STUDY ON BIOGAS PRODUCTION ENGINEERING IN WHOLE YEAR IN WULITANG, SHANGHAI

Glass greenhouse is used to keep a high temperature environment in the study of biogas production system in Wulitang of Songjiag County, Shanghai. The experience of biogas production throughout year is introduced. It is suggested that biogass production throughout year can be realized by making full use of local sunlight resource and that the greenhouse temperature plays a key important role in the maintenance of normal biogass production throughout year.
