Abstract

The environmental pollution problem caused by poultry manure has become a hot issue that needs to be solved globally nowadays. This paper analyzes the environmental impact of different harmful substances in poultry manure from the perspective of ecology and organic agriculture, as well as the potential environmental and economic benefits of poultry manure in secondary use. Through literature analysis method, the author compares and summarizes the advantages and constraints of anaerobic digestion, anaerobic co-digestion, gasification, pyrolysis (thermochemical technology) and cobalt 60 irradiation technology application in sustainability development. The superiority of using cobalt 60 irradiation technology in treating poultry manure is screened out, and corresponding suggestions are made for the stable development of poultry manure, which makes a significant contribution to reducing the pollution of poultry manure to the environment as a way to promote the harmonious development of environment and economy.
