A composite ozone flotation integrated device may include a cylinder body, an intermediate cylinder, and a central cylinder which are coaxial. The cylinder body and the center cylinder have a common bottom. The cylinder body and the intermediate cylinder have a common top. The intermediate cylinder is arranged on support channel steel between the cylinder body and the center cylinder. A top of the center cylinder is in the intermediate cylinder. The top of the center cylinder is open-mouthed. An upper part of the cylinder body is provided with a drainpipe. The top of the cylinder body is provided with an inner cylinder exhaust pipe and a slag discharge pipe. An upper part of the intermediate cylinder is provided with an outer cylinder exhaust pipe. A lower part of the center cylinder is connected to a water inlet pipe, a dissolved gas inlet pipe, and a venting and sludge-discharge pipe.
