The utility model discloses an energy recovery anaerobic sewage treatment system which comprises a water pump room, a lifting water pump is arranged in the water pump room and communicated with an anaerobic treater through a water inlet pipe, and cold channels of a recovery heat exchanger and a heating heat exchanger are sequentially arranged on the water inlet pipe in the water inlet direction. The anaerobic treater is communicated with a heat channel of the recovery heat exchanger through a discharge pipe, the heat channel of the recovery heat exchanger is communicated with follow-up treatment equipment through a follow-up pipe, and the boiler room is communicated with a heat channel of the heating heat exchanger through a hot water pipe. The utility model has the beneficial effects that by taking treatment of 15000 tons of sewage every day as an example, the water temperature of the water outlet pipe is 35 DEG C and the water temperature of the inlet of the water inlet pipe is 15 DEG C in anaerobic treatme
