Embodiment Construction

[0023] The liquid flows upward in the sedimentation tank, and flows out through the rectification section and the inclined plate area. The well-reacted particles settle to the surface of the sloping plate according to the precipitation mechanism and slide down the sloping plate to the lower part of the sloping plate area. In the lower part of the inclined plate area and in the rectification section, the particles will be dragged by the upward water flow, and cannot slide down the rectification area to leave the equipment. Only the particles with larger particle size and density can leave the suspension area through the jacking action of the lower liquid flow, and settle to the bottom of the sedimentation tank for discharge.

[0024] After the mixing and reaction process, the liquid-solid two-phase mixed liquid passes through the water distribution section of the sedimentation tank, flows upward into the equipment, and flows into the space formed by the inclined plate protectio...

Abstract

A flocculating settling apparatus with counter-current contact is composed of a settling pool, slant-plate settling segment, current rectifying plate segment, and speed regulating plates perpendicularly fixed to the current rectifying plates. Its advantages are high load capacity, high clarifying effect, less consumption of chemical, and low cost.

Description

Technical field: [0001] The invention belongs to the technical field of solid-liquid precipitation separation and relates to an improvement of water treatment equipment technology. Background technique: [0002] At present, the main disadvantage of the water treatment and sedimentation equipment used is that the solid particles in the sedimentation tank have more leakage in the sedimentation tank, the turbidity of the effluent from the sedimentation tank cannot be further reduced, and the sedimentation efficiency and sedimentation effect are not ideal. The main reason for the above problems is that the removal mechanism of the sedimentation tank is the shallow pool theory of sedimentation, and its sediment removal ratio mainly depends on the length of the inclined plate equipment in the sedimentation tank and the distance between the inclined plates (sedimentation distance). For particles with certain properties, when the length of the inclined plate and the sedimentation di...
