| 摘 要： | 对焦化废水采用预氧化(Fenton)-混凝沉淀法进行处理,主要研究了以氯化铁、聚丙烯酰胺(PAM)为混凝剂的混凝沉淀法和Fenton氧化-混凝法的最佳工艺条件。结果表明:Fenton-混凝沉淀法处理焦化废水时,色度、COD、NH3-N去除率分别是84.3%、92.9%、96.2%,均达到国家标准。采用Fenton-混凝沉淀法时处理焦化废水的效率高于单独采用化学混凝法时的处理效率。 |

| Abstract: | An integrated process including Fenton-oxidation, coagulation and sedimentation at bench scale was utilized to treat coking wastewater in order to investigate the best suitable treatment conditions of coagulation-sedimentation process and Fenton-oxidation process with ferric chloride and PAM as coagulants. Results showed that the maximum removal efficiency of COD, color and NH3-N for the integrated process was 92.9%, 84.3% and 96.2% respectively, which can meet national discharge standards. The performance of the integrated process is much better than that of the coagulation-sedimentation process. |
