Abstract

The invention provides a system and method for anaerobic digestion and biogas purification of waste fruits and vegetables. The system comprises five component parts including a charging unit, an anaerobic digestion unit, a biogas slurry filtering unit, a biogas residue drying unit and a biogas purifying unit. The system generates biogas through an anaerobic digestion process, and the generated biogas is used for drying biogas residue to prepare pellet fuel. The system further uses a technical system and method for preparing biogas through a hollow fiber membrane system. The system and method allow efficient conversion of waste and covert waste fruits and vegetables to biogas and pellet fuel through anaerobic digestion and a hollow fiber membrane separation system.

Description

technical field [0001] The invention relates to the field of protective equipment, in particular to a system for anaerobic digestion and biogas purification and purification of waste fruits and vegetables, and a method for anaerobic digestion and biogas purification and purification of waste fruits and vegetables. Background technique [0002] In recent years, due to the adjustment of industrial structure and the rapid development of intensive planting of fruits and vegetables, the massive production and enrichment of fruit and vegetable waste has constituted a serious threat to farmland, water bodies, fruit and vegetable distribution markets and other human settlements, and has become an unavoidable Neglected sources of pollution. According to statistics, China produces as much as 100 million tons of fruit and vegetable waste every year, most of which are not used as resources and are discarded as garbage or discharged into the environment, which brings risks to the air, wa...
