Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a device for treating garbage leachate by utilizing a microbial agent. Background Art

[0002] Leachate usually refers to the liquid generated during the garbage dumping process. These liquids mainly come from the sewage released during the decomposition and compression of garbage and the sewage pressed out by the garbage dump. These leachates contain various harmful substances, such as organic waste, heavy metals, chemicals, etc., which pollute the environment. Managing these leachates is crucial to environmental protection, and usually requires filtration and treatment of landfills to prevent them from polluting groundwater and soil.

[0003] When the landfill leachate biochemical system is in operation, it will often encounter large fluctuations in the incoming water quality. When the water quality fluctuates, the exclusive bacteria species in the biochemical system will be impacted, causing a large amount of activated sludge to be lost and die. If the biochemical system relies solely on its own recovery, it will affect the water treatment system's treatment volume and the recovery time will be longer. Utility Model Content

[0086] Optimized control of oxygen supply: The equipment is equipped with a blower and an aerator. By controlling the oxygen supply, it can ensure that the oxygen demand of the microorganisms in the aerobic culture tank 5 is met, thereby promoting the aerobic biodegradation process. At the same time, the use of an aeration device can also improve the dissolution efficiency of oxygen, further enhancing the efficiency and stability of the treatment system.

[0087] Precise delivery of nutrient dosing system: The equipment is also equipped with a nutrient dosing device 7, which can add necessary nutrients to the treatment process in a timely manner according to the needs of the system. This precise nutrient dosing method can ensure the health and stability of the microbial community and help improve the effect and speed of wastewater treatment.

[0088] Flexible control of the water inlet pipeline: By controlling the valve 8 on the water inlet pipeline, the operator can adjust the water inlet flow rate according to the actual situation to adapt to different treatment requirements or changes in treatment effects. This flexible pipeline control method can ensure the stable operation of the system and improve its processing capacity and flexibility.

[0089] Rapid response of the inoculation pump 9 system: When the system is impacted by external factors or the number of bacterial strains is insufficient, the inoculation pump 9 system equipped with the equipment can quickly introduce new bacterial strains into the treatment system to help the system return to a stable operating state. This rapid response capability can effectively reduce the impact of changes in the external environment on the treatment system and ensure the continuous and efficient operation of the system.
