一、粉煤灰资源化迫在眉睫据贵州省几个主要燃煤电厂统计,1990年的排灰量已达158万吨,随着一批扩建和新建工程的完工,排灰量还将成倍增长,而我们目前的利用率很低,年利用量只有42万吨,低于全国平均水平。贵州是我国南方煤炭资源最丰富的省份,今后还要大力发展煤电一体化,因此我省今后粉煤灰的排量必将有很大的增长,而目前每年的排放量的增长超过了用灰量的增长,这种局面现在如不采取有力措施,今后问题将越来越严重,将会贻误时机,使今后电力和经济的发展受很大的制约,对社会和环境将产生严重的不良影响。解决粉煤灰问题的最有效最根本的途径就是开展综合利用。资源综合利用已是我国经济建设中一项重大技术经济政策。党中央制定的十年规划和“八五”计划中,对资源节约十分重
I. Fly ash resources are imminent According to statistics from several major coal-fired power plants in Guizhou Province, the amount of ash discharged in 1990 has reached 1.58 million tons. With the completion of a number of expansion and new construction projects, the amount of ash discharged will also increase exponentially. And our current utilization rate is very low. The annual utilization is only 420,000 tons, which is lower than the national average. Guizhou is the province with the most abundant coal resources in the south of China. We will also vigorously develop coal-electricity integration in the future. Therefore, the future of fly ash in our province will surely increase greatly. At present, the annual increase in emissions exceeds the use. With the increase in the amount of ash, if this situation does not take effective measures now, the problems will become more and more serious in the future, and the timing will be delayed, which will greatly restrict the future development of electricity and economy, and cause serious adverse effects on society and the environment. influences. The most effective and fundamental way to solve the fly ash problem is to carry out comprehensive utilization. Comprehensive utilization of resources has become a major technical and economic policy in China’s economic construction. In the 10-year plan formulated by the Party Central Committee and the “8th Five-Year Plan”, it is very important for resource conservation.
