Molecule-refining oxygen-dissolution aeration device

Abstract

The invention discloses a molecule-refining oxygen-dissolution aeration device including a support, a housing fixedly arranged on the support, a center shaft arranged in the housing, a variable-screw-pitch helical blade assembly, and a gas-liquid mixing input pipe and a dissolved gas refined fluid output pipe which are connected at both ends of the center shaft at both ends of the housing respectively; the variable-screw-pitch helical blade assembly is arranged on the center shaft, both ends of the center shaft are each provided with a guide cone. With utilization of the action of mechanical cutting and hydraulic shearing, bubbles are broken and refined, gas is dissolved in a supersaturated manner, is maintained in water and is not easy to release, and at the same time, various suspended solids and macromolecular organic compounds dissolved in the water flowing through the device are cut and refined. The molecule-refining oxygen-dissolution aeration device can be directly used in aerobic biological treatment for sludge and wastewater treatment and polluted water body purification, and also can be used for aquaculture oxygenation, preparation of oxygen-enriched water, beverage aerating and other liquid gas-dissolution fields, and the refining mixing fields in a chemical production process.

Description

technical field [0001] The invention belongs to the field of subdivided molecules, and relates to a subdivided dissolved oxygen aeration device. Background technique [0002] Natural water has a certain self-purification ability, and the oxidation and decomposition of microorganisms is the main way for water self-purification. If the dissolved oxygen content in the water body is low, aerobic microorganisms will be inhibited, while anaerobic microorganisms will be active. When the total amount of pollutants entering the water body exceeds the self-purification capacity of the water body, the dissolved oxygen in the water body will be degraded and consumed by aerobic microorganisms, resulting in an anaerobic state of the water body, and the remaining pollutants will be decomposed into ammonia gas under the action of anaerobic microorganisms , methane, carbon dioxide, hydrogen sulfide and other gases that are toxic to aquatic organisms will eventually lead to the loss of the s...

AI Technical Summary

Problems solved by technology

The combination of organic matter and dissolved or granular natural organic matter in the environment leads to a large reduction in its free dissolved form. The interaction between pollutants in the water body makes them combine to form macromolecular groups or highly polar molecules. Pollutants and microorganisms The contact area is greatly reduced, and the cell membrane that is difficult to enter the organism is absorbed by microorganisms, resulting in a decrease in the biodegradability of pollutants

At this time, even if the concentration of dissolved oxygen in the water body is increased, the removal effect of pollutants is difficult to meet the requirements.
