Description

U-shaped pipe self-adjusting liquid level sewage precipitation mechanism

Technical Field

The utility model belongs to the municipal works field, concretely relates to U-shaped pipe self-interacting liquid level sewage deposits mechanism.

Background

One of the important structures in the solid-liquid separation process of sewage treatment of the sedimentation mechanism realizes the purification of water by utilizing the principle that suspended impurity particles in water flow can be separated from the water flow when the downward sedimentation speed is greater than the upward flowing speed of the water flow or the downward sedimentation time is less than the time of the water flow flowing out of the sedimentation tank.

The existing sewage sedimentation tank is generally large in depth, and easily causes the problems of too much or too little sludge, no discharge and recovery of the too much sludge, and the like. Meanwhile, when the sludge discharge frequency is high, the water content of the discharged sludge is high, and subsequent sludge treatment is not utilized, so that the sludge in a common sedimentation tank can be discharged when more sludge is deposited. However, with the increase of the thickness of the sediment, the accumulated sediment can be disturbed by local turbulence generated when the clear water at the upper layer is discharged, so that flocs and pollutants in the sediment can float again and can be discharged along with the discharged water, the concentration of suspended matters and pollutants in the precipitated water are increased, and the influence on the precipitation effect is reduced. Therefore, if the position of the water outlet is increased, the hydraulic retention time is prolonged when the thickness of the bottom mud is smaller after the mud is discharged, and the sedimentation efficiency is reduced. Therefore, a settling mechanism capable of adjusting the water outlet level according to the thickness of the sludge blanket and reducing the disturbance to the sludge blanket is needed.
