摘要： 为指导消防污水的处理回用，选取柴油、汽油2种典型成品油以及硅胶、二氧化硅2种微米级固体粉末配置不同含量的污水发泡，测试油、固含量对发泡性能的影响。结果表明：在0~3%质量分数范围内，柴油主要影响发泡倍数，降幅可达40.15%；汽油主要影响25%析液时间，降幅可达33.05%；直径大于10 µm的固体颗粒对发泡倍数和析液时间均有影响，前者降幅可达25.22%，后者降幅可达18.49%。

Abstract: In order to guide the treatment and reuse of fire sewage, two typical refined oils of diesel and gasoline and two micron solid powders of silica gel and silicon dioxide were selected to mix sewage with different mass fraction, and the influence of oil and solid content on foaming properties is tested. The experimental results show that when the mass fraction is 0~3%, diesel mainly affects the expansion ratio, with a decrease of 40.15%, gasoline mainly affects the 25% drainage time, with a decrease of 33.05%. Solid particles (Φ>10 µm) have an effect on both expansion ratio and 25% drainage time, with the former decreasing by 25.22% and the latter decreasing by 18.49%.

Key words: foam, oil mass fraction, solid mass fraction, drainage time, expansion ratio
