Abstract
A drainage processing apparatus that processes drainage expelled from a scrubber apparatus is provided. The drainage processing apparatus includes: a magnetic powder adding unit that adds magnetic powders to the drainage; a transfer unit that transfers the drainage; and an adsorbing unit that: is provided in the transfer unit; adsorbs bound matter that is contained in the drainage and contains at least a process-target substance and the magnetic powders; and retains the bound matter in the transfer unit. In one example, the adsorbing unit is able to re-release adsorbed bound matter into the transfer unit. In one example, the adsorbing unit has a permanent magnet provided to be directly insertable into and removable from within the transfer unit, and the permanent magnet adsorbs the bound matter by being inserted into the transfer unit, and re-releases the bound matter into the transfer unit by being removed from within the transfer unit.
