气化渣在土壤改良中的应用研究进展
Research Progress on the Application of Coal Gasification Slag in Soil Improvement
摘要
Abstract
Coal gasification is one of the effective ways to convert coal into synthetic gas,but the annual production of gasification slag in Chi-na is huge and has not been effectively disposed and utilized.With the increasingly serious problems of resource waste and environmental pol-lution caused by gasification slag,there is an urgent need to find efficient and reasonable ways to utilize gasification slag resources.At present,the comprehensive utilization of gasification slag resources has problems such as low utilization rate,high cost,and poor scale efficiency,and a mature resource utilization system has not yet been formed.Therefore,in recent years,scholars have proposed new ideas for using gasifica-tion slag,especially fine slag,for soil improvement due to its unique structure and properties.Gasification slag has the characteristics of large surface area,porous structure,large particle size,good water holding performance,and high C and Si content.It can be used as a silicon fer-tilizer,composting additive,humic acid slow-release agent,soil amendment,etc.The advantages,disadvantages,and effects of gasification slag application in soil improvement were analyzed,and future research directions and problems were pointed out.关键词
