流域溢油污染中常见吸油材料吸附效果研究

静态条件下,比较探究了不同温度条件5种常见吸油材料(无纺布、吸油毡、海绵、麻袋、活性炭)对油的质量浓度约为140 mg/L的各石油类污染物的吸附效果。结果表明,各常见吸油材料都能达到瞬时吸附石油类污染物的效果;污水温度对各种吸油材料的吸附效果有较大的影响,温度、石油污染物种类的不同影响效果不同;其中,无纺布的吸油能力最好,吸油量可达254.7 mg/g。在实际流域溢油污染应急过程中,可根据其污染石油的含量,以及污染水源的性质合理选择吸油材料,更大效率的提高应急处置能力。

Study on Adsorption Effect of Common Oil Absorbing Materials in Watershed Oil Spill Pollution

Under static conditions, the adsorption effects of five common oil-absorbing materials (non-woven fabric, oil-absorbing felt, sponge, sack, activated carbon) on various petroleum pollutants with oil content of about 140 mg/L were investigated. The results showed that all common oil-absorbing materials could achieve the effect of instantaneous adsorption of petroleum-like pollutants;The sewage temperature had a great influence on the adsorption effect of various oil-absorbing materials, and the different effects of temperature and petroleum pollutant types were different;Among them, the non-woven fabric had the best oil absorption capacity, and the oil absorption ratio could reach 254.7 mg/g. In the emergency process of oil spill pollution in the actual basin, the oil absorbing material could be reasonably selected according to the concentration of the polluted oil and the nature of the polluted water source, and the emergency response capability could be improved more efficiently.
