【Objective】Targeting the manure treatment challenges in animal husbandry, this study explored a novel, high-efficiency, and environmentally friendly manure treatment technology. The goal was to realize the reduction, harmlessness, and resource utilization of animal husbandry, and offer tech- nical support for the sustainable development of the animal husbandry. 【Method】In this study, the en- hanced off-site fermentation bed technology was employed to treat manure using complex microbial flora. Operation parameters of the fermentation bed, were optimized through microbial colony recombination to boost the efficiency of manure treatment. 【Result】After three months of operation, the organic matter con- tent of the fermented mattress material reached 36. 7% , the total nutrient content was 6. 68% , the pH was 7. 85, the number of fecal coliforms was 23, and the mortality rate of ascaris eggs was 99. 3% . The heavy metal content was relatively low (TAs = 6. 68 mg / kg, TCd = 0. 39 mg / kg, TPb = 24. 26 mg / kg, TCr= 78. 73 mg / kg, THg = 0. 18 mg / kg). These key indicators outperformed China
