摘要
结合现有的中试试验系统,开展了强化混凝工艺的试验研究,结果表明,在该水质期,混凝剂PAC对浊度和CODMn的去除效果较优于混凝剂FeCl3;然而在满足出水浊度和CODMn要求的情况下,每处理单位水体PAC混凝药剂费用远高于FeCl3;使用NaSiO3与FeCl3混合液作为混凝剂时,适当增大混合液中NaSiO3的比例有利于提高常规工艺处理效率。
Combined with the existing pilot test system,experimental study of enhanced coagulation technology was launched.The results showed that coagulant PAC has a better effect to remove turbidity and CODMn than coagulant FeCl3 under the present period of water quality.However,under the situation of meeting the requirements of the water turbidity and CODMn case,each processing unit of water coagulation pharmacy PAC cost is much higher than FeCl3,when using NaSiO3 with FeCl3 as coagulant mixture,appropriately increasing the proportion of mixture NaSiO3 helps to improve the treatment efficiency of conventional technology.
