The invention relates to the technical field of advanced sewage treatment, and provides an air flotation device with oil-water separation function. The device comprises an inner cylinder body and an outer cylinder body arranged coaxially, the inner cylinder body and the outer cylinder body constitute an air flotation reaction zone, and also includes an ozone oxidation zone, and the ozone oxidation zone is fed with raw water and ozone, so The upper port of the ozone oxidation zone is provided with an oil collecting groove, the oil collecting groove is communicated with the oil discharge pipe, the lower port of the inner cylinder body is passed into ozone-dissolved gas water, and the ozone oxidation zone is connected to the lower port of the inner cylinder body. Connected, set up ozone oxidation zone, use ozone to separate oil and water, and also use ozone to improve the cohesion performance of organic matter, so that the waste water after oil and water separation is convenient for coagulation and sedimentation reaction before passing into the inner cylinder, and the effect of sewage treatment is enhanced. |
