Treated for exporting sewage-treatment plant sewage, sewage-treatment plant include sewage treatment pot 1, are set to sewage treatment pot 1
Interior demarcation plate 2 and hollow stirrer axis 3, the middle part of demarcation plate 2 are equipped with through-hole 21, and hollow stirrer axis 3 runs through through-hole 21, are located at logical
Helical blade 31 is provided on hollow stirrer axis 3 at hole 21, the radius of spin of helical blade 31 is mutually fitted with the radius of through-hole 21
Match, sewage treatment pot 1 is divided into upper process chamber 11 and lower process chamber 12 by demarcation plate 2, and the worry of tubular is provided in lower process chamber 12
Cover 4, the top quartile of hollow stirrer axis 3 are arranged in upper process chamber 11 on the hollow stirrer axis 3 being located in upper process chamber 11
There are two rotating vane 32, two rotating vanes 32 are symmetricly set on the two sides of hollow stirrer axis 3, the lower part of hollow stirrer axis 3
Quartile is located on the hollow stirrer axis 3 considered in cover 4 that setting is there are three hollow jet stirring blade 33 in considering in cover 4, and three
Jet stirring blade 33 is evenly distributed on hollow stirrer axis 3, and three jet stirring blades 33 are connected with hollow stirrer axis 3
It is logical.When work, by the upper process chamber 11 of sewage input sewage treatment pot 1, the rotation of hollow stirrer axis 3 drives sewage input unit
Rotating vane 32 rotate, in upper process chamber 11 sewage and sludge be stirred, so that it sufficiently rolled, mixed, hollow stirrer
Axis 3, which rotates in the forward direction, drives helical blade 31 to rotate, and helical blade 31 passes through the gap between blade for the dirt in upper process chamber 11
Water brings 4 inside of worry cover in lower process chamber 12 into, and the rotation of hollow stirrer axis 3 drives jet stirring blade 33 to rotate, jet stirring
Blade 33 in lower process chamber 12 sewage and activated sludge be stirred, so that it sufficiently rolled, mixed, accelerate activated sludge in
Absorption and decomposition of the micropopulation to dirty Organic substance in water, to improve the efficiency of sewage purification, jet stirring blade 33 is stirred
While oxygen exposed by puff prot jet on jet stirring blade 33 make lower process chamber because of rotating in the forward direction for helical blade 31
Mixed liquor in 12 does not enter process chamber 11, and lower process chamber 12 is made to become aerobic room, and upper process chamber 11 becomes anoxic room,
Make to carry out denitrification in process chamber 11, lower process chamber 12 carries out nitrification, and realization is denitrification integrated, in hollow stirrer
When axis 3 reversely rotates, helical blade 31 is driven to reversely rotate, helical blade 31 passes through the gap between blade for lower process chamber 12
In mixed liquor bring into process chamber 11, flow back into the mixed liquor in lower process chamber 12 in process chamber 11, facilitate
Denitrifying progress optimizes denitrogenation, and can adjust the rotation speed of helical blade 31 by adjusting the revolving speed of hollow stirrer axis 3
Degree, to adjust the back-flow velocity of mixed liquor in lower process chamber 12.Considering cover 4 is tubular, and inside is equipped with filter membrane, for activity
Mud mixed liquid is filtered, and by the stirring jet of jet stirring blade 33, and can pass through the revolving speed of change hollow stirrer axis 3
With the gas pressure for entering hollow stirrer axis 3, and then change the mixing speed and whiff pressure of jet stirring blade 33, it can will be attached
Opsonigenous substance on the fenestra of filter membrane wash off, and the pollutant that filter membrane surface deposits is washed off, is prevented
Filter membrane blocking to prevent the flux of filter membrane from declining, and then extends the service life of filter membrane, improves the stability of effluent quality.
To enhance the filter effect to active sludge intermixture, keeps sewage treatment more thorough, further, consider 4 packet of cover
Outer worry cover 41 and interior worry cover 42 are included, interior to consider cover 42 positioned at the outer inside for considering cover 41, outer worry cover 41 is by the first inner plexiform layer 401 and is set to
The first outer plexiform layer 402 composition outside first inner plexiform layer 401, interior worry cover 42 is by the second inner plexiform layer 403 and is set to the second inner plexiform layer
The second outer plexiform layer 404 composition outside 403, the first inner plexiform layer 401, the first outer plexiform layer 402, the second inner plexiform layer 403, the second outer net
Layer 404 is cylindric reticular structure layer, for filter membrane or filtrate to be placed in the first inner plexiform layer 401 and the first outer plexiform layer
Between 402, between the second inner plexiform layer 403 and the second outer plexiform layer 404, it is conveniently replaceable filter membrane or filtrate, the first inner plexiform layer 401 and
It is provided with microfiltration membranes 421 between one outer plexiform layer 402, is provided with ultrafiltration membrane between the second inner plexiform layer 403 and the second outer plexiform layer 404
411, active sludge intermixture is filtered for the first time by microfiltration membranes 421 first, to be separated by filtration most activated sludge,
Enter in the filtrate chamber formed between interior worry cover 42 and outer worry cover 41 through the filtered mixed liquor of microfiltration membranes 421, considers cover 42 inside
And the outer jet stirring action for considering jet stirring blade 33 in the filtrate chamber formed between cover 41 weakens, and makes the mixing filtered for the first time
Liquid can consider inside cover 42 and it is outer consider stays for some time in the filtrate chamber that be formed between cover 41, to reinforce microorganism to having in sewage
The absorption and decomposition of machine object, then pass through the secondary filter of ultrafiltration membrane 411, sludge separation is more thorough, make pollutant removal more
Add clean, guarantee filter effect.
It is enhancing jet stirring blade 33 to the opsonigenous substance and the pollutant that is deposited of filter membrane surface in filter hole
