NOVELTY - High temperature anaerobic digestion bio-reaction system comprises a high temperature anaerobic digestion reactor for degrading nitrosodimethylamine in waste water in high temperature environment so as to produce marsh gas and biogas slurry, a marsh gas outlet, a biogas outlet, a stock solution inlet, and a high efficiency heat energy recycling device, comprising multiple heat exchange units and a heat preservation units, which are independently separated. The heat exchange unit is provided with a discharge fluid flow channel and a heating fluid flow channel.    USE - Used as a high temperature anaerobic digestion bio-reaction system.    ADVANTAGE - The system meets the requirements of high-temperature reaction of sewage, does not consume external energy, and can operate continuously.    DETAILED DESCRIPTION - High temperature anaerobic digestion bio-reaction system comprises a high temperature anaerobic digestion reactor for degrading nitrosodimethylamine in waste water in high temperature environment so as to produce marsh gas and biogas slurry, a marsh gas outlet, a biogas outlet, a stock solution inlet, and a high efficiency heat energy recycling device, comprising multiple heat exchange units and a heat preservation units, which are independently separated. The heat exchange unit is provided with a discharge fluid flow channel and a heating fluid flow channel. Each two adjacent heat exchange units are provided with a first connecting channel and a second connecting channel. The first connecting channel is connected with two adjacent heat exchange units set with discharge fluid flow channel. The second connecting channel is connected with heating fluid flow channel of two adjacent heat exchange units. Multiple heat exchanging units are connected in series. The exhaust fluid flow passage and a connecting passage are composed of biogas slurry channel. The heating fluid flowing channel and the second connecting channel is composed of a raw liquid passage. The liquid channel one end is connected to biogas slurry outlet and sewage source. The discharge fluid flow channel and heating fluid flow channel exchange heat so as to heat wastewater. A heating device comprises a marsh gas combustor and a heating pipe, which is connected with the liquid channel and the other end of the raw liquid inlet. The gas burner is connected with marsh gas outlet. The heating gas pass through the wastewater pipe.
