Abstract:

Pollution and waste are continually generated. The production of waste. however. has increased rapidly in recent years. An efficient and safe means of either neutralizing or disposing of this waste has been increasingly researched. In recent times, the potential of recycling and reusing the waste in construction works has been investigated. The studies have highlighted the benefits of such applications. In line with these studies, the current study investigated the suitability of using Incinerator Bottom Ash Waste (lBA W) as an alternative to conventional aggregates in the construction of road

The adsorption capacity of the solid residues, zeolite P derived from the solid residues was compared to the commercial zeolite Y and fresh Arnot fly ash. The quality of the resulting water was assessed using different analytical methods before the reaction with adsorbents and after the reaction and a comp

<p>Fly ash and AMD samples were characterised by standard analytical methods for selection of the test materials. Active treatment by means of mixing fly ash with AMD in beakers and a large tank at pre-determined ratios have shown that fly ash is capable of neutralising AMD and increasing the pH beyond neutral values, which optimises the removal of heavy metals and ions. The trend was: the more fly ash added the quicker was the reaction time and higher the pH values achieved. Iron was reduced by as much 99 % in beaker scale experiments via Fe(OH)3 precipitation at pH values &gt<br>4.0. A 99 %

Abstract:

Modern societies produce large quantities of municipal solid waste (MSW), which is commonly disposed of by incineration. This has several advantages: it reduces the waste’s volume and sterilizes it while also enabling energy recovery. However, MSW incineration has some notable disadvantages, the most widely debated of which is probably the production and release of persistent organic pollutants (POP) such as polychlorinated dibenzofurans (PCDF), dibenzo-p-dioxins (PCDD), biphenyls (PCB) and naphthalenes (PCN). Of the 210 PCDF and PCDD congeners, 17 are toxic, with hormone-disrupting and carcin

碩士<br>弘光科技大學<br>環境工程研究所<br>102<br>There are approximate 8.40 million tones/year municipal solid waste treated by incinerator in Taiwan, and the amount of incineration fly ash is 6.70~7.15 million tones/year. Because the fly ash usually contains various hazardous species such as heavy metals and dioxin, currently the major treatment method of the fly ash by each incineration plant is solidification/stabilization and then landfill. With the decreasing landfill space and the possible risk of hazardous species released by leaching, how to treat and reuse the fly ash effectively is a critical issue

碩士<br>國立中興大學<br>環境工程學系<br>93<br>Abstract The quantities and varieties of solid wastes have increased rapidly, due to the growth in the industry and commerce. The incineration has become the major process to treat municipal solid waste due to the high volume reduction and energy recovery. About 20 municipal waste incinerators operate in Taiwan, and produce a large amount of the bottom ash and fly ash. Hazardous fly ash was generated from the incineration process due to the high proportion of heavy metal existing in input waste. Solidification of fly ash and subsequent landfill disposal has been

博士<br>國立臺北科技大學<br>工程科技研究所<br>101<br>The refuse disposal strategy of Taiwan has adoped incineration as the primary method of treatment with landfills as supplement. Fly ash discharged from municipal solid waste incinerators (MSWI) was classified as hazardous waste because the leashing of heavy metals (especially Pb) and the content of PCDDS/FS are usually over the regulation limits, so it was majorly treated by Solidifition/Stabilization method, after that sent to the landfills for final disposal. Such way will caused the serious loading of limited landfills capacity and also affected the imple

碩士<br>弘光科技大學<br>職業安全與防災研究所<br>98<br>Discharged wastes from municipal solid waste incinerators include fly ash and bottom ash. Ashes that contain heavy metals (Pb, Cd, Cr) are carcinogenic and will cause health problems. As fly ash is highly hazardous, it should be solidified before landfill. There is possible metal exposure among treatment workers. However, there is limited information existed on the occupational hazards in fly ash treatment plants(FATP). The objective of this study was to evaluate metal exposure in fly ash treatment plants through biological and environmental monitoring. 4

In this study, a nitrogen atmosphere thermal plasma process was used for the recovery of heavy metals from incineration bottom ash. And the influences of basicity adjusting, extra salts and carbon addition, for the metal recovery during thermal plasma treatment were discussed. The experimental results showed that the thermal plasma process could recover about 14.53% of Fe from the raw incineration bottom ash. And a higher Fe recovery of 1

Many studies have proved that heavy metals in bottom ash and fly ash are toxic and can cause health effect in human body. The study aims to compare air heavy metal concentrations in bottom ash and fly ash plants of municipal waste incinerator. Furthermore, the study also want to evaluate the heavy metal concentrations in particles with different partic

To optimize the operation conditions in this study, pH control, sorbent additive and mixing time were examed. Results show that under high pH condition, pH = 12, better removal efficiency of COD and color in landfill leachate by coal fly ash addition is achieved. The pH were adjusted by lime and NaOH.
