最近,有关资源再利用的事业又兴旺起来,用过的废旧干电池(这里不包括已进行分别回收的氧化银一次性电池)应当成为回收的主要对象之一。 1983年据通产省机械部门统计:日本干电池年流通量约是6万吨,其中含有有用金属锌1.5万吨,锰0.8万吨,铁1万吨,水银50吨,不过实际上在处理这些干电池时,当然要考虑到水银对环境的污染 Recently, the cause of re-use of resources has thrived again. Used and used dry batteries (excluding silver oxide disposable batteries that have been separately recycled) should be one of the main targets for recovery. According to statistics from the Machinery Department of the MITI in 1983, the annual circulation of dry-cell batteries in Japan is about 60,000 tons, of which there are 15,000 tons of useful metallic zinc, 8,000 tons of manganese, 10,000 tons of iron and 50 tons of mercury, but these are actually handled Of course, taking into account the mercury pollution of the environment when dry batteries
