Abstract:
Control over the wastewater purification can be achieved through controlling delivery of gas-dispersion return sludge solely to an aerobic reaction vessel. The gas-dispersion return sludge is created using pure oxygen or oxygen containing trace amounts of ozone as a reactive gas, which is blended with return sludge to create a mixture of gas and liquid, which is pressurized with an atomizer pump, and then at a pressure of not more than approximately 5.5 MPa, the mixture is passed through an atomizer which uses cavitation or ultrasound at a frequency of less than 12,000 KHz to instantly render the reactive gas in the mixture to an ultra-fine bubble state. A portion of the gas is placed into a dissolved state, reaching a state of supersaturation with a high DO value of 20-40 mg/l, and causing the remaining ultra-fine bubbles to create an ultra-fine bubble condition.

Claim (Index 1):
A system for wastewater treatment using selective gas-dispersion return sludge delivery, comprising:\n a sedimentation vessel into which wastewater comprising inorganic solids and solid organic materials is pumped and in which at least some of the inorganic solids settles from the wastewater; an adjustment vessel into which the wastewater from the sedimentation vessel is pumped and which comprises anaerobic organisms that solubilize at least some of the solid organic materials within the wastewater; one or more aerobic reaction vessels into which the wastewater from the adjustment vessel is pumped and in which the wastewater pumped from the adjustment vessel mixes with a gas-dispersion return sludge to form a mixed liquor, the gas-dispersion return sludge comprising at least one reactive gas a portion of which is dissolved and a portion of which is in a state of ultra-fine bubbles, the gas-dispersion return sludge further comprising aerobic microorganisms that immobilize the solubilized organic materials within the mixed liquor as activated sludge using the at least one dissolved reactive gas, wherein at least some of the ultra-fine bubbles dissolve within the mixed liquor upon a consumption of the dissolved portion of the reactive gases by the aerobic microorganisms; a sludge sedimentation vessel into which the mixed liquor is pumped from the one or more aerobic reaction vessels and in which the mixed liquor is separated into a supernatant and the activated sludge; a sludge storage vessel into which the activated sludge from the sludge sedimentation vessel is pumped, wherein at least some of the activated sludge from the sludge storage vessel is pumped to a line atomizer as a return sludge; and a gas generator configured to generate the at least one reactive gas; and the line atomizer configured to form the gas-dispersion return sludge by rendering at least a portion of the at least one reactive gas generated by the gas generator into the ultra-fine bubbles within the return sludge, wherein a portion of the ultra-fine bubbles dissolves within the return sludge, the line atomizer further configured to pump the gas-dispersion return sludge solely into the one or more aerobic reaction vessels.
