Method.
Background technique
China is that a few is using coal as one of country of main energy sources in the world, and 1998 in China's energy-consuming structure
Cheng Zhong, coal account for 72.9%.Into China's non-renewable energy structure of consumer demand in 2010, coal accounted for 60% or so, it can be seen that, China
Production of energy and consumptio based on coal will not change in a long time.The huge coal-fired environment generated of consumption figure is asked
Topic becomes increasingly conspicuous, and SO is discharged in China within 19982It is 20,900,000 tons, 14,520,000 tons of flue dust；Discharge SO in 19992It is 18,570,000 tons, cigarette
11,590,000 tons of dirt, wherein 75% or more is related with pollution that caused by coal burning.With the increase of large-size thermal power plant, the discharge of China's flyash
Amount surges by 2675.2 ten thousand tons in 1979 to 1.6 hundred million tons in 2000, and flyash is the one kind given off after coal dust firing
Pozzolanic materials also known as flying dust, cigarette ash.The average annual emissions of China's flyash are about 1.8 hundred million tons at present.Whole nation fire now
Fine coal ash quantity is always stored more than 2,200,000,000 tons in power power plant, about 440,000 mu of ash disposal area land occupation and good farmland, but China's fine coal
The utilization rate of ash is only hovered 30% or so always.It can be seen that largely discarded flyash is not used, not only contaminant water
