The system includes a water electrolysis subsystem and an SNG subsystem. The water electrolysis sub-system includes a water electrolysis cell, an oxygen gas tank, and a hydrogen gas tank. The electrodes in the water electrolysis cell are connected to a power output end of a power supply subsystem. Inputs of the oxygen gas tank and the hydrogen gas tank are respectively connected to an oxygen gas collection pipe and a hydrogen gas collection pipe, which are respectively used for collecting oxygen gas and hydrogen gas that are generated from the water electrolysis cell. A methane gas outlet of the SNG subsystem is connected to a bioreactor being a methane oxidizing bacterium preparation reactor. The power supply subsystem includes a multi-energy cooperative power supply apparatus and a power supply network. In the system, the oxygen gas and hydrogen gas, which are generated through water electrolysis hydrogen production, are used for completely or partly applied in an air separation system and a water gas shift system. Because the hydrogen gas, quantity of generated CO2 in a water gas shift process is greatly reduced, and theoretically, carbon emission is reduced by a half.
