摘要

以海洋沉积物为研究对象,通过动态模拟实验研究了海洋沉积物中石油类污染物释放的影响因素及各条件下上覆水体中污染物浓度随时间的变化规律。实验结果表明,海洋沉积物中石油类污染物释放强度与沉积物土壤颗粒是否悬起有关,当土壤颗粒大量悬起时污染物释放强度得到显著提高;上覆水体盐度的增加抑制了石油类污染物的释放;海洋沉积物在一定的受污染范围内,随着受污染程度的增加,石油类污染物的释放强度会随之增加;上覆水体中石油类污染物的浓度与反应物的固液比成正相关。
        Taking marine sediment as the research object, this paper studied influencing factors of the release of petroleum pollutants in marine sediments and the variation of concentration of pollutants in overlying water with time under various conditions by dynamic simulation experiments. The experimental results showed that the release intensity of petroleum pollutants in marine sediments is related to whether the sediment particles are suspended. The pollutant release intensity is significantly increased when a large amount of soil particles are suspended. The increase in salinity of the overlying water inhibits the release of petroleum contaminants. When marine sediments are polluted within a certain range, the release intensity of petroleum pollutants will increase with the increase of pollution degree s. Concentration of petroleum pollutants in overlying water is positively correlated with the solid/liquid ratios of the reactants.
