Abstract: At present，the utilization degree of solid waste from livestock and poultry breeding is still not high，composting is one of the important technical means of harmless resources utilization of livestock and poultry manure.However，the production of conventional single organic fertilizer is mainly based on low efficiency，and a large number of livestock and poultry breeding solid waste resources could not be effectively utilized，resulting in environmental pollution.Fly maggot is an efficient biological converter of solid wastes from livestock and poultry breeding.The animal waste could be transformed into fly maggot protein and high quality organic fertilizer.According to characteristics of traditional compost such as low economic benefit，high dependency of auxiliary materials，long treatment cycle and high cost，combined with characteristics of main components and physicochemical properties of animal manure，based on existing bio-conversion process of fly maggot animal manure，through the study of key technology and equipment of industrialization of bio-conversion of solid waste from livestock and poultry breeding，the ecological management and high value utilization of solid waste from livestock and poultry breeding could be realized.
