成都理工大学硕士学位论文 成都理工大学硕士学位论文 II II A Experimental Study of Solid Waste on the Mineral Composition and Its Improving on Soil Introduction of the author: Wang Biao, male, was born in June, 1983 whose tutor was Professor Yangjin. He graduated from Chengdu University of Technology in Mineral Materials major and was granted the Master Degree in June,2010 Abstract With the rapid increase of the solid waste, it not only occupy large areas of land resources due to pile up, but also cause serious environmental pollution, and even trigger landslides, mudslides and other secondary geological disasters. In addition, with the development of economic and the level of the the city improvement, people on the land leads to excessive production, impoverishment of the soil, or the number reclamation soil themselves are very fragile, so that it have not the coordination and the supply of nutrients for the plant capacity. Therefore, the solid wastes improve soil to bring about social, economic and environmental benefits of vital importance. This subject by Fly ash,phosphogypsum and sludge components and pH value, will start from all proportion to the mixture and then improve three of the barren soil in Jintang county,Qionglai and Pengzhou to the study concluded as follows： (1).Experiments using scanning electron microscopy analysis, and agricultural methods of rock analysis summarizes the three solid waste of fly ash, phosphogypsum and sludge material composition, physical and chemical properties and fertility status, at lase,it inproved that three solid waste have proved improve soil conditions . (2).By the geological background, formation characteristics and features of the fourth line of Pengzhou, Qionglai and Jintang three barren soil,using the X-ray, agricultural chemical analysis and rock analysis, etc,the results showed that quartz and illite in soil share of large, silicate content of more weathered, less fertile, available nitrogen, phosphorus, potassium and soil organic matter co
