摘　　要：为了了解舟山绿色石化基地的水质特征,2021年5月对基地2个水体单元,完成了9个站位水质调查,进行时空对比研究,结果显示:(1)在海域环境质量现状调查中,无机氮在全部站位、活性磷酸盐部分站位劣于第四类海水水质标准,其他常规水质参数均符合第一类海水水质标准;(2)绿色石化基地内外水质保持一致,营养盐指标略有改善。(3)工程实施前后,各项水质指标变化不大,除营养盐外,各项指标均符合一类水质标准。无机氮浓度有所下降,活性磷酸盐有所上升,磷酸盐的变化与外部海水的整体变化趋势一致;(4)综合时间、空间的纵横向分析比较,舟山绿色石化基地水质保持稳定,内、外部海水水质保持一致,石化特征污染物均未检出,体现了绿色石化的环保的要求。Principal component analysis and cluster analysis were used to analyze the spatial zoning of water quality and the main water pollution characteristics in Zhoushan green petrochemical base based on a systematic water environment research.Moreover,the spatio-temporal comparative study was carried out.The results showed that the inorganic nitrogen in all stations and some stations of active phosphate were inferior to the fourth class seawater quality standard,and other principal component parameters met the first class seawater quality standard.The water quality inside and outside the base remained the nearly same level,and the nutrient index improved slightly.Before and after the implementation of the project,all water quality indicators had little change.Except for nutrients,all indicators met class I water quality standards.The concentration of inorganic nitrogen in the stations decreased inconspicuously and the active phosphate increased,and the change trend of phosphate was consistent with the overall change trend of external seawater.Based on the vertical and horizontal analysis and comparison of time and space,the water quality of Zhoushan green petrochemical base remained stable,and the water quality of internal and external seawater remained consistent,petrochemical characteristic pollutants were below the detection limit,reflecting the environmental protection requirements of the green petrochemical.
