Horizontal quicksand filter pool and water treatment process

摘要

The present application discloses a horizontal quicksand filter pool and a water treatment process. The horizontal quick-sand filter pool comprises a pool body (1), a raw water inlet assembly, a sand filter bed (4), a filtered water outlet assembly, an aeration assembly and a backwashing assembly. A water distribution device (3) for feeding into the filtration bed (4), the water inlet pipe (2) is connected to the water distribution device (3), and the water distribution device (3) is provided in the sand filtration bed (4). A plurality of outlet holes are uniformly distributed on the elevation of the water distribution device, and the filtered water outlet assembly has a water collector (5) and a water outlet pipe (7), and the sand filtration of the water collector (5). There is an inlet hole on the side adjacent to the floor (4), the outlet pipe (7) is connected to the water collector (5), and the backwashing assembly connects the backwash pipe (8) and the waste discharge pipe (9). A backwash pipe (8) is connected to a drain pipe (7), and a waste discharge pipe (9) is connected to the water distribution device (3). The filtration area of the horizontal quick-sand filter pool is large, thorough cleaning of sand particles, water saving and energy saving, and the application expansion is diversified, it is not only applied as a filtration device, but also biological contact oxidation and It can be an aerobic / anaerobic biological filtration pool that has the function of shutting off the suspended solids filtration bed.
