Abstract: A new type of anaerobic fermentation device with HDPE anti-seepage membrane was developed to solve the problems in high cost of biogas tank construction and low gas producing rate in the winter. The application results received from a large-scale piggery in Putian City of Fujian Province showed that the anaerobic fermentation device with HDPE anti-seepage membrane was convenient in construction, had strong adaptability and strong anaerobic digestion capability. The cost of project was about 1/10 of the same level of biogas digester, and it had a remarkable effect on the digestion and degradation of breeding wastewater and possessed good economic and environmental benefits.
