摘　　要：2015年3月至2016年2月对湛江钢铁自备电厂海水脱硫工艺排水口附近海域的pH值和重金属浓度进行了连续监测和调查,分析了排水对受纳水体pH和重金属浓度的影响范围和影响程度,探讨了pH与重金属浓度的耦合关系。结果表明pH和重金属浓度受电厂排水影响的范围较小,分别为1000 m和500 m;对两者进行Pearson相关分析,结果为海水中溶解态的Cu、Zn、总Cr、Ni、Cd和Pb的浓度与pH值呈负相关。The pH and concentration of heavy metals of surrounding sea area that influenced by discharge from flue gas desulfurization system in Zhanjiang power plant were investigated from March 2015 to February 2016. The range and extent of effects of discharge and the relationship between pH and heavy metals were analyzed. The results showed that the discharge of power plant affected pH and concentration of heavy metals in small range,1000 m and 500 m respectively.The Pearson correlations analysis had led to a conclusion that the concentration of heavy metals was negative correlative to the pH.
