Preparation method of sludge-based artificial soil granules
The invention relates to the technical field of solid waste comprehensive utilization, and provides a preparation method of sludge-based artificial soil granules. The preparation method comprises thefollowing steps that sludge, an inorganic cementing material, plant growth nutrients, a foaming agent and an additive are provided; the sludge, the inorganic cementing material, the plant growth nutrients, the foaming agent and the additive are mixed, and a first mixture is obtained; and granulation treatment is carried out on the first mixture and water to obtain the sludge-based artificial soilgranules. According to the method, the sludge is used as a main component, the inorganic cementing material is used for bonding and solidifying harmful components, it is guaranteed that the artificialsoil granules have enough mechanical strength and internal pore structures, properties are excellent, the method can be used for cultivating plants, high-efficiency recovery treatment and cleaning ofashore sludge are achieved by the method, stacking space and recovery treatment pressure of the sludge are greatly reduced, large-volume recycling of the sludge is achieved, and secondary pollution generated by the sludge is effectively avoided.
本申请涉及固体废弃物综合利用技术领域，提供了一种基于淤泥的人造土壤颗粒的制备方法，包括如下步骤：提供淤泥、无机胶凝材料、植物生长营养质、发泡剂和添加剂；将淤泥、无机胶凝材料、植物生长营养质、发泡剂和添加剂进行混料处理，得到第一混合物；将第一混合物和水进行造粒处理，得到基于淤泥的人造土壤颗粒。该方法以淤泥为主要组分，以无机胶凝材料进行粘合并固化有害成分，保证人造土壤颗粒具有足够的力学强度和内部孔结构，性质优异，能够用于培养植物，该方法实现了高效率回收处理清理上岸的淤泥，大大减少了淤泥的堆放空间和回收处理压力，实现淤泥的大体量回收利用，并有效防止淤泥产生的二次污染。
