现有的高浊度水澄清方法是向原水中投加水解聚丙烯酰胺(HPAM)溶液,通过混合、反应、分离等过程而获得清水.由于投加的药剂浓度较大,混合分散较 难,造成局部浓度过高,从而导致不能充分发挥絮凝剂的作用.为此,1988年张有威等老师研究了如图1所示的清水回流新工艺.把药剂投入到回流的清水之中,可极大地降低絮凝剂的工作浓度.由于清水量多,易与原 The existing high turbidity water clarification method is to add a hydrolyzed polyacrylamide (HPAM) solution to the raw water and obtain clear water through the processes of mixing, reaction, and separation. Due to the large concentration of the added medicament, mixing and dispersing are difficult, resulting in The local concentration is too high, resulting in the failure to fully play the role of flocculants. To this end, in 1988 Zhang Youwei and other teachers studied the new process of clean water return shown in Figure 1. Putting the chemicals into the refluxing clean water can greatly reduce the The working concentration of flocculant. Due to the amount of water
