Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection devices, and particularly relates to a garbage leachate treatment device for environmental protection engineering. Background Art

[0002] Garbage leachate is derived from the water contained in the garbage itself processed in the landfill site, as well as the rain and snow water that seeps into the storage area from the ground and forms after passing through the filtering effect of the garbage accumulation layer and the soil layer. This kind of sewage contains a large amount of suspended debris and toxic and harmful pollutants, and its composition is extremely complex. If the garbage leachate is directly discharged into the ground or seeps into the groundwater without proper treatment, it will cause serious secondary pollution to the environment and pose a serious threat to surface water and groundwater. Therefore, it is necessary to design a garbage leachate treatment device;

[0003] When the existing garbage leachate treatment device treats the filtered impurities and suspended matters, the impurities and suspended matters near the inner wall of its box body will adhere to the inner wall and are inconvenient to clean. Long-term accumulation will affect the service life and treatment effect of the filter plate. Therefore, it is necessary to design a leachate treatment device that can facilitate the rapid cleaning of impurities and suspended matters on the inner wall of the box body.
