AI Technical Summary
Existing technologies are ineffective in suppressing hydrogen sulfide (H2S) pollution during the anaerobic digestion of food waste. Furthermore, conventional methods suffer from high costs, significant impact on methane yield, high safety risks, and insufficient resource utilization.
The system employs slow-release electron acceptor/conductive mediator core-shell microspheres. The core layer consists of nitrates embedded in a polymer, while the shell layer is composed of modified hydrothermal carbon powder and magnetic nano-zero-valent iron. Through synergistic effects, it achieves hydrogen sulfide inhibition, methane production enhancement, and resource recycling.
It achieves efficient in-situ control of H2S, keeping the H2S concentration in the gas phase stable below 50ppm, increasing methane yield by 15%-20%, reducing operation and maintenance costs, and the material is biodegradable with no secondary pollution.
