课题来源:1节5号电池弃于土壤中,可使1 m2的土地失去农用价值:1颗“纽扣”电池中的污染物全部释放后,会污染60万升水,废旧电池已成为我们生存环境的一大杀手!我国年消费电池70亿-80亿节。回收率不足1%,由于回收再利用成本较高,所以现在的处理方式仍是以填埋为主,变分散污染为集中污染。我们拟探讨解决干电池污染的办法,研究思路是从源头做起,减少干电池的使用量,我们调查了不同类型的学校和家庭,发现干电池的主体消费者是学生,通过测试市场上各种电池的性能,对比优缺点,选择普
Subject Source: 1 Section 5 batteries were discarded in the soil and could cause 1 m2 of land to lose its agricultural value: After releasing all the pollutants in a “button” battery, it would pollute 600,000 liters of water. Waste batteries have become our living environment. One of the killers! China’s annual consumption of batteries 7 billion - 8 billion. The recovery rate is less than 1%. Due to the high cost of recycling, the current treatment method is still landfill-based, and the decentralized pollution is centralized pollution. We intend to explore ways to solve the problem of dry battery pollution. The research idea is to start from the source and reduce the use of dry batteries. We investigated different types of schools and families and found that the main consumers of dry batteries are students and passed tests on various batteries on the market. Performance, comparison of advantages and disadvantages, choice of general
