项目摘要

In Japan, 80%of waste home electrical equipment was recycled by electrical equipment recycling facility under legal methods.And 20%of waste home electrical equipment was treated by balk and incombustible waste crashing facility of local government.In this research, we investigated for electrical waste recycling and treatment.1)Research for material and residue flow of electrical equipment recycling facilityWe investigated 2 facilities. Main flows of each facility were similar. But some part of treatment was different such as printed board. This reason was influences of cost and place of facilities.2)Research for balk and incombustible waste which include electrical wasteWe investigated balk and incombustible waste crashing facility of F city in west area in Japan. Inlet of this facility contained about 10% home electrical equipment. Residue of this facility was tested by leaching test (JLT46), pH dependent test and some characteristic tests. This residue contained some heavy metals. But leaching concentration was lower than standard value. In physical composition, 43% was plastics, 26% was glasses, 19% was stones, 3% was metal and 2% was printed board.We investigated balk and incombustible waste crashing facility of T city in east area in Japan. Contents of heavy metals was different from F city. This reason was thought about the difference of collecting methods and treatment systems.We need to continue some tests and other facilities.

在日本，80%的废旧家电通过合法的方式由电器回收设施回收，20%的废旧家电通过地方政府的废旧和不燃烧的废旧粉碎设施进行处理。在本研究中，我们对废旧电器的回收和处理进行了调查。1)电器回收设施的物流和残渣流动研究。每个设施的主要流量都是相似的。但有些部分的处理是不同的，比如印制板。2)废旧电子垃圾等废旧物品的研究我们对日本西部F市的废旧物品粉碎设施进行了调研。这个设施的进水口有大约10%的家用电气设备。对该装置的残渣进行了浸出试验(JLT46)、pH依赖性试验和一些特性试验。这些残留物中含有一些重金属。但浸出浓度低于标准值。物理成分中，塑料占43%，玻璃占26%，石头占19%，金属占3%，印刷板占2%。F市土壤重金属含量不同。这是考虑到收集方法和处理系统的不同，需要继续进行一些检测和其他设施。
