本文研究了羊胡子草纤维在波罗的海经常发生的条件下水面柴油溢油的去除效果。在实验室尺度实验中检测了低温、盐度和细菌添加剂的影响,在中等尺度实验中填充600 L波罗的海海水,检测了柴油和迅速去除柴油对微生物、浮游植物和贻贝的影响。结果表明在低温条件下羊胡子草对水面柴油具有极佳的吸收力。实验室研究中接种柴油富集微生物显著提高了对柴油的降解作用。在中等尺度实验中,向水池中添加柴油(0.66mg/L,0.533L/m~2)导致微生物密度较其它水池升高,包括接种水池,这表明波罗的海含有碳氢化合物降解自然菌群。在中等尺度的实验中羊胡子草对柴油的去除显著提高了贻贝的存活:在柴油水池和添加羊胡子草的柴油水池中贻贝的死亡率分别是100%和0%。但是存活的贻贝具有一系列病理改变,如炎症反应、退化和细胞死亡。甚至当羊胡子草结合的原油被留在水中,减毒作用仍然显著。本结果说明原油渗漏后迅速的行动对于控制危害非常重要。
In this paper, the removal of oil from surface water of Beauvenoleae grass fiber under the conditions of the Baltic Sea often occurs. The effects of low temperature, salinity and bacterial additives were examined in laboratory-scale experiments. Six hundred L of Baltic Sea water was filled in a medium-scale experiment to examine the effects of diesel and rapidly removing diesel on microbes, phytoplankton and mussels. The results showed that S. glauca had excellent absorbability on water diesel at low temperature. Inoculation of diesel-enriched microorganisms in laboratory studies significantly increased the degradation of diesel fuel. In medium-scale experiments, the addition of diesel (0.66 mg / L, 0.533 L / m ~ 2) to the pond resulted in an increase in microbial density over the other ponds, including inoculation of the ponds, indicating that the Baltic contains hydrocarbons to degrade natural flora. The removal of diesel by S. glauca significantly increased the survival of mussels in medium-scale experiments: the mortality of mussels was 100% and 0%, respectively, in the diesel pools and in the diesel ponds to which S. gramineus was added. However, the surviving mussels have a range of pathological changes, such as inflammatory response, degeneration and cell death. Even when the combination of Cotton Grass is left in the water, the attenuating effect is still significant. This result shows that prompt action after crude oil leakage is very important for controlling hazards.
