Movable regulating weir plate and horizontal-flow type automatic flushing sewage purification device

Abstract

A horizontal-flow type automatic flushing sewage purification structure comprises a shell body (14); the shell body (14) is provided with a folded plate reaction area (1), a precipitation area (2) anda purification area (4). The structure is characterized in that the precipitation area (2) is provided with a slanted plate (6), the lower part, directly facing the slanted plate (6), of the shell body (14) is provided with a sludge discharge hopper (13); one side wall plate, close to the purification area (4), of the precipitation area (2) is provided with a weir plate (9) for adjusting the water level of the purification area, water precipitated through the precipitation area (2) goes over the weir plate (9) and enters the purification area (4), and the upper part of the purification area (4) is provided with a high-water-level area (3); the lower part of the purification area (4) is provided with a filter layer (7), and the lower part of the filter layer (7) is provided with a filter cap (8); a part, at the lower part of the filter cap (8), of the shell body (14) is connected with a water discharging pipe (11); and a backwashing water discharging pipe (10) passes through the filterlayer (7) and the purification area (4) and then extends into the high-water-level area (3). The structure has the advantages of simple structure, good backwashing effect, automatic operation and lowcost.

Description

technical field [0001] The invention relates to water treatment equipment, especially sewage treatment equipment, in particular to a movable adjustable weir plate with adjustable backwash water volume and advection automatic flushing sewage purification equipment. Background technique [0002] At present, when the general sewage purification equipment performs backwashing, external power is required to provide pressure water for backwashing. This not only makes the equipment structure complex, increases investment, but also increases the movement cost and control difficulty, so it is necessary to improve it. At the same time, after the fully automatic flushing sewage filtration treatment device has been running for a period of time, due to the increase in the pressure of the intercepted sewage in the purification area, the water level in the purification area rises at this time. When the water level rises to a certain height and exceeds the backwash nozzle, a negative pressur...
