Flow disturbance realizes the separation of denitrification sludge and bubble；Another kind is to pass through the mud air water that will be floated using three phase separation cover
After mixture is stopped, bubble voluntarily floats because light, and sludge voluntarily sinks because matter is close, to reach sludge, water and generation
Nitrogen three phase separation effect.Both methods has biggish defect.
Existing impeller plug-flow degasser, since mud air water is unidirectionally pushed during plug-flow, between three
Relative motion it is smaller, sludge and its bubble swept along can not generate relative motion, therefore only plug-flow is difficult to be isolated, even if
Impeller can cause extremely least a portion of sludge to deaerate the direct impact of gassiness sludge, but most of acting is used on plug-flow, energy
Consumption height and inefficiency.
Existing three-phase separating device has no dynamic since it is only the natural degassing after depending on gassiness Mud up-floating
Power inputs to break the stable state of the depressed conjunction of mud, and the effect is unsatisfactory.Usually there is thicker mud gas mixed layer gear in this cover
Portion's gassiness Mud up-floating stay to liquid level, causes cover internal mix layer more and more thicker, until completely losing the function of three phase separation
