在社会高速发展,人口急骤增加的今天,垃圾的危害也日趋严重地困扰着人们的生活。从另一方面讲,垃圾特别是城市垃圾也已成为一种急待利用的庞大资源。对城市垃圾,传统的处理方法一般是焚烧和填埋。焚烧会污染环境,填埋则又会占用大量耕地,同时也是资源的浪费。综合利用垃圾特别是城市垃圾制造有机肥,已成为世界性的研究课题。目前已见诸报导的有,成套机械堆肥法,高温堆肥技术,即好氧与厌氧相结合发酵工艺及快速堆肥动态发酵工艺。这些技术在付诸实施中,由于
With the rapid social development and the sudden increase of population, the harm of rubbish also increasingly plagues people’s lives. On the other hand, rubbish, especially urban rubbish, has also become a huge resource to be urgently used. Traditionally, municipal waste is incinerated and landfilled. Incineration will pollute the environment, landfill will occupy a large amount of arable land, but also a waste of resources. Comprehensive utilization of waste, especially urban waste to make organic fertilizer, has become a worldwide research topic. Has been reported that there are reports, complete sets of mechanical composting, high-temperature composting technology, that is, a combination of aerobic and anaerobic fermentation process and rapid composting dynamic fermentation process. These technologies are put into practice due to
