Abstract

An object is to provide an industrially practical treatment method for sea water more friendly to the environment. Sea water is treated at a first step at which a sulfur-absorbing solution (solution to be treated 70) produced by sea water desulfurization is mixed with sea water 50 in a sea water mixing apparatus 20, and its pH is adjusted to higher than 5.5 and lower than 6.5, and at a second step at which aeration is provided in an aeration apparatus 10 to the liquid adjusted at the first step, and its pH is further raised. At the second step, an air supplying unit 11 provides aeration to the sulfur-absorbing solution produced by sea water desulfurization under conditions of a nozzle flow rate and a total aeration flow rate that fulfill the following equations (I), (II), and (III): y >= 0.526+0.0114x (I); 5 <= x <= 35 (II); y <= 1.32 (III) (in the equations (I), (II), and (III), y represents the total aeration flow rate, and x represents the nozzle flow rate).
