[0005] But this arrangement method also has its shortcomings, because the air flow is only decomposed into countless fine air bubbles and floats up, so that the oxygen in the compressed air flow can only be dissolved into the sewage pool as much as possible, but it cannot make the pool water The beneficial bacteria and the sewage are fully stirred and mixed, which affects the effect of sewage treatment

Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] As shown in Figure 1. The tumbler 2 is vertically fixed on the middle part of the support 6 by the fixed plate 13, and the support 6 is fixedly installed on the foundation 12. The tumbler 2 is a cylindrical structure with openings at both ends, as shown in FIG. 2 . The tumbler 2 can also be other structures with open inner cavities at both ends, such as square tubes or tubes with curved outer contours. The lower end of the tumbling device 2 is located in the sewage and near the surface of the mud at the bottom of the pool.
[0030] The situation of sewage treatment in different occasions is quite different. In order to increase the strength of silt tumbling, two or more sets of tumbling devices 2 can be installed in one device, and fixed on the bracket 6 side by side, as shown in FIG. 3 .
[0031] A churning trachea 4 is arranged in the inner cavity of the ch...

The efficient rotating and mixing aerator capable of raising the oxygen content of sewage and promoting the mixing between the sewage and sludge under sewage includes rack, aerating device and aerating pipeline connected to the aerating device. The aerating pipeline fixed on the rack is connected to the air source. The efficient rotating and mixing aerator features that it includes also one sludge and sewage turning device, which includes one or several vertical turning units with open-mouthed inner cavity and turning air pipe connected via the aerating pipeline with the air source. The present invention can excite and utilize the pollutant eliminating capacity of the aerobic bacteria inside sewage and sludge effectively to raise sewage treating effect and has the features of low power consumption and high efficiency.
Description
technical field [0001] The invention relates to sewage treatment equipment, in particular to an aeration device for urban sewage treatment. Background technique [0002] In the sewage treatment process, the aeration process is the core technical process, and the effect of the aeration process will directly affect the efficiency and purification effect of sewage treatment. In order to increase the oxygen utilization rate of aeration, people hope that the aeration airflow can be as fine as possible in the water. In order to make the air bubbles finer, people use pores to vent, and in order to get as fine air bubbles as possible, people make the pores finer and finer. , although the air bubbles obtained are very fine, but according to the principle of pore diffusion, when the pores are finer, the exhaust resistance will increase accordingly, which will inevitably increase the air source pressure, which will reduce the operating efficiency of the blower equipment; at the same ti...
