摘要
依据2011年8月舟山电厂附近海域环境现状调查结果,表层温排水温升4℃、3℃、2℃、1℃包络线影响范围分别为0.092 km2、0.137 km2、0.294 km2、1.251 km2。余氯分布无明显规律性;结合舟山电厂建设前的环境现状资料,分析舟山电厂温排水对附近海域环境造成的影响。结果表明,舟山电厂运行后,溶解氧含量明显降低,重金属汞含量超二类海水水质标准,可能与脱硫海水的排放有关。总的来说,电厂温排水对附近海域水环境和沉积物环境的影响较小。
Based on the environmental status survey results of neighbouring sea area of Zhoushan Power Plant in August, 2011, when the temperature elevation of the surface layer thermal discharge was 4 ℃, 3 ℃, 2 ℃, and 1 ℃, the influence range of envelope curve was 0. 092 km^2, 0. 137 km^2, 0. 294 km^2 and 1. 251 km^2, respectively. The distribution of residual chlorine showed no obvious regularity. Combined with the environmental status data before the construction of the power plant, the analysis of the influence of thermal discharge from Zhoushan Power Plant to the adjacent sea area showed that the content of the dissolved oxygen decreased obviously. The content of heavy metal Hg exceeded the second class of seawater quality standards, probably relative to the discharge of desulfurized seawater. It showed that the thermal discharge water of Zhoushan Power Plant had little influence on water environment and sediment environment of the adjacent sea.
