Reduction and Heavy Metal Stabilization of River Sediment by Hydrothermal Treatment

Figure 1

Influence of hydrothermal condition on organic reduction and COD of hydrolysate: (a) at 3 h of hydrothermal time, the hydrothermal temperatures were set at 180, 200, 220, 240, 260, and 280°C; (b) at 260°C of hydrothermal temperature, the hydrothermal times were set at 0.5, 1.5, 3, 4.5, 6, and 7.5 h.
