Title:
SYSTEM AND METHOD FOR COOPERATIVE TREATMENT OF GARDEN WASTE AND KITCHEN WASTE
Document Type and Number:
WIPO Patent Application WO/2023/024713
Kind Code:
A1
Abstract:
A system and method for the cooperative treatment of garden waste and kitchen waste. The system comprises a kitchen waste pretreatment system, a garden waste pretreatment system, a mixed inoculation system, a dry anaerobic system and a solid-liquid separation system. The degradation of lignocellulose in garden waste is accelerated by means of a multi-stage mechanical crushing - acetic acid - laccase pretreatment process for the garden waste; moreover, by means of returning a biogas slurry back for inoculation, the anaerobic time is shortened and the biogas yield is increased; and the C/N ratio and the solid content of materials are adjusted by means of recycling biogas residue, such that the problem of material fluctuation of garden waste due to seasonal pruning is effectively solved, and the stability of the system is maintained.
