The invention discloses an online detection technology and equipment for a maleic anhydride reaction system. The online detection technology and equipment comprise a reactor shell, an oxygen concentration detection device and a raw material input assembly, wherein the oxygen concentration detection device is arranged in the reactor shell, and the raw material input assembly is arranged in the inner wall of the bottom of the reactor shell; according to the online detection technology and equipment for the maleic anhydride reaction system, the oxygen concentration in a reactor can be effectively detected through the oxygen concentration detection device, the detection of oxygen concentration in each section and layer of the reactor is realized by driving an oxygen concentration sensor to rotate, rise and fall in the reactor, the detection is more accurate, the time or rate of oxygen introduction is controlled by a detected numerical value, and side reaction consumption of produced maleic anhydride caused by exc
