Abstract

The present invention is a seawater desulfurization apparatus and an operating method therefor, the seawater desulfurization apparatus being provided with: an absorption column (1) including a dust-removing spray nozzle (8) for absorbing and removing soot and a heavy metal from exhaust gas, a desulfurization spray nozzle (9) provided above the nozzle (8) for absorbing and removing SOx from the exhaust gas using new seawater, and a collector (10) provided between the two nozzles (8, 9) and configured to collect the seawater sprayed from the nozzle (9); and an effluent treatment apparatus (24) configured to extract and store a portion of the seawater in a circulation tank (5) located in the lower part of the absorption column. An index correlated with Cl−concentration of the seawater in the tank (5) that is supplied to the nozzle (8) is constantly or intermittently monitored, and the amount of the seawater in the circulation tank (5) extracted to effluent treatment equipment (24) and th
