    Abstract: A value-added granulated organic fertilizer produced from poultry litter and biosolids using agglomeration techniques with a pin mixer. The granulated organic fertilizer includes granules biosolids, a nitrification inhibitor, such as dicyandiamide, and a binding agent, such as lignosulfonate, urea formaldehyde, or water. The nitrogen concentration of the granulated organic fertilizer is increased by being fortified with urea. The poultry litter and biosolids formulated into the granulated organic fertilizer aid in flowability, storage, and spreading, while value-added plant nutrient ingredients provide an environmentally safer fertilizer than fresh poultry litter, municipal biosolids and/or many commercially available products commonly used in urban and agricultural systems. The binding agents change the fertilizer granule water soluble phosphorus and nitrogen concentrations and reduce fines and dust. The nitrification inhibitor reduces nitrogen losses via leaching and denitrification, while biosolids decrease water soluble and total phosphorus concentrations in runoff water for environmental protection.

    Abstract translation: 使用聚合技术用针式搅拌机从家禽垃圾和生物固体生产的增值造粒有机肥料。 颗粒状有机肥料包括颗粒状生物固体,硝化抑制剂如双氰胺,以及粘合剂如木质素磺酸盐,脲甲醛或水。 通过用尿素加强,造粒有机肥的氮浓度增加。 配制成颗粒状有机肥料的家禽垃圾和生物固体有助于流动性,储存和扩散,而增值植物营养成分比新鲜家禽垃圾,城市生物固体和/或城市中常用的许多市售产品提供了比环境更安全的肥料 和农业系统。 结合剂改变肥料颗粒水溶性磷和氮的浓度,减少细粉和粉尘。 硝化抑制剂通过浸出和脱氮减少氮损失,而生物固体降低了径流水中的水溶性和总磷浓度,从而达到环保目的。
