| Abstract | The washing plant of Beitou Waste Incineration Plants used washed method to remove Heavy Metal , Dioxin and Chloride of fly ash. Affter washing, precipitation, stabilization and dehydration, washed stabilization fly ash was sent to the cement plant for "reuse" as a part of alternative soil to Portland cement. In this study, the feasibility of building a washed device was evaluated and ˇ§the most economicˇ¨ process was planned by analyzing the physical properties, chemical composition, the TCLP of heavy metals and dissolved salts of fly ash and reaction ash in Bali Waste Incineration Plants, the current situation of effluent water quality in Bali Landfill Side Leachate Treatment Plant, investigating the existing waste disposal facilities with the site survey, based on washed process in Beitou Waste Incineration Plants. The result of study suggested it is favorable to set the washed device in Bali landfill leaking water plant, in which the existing process of removing heavy metal from wastewater is coagulation and sedimentation, pressurized flotation (DAF) and activated carbon. The effluent discharged to sea after finishing the primary treatment in the wastewater treatment plant. Thus, the chloride problem has be solved. The ˇ§most economicˇ¨ washed process is to adopt the 3-stage washed method (L/Sˇ×30). In the first stage, the effluent from exudation plant was used for washing; and in the second stage, daily discharge water from the pool attached to Bali incineration plant supplemented with tap water or recycled were used to wash again; then in the third stage, using chelating agents removed insoluble chloride. And this should reach the standard of cement plant. |
