Abstract

This work investigated the hydrothermal degradation of typical antibiotics present in swine manure (SW) under varying reaction parameters and evaluated the potential of hydrothermal carbonization (HTC) products as high-value carbon materials and liquid fertilizers. The results indicate that doxycycline, sulfadiazine and enrofloxacin were completely degraded under the HTC condition of 260 °C and 40 min, while the optimal HTC conditions for SW were identified as 300 °C, 40 min, and a solid-liquid ratio of 0.1 g/mL. Analysis of the HTC products revealed that hydro-char exhibited favorable surface morphology, a high degree of carbonization, the ability to stabilize heavy metals, a high higher heating value (HHV), and excellent thermal stability. Furthermore, the hydrothermal wastewater complies with discharge standards in terms of heavy metal content, antibiotic concentration, and drug-resistant bacteria content. It also contains significant amount of nitrogen and potassium, along with moderate phosphorus content, highlighting its potential as a liquid fertilizer. This study provides novel insights into the harmless and resourceful utilization of SW and can also serve as a valuable reference for the treatment of other organic waste.
