Description

Integrated coagulation inclined plate sedimentation device

Technical Field

The invention belongs to the technical field of sewage treatment, and particularly relates to an integrated coagulation inclined plate sedimentation device.

Background

The coagulating sedimentation consists of mixed flocculation and sedimentation. The coagulation process is that a flocculating agent is added to fully mix the flocculating agent with the wastewater in a hydraulic or mechanical stirring mode, and flocculating bodies collide with each other to form ideal alum flocs so as to be precipitated and separated in a sedimentation tank. The inclined plate precipitator is often adopted in the existing sedimentation tank to improve the sedimentation efficiency, but the inclined plate precipitator is difficult to clean, the whole treatment line is required to be stopped for cleaning, and the cleaning and maintenance cost is improved. In addition, the success of the dewatering treatment of the sludge depends to a large extent on how the sludge can be effectively flocculated by the flocculating agent. It is now common practice to have the flocculant react homogeneously with the sludge by means of a stirrer, but in the case of the present stirrers, the dispersing effect on the flocculant is not ideal, which greatly affects the final flocculation.
