C) foul smell that produces carries through collection, pipeline and the hollow axle of jet aerator is sucked in the water body of aeration tank, and removes repugnant substance by biological degradation.
As the first optimal technical scheme of the present invention, in the steps A, can provide air change rate more than 3 times at the enclosed space of building above the odor source structures, and be controlled at the lightweight covering material height that build odor source structures top by adjustable support bar, thereby change the trapped volume of foul smell.
As the second optimal technical scheme of the present invention, control gas collection district inside and outside differential pressure by the size of regulating gas collection district ventilation opening.
As the third optimal technical scheme of the present invention, among the step B, the transport pipe front end in described connection gas collection district is provided with filter screen, prevents line clogging.
As the 4th kind of optimal technical scheme of the present invention, the setting angle of injector aerator is 30 to 60 degree, the water screw submergence of aerator end is that 50cm is to 80cm, the rotating shaft of described injector aerator and motor are surrounded by the glass reinforced plastic guard shield, and motor and inlet mouth are positioned at water surface top.
As the 5th kind of optimal technical scheme of the present invention, with being delivered in the aerobic aeration pond after the foul gas collection, remove contained repugnant substance by microbial process in the aeration tank.
As the 6th kind of optimal technical scheme of the present invention, injector aerator has simultaneously pumps the function that foul gas and aeration and plug-flow stir.
As the 7th kind of optimal technical scheme of the present invention, according to the foul smell amount that reality produces, open or close the jet aerator of pumping foul smell.
The beneficial effect that the present invention brings is:
1, realizes integral type art breading sewage, foul gas, had simultaneously sewage oxygenation+pump foul gas+processing foul gas+plug-flow to stir this tetrameric effect.
2, simplified to a great extent the technological design construction, the operation management is also more simple, and the Equipment Foundations investment of required usefulness also still less greatly reduces the Construction and operation cost, and is also lower to the requirement in place simultaneously, saved the space.
