New type efficient rotary-mixing aeration device

The utility model provides a novel efficient rotary mixing aeration device, which not only can effectively improve the oxygen content of sewage, but also can sufficiently mix the sewage and the underwater sludge simultaneously. The utility model comprises a support, an aerator and an aeration pipeline communicated with the aerator, wherein the aeration pipeline is communicated with an air source and is fixed on the support, and the utility model is characterized in that the aerator also comprises a sludge water turnover device. The sludge water turnover device comprises one or a plurality of vertically arranged turnover devices, the inner part of each turnover device is provided with an inner chamber, wherein both ends of the inner chamber are open, and a turnover air pipe is arranged in the inner chamber of each turnover device. One end of the turnover air pipe is positioned in the inner chamber of the turnover device, the other end of the turnover air pipe is communicated with an air pipe, and the air pipe is communicated with the air source. The utility model sufficiently excites and uses the dirt removing capacity of dirt removing aerobe distributed in the sewage and the sludge, improves the effects of sewage treatment, and has the characteristics of energy saving and high efficiency.
