摘要
通过投加高铁酸盐对微污染原水进行预氧化和强化混凝处理,考察了处理效果,并对药剂投加方式和投加量进行了优化。结果表明,高铁酸盐和硫酸铝复合投加的处理效果优于单独投加高铁酸盐、硫酸铝或聚合氯化铝铁的,可有效去除有机物、浊度和氨氮,在较优药剂组合和投量下,可保证沉后水的CODMn和浊度分别低于3.0 mg/L和0.5 NTU。
The pre-oxidation and enhanced coagulation of micro-polluted raw water were conducted by adding ferrate. The treatment efficiency, chemical dosing method and dosage were investigated. The results indicate that the treatment efficiency of ferrale combined with aluminum sulfate is better than that of single ferrate, aluminum sulfate and polymeric aluminum ferric chloride. The organic matter, turbidity and ammonia nitrogen can be effectively removed. Under the optimum process, CODMn and turbidity of the sedimentation water are less than 3.0 mg/L and 0.5 NTU respectively.
