The article presents research results on obtaining phosphorus granulated fertilizers on the basis of microbiologically activated sewage sludge ashes, ground bones and dried blood from meat industry. Granulation tests were carried out using a laboratory pan granulator as well as on an experimental pilot plant. The aim of the studies was to select the proper composition of the mixture of raw materials and binding agents to obtain granulated fertilizers from waste materials such as MSSA and MBM and bacteria lyophilisate. Obtained fertilizer samples were subjected to physical tests (granulation tests etc.) and quality assessment. The tests confirmed that it was possible to produce granulated phosphate fertilizers using the Bacillus megaterium for solubilization of phosphorus in a simple process.

本文介绍了在微生物活化的污水污泥灰，碎骨和肉类干血的基础上获得磷颗粒肥料的研究成果。造粒测试是使用实验室锅式造粒机以及实验性中试装置进行的。研究的目的是选择原料和粘合剂的混合物的适当组成，以便从诸如MSSA和MBM之类的废料和冻干细菌中获得颗粒肥料。对获得的肥料样品进行物理测试（造粒测试等）和质量评估。这些测试证实，使用巨大芽孢杆菌以简单的方法增溶磷就可以生产颗粒状的磷肥。
