摘要

Soya bean oil mill wastewater (SOMW) is a liquid waste obtained from the soya bean oil industry with several environmental problems due to its high amount of toxic pollutants. This research work is aimed at assessing the feasibility and suitability of using a zeolite-based method for the treatment of soya bean oil mill wastewater for irrigation purposes. In this study, successive columns containing different types of solid-state materials were used to investigate the treatment efficiency of SOMW using physicochemical parameters; pH was determined using a pH meter, Turbidity determined using Turbidity meter. The concentration of Na~(+), Ca~(2+), Mg~(2+), K~(+) were determined using Flame photometer and the concentration of NO_(3)~(-), SO_(4)~(2-), PO_(4)~(3-) were determined using Oxygen Analyzer. Zeolite was characterized using Advanced Powdered X-ray diffractometer, energy dispersive spectrometer and Fourier Transformed Infrared and the fine sand characterized using an integrated X-ray Analyzer. The treatment columns were packed with fine sand, zeolite and zeolite/fine sand composite. The treatment decreased the concentrations of Na~(+), Ca~(2+), Mg~(2+), K~(+), NO_(3)~(-), SO_(4)~(2-), PO_(4)~(3-) and pH by mean percentages of 80.5, 29.6, 81.0, 2.1, 66.5, 41.4, 47.4 and 42.3%, respectively. The turbidity of the soya bean oil mill wastewater decreased by 72.5%. Most contaminants were removed in the soya bean oil wastewater in the zeolite/sand composite column. This decrease in the concentration of the pollutants could be attributed to the high sorption and ion exchange capacity of the solid-state materials used. This simple zeolite-based method is promising technology for the treatment of industrial wastewaters from oil processing industries for irrigational purposes.
