REMOVAL EQUIPMENT OF SLUDGE USING BUBBLE FLOTATION

摘要

PURPOSE: A removal equipment of sludge is provided to remove floated sludge by bubble being generated by aeration in wastewater treatment. The equipment is characterized in that an oxygen supplier (30) makes wastewater and air into jet flow for dissolution of much oxygen, and several wave-shaped bubble separators (11) separate wastewater and bubble produced by aeration. The bubble contains much suspended solid, so sludge is removed by separation of bubble. Separated bubble is flowed into a bubble removal equipment through a bubble-discharge pipe (4). And, separated wastewater is discharged out through a ceramic-ball layer (6) containing zeolite. CONSTITUTION: The shown equipment is characterized by comprising following parts: a jet nozzle (31), equipped with the oxygen supplier (30), to make jet flow; the ceramic ball layer (6) containing zeolite; several wave-shaped bubble separators (11) equipped with above the ceramic-ball layer (6); the bubble-discharge pipe (4) for discharge of bubble containing suspended sludge; a conveyor belt (21) for transferring separated bubble; and a plate (22) for bubble collection, equipped with the conveyor belt (21).
