Separate-bed ultra-pulse clarifying device

Abstract

The invention discloses a separate-bed ultra-pulse clarifying device which comprises a pool body, a water allocation component, a pulse generator, a water distribution component, a sludge concentration chamber, an inclined tube component and a clear water collection mechanism, wherein a sludge flocculation adsorption area, a separation area, an inclined tube sedimentation area and a clear water area are arranged in the pool body from bottom to top; the sludge flocculation adsorption area at the bottom of the pool body is divided into at least two separate-bed sludge flocculation adsorption areas; each separate-bed sludge flocculation adsorption area is provided with a water allocation component, a pulse generator, a water distribution component and a sludge discharge component; and the separate beds share the separation area, the inclined tube sedimentation area and the clear water area above. The device disclosed by the invention has the beneficial effects that one separate bed is adjusted to work in variable working condition and other separate beds are in efficient and stable design working condition, and the flexibility and operability of load adjustment are good; the pulse generator of each separate bed realizes Brownian movement thereof to accelerate flocculation and adsorption; and by sharing the separation area and the inclined tube area, the rising speed of each separate bed is greatly reduced at the middle part, and pool return does not happen easily.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, and in particular relates to a water supply purification and clarification device. Background technique [0002] With the process of national industrialization and urbanization, the discharge of industrial and domestic sewage has increased significantly, and the treatment of sewage has become an urgent problem to be solved for sustainable development. The clarifier is a water supply treatment system that uses the mud accumulated in the tank to contact and adsorb the impurity particles in the raw water to achieve a faster separation from the clean water. [0003] For example, China's utility model patent No. 200920147687.6 discloses a pulse clarifier. The interior of the tank is configured as a sludge flocculation adsorption zone, a separation zone, an inclined tube sedimentation zone, and a clean water zone from bottom to top; it mainly uses the pulse water distribution method,...

AI Technical Summary

Problems solved by technology

[0004] At present, there is still a lot of room for improvement in the existing technology, which is mainly reflected in the fact that the existing clarifier equipment belongs to the whole bed structure, that is, the sludge flocculation and adsorption area in each equipment is set in a single and large area, and only equipped with A set of pulse generator, which results in small ascending flow rate, low sludge concentration and poor flocculation effect

In addition, when the hydraulic load or pollution load of the existing clarifier equipment is impacted, it is easy to reverse the tank (turn over the old bottom) and the sludge will float up, deteriorating the water quality
