Investigation of Sewage Sludge for Obtaining Organomineral Fertilizer
https://doi.org/10.18412/1816-0395-2023-4-17-21
Abstract
A technology for obtaining organomineral fertilizer based on sewage sludge from chemical enterprises is proposed, which allows increasing soil fertility due to the fine structure of bio-coal obtained during pyrolysis of sewage sludge, which retains nutrients in soils for a long time. Studies of sewage sludge before and after pyrolysis for compliance with agrochemical indicators of organic fertilizers according to GOST R 54651-2011 "Organic fertilizers based on sewage sludge" are presented. A method for obtaining organomineral fertilizer by mixing activated sludge with phosphorous flour and sawdust is proposed to ensure the stability of indicators according to the required values according to GOST criteria.
