The present invention provides an anaerobic fermentation system comprising: an anaerobic fermentation tank configured to store and break down a waste to produce the marsh gas; an external circulation pump connected to the anaerobic fermentation tank for sludge break down and circulation, utilizing a scum-extraction pipe and a sludge-extraction pipe to extract a scum and a sludge from the anaerobic fermentation tank respectively; a gas treatment device configured to collect and remove H2S in the marsh gas for corrosion prevention of the following electricity production devices and pipes; a heat exchanger for recycled sludge, which uses the redundant heat from the electricity generator to heat up a cold water. The heated water was used to increase the temperature of recycled scum and sludge through the heat exchanger; and an injection pipe connected to the circulation pump for injecting the heated scum and the heated sludge into the anaerobic fermentation tank under the water level surface of the anaerobic ferm
