Example Embodiment

[0023] The following describes the implementation of the present invention in detail with reference to the drawings and embodiments.

[0024] Such as figure 1 , A bioreactor with online automatic pH regulation, including data acquisition controller 1, alkali storage tank 2, acid storage tank 3, debugging tank 4, and biological reaction tank 5. The volume range of debugging tank 4 is 0.020-20L, and the biological reaction tank 5 can be an anaerobic biological reactor or an aerobic biological reactor. Among them, the data acquisition controller 1 includes a pH acquisition unit 11, a liquid level acquisition unit 12, and a solenoid valve and peristaltic pump control unit 13. The alkali storage tank 2 is connected to the debugging tank 4 through a pipeline with a solenoid valve 21. The pipeline of valve two 22 is connected to the bioreactor 5. The acid storage tank 3 is connected to the debugging tank 4 through a pipeline with a solenoid valve three 31, and is connected to the biolog
