| 摘 要： | 介绍了利用次氯酸钠的强氧化作用来处理含硫水煤气废水。NaClO与水中S^2-等还原性物质的反应为典型的氧化还原反应，随着S^2-的被氧化，其氧化还原电位是变化的。针对这点，本文主要研究NaClO的投加量对S^2-氧化还原电位的影响，并以此来控制实际工程中NaClO的投加量，防止NaClO的过量投加带来对设备的腐蚀和对水煤气质量的影响。

| Abstract: | The method of treatment of water-gas wastewater containing S2- using strong oxidation of sodium hypochlorite is introduced. The reaction of NaCIO and reducing substances like S2- is a typical oxidation-reduction reaction. The reduction-oxidation potential keeps changing during the oxidation of S2-. In this regard, this paper mainly focuses on the effect of NaClO dosage on reduction-oxidation potential of S2- , based on which the dosage of NaClO can be controlled in practical projects to avoid equipment erosion and bad influence on water gas quality due to excessive dosage. |
