Project Background and Treatment Objectives
The Hefei Kitchen Waste Treatment Project belongs to the organic waste scenario, located in Anhui, with a processing capacity of 400 t/d.
The Hefei Xiaomiao kitchen waste treatment project began construction in 2020 and is currently in trial operation. The designed processing capacity is 400 t/d. Plant construction includes food waste pre-treatment, kitchen waste pre-treatment, dry anaerobic digestion, wet anaerobic digestion, wastewater treatment, biogas purification, and biogas power generation systems.
The kitchen waste pre-treatment process adopts “bag breaking + two-stage screening + magnetic separation + pressing.” After impurity removal, the organic matter enters the dry anaerobic digestion system, while the liquid fraction, after sand and impurity removal, enters the wet anaerobic digestion system. The biogas generated by the anaerobic system enters the boiler system for heat production or is integrated into the grid for power generation.
The digestate produced by the anaerobic system, after dewatering, is consolidated with impurities screened from the sorting workshop and transported off-site for incineration.
Process Route and System Configuration
Centered around project treatment objectives, the solution focuses on process organization, core equipment coordination, and material sorting pathways, forming a stable treatment and resource recovery flow.
The project has a designed processing capacity of 400 t/d. Plant construction includes food waste pre-treatment, kitchen waste pre-treatment, dry anaerobic digestion, wet anaerobic digestion, wastewater treatment, biogas purification, and biogas power generation systems.
