摘要
为了及时、有效地应对突发性石油水污染事件,以石油类在水体中的存在形式、进入水厂污染原水中油微粒的赋存状态为切入点,研究了常规混凝沉淀和粉末活性炭吸附技术对石油类的处理效果.试验结果表明:突发性石油泄露时,石油类在水体中主要以漂浮油形式存在;在进厂污染原水中,油微粒主要以黏附态赋存,所占比例在60%以上;水厂常规混凝工艺可处理的石油类最大质量浓度为0.13mg/L;粉末活性炭对石油类的快速吸附时间为10min,在粉末活性炭投加量为30mg/L时,石油类的最大可处理质量浓度为2.1～2.6mg/L.
The existing forms of petroleum and the occurrence states of oil particulates under accidental water pollution by petroleum were analyzed as starting points. The removal effects of coagulation- sedimentation and powdered activated carbon adsorption were studied. The results stated that the floating oil was the main existing form in the water when oil spilt. Adsorbed oils which accounted for above 60% of the total oils deserved more attention under accidental water pollution by petroleum. The maximum mass concentration that could be treated by existing common process was 0. 13 mg/L. The fast adsorption time of powdered activated carbon adsorption to petroleum was about 10 minutes. When adding 30 mg/L powdered activated carbon, the maximum mass concentration that can be treated was 2. 1 - 2. 6 mg/L.
