[0002] With the continuous development of human society, water consumption and drainage volume have continued to increase, exacerbating water shortages and water pollution, and environmental problems have become increasingly prominent. Since the reform and opening up, the rapid economic development and further acceleration of urbanization have further highlighted the contradiction between urban water supply and demand. In order to solve the contradiction of water shortage, it is necessary to adopt a sustainable water resource utilization model - a conservation model. In addition to promoting water conservation and opening up new water sources, the recycling and utilization of sewage and wastewater is also an important way.

[0003] The sewage discharged by residents in their daily lives is usually discharged directly into the sewage treatment plant through the sewer pipe. During the treatment process of domestic sewage, since it contains a lot of solid waste, these wastes are easily accumulated after being discharged with the wastewater, causing blockage and increasing the workload of the staff. Therefore, a filter box for treating domestic sewage is designed to solve the above problems. Utility Model Content

[0004] In response to the above technical problems, the utility model provides a filter box for treating domestic sewage. A scraping component and a collecting component are arranged in the filter box, thereby greatly reducing the problem of solid waste in the water causing filter clogging during sewage treatment. The waste is basically concentrated in the collection box, so the staff only needs to open the cleaning cover regularly to take it out for cleaning, which is highly practical.
