Description
Technical field
The present invention relates to a kind of Landscape River aerator and aeration method.
Background technology
In recent years, due to river course, lake pollution increasingly severe, people are gradually from single urban sewage treatment gradually
Forward on the treatment range of the major concepts such as river and lake improvement.The administering method of river and lake is varied, but maximally effective
Also belong to biochemistry and add the processing method that ecologic facies combines.Biochemical treatment needs the maximum problem solved to enter in river course exactly
Row aeration, the principle of aeration is to be fully contacted water and air exchange gaseous material and remove volatile material in water, or
Make gas escape from water, as removed stink or the harmful substance such as titanium dioxide and hydrogen sulfide of water, or make oxygen incorporate
In water, to improve dissolved oxygen concentration, reach except ferrum, demanganization or promote aerobe degradation of organic substances；Additionally, aeration also has
In preventing river course, suspended substance sinks, the purpose that in reinforcement river course, Organic substance contacts with microorganism and dissolved oxygen, thus ensures river course
Interior microorganism, under conditions of having sufficient dissolved oxygen, carries out oxidation Decomposition to the Organic substance in sewage, purifies the water in river course, carries
High water quality.
Current aeration mode mainly has two kinds, and one is gas bubble aeration method, directly gas pressurized is entered poromerics,
Produce microbubble by the pore on poromerics, then allow microbubble incorporate water body；Another kind of method is surface aeration method, application
Impeller or the rotation brush vigorous agitation water surface, constantly with new interface and atmosphere；Gas bubble aeration method and surface aeration method are except oxygen supply
Outward, also there is stirring action, make activated sludge maintain suspended state.
But the aeration effect that conventional aerator is capable of is limited, aeration scope is less, thin in gas bubble aeration method
Hole is difficult to produce the bubble of micron level, and bubble easily mutually merges in water body and forms air pocket, thus overflows the water surface, gas
Specific surface area little, the pollutant easy blocking aeration holes such as the time of staying is short in water body, and oxygen supplement efficiency is low, the mud in water,
Thus reduce aeration efficiency, increase disposal costs；The dissolved oxygen content of surface aeration method is less, and aeration effect is the best, additionally exists
In rapid river course, aerator is not provided with fixed mount, and aerator is fixed insecure, and careless slightly being easy for makes aeration fill
Putting and washed away by current, if being arranged on above river course by aerator, then affecting aesthetics and the serviceability in river course.
Summary of the invention
Present invention aims to many deficiencies of prior art, it is provided that a kind of Landscape River aerator and aeration

2, in air intake duct, it is passed through pressure-air, high-pressure intake pipe is passed through water under high pressure, in oxygen intake pipe
Being passed through oxygen or ozone, the intersection at air intake duct, high-pressure intake pipe and oxygen intake pipe tentatively mixes, pressure-air
Producing with water under high pressure, oxygen and clash into, high pressure gas clashes into cutting water under high pressure, and water under high pressure is divided into tiny foam, smalls and oxygen
Gas contacts, and increases contact area, simultaneously the more oxygen amount of smalls portability, improves the aeration oxygen replenishing effect in river course；Pass through
Water under high pressure, pressure-air and oxygen are mixed by air and liquid mixer further, form gas and liquid mixture, by spiral deflector, and will
Water and gas mix homogeneously, make guarantee gas-liquid mixed effect, improves oxygen dissolution efficiency；By bubble generator to gas and liquid
Body carries out high speed rotating, produces substantial amounts of microbubble further, improves gas dissolved efficiency, it is to avoid the generation of air pocket, by micro-
Minute bubbles are transported in river course, increase its contacting with liquid phase, strengthen mass transfer in liquid phase speed, the oxygen being effectively improved in river course
Dissolution rate, thus promote the decomposition of bulk organic substance in water body, increase plankton and the activity of microorganism in water, repair
Ecological environment in water, increases water quality；
3, the ring-type aeration tube arranged and shower nozzle, expand aeration scope, improves aeration effect, it is to avoid concentrate on one
Local aeration, reduces the high pressure draught strong souring to activated sludge, reduces the probability that its machinery runs off；On shower nozzle
Arranging diaphragm, when jet, air-flow by diaphragm jack-up, causes air flow through the space ejection between diaphragm and shower nozzle, when not jet
Time, diaphragm covers on shower nozzle under the effect of self gravitation again, protects solarization air cap, it is to avoid the mud in the external world, particulate matter etc.
Pollutant blocking aeration hole, it is to avoid mud enters in aeration tube, reduces aeration rate；
4, the rotary blade arranged churns the surface, and constantly with new interface and atmosphere, promotes bottom water so that it is with table
Layer water alternates, thus plays the effect to bottom water oxygen supplement, is effectively improved water body environment so that it is the dissolved oxygen of surrounding water
