【 摘 要 】

To process the coal wastewater, the combination of chemical based technology of Advanced Oxidation Process (AOP) of a strong oxidizer using TiO2photocatalyst and biological treatment of moringa seed powder (Moringa oleifera) is used in the composite form. AOP can be used as an alternative treatment of coal wastewater which is quite economical and environmentally friendly. The XRD results of TiO2powder and the synthesis of TiO2- is moringa seed powder in the form of tetragonal crystals. The degradation results of the quality of the coal wastewater using TiO2powder reached a decrease of (TSS, Fe, Mn, Zn, Hg, Cu, Co, Cr, Al and Ni) by an average of 70% and the increase of pH value of 7 at 200 minute stirring time. The decrease of the wastewater quality using the synthesis of TiO2-moringa seed powder by using sunlight and without sunlight is detected negative (-) at 200 minute stirring time.
