The structural representation of the AOPs sewage treatment tower that Fig. 1 provides for the embodiment of the present invention; Fig. 2 is the structural representation of baffler in the AOPs sewage treatment tower shown in Fig. 1.
As depicted in figs. 1 and 2, a kind of AOPs sewage treatment tower that the present embodiment provides, comprising: tower body 1, first membrane district 3 of membrane district 2, second and liquid injection system 6, and liquid injection system 6 is for the internal spray liquid to tower body 1; First membrane district 2 and the second membrane district 3 are communicated with along the flow direction of mixed solution the inside being arranged on tower body 1 successively; First membrane district 2 and the second membrane district 3 are all for colliding and extrude the water droplet of mixed solution, and along the flow direction of mixed solution after the effect of multiple membrane districts, the surface-area of mixed solution water droplet increases gradually.
The mixed solution of indication in the present embodiment and following embodiment, can be liquid, solid or gas, mixing of materials can be the mixing of liquid liquid, liquid-solid mixing, gas-liquid mixed, etc.; Be sewage below with material, in sewage, add the material such as oxygenant, catalyzer is that example is described, sewage can select all kinds of need sewage to be processed, such as: the sewage of ultrahigh concentration, dyeing and printing sewage, electroplating sewerage, etc., in above-mentioned sewage, usually can containing more organic macromolecule pollution substance; Oxygenant is selected containing great amount of hydroxy group free basic group (OH, HO
2or H
2o
2) material.
It should be noted that, when the oxygenant used is for High energy water, use the material mixer that provides of the present embodiment to carry out mixed effect to sewage and High energy water better; So-called High energy water refers to: under artificial condition, overcome Henry Theorem the dissolves density value limit to oxygen family element, make the density value of the dissolved oxygen of unit (i.e. DO value) exceed the water containing high dissolved oxygen of the molecular state of more than saturation limit value; General, the DO value of High energy water is greater than 60mg/L.
It should be noted that: AOPs is abbreviation and the abbreviation of English AdvancedOxidationProcesses advanced oxidation processes.
The Main Function in the first membrane district 2 and the second membrane district 3 is that membrane makes water droplet through expanded surface area and collision and extruding mixed solution, and it can have multiple implementation, such as: multiple roller or multiple Ball-type packing, etc.; When selecting roller, mixed solution can pass through between adjacent two rollers, thus by these two roller compression, spherical water droplet becomes flake, thus realizes increasing the long-pending object of water drops surface.
First membrane district 2 is different with the action intensity of the second 3 pairs of mixed solution water droplets in membrane district, and along the flow direction of mixed solution, its reactive force is increased gradually, be in particular in, the surface-area of mixed solution water droplet increases gradually, laminar water droplet thickness reduces gradually, this just progressively can increase mixing of macromolecule contaminant and the materials such as oxygenant, catalyzer and flocculation agent, and the contact area between each material of mixed solution kind is increased, thus many kinds of substance is mixed more abundant.
The component realizing above-mentioned effect has a variety of selection, when all arranging multiple roller in the first membrane district 2 and the second membrane district 3, can realize above-mentioned functions by the diameter controlling distance between adjacent two rollers and roller; Distance between roller is less, larger to the action intensity of water droplet, and water drops surface is long-pending larger, thickness is thinner.
The AOPs sewage treatment tower that the present embodiment provides, sewage enters the inside of tower body 1, and the materials such as oxygenant, via liquid injection system 6, spray the inside into tower body 1, form mixed solution with sewage; Water droplet in mixed solution is after via the collision in the first membrane district 2 and the second membrane district 3 and squeezing action, water droplet can from drop-wise by membrane, be squeezed into flake, thus add the surface-area of water droplet, the organic macromolecule material be conducive in sewage contacts with materials such as oxygenants and mixes, mix more even, the chemical reaction in mixed solution more can be made more abundant, thus reach better wastewater purifying efficiency; And the material such as oxygenant, catalyzer is entered tower body 1 by injection, spraying can the larger kinetic energy such as oxygen supply agent, thus makes it fiercer with the collision of sewage molecule, contacts mixed effect better.
On the basis of above-described embodiment, particularly, be respectively arranged with the first filler and the second filler in the first membrane district 2 and the second membrane district 3, and the diameter of the first filler is greater than the diameter of the second filler.
The shape of the first filler and the second filler can have multiple choices, such as: spherical or square, etc.; The material of the first filler and the second filler also can have multiple choices, such as: titanium pearl filler, etc.
To fill the first filler in the first membrane district 2, illustrate: between multiple first filler, there is the space that mixed solution can be allowed to pass through, the quantity of the first filler 21 is more, just mixed solution can be divided into more less water droplets, thus make the mixing between many kinds of substance become the mixing of molecular level, to reach well-mixed object.
On the basis of above-described embodiment, particularly, also comprise the downstream that district of Xi Yan district 4, Xi Yan 4 is arranged on the second membrane district 3, and be communicated with the second membrane district 3; The inside in Xi Yan district 4 is provided with cyclone pipe 41 and multiple swirl flow nozzle 42, and multiple swirl flow nozzle 42 is all arranged on cyclone pipe 41, and multiple swirl flow nozzle 42 is all towards the same position atomizing of liquids of inside, Xi Yan district 4.
Chemical reaction or biological respinse is there is in sewage and oxygenant after the first membrane district 2 and the second membrane district 3 mix, can produce as solid matters such as salt, mud such as sodium-chlor, due to gravity and the swiftly flowing effect of mixed solution, be deposited to the bottom of tower body 1, therefore, Xi Yan district 4 is set bottom tower body 1, the solid matters such as the above-mentioned sodium-chlor of easy cleaning and mud; Because when sludge quantity is more, the flowing of mixed solution likely can be hindered, thus affect dirty water purification.
Multiple swirl flow nozzle 42 is all arranged on cyclone pipe 41, and is communicated with cyclone pipe 41; Cyclone pipe 41 is communicated with liquid injection system 6 or other waterworks, supplies water for giving swirl flow nozzle 42; Multiple swirl flow nozzle 42 is all towards the same position atomizing of liquids of inside, Xi Yan district 4, the solid matters such as the mud be deposited in Xi Yan district 4 can be blown afloat, thus in the AOPs sewage treatment tower working process that these solid matters are provided at the present embodiment, in Xi Yan district 4, all the time be in levitated state, avoid it to block the effluent cycle mouth be arranged in Xi Yan district 4.
