摘　　要：进行了某4×300 MW燃煤锅炉的海水烟气脱硫(海水FGD)系统投运前后的海域监测。研究结果显示,海水曝气工艺可以较好地使脱硫后的海水水质得到恢复,除Hg必须引起严重关注外,排海海水的其他水质指标变化很小,附近海域所受影响甚微。The monitoring results of seawater samples from seawater flue gas desulfurization （FGD） system and surrounding sea area before and after running of seawater FGD system of a 4 × 300 MW coal-fired units in a coal-fired power plant have been presented. The results show that the aeration, mixing and dilution systems have obvious good function on sea water quality＇ s resuming. Most of the water quality indexes remain unchanged and the discharge water has little effect on surrounding sea area except Hg to which more attention is needed.
