Research Progress on Aerobic Composting Technology of Chicken Manure

Abstract:

China's chicken industry is developing towards largescale,intensive and industrialization.As one of the important raw materials of manure,its byproduct chicken manure has become a research hotspot in the development and utilization of biomass energy in new energy.Aerobic composting is one of the most commonly used and most economical and effective treatment methods for manure fertilization.However,traditional aerobic composting has the disadvantages of slow initiation,long cycle,large carbon and nitrogen loss,poor product quality,more odor emissions,antibiotic residues,and excessive heavy metals,which hinder the development of the safe utilization of manure resources.In this paper,the effects of endogenous parameters and exogenous additives on chicken manure aerobic composting and the effects of chicken manure aerobic composting on antibiotic reduction and heavy metal passivation were reviewed,aiming to provide reference for the development and utilization of chicken manure resources and the promotion of green and sustainable development of agriculture.
