【摘要】 煤矸石中含有有机质和无机营养元素,可将其制成肥料,一方面解决煤矸石堆放带来的环境污染问题,另一方面将煤矸石变废为宝。国内外学者对煤矸石制肥料进行研究,主要研究内容是选择无机矿物、化肥、微生物、粪肥、秸秆及污泥中的一种或几种与煤矸石混合制肥,同时还研究了降低或者控制煤矸石中重金属的措施。主要针对煤矸石制肥料的方法及效果进行综述及评价,并且对研制过程和方向提出建议。更多还原

【Abstract】 Coal gangue can be made into fertilizer because it contains organic matter and inorganic nutrient elements, on the one hand, it can solve the environmental pollution problem caused by coal gangue stacking, on the other hand, it will turn waste into treasure. Scholars at home and abroad have studied the preparation of fertilizer from coal gangue, and the main research contents includes selecting one or several materials in inorganic minerals, chemical fertilizer, microorganisms, manure, straw and sludge mixed with coal gangue to produce fertilizer, and studying measures to reduce or control heavy metals in coal gangue. In this paper, reviews and evaluates of the methods and effects of making fertilizer from coal gangue, and suggestions on the development process and direction were put forward.更多还原
