草酸工业是传统的资源、能源依赖型产业。近年来，通过采用一批先进的技术和方法，草酸行业走出了一条节能降耗、资源综合利用的可持续发展之路。草酸生产需要大量的煤、焦炭作为动力和原料，其排放的炉渣含碳量都在１５％～２０％之间。这部分炉渣如果废弃掉，既浪费能源，又 Oxalic acid industry is a traditional resource, energy-dependent industries. In recent years, through the use of a number of advanced technologies and methods, the oxalic acid industry has stepped out of a road of sustainable development featuring energy saving, comprehensive utilization of resources. Oxalic acid production requires a lot of coal, coke as a driving force and raw materials, the carbon content of slag emissions are between 15% to 20%. If this part of the slag is discarded, it will not only waste energy, but also
