The invention relates to the technical field of preparation of silicon-potassium fertilizer from coal gangue, in particular to a preparation method for preparing microbial fertilizer from coal gangue.
Background
Coal gangue is a solid industrial waste produced in the coal mining and processing process and contains various mineral components. Wherein the kaolin and quartz account for more than 50%, and may also contain other crystalline phase minerals such as illite, chlorite, muscovite, feldspar, pyrite, siderite, hematite, calcite, etc. Wherein the kaolinite, illite, chlorite, muscovite, feldspar and the like belong to the aluminum clay minerals and all show good adsorption performance. The main chemical components of the coal gangue comprise AL2O3, SiO2, CaO, MgO, Fe2O3, K2O, Na2O and the like. The geological age and the area of the coal bed are different, and the content of the chemical components is greatly fluctuated.
However, in China, coal gangue stockpiled in coal enterprises reaches 50 hundred million t, and the emission increases at a rate of not less than 3 hundred million t per year. The annual emission of coal gangue in China is estimated to be not less than 7 hundred million t before 2020. The coal gangue stockpiled throughout the year wastes a large amount of valuable land resources, and also destroys the ecological environment of a mining area, influences the underground water quality of the mining area, destroys landscapes and the like.
During the growth of plants, mineral elements, particularly phosphorus element, potassium element and the like are needed, and the coal gangue is rich in various trace mineral elements, so that the inventor researches a preparation method for preparing the microbial fertilizer by using the coal gangue through long-term experiments.
