Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and more specifically, to a microbial mixed treatment device for sludge treatment. Background Technology

[0002] Activated sludge refers to the collective term for microbial communities and the organic and inorganic substances they adhere to. This type of activated sludge requires a full reaction with microorganisms during treatment and is a commonly used method for improving water quality.

[0003] A search revealed that utility model patent CN222219299U discloses a microbial mixing and treatment device for activated sludge treatment. The device includes a treatment tank, a feed frame fixedly connected to the top of the tank, a discharge pipe fixedly connected to the right side of the tank, and support legs fixedly connected to the bottom of the tank. An internal stirring mechanism is provided within the tank, and a screening mechanism is provided inside the feed frame. The stirring mechanism includes a fixed frame, a motor, a first rotating rod, a stirring rod, a first bevel gear, a first connecting rod, a second bevel gear, and a second rotating rod. This microbial mixing and treatment device for activated sludge treatment, with its stirring mechanism, achieves more uniform mixing of activated sludge and wastewater, resulting in better mixing efficiency and improved wastewater treatment efficiency. The screening mechanism prevents activated sludge from accumulating into clumps, ensuring more even distribution and facilitating mixing between the activated sludge and wastewater.

[0004] However, the aforementioned patent has the following shortcomings: although the stirring rod can be driven to rotate in the opposite direction through the transmission of components such as the first bevel gear and the second bevel gear, the sludge entering the tank will affect the transmission between the first and second bevel gears, thus affecting the smooth operation of the equipment; in addition, after the activated sludge is screened through the sieve plate, the sludge remaining on the sieve plate is not easy to process, and it also affects the amount of sludge added to the tank. Therefore, we propose a microbial mixed treatment device for sludge treatment. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a microbial mixing treatment device for sludge treatment.
