摘要
叙述了国内外活性污泥法中需氧量的研究过程及微孔曝气系统的节能技术,对微孔曝气器与穿孔曝管进行对比,证实前者较后者节电44%.
There are 27 million tons ubran solid wastes every day in the global, and 10 billion tons every year.Resources of the wastes contain energy,organic fertilizer,feedstuffs,metals and plastics etc.Energy potentiality is equal to the 10% of world energy consumption,and it is 6×10 16 kJ or 2.4×10 13 kWh.Organic fertilizer potentiality is equal to 1 billion tons fertilizer.Feedstuffs potentiality is equal to 1.9 billion tons grains,it's 3.2 billion tons feedstuffs.It can be retrieved 0.3~0.5 billion tons metals and 0.1~0.2 billion tons plastics from the wastes.The making full use of waste resources can solve the problem of environment and development.
