Description

Technical Field

[0001] The invention relates to the technical field of water treatment equipment, in particular to a high-speed sedimentation device for water treatment. Background Art

[0002] In water treatment, sedimentation is the primary process for removing suspended solids. The design and development of sedimentation tanks focuses on increasing the sedimentation area and modifying the flow pattern, aiming to improve the tank's settling efficiency. Currently, there are two methods for improving sedimentation efficiency: shortening the particle settling distance and increasing the tank area, as exemplified by inclined tube sedimentation. The other method is to increase the sinking velocity of alum floc particles, achieved through the use of high-efficiency flocculants and optimized flocculation processes.

[0003] The existing technology has the following defects or problems: The publication number of the existing technology is:

[0004] Among the existing public documents, patent announcement number CN209226708U discloses an integrated device for high-speed sedimentation of micro-sand for removing high-concentration suspended solids, which relates to the field of water treatment technology and includes a coagulation tank, a flocculation tank and a sedimentation tank. A water inlet pipe is provided at the bottom of the coagulation tank, and a first vertical mixer and a second vertical mixer are installed inside the coagulation tank and the flocculation tank, respectively.

A guide tube with upper and lower openings is provided in the middle of the flocculation tank, and the coagulation tank is connected to the guide tube through a guide tube provided at the top; the sedimentation tank adopts a large-flow double-circulation system to recycle micro-sand and separate sludge.
