The Effective Method for Processing Sewage Sludge for Reuse as Fertilizer
https://doi.org/10.18412/1816-0395-2024-9-22-27
Abstract
The results of studies assessing the chemical composition of various sewage sludges generated at wastewater treatment plants are presented. The features of the enzyme-cavitation method of wastewater biological treatment are considered, and a comparative characteristic of the composition of sludge is given depending on the method of purification and treatment. The obtained sludges were tested using the proposed processing method, as an independent fertilizer and together with natural zeolite. It was found that adding sewage sludge and zeolite to the soil allowed to achieve the best results and increase the productivity of spring barley used as an experimental crop.
