The invention belongs to the technical field of sludge treatment, and relates to a reaction system for sludge resource utilization. The reaction system comprises: the system comprises a thermal hydrolysis system, an anaerobic fermentation system, a solid-liquid separation system, an acidification filtrate collection system, a mud cake processing nutrient soil system, a biological pond of a sewage treatment plant, a PHAs synthetic fermentation system, a PHAs collection and extraction system and a PHAs drying system; the thermal hydrolysis system, the anaerobic fermentation system and the solid-liquid separation system are sequentially communicated in series; the solid-liquid separation system is communicated with the mud cake processing nutrient soil system and the acidized filtrate collection system in parallel; the acidification filtrate collecting system is communicated with a biological pond of a sewage treatment plant and a PHAs synthetic fermentation system in parallel; the PHAs synthetic fermentation system, the PHAs collecting and extracting system and the PHAs drying system are communicated in sequence. The reaction system improves the resource utilization rate of the sludge. |
