溶气气浮法(Dissolved Air Flotation,DAF)是一种广泛应用于水处理领域的高效固液分离技术。其核心原理是通过将空气加压溶解于水中,随后在常压环境下释放形成微纳米级气泡,这些气泡与水中悬浮物、油脂或胶体物质结合,形成密度小于水的浮体,最终通过刮渣装置实现污染物分离。
该技术包含三个关键步骤:
根据美国环境保护署技术报告,DAF系统对悬浮物的去除率可达85-95%,特别适用于藻类去除、石油化工废水处理等场景(来源:US EPA Water Technology Fact Sheet)。在饮用水处理领域,中国给水排水设计规范明确将DAF列为应对高藻水体的推荐工艺(来源:CJJ 41-2019《城镇给水厂处理技术规范》)。
