5 Engineering Application Cases
Fig. 5.2 Demonstration effects of quality improvement of farmlands
Vegetable Garden, Shandong province, China (Fig. 5.3). In addition, this technology
has been promoted and applied in the projects with the scales of 50 and 100 m
3 in
Xinmi, Henan province and Dianchi, Yunnan province, China, respectively.
5.4 Application Case of Energy-Saving Dry Anaerobic
Fermentation Technology
The equipment of dry anaerobic fermentation technology is used for reduction, harmless and resourceful utilization of solid (high concentration) organic wastes. The
equipment can produce biogases by utilizing organic matters, such as kitchen wastes,
household wastes, livestock manure, treatment wastes of agricultural products and
straws. The digested fermentation residues have low water content and high content
of organic matter and can be directly applied to the fields after simple treatment or
made organic fertilizers by further deep processing, without producing secondary
pollution.
In view of the problem that the traditional wet fermentation can produce a lot
of biogas slurries, the equipment can utilize vertical dry fermentation reactor with
