Abstract
Chicken breeding facilities generate substantial quantities of chicken manure during their operation. Consequently, the processing of organic waste from these facilities is a pressing concern. In this work, a study was conducted on the selection of the composition of chemical reagents for processing chicken manure for the purpose of its subsequent use in the production of complex fertilizers. Research has demonstrated that a composition comprising ammonium persulfate, formaldehyde, and peracetic acid, as well as a composition containing sulfuric acid, sodium hypochlorite, sodium hydroxide, and lime milk, have a deodorizing effect on chicken manure in both laboratory and industrial conditions. From the standpoint of the rapidity with which the deodorizing effect is initiated, a formulation comprising ammonium persulfate, formalin, and peracetic acid is preferable. The deodorization effect was observed in 100-liter litter samples after a treatment period of 40 minutes. Both compositions demonstrated effective retention of their deodorizing and disinfection properties over a duration of up to 30 days. The utilization of chicken manure in this manner does not constitute a threat to the environment and can be used as an organic component of complex organomineral fertilizers.
