Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment microbial agent storage and activation dosing device. Background Art

[0002] With the rapid development of industrialization and urbanization, sewage treatment has become a key link in environmental protection and sustainable development. In the sewage treatment process, in order to maintain and enhance the function of the sewage treatment biochemical system, it is necessary to regularly add microbial agents with certain functions into the sewage treatment biochemical system.

[0003] Microbial agents are usually made of a mixture of liquid agents, solid powder and a certain amount of water for dissolution and dilution. They need to be activated on site when used and then added to the sewage pool at intervals according to the sewage treatment process. Since the microbial agents are not poured in at one time, the activated microbial agents need to be stored for a certain period of time. Currently, most of them are placed in barrel containers. When the microbial agents are left standing in the container, components will precipitate, and the lack of insulation will reduce the activity, which seriously affects the use effect of the microbial agents.

[0004] Therefore, the utility model proposes a sewage treatment microbial agent storage and activation dosing device to solve the above problems. Utility Model Content
