项目摘要

In this research, in order to recycle used products, which contain valuable resources and toxic metals, industrial waste incineration kiln was focused and investigated positively under cooperation with conventional waste treatment industries. Two kinds of researches were done in order to develop a new engineering system for of valuable and toxic substances ; "material flow analysis of used product containing valuable resources and toxic metals and its environmental load potential analysis" and "development of safety incineration technique of circuit board containing valuable resources and toxic metals".In "material flow analysis of used product containing valuable resources and toxic metals and its environmental load potential analysis", number of domestic shipment, product average weight, number of domestic disposal, and domestic disposal weight were estimated for 95 items of home electronic products. Moreover, products with large domestic disposal weight were collected, disassembled, and measured material contents and elution amounts of valuable resources and toxic metals.In "development of safety incineration technique of circuit board containing valuable resources and toxic metals", generation of toxic substances produced in incineration of flame retardants which were contained in circuit board and covering body of electronic product. Especially, toxic incineration products, such as carbon monoxide (CO) and semi-non volatile organic brominates (SNVOBr), were measured in various experimental conditions, such as type of circuit board, type of flame retardant, amount of incineration waste, incineration temperature, gas contact time, and so on.

在这项研究中，为了回收包含有价值的资源和有毒金属的二手产品，工业废物焚化窑是在与常规废物处理行业合作的积极调查的。为了开发有价值和有毒物质的新工程系统，进行了两种研究； “使用有价值的资源和有毒金属及其环境负载的潜在分析的材料流量分析”和“电路板安全焚化技术的开发，其中包含有价值的资源和有毒金属”。在“使用有价值的资源和有毒金属的物质流量分析”中，含有宝贵的资源和有毒金属及其环境负载及其环境负载的潜在分析，产品的平均货物，国内量化量和国内施加量的数量为95。此外，收集，拆卸具有较大家庭处理重量的产品，并测量的材料内容和洗脱量的有价值的资源和有毒金属。在“开发含有宝贵资源和有毒金属的电路板的安全焚化技术”中，产生的有毒物质在电路板和盖板中包含的燃烧式弹药板中产生的有毒物质。尤其是，在各种实验条件下，例如，有毒焚化产物（例如一氧化碳（CO）和半挥发性有机溴化物（SNVOBR））在各种实验条件下进行测量，例如电路板类型，阻燃类型，焚烧量，焚烧量，焚化剂，焚化度温度，气体接触时间，等等。
