Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a vertical anaerobic bacteria sewage sterilization device. Background Art

[0002] The adaptability of sewage treatment bacteria to temperature is one of the key factors affecting their growth and reproduction ability. Generally speaking, bacteria can achieve better growth and reproduction at suitable temperatures, and can also better realize the decomposition and transformation of organic matter, nitrogen, phosphorus and other substances in sewage. On the contrary, if the bacteria in the sewage treatment pool have poor temperature adaptability, it will not only easily lead to slow growth and long cycles, but also significantly reduce the treatment effect. In the sewage treatment process, common bacteria include anaerobic bacteria, aerobic bacteria and heterotrophic bacteria. Among them, anaerobic bacteria have strong adaptability to temperature and are suitable for growth and reproduction under low temperature conditions (15℃-25℃), with better treatment effects. Aerobic bacteria and heterotrophic bacteria are more suitable for growth at higher temperatures (25℃-40℃), which is one of the reasons why most sewage treatment processes use high temperature culture.

[0003] However, the existing anaerobic bacteria sewage sterilization equipment leaves the sewage still during use to reduce the flow rate of the sewage. However, in winter or in the north, the temperature is too low and the bottom of the anaerobic bacteria sewage sterilization equipment cannot be exposed to the sun, which will reduce the anaerobic bacteria's treatment efficiency of sewage and may cause the sewage at the bottom of the equipment to freeze. Therefore, it is necessary to propose a new type of vertical anaerobic bacteria sewage sterilization equipment. Utility Model Content

[0007] Preferably, a worm is installed at the output end of the motor, and two connecting brackets are installed on one side of the surface wall of the worm.

[0008] Preferably, one side of the surface wall of the worm is meshingly connected with a worm wheel, and one side of the surface wall of the worm wheel is installed with a roller.
