Low-pulsation inclined plate precipitation device

Abstract

The invention discloses a low-pulse inclined plate sedimentation device which comprises a sedimentation tank, an inclined plate group, a perforated water collecting pipe and a perforated sludge discharge pipe, a clear water area, an inclined pipe area, a water distribution area and a sludge deposition area are sequentially arranged in the sedimentation tank from top to bottom, the perforated water collecting pipe is transversely arranged in the clear water area, the inclined pipe area is fixedly provided with the inclined plate group, one side of the water distribution area is provided with a water inlet, and the other side of the water distribution area is provided with a water outlet; and a perforated sludge discharge pipe is transversely arranged in the sludge deposition area. According to the sewage treatment device, the perforated plate is arranged, so that particles uniformly fall into the next-stage space through the filter holes in the downward sliding process, are subjected to convection collision with new flocculated sludge in the next-stage space, continuously grow under the action of contact flocculation to form large-particle precipitates, and further fall into the sludge accumulation area under the action of gravity to be discharged; sludge is effectively prevented from being accumulated between the inclined plates, and the sedimentation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, and more particularly, to a low-pulsation inclined plate precipitation device. Background technique [0002] The inclined plate sedimentation tank is a high-efficiency combined sedimentation tank designed according to the shallow tank sedimentation theory, also known as the shallow tank sedimentation tank. Or sedimentation is carried out in the inclined pipe, the water flows upward along the inclined plate or inclined pipe, and the separated sludge slides down along the inclined plate (pipe) to the bottom of the pool under the action of gravity, and then is discharged centrally. [0003] However, when the current inclined plate sedimentation tank is used for a long time or the water quality changes, the sedimented sludge continuously slides to the bottom of the inclined plate, which is easy to cause the accumulation of sludge between the inclined plates, thereby reducing the sed...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that sludge accumulation is prone to occur between the inclined plates of the existing inclined plate sedimentation tank, resulting in a decrease in sedimentation efficiency
