摘要
泡沫去污技术是对内部结构复杂的空腔结构进行去污的有效技术之一。为提高去污泡沫稳定性,减少二次废液有机物含量,进一步提升去污效率,借助泡沫扫描分析仪对纳米SiO_(2)与烷基糖苷(APG)体系生成泡沫的稳定性进行了研究。结果表明:在一定的浓度范围内两者对泡沫稳定性具有一定的协同作用。在APG质量浓度为10 g·L^(-1)的情况下,推荐纳米SiO_(2)的添加量为3%~4%(质量分数)为宜。
Foam decontamination technology is one of the effective techniques for decontamination of the facility with complex cavity structures. In order to improve the stability of decontamination foam, reduce the organic content of secondary waste liquid and further improve the decontamination efficiency, the effect of nanosilica on the stability of decontamination foam was studied by the experiment apparatus named Foamscan. The results showed that the system of nanosilica and APG had a certain synergistic effect on foam stability within a certain concentration range.When the mass concentration of APG was 10 g·L^(-1), it was recommended that the nanosilica mass fraction was 3%~4%.
