Title:
WASTEWATER DISSOLVED-AIR FLOTATION APPARATUS COMBINED WITH SETTLING TANK HAVING SLOPED PLATES
Document Type and Number:
WIPO Patent Application WO/2020/246707
Kind Code:
A1
Abstract:
The present invention relates to a wastewater dissolved-air flotation apparatus combined with a settling tank having sloped plates. The present invention reduces a transfer pressure load according to the discharge of sludge, when the sludge is discharged through a discharge screw which is a discharge means, so as to enable sludge discharge efficiency to be maximized, has a cleaning means so as to enable components provided therein to be easily cleaned, maintained and managed through cleaning when the inside thereof is required to be cleaned, can control the discharge level of wastewater, which has been treated while sludge settlement and suspended particle flotation are stably performed thereon inside a separation tank to which microbubbles are supplied, selectively blocks the supply of the microbubbles into the separation tank so as to use the separation tank as the settling tank and induces settling in a downward vertical direction or an inclined direction so as to enable settling efficiency to be maximized, and improves the walls of the settling separation tank so as to enable the heat insulation effect of the apparatus to be maximized.
