上海铁路机务段含油废水的处理效果

Effect of Oily Wastewater Treatment in Shanghai Railway Depot

  • 摘要: 目的 针对上海机务段含油废水出现超标排放的情况,观察斜板隔油加气浮处理工艺对含油废水的处理效果,为废水处理的日常维护管理提出合理化建议。

    方法 选择2006-2012年上海机务段含油废水在处理前、后常规性监测4项指标

    化学需氧量(chemical oxygen demand, COD)、石油类、pH及悬浮物(suspended solid, SS) 的结果,分析处理前、后废水监测结果的差别及各监测指标之间的相关性。

    结果 处理前、后4项监测指标结果的差异均有统计学意义。处理前石油类与其他3项指标均为正相关, COD与pH也为正相关。处理后各监测指标中pH和SS呈正相关。

    结论 该处理系统基本符合含油废水的处理需求。

     

    Abstract: Objective To evaluate effectiveness of the oily wastewater treatment process with swash plate grease seal and flotation and provide suggestions for wastewater treatment routine maintenance and management.

    Methods The routine monitoring indicators including chemical oxygen demand (COD), oil, pH, and suspended solid (SS) of the wastewater in Shanghai railway depot before and after the treatment launching were used for comparison and correlation analysis using SPSS software.

    Results All the four indicators were statistically improved after the treatment. Before the treatment, the oil indicator was positively correlated with the other three indicators, and the COD and the pH were also positively correlated. After the treatment, the pH and the SS presented a positive correlation.

    Conclusion The treatment system basically meets the requirement of oily wastewater treatment.
