【Abstract】 A waste residue discharged from Shajiao Thermal Power Plant is the powdery coal ash cov-ering a large area and causing enviro nmental pollution.However,it cont ains a useful composition which is a regenerated resource.If we make ful l use of it,not only can we get much economic benefit,but also the environmental pollution can be redu ced.In this paper,the specific gravity,loose measure weight ,grain size composition and carbon size com position of the ash are analyzed,exploring the ways of collecting the hollow glass mini -beads by means of water flotation.Finally a full exposition of its development and uti-lization is given as well.更多还原
