The invention relates to the technical field of agricultural fertilizers, and discloses a preparation method of an agricultural biological organic fertilizer. The preparation method of the agricultural biological organic fertilizer comprises the following steps: carrying out pulse discharge treatment on collected fly ash of a garbage power plant to remove dioxin pollutants; the preparation method comprises the following steps: reacting propylene imine with carbon disulfide to prepare propylene imine into which thiocarboxyl is introduced; under the action of an initiator system, polymer gel is obtained from propylene imine into which sulfo-carboxyl is introduced and an aluminum chloride solution; and carrying out extraction, vacuum drying and grinding on the polymer gel to obtain heavy metal flocculant powder. Mixing the heavy metal flocculant powder, water and fly ash, carrying out solid-liquid separation, and drying the fly ash filtrate to obtain fly ash powder without heavy metals; and mixing the heavy metal-removed fly ash powder, an additive SiO2 and a reinforcing agent Na2O, melting, and carrying out heat treatment to obtain the marble prepared from the fly ash of the garbage power plant.
本发明涉及农业肥料技术领域，且公开了一种农用生物有机肥料的制备方法。所述农用生物有机肥料的制备方法，包括以下步骤：收集的垃圾电厂飞灰经过脉冲放电处理，去除二噁英类污染物；丙烯亚胺和二硫化碳反应，制备得到引入硫代羧基的丙烯亚胺；将引入硫代羧基的丙烯亚胺、氯化铝溶液在引发剂体系的作用下，得到聚合物凝胶；聚合物凝胶经过抽提、真空干燥、研磨，得到重金属絮凝剂粉末。重金属絮凝剂粉末、水和飞灰混合、固液分离，飞灰滤液干燥，得到去除重金属的飞灰粉末；去除重金属的飞灰粉末、添加剂SiO2和增强剂Na2O混合、熔融、热处理，得到垃圾电厂飞飞灰制作的大理石。
