[0001] The invention relates to the technical field of tap water treatment, in particular to a tap water treatment system. Background Art

[0002] Tap water is water that meets the corresponding standards for people's daily life and production use after being purified and disinfected by a water treatment plant. The water source usually comes from rivers, lakes and groundwater, and the raw water is transported to the water plant through a water pumping station.

[0003] Tap water purification is a process of removing impurities from water through physical and chemical methods. Water plants usually use V-type filter tanks for physical impurity removal. The V-type filter tank uses quartz sand filter media to intercept suspended matter and impurities in the water on the surface of the quartz sand filter media, so that the water quality is further clarified. After long-term use of existing V-type filter tank filtering equipment, the quartz sand filter media accumulates impurities, which will cause the V-type filter tank's clear water pass rate to gradually decrease. The quartz sand is reversely flushed by the backwashing method to clean the quartz sand filter media, so that the quartz sand filter media can be reused to continue the filtering effect of the V-type filter tank.
