Description

Technical Field

[0001] The utility model relates to the technical field of water outlet weirs, and in particular to an ultraviolet sterilization water outlet weir for sewage treatment. Background Art

[0002] In the existing sewage treatment methods, multi-stage biodegradation is often used to achieve the purpose of purification. Through the combination of overflow trough and overflow weir plate, sewage is allowed to overflow from the overflow weir plate. First, garbage is physically intercepted and sand and gravel are precipitated, and then biochemical treatment is carried out to facilitate microbial treatment of organic matter and heavy metals in sewage. Finally, it is disinfected by ultraviolet light.

[0003] After searching, it was found that the publication number is CN212356944U, and the name is an ultraviolet sterilization water outlet weir device for sewage treatment. The application points out that the existing ultraviolet sterilization water outlet weir device still has some shortcomings. For example, the existing ultraviolet sterilization water outlet weir device generally uses a filter to perform physical interception, but the surface of the filter is prone to accumulation of impurities after long-term use and is difficult to clean, and the settled sand and gravel inside the water storage tank is also difficult to clean. The cleaning plate is raised by holding the pull rod, and the cleaning brush on the surface cleans the front surface of the filter when the cleaning plate moves. After it is raised, the mud and sand inside the groove can be cleaned. However, in actual use, due to the high frequency of filter clogging, the staff's manual operation frequency is high, which is time-consuming and labor-intensive, and the work efficiency is not high. Further improvements can be made. At the same time, due to the fast water flow rate, in this application, when the water flows quickly through the ultraviolet lamp, the ultraviolet irradiation time is short, the sterilization efficiency is low, resulting in low work efficiency, which can also be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
