Modularized impulse type aerating device, standard aerating system module and filter system

The utility model provides a modularized impulse type aerating device. According to the device, after the continuous input of a small-flux air stream, the impulse type aerating effect that a large-flux air stream is released uniformly and instantly to generate large bubbles is realized, the aerating cleaning effect of a film is improved, and the energy consumption of the device is lowered, and moreover, the device can prevent aerating failure caused by blocking. The utility model further provides a standard aerating system module. The module comprises one or more modularized impulse type aerating devices disclosed by the utility model, and according to practical usage requirements, in the standard aerating system module, the modularized impulse type aerating devices at any position and with random quantities can release air streams with different frequencies and different fluxes so as to realize the aims that various aerating intensities are achieved, the aerating cleaning effect of the film is further improved, and the energy consumption of the device is reduced. The utility model further provides a filtering system, which is an external casing type film filtering system or an immersed type film filtering system, and comprises one or more standard aerating system modules disclosed by the utility model.
