Description
Technical field
Reoxygenation machine technical field is the utility model is related to, specifically a kind of floating suction microbubble pure oxygen is empty to expose integrated reoxygenation
Machine.
Background technology
To accelerate to promote country《Water prevention and cure of pollution action plan》China's region and above city are built in " ten, water "
Into the requirement of area's black and odorous water：" by 2020, region and above completed region of the city black and odorous water were controlled within 10%, are arrived
2030, completed region of the city black and odorous water was totally eliminated " controlling target.In recent years, due to river course, lake pollution
It is increasingly severe, people gradually from single urban sewage treatment gradually go to river and lake administer etc. major concept improvement model
Gather around.The administering method of river and lake is varied, but most critical still needs to use restoration of the ecosystem to rebuild ecology
System, realize the ecological balance.The problem of maximum that restoration of the ecosystem needs to solve, is ensuring that river course oxygen is sufficient, aeration
Reoxygenation is that oxygen or air are filled with to water body to lift the dissolved oxygen levels in water body using artificial mechanical means, can be made
Water body is changed into oxygen-enriched by anoxic, and under oxygen-enriched environment, is suppressed anaerobe, is promoted the breeding of aerobic microbiological, so as to
It is set to carry out the materials such as aerobic decomposition, simultaneous oxidation NH3, FeS, H2S to the organic matter in water, diameter is at tens of μm at present
The application technology being aerated to less than several μm of the micro air bubbles for being referred to as microbubble in river regulation field is more noticeable,
It is primarily due to the system comprising multiple micro air bubbles in a liquid and the system phase for including single bubble with same volume
Than there is larger bubble surface area, and micro air bubble is also most long in the water medium holdup time.Therefore, micro air bubble
Gas dissolution characteristics, micro air bubble improve to characterization of adsorption of impurity in liquid etc., it is possible to increase material conveying effect.Micro- gas
Bubble technology obtains in the various industrial circles such as fish and shellfish cultivation, wastewater treatment, chemical reaction equipment, medical treatment, plant culture
Using.
In existing equipment：
（1）Plugflow aeration machine.Although bubbles volume caused by common plugflow aeration machine is big, bubble diameter is centimetre
Level, specific surface area is small, and bubble residence time is short, and dynamic efficiency is relatively low, and due to fixing steel-pipe pile, aerator is in the water surface
Under, repair inconvenience；
（2）Surface aeration machine.Directly to drive aial flow impeller using motor, by liquid from conduit through weather board to surrounding
Spray and form the water curtain an of thin slice (or drops), in flight way and air contact forms water droplet, hits liquid when falling
Face, liquid level produce sinuous flow and substantial amounts of bubble, make oxygen-containing increase in water.The water of bottom of pond can be sucted and be sent out by top, formed
One circulating water flow therefore the effect for having stirring concurrently, because the middle level of river regulation and bottom need also exist for dissolved oxygen and ensure microorganism
Aerobic breeding, therefore the structure of the inapplicable bed mud ecosystem；
（3）Air blower machine-micropore air dipelling disk aeration.Conveyed using the air blower with certain air quantity and pressure using connection
Pipeline, air is forced to be added in river course bottom by micropore air dipelling disk (or micropore diffuser), realizes that uniform aeration is oxygenated,
Because microporous aeration disc long-play easily blocks, and laying difficulty is big, and maintenance is inconvenient, therefore is not suitable for making on a large scale
With；
（4）Water carrying type aerator.Water carrying type aerator is pumped to top by the impeller for rotating liquid by high speed, from
Stomata projects form fountain landscape at a high speed, is oxygenated by transfer and reoxygenation convection current that oxygen is realized with air contact, but due to
Oxygen transfer efficiency is not high therefore is used in landscape design；
Dissolved oxygen levels are improved during river regulation in order to improve, strengthen removal ability of the river course to pollutional load,
Ensure the breeding of microorganism and the rapid build of the ecosystem simultaneously, " floating suction microbubble pure oxygen is empty for applicant's independent research
Expose integrated reoxygenation machine（Microbubble pure oxygen is empty to expose integrated aerator）" aerator.

Hit strongly, so as to produce milky micro air bubble, micro air bubble all increases much than common blister surface area and surface energy, table
The increase of face energy can strengthen surface oxidation reaction, improve the utilization rate of oxygen.Meanwhile this bubble considerably increases air and water
Contact area so that ratio, the life-span of bubble on the liquid interface of gas one shared by oxygen molecule both increase several orders of magnitude, therefore
It is trapped in that the time in water is longer, and dissolved oxygen concentration is higher；
（2）Controllability is strong, energy-saving.This equipment can be selected to be exposed using air aeration or oxygen with related request
Gas, while Inlet and outlet water control of flow and pressure air water ratio can be adjusted, realize energy-saving purpose；
（3）Integrated degree is high, easy to maintenance.Integration of equipments equipment compartment, pressure-stabilizing bin, workbench, part composition one
Body.When equipment, which breaks down, to be damaged, maintenance personal, which can enter, carries out maintenance activity above workbench, and due to using
Physical filtering measure, therefore compared with common aerator, have and be not easily blocked, run time is longer, impact resistance is stronger
The characteristics of；
（4）Economic benefit：The floating empty use for exposing integrated reoxygenation machine of suction microbubble pure oxygen can ensure river course dissolved oxygen
Abundance, and dissolved oxygen abundance is to administer the waters structure ecosystem, recovers the basic guarantee of the ecological balance.Economic effect caused by it
Benefit is that the improvement of river basins water quality can provide for the mankind and gathers place, public place of entertainment, scientific research and place of education, and has
Naturally the function of go sightseeing, travel, entertaining etc., it is often more important that when the original natural ecological environment of river regulation recovery is favourable
Value in lifting littoral land, and the pollutant degraded is advantageous to lift pollution emission reduction benefit；Ecology, social benefit：Dissolving
