The present invention provides a membrane bioreactor for deep-sea cold seeps. The bioreactor is used for simulating a biomembrane growth process during anaerobic oxidation of methane (AOM) in the cold seeps and monitoring changes of environmental conditions thereof. The present invention further provides an online environmental parameter measurement system for a membrane biological reaction in the deep-sea cold seeps. The system includes a fluid supply unit used for generating saturated methane fluid and injecting the saturated methane fluid into the membrane bioreactor for the deep-sea cold seeps at a microflow, and a pressurization system used for ensuring stability and consistency of internal environmental pressure of the system in a simulation process.

The present invention provides a system and a method for simulating formation and evolution of a deep-sea cold seep ecosystem. Simulation of the cold seep ecosystem is realized and a unit above seabed interface, a seabed interface ecosystem simulation unit, and a subsea interface unit is formed through the system, which provides environmental conditions for evolution of the cold seep ecosystem. At the same, the primary succession and secondary succession of the ecological cold seep system are simulated through the environmental condition control equipment, the sampling cabin, and the seabed current injection system, and the formation environment of the system is remodeled in situ, thereby effectively shortening the period of field observation to research the cold seep ecosystem. The system can not only observe formation and evolution of the cold seep ecosystems, but also grasp key feature points in the development process for the real-time sampling and analysis, which broadens the depth of the cold seep ecosystem research.
