Abstract

Ar anaerobic-aerobic reactor for preparing composit is composed of fermentor, ventilation system, stirring system, and heating system. The said fermentor has a sieve plate to divided it into thepartsand a stirring axle driven by motor. Its fermenting chamber is a sealed unit with circulating water both jacket for heating it and liquid inlet and outlet, and features that the anaerobic digestion and aerobic reaction are conduted in a single equipment.

Description

1. Technical field [0001] The invention relates to a garbage composting reaction device, in particular to an organic matter anaerobic and aerobic integrated composting reaction device. 2. Background technology [0002] Aerobic composting of municipal waste after anaerobic digestion can make high-quality organic compost. At present, due to the limitation of fermentation equipment, in waste treatment, only anaerobic digestion is used to produce biogas, or only aerobic composting is performed. In rural areas, anaerobic digestion is used to produce biogas, but biogas residues are directly used as fertilizer without aerobic composting. With anaerobic digestion, the compost quality is also poor. The devices for anaerobic digestion to produce biogas include air bag type, hydraulic type, floating cover type and egg-shaped fermentation bins, etc.; the devices for aerobic composting include tower type and drum type fermentation bins. None of these devices can complete anaerobic dig...
