WATER QUALITY-IMPROVING APPARATUS FOR SEAWATER DESULFURIZATION WASTE WATER, AND SEAWATER FLUE GAS DESULFURIZATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a water quality-improving apparatus for seawater desulfurization waste water, which can conduct excellent liquid-liquid mixing without using e.g., a stirrer.SOLUTION: This invention relates to a water quality-improving apparatus provided with an oxidation/aeration section 23 for performing water quality-restoring treatment, using diluting seawater 14b and air 71a, on acidic seawater desulfurization waste water 21 that is generated by seawater desulfurization of sulfur oxides in exhaust gas 12 with seawater 14 using a seawater desulfurization device 15. The water quality-improving apparatus is provided with an inlet-side diluting section 22, which: is provided on an upstream end of the oxidation/aeration section 23, supplies diluting seawater 14b, and mixes with the seawater desulfurization waste water 21; and has at least one vortex-generating resistor 31 that is erected on a bottom surface 22a of the inlet-side diluting section 22.SELECTED DRAWING: Figure 1
