The invention discloses a sewage treatment system which comprises m reaction tanks, m dosing devices, m conveying pipelines, m concentration detectors and m-1 first adjusting modules, one conveying pipeline is connected with the head reaction tank, and the m reaction tanks are sequentially connected in series through m-1 conveying pipelines; the m dosing devices are arranged in one-to-one correspondence with the reaction tanks, and the dosing speed of the dosing devices is gradually reduced from the dosing device at the head part to the dosing device at the tail part; the m concentration detectors are respectively arranged on the conveying pipeline; the m-1 first adjusting modules are electrically connected with the latter m-1 dosing devices, and each first adjusting module adjusts the feeding speed of the dosing device according to the concentration difference of pollutants entering and exiting from the previous reaction tank. The dosing speed of the dosing devices is gradually reduced from the dosing device
