Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and more specifically, to a biological community cultivation device for wastewater treatment. Background Technology

[0002] Organic wastewater contains highly toxic and stable pollutants, making it difficult to treat using conventional physical, chemical, and biological methods. Under current technological and process conditions, ensuring project reuse, water conservation, and compliance with discharge standards presents new requirements and challenges for key technological breakthroughs in the industry. Currently, existing processes generally do not effectively treat COD, heavy metals, and ammonia nitrogen in this type of wastewater simultaneously. Biological treatment is the most crucial part of wastewater treatment, with microbial cultivation being particularly important. Generally, microbial cultivation in wastewater biological treatment involves adding nutrients and aerating the wastewater in a biological treatment tank.

[0003] Currently, some processes that use microbial culture for wastewater treatment require aeration of the microbial community in the culture medium. However, the aeration structure of traditional culture devices is usually located at the bottom, resulting in insufficient contact between the microbial community and oxygen in the culture medium, as well as uneven stirring, which affects the growth of the liquid microbial strains.

[0012] In one specific implementation, the eccentric turntable includes a disc and an eccentric shaft. The disc is fixedly connected to the transmission rod, the eccentric shaft is fixedly connected to the disc, and the rectangular frame is slidably sleeved on the eccentric shaft.

[0013] In the above implementation process, by setting up a disk and an eccentric shaft, the transmission rod drives the disk to rotate, the disk drives the eccentric shaft to move, and the eccentric shaft drives the rectangular frame and the sliding rod to slide up and down.

[0019] In one specific implementation, the top of the incubator is provided with a support rod and a support ring is fixedly connected thereto, and the transmission rod rotates through the support ring.

[0020] In the above implementation process, a support rod and a support ring are set to support the stable rotation of the transmission rod.
