TECHNICAL FIELD

[0002] Raw water treatment refers to the process of treating raw water (such as river water, lake water, groundwater, etc.) or tap water and other raw water without any treatment, to remove impurities and pollutants in water, improve water quality, and meet specific use standards. Raw water may contain suspended solids, colloids, organic matter, microorganisms, heavy metals and other impurities and pollutants. These impurities and pollutants not only affect the taste and appearance of water, but also may harm human health. Therefore, treating raw water to remove these impurities and pollutants is an important measure to ensure water quality safety and meet people's demand for water for living and production. Raw water pretreatment is an important step in raw water treatment. During raw water pretreatment, sand filters are often used to filter raw water, thereby reducing the content of silt and suspended particles in raw water and in turn reducing the turbidity of raw water. In the existing patent application No. CN202122027699.9, a vertical sand filter is proposed. Although this sand filter can remove particles filtered from raw water in the filter by washing the filter in forward and reverse directions, the cleaning effect of the filter by flushing in the sand filter is poor, and the particles filtered from raw water in the filter are difficult to be fully and effectively cleaned. Too many particle impurities in the filter will reduce the speed of raw water passing through the sand filter in the subsequent raw water pretreatment process, thereby reducing the efficiency of raw water pretreatment. Therefore, improvement is needed. SUMMARY
