the bottom of the air cylinder 204 an opening at the upper part of the base 6 is connected with the air cylinder 204 and openings on the side surface of the base 6 are connected with submersible hollow shaft motors 602 respectively a propeller 604 is coaxially connected with each of the submersible hollow shaft motors 602 a hollow structure is adopted inside the base 6 the openings on the side surface of the base 6 are used as the channel for uniformly distributing a compressed air source and the number of the openings can be 2 4 or more the air pressurized through the air compressor 206 flows through the air cylinder 204 via the three way pipe 203 and then is simultaneously sprayed and diffused around through shaft holes of hollow transmission shafts of the submersible hollow shaft motors 602 connected with the openings on the side surface of the base 6 respectively so that the uniform aeration is carried out in sewage the aeration is more uniform and more stable and the serration efficiency is improved the aeration ship further comprises an aeration system lifting device a disinfectant generator a ship body propulsion apparatus and a ship body steering device in a first embodiment of the aeration system lifting device as shown in fig5 the aeration system lifting device comprises the hydraulic station 207 hydraulic pipes 208 the lifting oil cylinder 210 a piston 211 an upper connecting.
