A hydrolyzer outfeed system includes a hydrolyzer having a hydrolyzer outlet, an intermediate pressure chamber having a pressure chamber inlet and a pressure chamber outlet, and an expansion chamber. A pressure chamber inlet valve selectively communicates the hydrolyzer outlet with the pressure chamber inlet, the inlet valve having an inlet valve cross-sectional area in a fully open position. A pressure chamber outlet valve selectively communicates the pressure chamber outlet with the expansion chamber. The pressure chamber outlet valve has an outlet valve cross-sectional area in a fully open position. The outlet valve cross-sectional area is smaller than the inlet valve cross-sectional area.

A method for restoring and managing a garbage landfill is disclosed. The method comprises: determining a stabilization degree of each garbage dump within the landfill; performing a first garbage treatment step when the stabilization degree of the garbage dump meets a preset standard; performing aerobic stabilization pretreatment when the stabilization degree does not meet the preset standard, followed by a preset second garbage treatment step; performing ecological restoration treatment, so that a restored landfill meets a preset usage standard, wherein the first garbage treatment step is performed in an area adjacent to a garbage dump, and the second garbage treatment step is performed in an area where the garbage dump is located. By combining in-situ and ex-situ restoration, the method achieves harmless, reduced, and resource-based removal of garbage dumps while controlling ecological and environmental impacts, including leachate, odor, noise, and water and soil loss.

The disclosure is directed at a method of treating hard to digest food waste by treating the food waste with a thermal-alkaline hydrolysis process (THP). The THP includes treating the food waste with heat, alkali, and shear for a preselected time to produce a biodegradable feedstock for improved anaerobic digestion.
