Coagulating Sedimentation(混凝沉淀)是水处理和废水处理中的关键工艺,结合了“混凝”(coagulation)和“沉淀”(sedimentation)两个步骤,用于去除水中的悬浮颗粒、胶体物质和其他污染物。以下是其详细解释:
混凝(Coagulation)
通过向水中投加混凝剂(如硫酸铝、氯化铁等),中和悬浮颗粒表面的电荷,使微小颗粒脱稳并聚集成较大的絮体(floc)。这一过程破坏胶体稳定性,促进颗粒结合。例如,美国环境保护署(EPA)指出,混凝能有效去除浊度、病原体和有机物[^]。
沉淀(Sedimentation)
混凝后的水进入沉淀池,在重力作用下,絮体逐渐下沉至池底形成污泥,清水则从上层排出。沉淀效率受水流速度、池体设计及絮体密度影响。据《环境工程:水处理原理》(Water Treatment Principles)描述,优化沉淀过程可提升水质达标率[^]。
应用领域
该技术广泛应用于饮用水净化(如自来水厂)、工业废水处理(如去除重金属)和城市污水处理。世界卫生组织(WHO)强调,混凝沉淀是保障饮用水安全的核心步骤之一[^]。
