Description
Technical Field
[0001] This utility model belongs to the technical field of sewage treatment equipment, specifically relating to a mobile cultivation vehicle for nitrifying bacteria in sewage treatment. Background Technology
[0002] The mobile nitrifying bacteria cultivation vehicle for wastewater treatment is an integrated, mobile device for the cultivation and application of nitrifying bacteria in wastewater treatment. It is mainly used to efficiently cultivate nitrifying bacteria and flexibly deploy them in different wastewater treatment scenarios. The mobile nitrifying bacteria cultivation vehicle for wastewater treatment achieves efficient cultivation and flexible deployment of nitrifying bacteria through integrated design. Its workflow can be divided into five stages: preparation, start-up, cultivation, transfer, and maintenance.
[0003] CN212560229U discloses a nitrifying bacteria cultivation chamber for a water filtration system, comprising a main body with an internal partition and an inner cavity. A motor is fixedly installed within the main body, and a turntable is located within the inner cavity, connected to the motor. The turntable includes a rotating plate, a rubber pad, and a guiding structure. This nitrifying bacteria cultivation chamber for a water filtration system, through its turntable, allows the culture dish to rotate, ensuring uniform temperature distribution during cultivation and protecting the incubator. The guiding structure within the turntable ensures stability and smoothness during rotation. Furthermore, the guide structure is detachable for easy replacement. A detachable observation structure facilitates observation and disassembly for cleaning and other related operations.
[0004] Based on the above, existing mobile nitrifying bacteria cultivation vehicles require the discharge of high-concentration bacterial solutions from the cultivation chamber to the wastewater tank via connecting pipes during operation. However, the biological packing material (such as porous polyurethane or volcanic rock) filled in the cultivation chamber serves as a carrier for the attachment and growth of nitrifying bacteria. During the discharge process, it is easily displaced by the impact of water flow. Due to the lightweight and porous nature of the packing material, the fluid dynamics during discharge cause the packing material to accumulate along with the bacterial solution towards the connecting pipe, especially at the pipe interface, resulting in pipe blockage. This problem not only reduces the efficiency of bacterial solution discharge but may also cause equipment failure due to abnormal local pressure, and may even require frequent shutdowns for cleaning, seriously affecting the continuous operation capability of the cultivation vehicle and the progress of wastewater treatment projects.
