Description

Technical Field

[0001] The utility model relates to the technical field of leachate treatment, in particular to a leachate biochemical degradation treatment device. Background Art

[0002] Leachate refers to the sewage that seeps out during the stacking and landfilling of garbage due to fermentation, rainwater erosion, and immersion in surface water and groundwater. In the biochemical degradation treatment of the leachate, cationic polyacrylamide needs to be added to the leachate. Cationic polyacrylamide is usually used in combination with other treatment agents (such as polyaluminum chloride) to improve the treatment efficiency through synergistic effects. The combination of the two can more effectively remove pollutants in the garbage leachate and reduce the difficulty and cost of treatment.

[0003] The existing patent announcement number CN209583840U discloses a garbage leachate treatment device, which includes a scraper and an impurity collection box. The leachate is injected through the water inlet and enters the box through the filtering mechanism; the agent in the medicine storage box is injected at the same time; the injection is stopped after the specified amount of leachate and agent is injected; the impurity removal mechanism drives the scraper to move back and forth through the cylinder; the scraper drives the stirring rod to stir, accelerating the reaction between the agent and the leachate; part of the scraper is located in the leachate, and part is located above the liquid surface; a groove is left on the top of the scraper, and the groove is open at the end away from the cylinder, the open end of the groove is low, and the closed end is high; the scraper hangs the flocs floating on the surface of the leachate into the groove, and flows out through the open end and falls into the impurity collection box; after all the flocs are scraped off, the impurity removal mechanism stops moving, and the leachate settles in the box; after sedimentation, the sediment is discharged through the impurity discharge port.

[0004] In the above-mentioned device, chemicals are used to biochemically degrade the leachate in the leachate, and the flocs in the leachate are cleaned by using a scraper. Since the flocs do not completely float on the surface, the use of the scraper will lead to incomplete cleaning, and the sediment is removed after sedimentation, which takes a long time and affects the leachate treatment effect. In response to the above problems, a leachate biochemical degradation treatment device is proposed. Utility Model Content
