随着人类生活水平以及生活质量的不断提高,各种民用、工业垃圾日益增加,已经成为各国的一大公害,鉴于此,废物利用就成了各国竞相开展研究的一个大课题。加拿大和日本相继从粪便和混合废塑料中再生出了柴油和汽油,从而开辟了二次能源开发新途径。加拿大废水技术中心在安大略省哈密尔顿兴建了一个小规模的试验厂,每天可以把一吨干燥的粪便加工转换成两桶动力柴油。其工艺过程分4个步骤。首先,把粪便污物中的水排放掉;接着,用热空气使其干燥;第三,加热到450℃,粪便排出气体后成为灰色的炭状物;最后把气体变成液体,从中获取柴油。至于剩
With the continuous improvement of human living standards and quality of life, a growing number of civil and industrial waste have become a major public hazard in various countries. Therefore, waste utilization has become a major issue for all countries to carry out research. Canada and Japan have successively regenerated diesel and gasoline from manure and mixed waste plastics, opening up new channels for secondary energy development. The Waste Water Technology Center in Canada has constructed a pilot plant in Hamilton, Ontario, that converts one tonne of dry excrement into two barrels a day of diesel. The process is divided into 4 steps. First, the water in the excrement was drained off, followed by drying with hot air. Third, it was heated to 450 ° C and the excrement became gray carbon after the excretion of the excrement. Finally, the gas was turned into liquid and diesel was obtained therefrom . As left
