| Summary: | 碩士 === 國立臺北科技大學 === 環境工程與管理研究所 === 97 === Taipei Government presently adjusts the plan for managing Municipal Solid Waste(MSW) to be the new policy, that is, “reducing, resourcing, and multiple treatments ”; besides, Department of Environment Protection also actively sets every plan, which is reducing, classifying , and resource recycling respectively, into action in order to minimize the source of MSW for recycling any kind of useful resources and reuse and transform the environment into a truly recycling material society. The projects can comparatively minimize the annual amount of MSW and reduce the quantities of refuse trement of three major Taipei Refuse Incineration Plants simultaneously and lead to the straight impact to the operation. Therefore, the study of MSW minimization for refuse incineration plant operation on the impact of the issue, as the delay.
In order to investigate the MSW minimization impact on the operation of refuse incineration plants, Taipei City Mu-Zha Refuse Incineration Plant is the main object of the proposal for the purpose of researching the effect and result toward the refuse incineration plant while executing MSW minimization. The application and technology, operation and maintenance, spending and benefit, environment consideration, and administrative manage are evaluated according to the established data, documents as well as the interview with the incineration administrators. The report provides that electrical generation, electrical selling, and earnings of electrical selling are apt to shrink after minimizing the amount of MSW; however, electrical generation and earnings of electrical selling per ton increase before the plane of reducing the MSW. The incinerator, combustion control, and air pollution control are not impact by waste minimization.The lower heating value brought the annual average for 2007 up to 2,125 kcal/kg, which was higher than 2,000-kcal/ kg in the highest design value, exceeding heat load in combustion chamber resulting in corroding pipes of boiler and the broken pipes and the frequently unexpected closure for the operation. Thus, it leads to repair the boiler, and it greatly influenced the operation.It has been over 13 years since the formal operation of the Taipei City Mu-Zha Refuse Incineration Plant in 1995. The major facilities become outdated and the efficiency of the operation gradually declines with the march of time. The efforts of maintain and spending increase as well.
Furthermore, spending of trement per ton obviously increase NT$1,808 after reducing the MSW. The trement spending does not decrease with MSW minimization but rather increase. It leads to negative influence toward the operation spending. What invest does not have direct economical effects; however, the indirect economical effects offset what direct economic effects lack. The energy consuming, water exhausting, emissions quantities of air pollutants, quantities of wastewater discharging, and quantities of ash emission are apparently decrease after waste minimization and offer positive effect toward the environment. The strict waste management is helpful for the assurance toward the incinerator with the safe operation. Thus, the annual assessment presents that it maintains the highly effective operation and makes the contaminated environment control conform to the standard and does not result in negative consequence.
