摘要
消防废水一般是指在火灾伴随着化学品燃烧或者燃料燃烧而产生的废水,其组成成分复杂、危害大、影响范围广以及CODCr浓度极高,为确保周边水环境安全,预防排入水体时对周边水生生态系统的影响。本文总结了化工行业消防废水污染特征及处理技术进展,并以某化工厂消防废水为例,采用Fenton氧化法处理废水,以Fe2+/H2O2的投放比例、最佳反应时间、最佳pH等因素为研究对象来获得最适反应条件,为类似消防废水处理提供借鉴。
Fire-fighting waste water generally refers to waste water produced by the combustion of chemicals or fuels during fires. Its composition is complex,harmful, and has a wide range of influence and extremely high CODCrconcentration. Impact on surrounding aquatic ecosystems. In this paper, the pollution characteristics and treatment technology progress of fire-fighting wastewater in chemical industry are summarized, and taking a chemical factory’s fire-fighting wastewater as an example, the Fenton oxidation method is used to treat the wastewater. The optimal reaction conditions are obtained by taking the ratio of Fe2+/H2O2,the optimal reaction time, the optimal p H and other factors as the research objects. Provide reference.
