Abstract: The present disclosure discloses a device for electrochemically assisted aerobic composting of organic solid waste and method therefor. The aerobic composting device includes a compost bioreactor, a working electrode, an auxiliary electrode, and a reference electrode. The working electrode is situated on the inner wall of the compost bioreactor, and the reference electrode is situated between the working electrode and the auxiliary electrode. The bottom of the compost bioreactor is provided with a ventilation pipeline with an aeration head. A method for electrochemically assisted aerobic composting of organic solid waste by using the device is also disclosed. By performing electrochemically assisted composting through the composting device of the present disclosure can enrich and utilize electric energy microorganisms to promote the progress of the redox reaction in the compost pile, quickly increase the temperature of the compost, shorten the compost period, and increase the compost maturity.
