Building water supply and drainage system and method

Abstract

The invention discloses a building water supply and drainage system and method, and belongs to the technical field of building water supply and drainage. A building water supply and drainage system comprises a filter box, a water inlet and a water outlet are formed in the top and the bottom of the filter box respectively, a discharging cavity and a filter cavity are formed in the filter box and communicated with each other, two supports are fixedly arranged on the inner wall of the filter cavity, and a filter screen is arranged between the two supports. A moving plate is arranged between the top of the filter screen and the top wall of the filter cavity; according to the water supply and drainage system, impurities on the filter screen can be automatically cleaned while water is drained, the labor amount of workers is reduced, reliable, stable and continuous work of the water supply and drainage system is guaranteed, meanwhile, sewage in the impurities is removed, the discharging and recycling amount of the sewage is guaranteed, and peculiar smells emitted when the impurities are cleaned are reduced; therefore, the operation difficulty of workers is reduced.

Description
