人口增加,垃圾、污水、废气等废物(或称废污,废弃物)也在增加,但土地不增加,这意味着人类活动的净土在减少。废物直接污染环境,引起了人们的关注。随着新技术的出现,一些废物已能够转化为财富;还有一些废物人们正在研究新的对策。废物管理技术已经逐渐形成一门新兴的学科,同时也成为世界上发展最为迅速的产业。 1990年8月和1991年3月,澳工商技术部先后发表了两份关于废物管理技术的报告,前一份着重液态废物,后一份重点是固体废物和空中废物。这两份报告内容丰富,可供国内环境和废物管理部门参考。
As the population increases, wastes such as waste, sewage, and waste gas (or waste, waste) also increase, but land does not increase, which means that the net amount of human activities is decreasing. Waste directly pollutes the environment, causing people’s concern. With the advent of new technologies, some wastes have been able to be converted into wealth; there are some waste people are studying new countermeasures. Waste management technology has gradually formed an emerging discipline and has also become the fastest growing industry in the world. In August 1990 and March 1991, the Department of Commerce, Industry and Commerce of Australia released two reports on waste management technology. The former focused on liquid waste, and the latter focused on solid waste and airborne waste. Both reports are rich in content and can be used as references for domestic environmental and waste management agencies.
