is extracted and dehydrated through the dehydration component of the vehicle body before loading. Then the water in the sedimentation tank also contains a large amount of impurities. The extraction process also requires the upper water layer of the sludge to be treated, otherwise direct discharge is likely to cause secondary pollution. Flocculants need to be added to allow the sludge to settle first, and then separated from the sludge. At present, the suction device of the sludge treatment vehicle has a relatively single function and is not easy to handle. Therefore, it is necessary to design a sedimentation tank sludge treatment device and treatment method that is easy to extract and flocculate. Summary of the invention

The mixing blade driven by the servo motor effectively prevents the precipitation of the liquid in the medicine box, ensuring the uniformity and stability of the flocculant. The stirring action of the stirring blade accelerates the mixing of the flocculant and sewage, and improves the treatment efficiency.

[0014] 2. By controlling the start of the solenoid valve and the pump body, the automatic extraction and discharge of the clean water on the upper part of the sedimentation tank is realized. When the water level drops, the entire device drops accordingly, and the folded medicine tube stretches, which is convenient for the subsequent extraction and treatment of sludge. When it comes into contact with the sludge, the mixing action of the stirring blades and the stirring blades prevents the sludge from coagulating and hardening, thereby improving the sludge extraction efficiency. The filter press assembly of the sludge treatment vehicle effectively separates the mud and water by filter pressing, realizing the complete separation of mud and water, which is convenient for the subsequent mud collection and treatment.

9. A treatment method for a sedimentation tank sludge treatment device, characterized in that: A sedimentation tank sludge treatment device according to claim 8 specifically comprises the following steps: S1. Installing the tracks: Install two second tracks (17) at the two ends of the sedimentation tank respectively, ensuring that they are stable and parallel, and slide the first track (1) onto the second tracks (17) to facilitate subsequent movement and adjustment; S2, adding and mixing reagents: opening the cover of the medicine box (141), adding an appropriate amount of flocculating reagent into the medicine box (141), controlling the servo motor (163) to work, and driving the mixing blade (162) to stir the liquid in the medicine box (141) by the rotating shaft (161) to prevent precipitation; S3, adjusting the hard nozzle (73): rotating the rotating disk (77) so that the arc-shaped hole (78) of the rotating disk (77) squeezes the hard nozzle (73) to rotate outward, and the hard nozzle (73) drives the sliding block (72) to move outward, and the second gear (86) on the sliding block is meshed with the inner gear ring (83), and the rotating motor (84) is started to drive the first gear (85) to rotate, thereby driving the inner gear ring (83) and the second gear (86) to rotate, so that the hard nozzle (73) rotates; S4, chemical injection and sewage stirring: start the water pump (142), inject the flocculant in the medicine box (141) into the hard spray pipe (73) through the foldable medicine tube (143) and the connecting tube (144), and then spray it out through the injection head (74). The stirring blade (75) stirs the sewage in the sedimentation tank so that the flocculant and sewage are quickly mixed. At the same time, the rotating motor (84) drives the rotating shaft (152) to rotate through the belt transmission component (153), thereby driving the stirring blade (157) to rotate, thereby enhancing the mixing effect; S5. Equipment movement and regional delivery: The staff can pull the pull rope to move the first slider (2) and all components thereon on the first track (1) so as to deliver the flocculant to be mixed with the sewage in different areas. The staff can also move the first track (1) along the second track (17) to expand the delivery range. S6, standing and draining: After the flocculant is added, all power components are turned off and the system is allowed to stand for a period of time to allow the flocculant to fully act. The liquid inlet solenoid valve on the side wall of the rectangular nozzle (10) is controlled to open, and the liquid inlet solenoid valve at the bottom is closed. The pump body (9) is started to extract the clean water from the upper part through the rectangular nozzle (10) and discharge it through the hard water pipe (4); S7, sludge treatment: When the water level drops to a level close to the sludge, the solenoid valve at the bottom of the rectangular nozzle (10) is controlled to open, and the rotating motor (84) and the pump body (9) are started. The upper sludge is extracted through the rectangular nozzle (10) and enters the sludge treatment vehicle through the hard water pipe (4). The sludge and water are filtered by the filter press assembly of the sludge treatment vehicle to separate the sludge and water. The filtered sludge is collected and treated uniformly.
