Combined type biodegradation reaction simulation device

The invention provides a combined type biodegradation reaction simulation device. According to the combined type biodegradation reaction simulation device, an inner degradation reactor is placed in an external ventilation separation cabinet and is a rectangular semi-sealed or full-sealed device; the inner degradation reactor is internally provided with an internal circulating water power system, a water inlet pump and a temperature control module, and comprises a degradation reaction region I, a water quality detection region II and a hydrodynamic force buffering region III which are separated by a filtering device; the degradation reaction region I is a region for degradation reaction of a living body; the water quality detection region II is internally provided with a series of sensors for monitoring water body parameters in real time; the power of a water pump in the hydrodynamic force buffering region III is slowed down and uniformly dispersed; the external ventilation separation cabinet is internally pro
