Single-phase and two-phase anaerobic digestion of fruit and vegetable waste: Comparison of start-up, reactor stability and process performance

The characteristics and the utilization situation of fruit and vegetable wastes (FVW) were analyzed, and a detailed research conducted on FVW treatment process techniques of single-phase and two-phase anaerobic digestion were summarized. Then the advantages and disadvantages between these two processing techniques are reviewed, respectively. Furthermore, future trends in research and development of FVW treatment process technology have also been briefly discussed, which would provide some new ideas for processing FVW.

Biological Treatment Process

The essence of the two phase anaerobic biological treatment process is to place acid bacteria and methane-producing bacteria in two reactors respectively, where it can provide the optimal conditions for their growth and metabolism, allowing them to live up to their maximal activity, which greatly improve processing capacity and efficiency compared to a single-phase anaerobic digestion. The paper start with the two phase anaerobic digestion process, in order to discuss the development direction of high efficient anaerobic digestion system.

Waste Mixture

Anaerobic digestion of single dairy manure, single vegetable waste, mixture of dairy manure and vegetable waste was conducted to produce biogas. Startup characteristic, leachate parameters and inoculation amount were investigated. The experimental results showed that anaerobic digestion can start up quickly with acclimated thickening sludge as inoculation sludge and 30% was appropriate inoculation percentage. Digestion of single dairy manure and mixture of dairy manure and vegetable waste appeared better buffering ability with higher alkalinity than single vegetable waste. Compared to single digestion of dairy manure or vegetable waste, mixture of dairy manure and vegetable waste is more suitable for anaerobic digestion. Under the conditions of TS=10% and T=(36±1)°C, cumulative biogas production of mixture of dairy manure and vegetable waste is 5281 mL during the period of 30 days and average daily gas production is about 176 mL. These results could provide theoretical data for practical biogas engineering.
