Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device for cities. Background Art

[0002] The existing Chinese patent announcement number is CN215102027U, and the name is a patent for a sewage treatment device for cities. The background technology of the patent clearly records that "urban sewage contains a lot of impurities. When treating it, filtration is usually used as the first treatment method. The existing filtration usually uses a filter as the main filter element, which can isolate a lot of large impurities; and the pH value in sewage is usually high, which will have a certain corrosion effect on the filter. In addition, the impact of the water flow itself greatly reduces the use of the filter itself." The patented technical means are solved, but in this technology, the impurities in the filter box cannot be automatically processed. When there are too many impurities inside, in order to avoid clogging, the device needs to be manually lifted and the impurities on the device need to be cleaned, which is more troublesome to operate.
