| Abstract: | In this work, the conventional treatment technologies for wastewater were compared to optimized the integrated technology aiming to reuse the effluents. It is found that 95% turbidity can be removed by uhrafihration, but little function for organic pollution and heavy metals. Coagulation-sedimentation-filtration is a conventional process, but quite effective in removing turbidity, heavy metals, organic pollutants and 50% -80% of total P. For ozonation-biological activated carbon treatment process, the turbidity and organic pollutants can be removed effectively, with a CODe, removal of 60%-70% and NH3-N removal of 70% -90%, but little effect for heavy metals and bacteria removals. It is justified that only the integrated technologies can effectively remove the wastes from wastewater to reach the standard of reuse water. |
