Abstract:

This study aims to delve into the current research status and application potential of ultra-high temperature composting technology in the field of livestock and poultry manure treatment. By analyzing pilot studies on ultra-high temperature composting, engineering cases of ultra-high temperature composting, and the quality and application effects of ultra-high temperature compost products, the results show that exogenous heating and the addition of hyperthermophilic bacterial agents are key factors in achieving ultra-high temperature composting, with the addition of hyperthermophilic bacterial agents being particularly crucial. The study indicates that ultra-high temperature composting is suitable for treating livestock and poultry manure of different scales and types, demonstrating economic feasibility. Moreover, the products of ultra-high temperature composting meet the standards for organic fertilizers in China and have shown good effects in cultivation, indicating broad prospects for promotion and application. However, there is still work to be done in exploring and utilizing microbial strain resources for ultra-high temperature composting and demonstrating the field application of ultra-high temperature compost products.

Key words: livestock and poultry manure, hyperthermophilic composting, pilot study, engineering case, composting product, hyperthermophilic bacteria, exogenous heat supply, organic fertilizer standards, promotion and application
