Water treatment field, the aerating aerator being particularly applicable in sewage treatment process.
Background technique
Economic rapid development and living standard improves, so that water consumption increases with it, the discharge amount of sewage is also just therewith
It increases, the discharge amount of trade effluent, rural sewage and sanitary sewage is also increased by, due to protecting to environmental protection especially water environment
The understanding of shield is insufficient, and a large amount of sewage is unprocessed or processing is discharged into natural environment not up to standard, to river, lake,
Underground water causes pollution, the especially sewage of some industries discharge, containing chemicals, heavy metal, noxious material etc., to environment
It does great damage, habitat is damaged, people's health causes adverse effect, some will cause permanent potential threat.
Therefore, China formulates relevant laws and regulations, the dynamics to environmental protection is increased, wherein critically important work is controlling for water environment
Reason.
Therefore, China strictly limits all kinds of sewage, it is necessary to handle it is up to standard after can discharge.Sewage treatment
There are many method, but the mainstream processing method of trade effluent is using chemical method or physics, chemical combined method.Wherein using exposure
Gas method is an important process link of sewage aerobic biochemical treatment system, is important one of means.Because having big in sewage
Grain, bulk waste are measured, is bonded to each other, uniformity is very poor, and reaction is slow.The effect of aeration is filled in sewage into reactor
Air, using the oxygen in air, dissolved oxygen needed for microbial biochemical effect is provided, and keep micro- life in reactor sewage
Object, pollutant, dissolved oxygen three are sufficiently mixed, and for microbial degradation organic matter provide advantageous biochemical reaction condition.
There are many aeration method and equipment, generally can be divided into surface aeration, submersible jet aeration, heavy water aeration, blast aeration
Deng.But these methods most importantly play the role of aerating, the gas bubbles entered in water are larger, are easy the evolution water that floats
Face, blending is uneven, aerating low efficiency, can not play the role of broken dirt block on microcosmic.
Summary of the invention
To overcome the above disadvantages, it after study and is tested, it is anti-that the utility model provides a kind of aeration in sewage treatment
The center Ying Chi aerator.Realize that the utility model is adopted the technical scheme that: in a kind of aeration in sewage treatment reaction tank

Stomata is connected together with blade inner flow passage, and blade inner flow passage is connected by venthole with central axis connecting hole, transmission shaft with
Central axis connecting hole is connected, in order to which gas or liquid pass through.Support reinforcing plate is set between the blade.
The impeller of the utility model is stirring Special-purpose open type impeller, and blade is hollow, and gas or liquid can be by hollow
Blade enters in sewage to be processed.Due to the high-speed rotation of impeller, water and impeller form relative motion, in the end of blade
It will form negative pressuren zone, the absolute pressure of the negative pressuren zone is less than atmospheric pressure, and air can be inhaled into, enter in water, due to impeller
Rotation speed is fast, and a large amount of bubble will be incorporated and stir in sewage.Gas when speed of related movement reaches cavitation condition, in water
Bubble will be buried in oblivion, and form high-temperature and high-pressure conditions, and have microjet phenomenon, the solids polluted in water can with this condition by
It smashes, forms smaller size of object, and the oxygen largely mixed combines, and accelerates the speed of sewage treatment, improves treatment effect.
Furthermore some sewage disposal process need to add some chemical agents or flour, are purified water with playing
Effect.These chemical agents will generally be dissolved into liquid or suspension, be then added in sewage by pump.It is common to add
Entering method is to concentrate to be added by pipeline in the side of reaction tank.Medical fluid can be passed through blade passage by hollow shaft by the device
Rapidly, it is uniformly spiked into sewage, reduces mixing time, increase the uniformity of medical fluid.
The utility model is improved blending amount of the oxygen in sewage, is accelerated mixed by way of center impeller aeration
Speed is mixed, the small scale high temperature and pressure generated using cavitation effect is smashed the pollutant in water, accelerates reaction speed, is improved
Wastewater treatment efficiency.It is also possible to use medicament required for reacting is added by centre bore for the device, the mixed of medicament is improved
Speed and the uniformity are mixed, to improve wastewater treatment efficiency.
