热电厂粉煤灰是火力发电厂以煤为燃料排放的废渣,据不完全统计,我省每年排出粉煤灰量高达100多万吨。为此每年都要花费巨额的排灰费用,占用大片土地,电厂及粉煤灰场附近灰尘飞扬,危害工业生产和居民生活。我们从1977年开始研究粉煤灰的处理利用工作。一、试验材料与方法整个试验于1977—1979年在太原南郊、晋城、永济3个县、区5个大队的两种土壤质地(粘土质、砂土质)上进行。供试作物有小麦、玉米、水稻、棉花,试验小区面积为0.05亩,
Thermal power plant fly ash is coal-fired power plant thermal power plant emissions, according to incomplete statistics, the province discharges up to 100 million tons of fly ash each year. To this end, they have to spend a huge amount of ash discharge costs every year, occupying a large area of land, flying dust near power plants and fly ash fields, endangering industrial production and residential life. We started in 1977 to study the handling of fly ash work. First, the test materials and methods The entire experiment from 1977 to 1979 in the southern suburbs of Taiyuan, Jincheng, Yongji three counties, five brigades of the two soil texture (clay, sand soil) carried out. The test crops are wheat, corn, rice, cotton, test plot area of 0.05 acres,
