碩士 === 國立中山大學 === 海洋環境學系 === 83 === Seawater flocculation is achieved mainly by the formation of great amounts of magnesium hydroxide with magnesium ions presenting in great amounts in seawater controlled under high pH values.The purpose of this study is to investigate the treatment efficiencies of raw leachate and the effluent of leachate from anaerobic filter and the rotating biological contacter(RBC) treatments by seawater flocculation.According to the experimental results,the treatment efficiencies of raw leachate was limited. For the leachate after biological and seawater flocculation treatments,the results showed that the efficiencies were still limited.However,the removal efficiencies of pollutant are proportional to the production of magnesium hydroxide produced in the process.It was concluded that neither seawater flocculation nor combination of biofilm biological treatment and seawater flocculation showed high removal efficiencies of contaminants from leachate even though seawater flocculation were likely to be more economical used to treatment leachate generated from coastal zone landfill sites. However,it is required to study deeply.
