Method of preparing composite organic fertilizer from biological pharmacy mycelium sludge

一种应用生物制药菌丝体污泥制备多元复合有机肥料方法

Abstract

The invention discloses a method of preparing a composite organic fertilizer from biological pharmacy mycelium sludge, belongs to the field of sludge recycling, and aims to solve the problems that in the prior art, the biological pharmacy mycelium sludge contains a large amount of antibiotics, cannot be directly buried in soil as wastes, and pollutes the surrounding environment, soil, and plants. The method comprises the following steps: step one, preparing dried mycelium sludge through a microwave method, step two, evenly mixing dried mycelium sludge, added auxiliary materials, and composite fermenting inoculant, blending to obtain materials for fermentation, and carrying out fermentation in a sunlight green house; step three, carrying out aging, drying, and grinding, then adding inorganic elements (nitrogen, phosphor, and potassium), biological potassium bacteria, nitrogen fixing bacteria, phosphor bacteria, and synergist, and finally granulating the mixture to obtain the fertilizer. The sludge mainly made of mycelium is subjected to a pretreatment technology, then a microbial inoculant is added, the fermentation technology is optimized, at the same time nutrients are added; the mycelium residues are used to produce organic fertilizer, the damage of mycelium sludge to the surrounding environment, soil, and plants is avoided, the waste is converted into valuable resources, and the method has an economic value and market prospect.
一种应用生物制药菌丝体污泥制备多元复合有机肥料方法,它于污泥资源化领域,它要解决目前生物制药菌丝体污泥,含有大量的抗生素,无法直接作为废弃物进行填埋,而且对周围环境土壤和植物有损伤的问题。方法:一、采用微波法制备干燥的菌丝体污泥;二、干燥的菌丝体污泥、添加辅料和复合发酵菌剂混拌均匀,得到发酵物料,日光温室大棚进行发酵;三、熟化、烘干、粉碎后添加无机氮、磷、钾元素、生物钾细菌、固氮菌、磷细菌和增效剂,造粒即完成。本发明以菌丝体为主的污泥,通过预处理工艺和微生物菌剂及发酵工艺优化同时添加营养元素,实现利用菌丝体废渣生产有机肥料,对周围环境土壤和植物无损伤,变废为宝,具有经济价值和市场前景。
