摘　　要：以微涡旋水力澄清器水样中颗粒物的Zeta电位为研究对象,用微观视角探讨澄清器的净水机理,实现澄清器净水工艺的改进。静态试验初步选出合适的混凝药剂聚合氯化铝铁(PAFC)和助凝剂聚丙烯酰胺(PAM),动态试验阶段重点就PAFC和PAFC+PAM对原水的处理情况,对澄清器的运行状况进行检验。在一段时间内,单独投加PAFC时,测得翼片隔板反应区某取样口的水样浊度稳定在65.0～66.8NTU,Zeta电位基本稳定在-13.6～-13.7mV;投加PAFC+PAM时,测得翼片隔板反应区同一取样口的水样浊度基本稳定在63.0～65.0NTU,Zeta电位基本稳定在-13.0～-13.2mV,证明了澄清器运行情况基本稳定。The micro-vortex clarifier of high density reticular flocculation was designed based on the research hotspot of high density clarifying technology and in combine with vortex diffusion,sludge suspension layer,wing sheet type inclined plates theory and material balance calculation equation.The PAFC and PAM were selected as flocculants by static experiment.The turbidity of water sample in wing reacting area was 65.0～66.8 NTU and Zeta potential was-13.6～-13.7 mV with adding PAFC.The turbidity of water sample in wing reacting area became 63.0～65.0 NTU and Zeta potential was-13.0～-13.2 mV with adding PAFC＋PAM.
