黄土-微生物系统处理含油废水的静态模拟试验研究

Static simulation experimental research on the treatment of oily wastewater by natural loess-microorganism system

摘要: 通过室内静态模拟实验,对黄土-微生物系统去除含油废水中石油类污染物的效果进行研究,分析了营养物质、温度、氧化剂及pH值等影响因素,并通过正交试验确定了系统的最佳生态条件。结果表明:黄土-微生物系统处理含油废水的最佳生态条件为:营养物质(C∶N∶P)为500∶6∶1,温度为35℃,H2O2的累积投加量为12mg/L,pH值为7。

Abstract: The removal effect of loess-microorganism system on oil pollution treatment was studied by static simulation laboratory experiments in this paper.The influencing factors such as nutrient substance,temperature,oxidizer and pH were analyzed.The optimal ecological condition was determined through orthogonal experiment.The results show that the best ecological condition of loess-microorganism system is as follow: nutrient proportion(C∶N∶P) is 500∶6∶1,temperature is 35℃,the accumulation dosage of H2O...
