s1, operating the first on-off control module (4) to enable zero groups, one groups or multiple groups of second photobioreactor pipelines (3) to be communicated with the buffer tank structure (1) to form a loop channel, and culturing photobioreactors through the first photobioreactor pipelines (2) and the second photobioreactor pipelines (3) which are communicated with the buffer tank structure (1);
S2, when the photo-biological culture scale is required to be enlarged, the first on-off control module (4) is operated, so that one or more groups of second photo-biological reactor pipelines which are not communicated with the buffer tank structure (1) currently form a loop are communicated with the buffer tank structure (1) to form a loop.
