Description
Summary:碩士 === 國立中山大學 === 環境工程研究所 === 106 === In the industrial development of Taiwan, the disposal of waste sludge has become a necessary issue under the demand of many types of industrial oils, and studies have shown that sludge contains high calorific value to recover thermal energy. Most of the unrecovered sludge in China still directly enters the landfill. If it is slightly inappropriate in the process, it will cause serious pollution of soil and groundwater. At present, the landfill is a low-cost and simple method, but its capacity is gradually saturated, and there is also a risk of pollutants being dissolved. Nowadays, environmental awareness is increasing. In order to reduce the cost of pollution and use after fuel combustion, the goal of recycling and recycling of waste is achieved. In this study, the waste wood chips produced from the raw wood processing were used as the substrate, and the sludge provided by the legal sludge recovery and treatment site was uniformly mixed and then pressed into a solid waste-derived fuel-RDF-5. The advantages are uniform heating value, volume reduction, easy storage and transportation, etc., and the current multi-class fuel co-firing can also reduce the emission of secondary pollutants, which can enable enterprises to generate economic benefits, and can also achieve waste reduction and pollution reduction. purpose. The results of this study show that RDF-5 added to wood chips to waste butter or industrial waste lubricating oil has a calorific value of 7,113 kcal/kg and 6,008 kcal/kg, respectively, and its calorific value is higher than that of bituminous coal with auxiliary fuel. In the technology of preparing RDF-5 for sludge, it can be applied to industries such as waste incineration plants and power plants, which not only reduces environmental pollution, but also increases the competitiveness of enterprises in the industry.
