The contact surface of sewage, water depth effect time of contact, coefficient of oxygen utilization influence gas consumption and Air Bubble Size, therefore form " electric power energy consumption-
The closed loop that the several factors of the fine and closely woven degree-sewage deep-kinetic energy demand of stomata " condition each other.For example, one cube of air is got to the bottom
(4-6 meters general) to be equal in the water-bed sewage for arranging one cube, range ability of the bubble in sewage only has 4-6 meters, and oxygen utilizes
For rate about 10% or so, the coefficient of oxygen utilization with the sewage of turbidity directly determines that expending much energy gets to the bottom for air.By
The reason of quick-fried method structure designs the bottom of in, if increasing oxygen contact surface using gas vent is reduced to promote coefficient of oxygen utilization, mesh
Deposit in smaller sewage easily results in blockage, and equipment is placed in sewage bottom, must stop production and cut off the water to be tieed up after blocking
Repair replacement.
It is big that the aeration of the above quick-fried method of traditional bottom is uneven, sludge is easy deposition, air inlet demand, causes equipment energy consumption big；It is right
In factory be all very big loss.
