Abstract
PURPOSE: To prevent closing of bed and perform effective capturing by processing the heavy metal waste water containing suspensions by the use of the swollen bed of the humic acid base heavy metal capturing agents which are 1.2 or over in specific gravity, is within the range of 0.15W2.4mm in grain diameter and has grain size widths of more than 300μ.
CONSTITUTION: The humic acid base heavy metal capturing agents which are 1.2 or over in specific gravity, is within the range of 0.15W2.4mm in grain diameter and has grain size widths of more than 300μ are packed in a tower, where the waste water containing heavy metals including floating suspensions is flowed upward at a feed rate of 5W20m/Hr to allow the capturing agents to spread, whereby the mixing of the suspensions in the waste water over the entire part of the capturing layer is prevented although they smoothly pass through said layer and the processing is accomplished while a constant adsorption band is being formed.
