碱式硫酸铁强化混凝处理微污染原水实验研究

Experimental Research on Enhanced Coagulation to Micro-polluted Raw Water Treatment by [Fe(OH)SO4]n

采用硫酸铁、三氯化铁、聚合氯化铝铁、碱式硫酸铁等混凝剂对微污染原水进行强化混凝处理实验,以有机物去除率、脱色率和出水浊度为评价指标,实验结果表明:新型碱式硫酸铁更适合于处理微污染原水水质,而且该混凝剂具有较好的二次絮凝特性。

Experiments of enhanced coagulation treatment with several coagulants, such as Al2 （SO1）, FeCl3, PAFC and [Fe（OH）SO4]n, to micro-polluted raw water is conducted in this paper. The removal rate of organic matter, deeolorization rate and turbidity of finished water are selected as the water quality evaluation indexes. The results indicate that [Fe（OH）SO4]n, is the fittest coagulant to the raw water, furthermore, it has good secondary flocculatiori property.
