Abstract

Performance and effectiveness of single and combined coagulants in the treatment of petroleum and flow station wastewater has been studied. In this study, samples of petroleum and flowsation were treated separated with Barium Chloride, Iron (ii) sulphate, Magnesium Oxide and then with mixtures of different chemicals. Standard methods for examination of water and wastewater was used in the analysis of some important physico-chemical parameters. The results of the analysis of all the parameters in the petroleum and flow station wastewater samples treated with six different types of coagulants shows significant changes and variations in the level of virtually all the parameters in the treated samples when compared with that of the blank.The combined chemical coagulants exhibited a high capacity to reduce the pollutants to recommended effluent limits with the mixture of Magnesium Hydroxide and Iron (ii) Sulphate been the most effective coagulants. The result revealed that average value of all selected parameters showed variation from points A to F. However, these variations are not statistically significant with F (0.068019) being less than Fcritical Keywords : Petroleum, Flow station, Wastewater, Coagulants, ANOVA DOI : 10.7176/CPER/62-04 Publication date: January 31 st 2020

复合混凝剂处理石油和泵站废水

研究了单一混凝剂和复合混凝剂处理石油和泵站废水的性能和效果。在本研究中，用氯化钡、硫酸铁、氧化镁分离石油和流体样品，然后用不同化学物质的混合物进行处理。采用水和废水检验标准方法对一些重要的理化参数进行了分析。对六种不同混凝剂处理后的石油和泵站废水样品中所有参数的分析结果表明，与空白样品相比，处理后样品中几乎所有参数的水平都发生了显著变化和变化。混合化学混凝剂可将污染物降至推荐的排放限值，其中氢氧化镁和硫酸铁的混合物是最有效的混凝剂。结果表明，所有选择参数的平均值从A点到F点都有变化，但这些变化不具有统计学意义，F(0.068019)小于F。关键关键词:石油，流站，废水，混凝剂，方差分析DOI: 10.7176/CPER/62-04
