Description

Technical Field

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

[0002] A sewage treatment device refers to a device that treats domestic sewage or industrial sewage. Domestic sewage contains a large amount of debris such as mud, sand and gravel. A large amount of solid waste will cause great damage to the environment if it is discharged without treatment. The sewage treatment device can be used to treat impurities or odors in the sewage, so that the sewage can meet the discharge standards.

[0003] Filter components, such as filter plates and activated carbon filter layers, are installed inside the sewage treatment device. The filter plate can filter out impurities in the sewage through its filtering effect to prevent the impurities from being discharged with the water flow. The filter plate can filter impurities through holes of specific sizes inside. However, impurities can easily clog the filter screen during the filtering process, requiring staff to clean it regularly, which is very troublesome to use. To this end, we provide a filter device for sewage discharge to solve the above problems. Utility Model Content
