equipment in Shouguang Vegetable Garden
high solid content in anaerobic fermentation and the feed system adopts the vertical
and spiral feeding mode, which can lift materials vertically by 5 m. Conical-bottom
discharge system with assembled cylindrical skirt support is used for discharge and
a horizontal slurry pump is designed for reflux and distribution of biogas slurry.
This project in Zhanjiang, Guangdong province, China takes livestock manure
and fruit and vegetable planting wastes as main fermentation materials and used
energy-saving dry anaerobic fermentation equipment for dry anaerobic fermentation
treatment in the scale of 8 m
3 . Biogas produced through fermentation is converted
into electricity and heat through biogas lamps and biogas stoves and supplied to
the garden (Fig. 5.4). The contents of organic matters and trace elements required
in crop growth in biogas fertilizers are high, which can effectively improve soil
conditions, reduce plant diseases and insect pests and improve fruit and vegetable
quality. Biogas fertilizers produced in the project provide nutrients for the growth of
fruits and vegetables in the garden.
