Abstract
The present invention relates to a kind of sewage treatment blast aerator, which is mainly made of water inlet pipe, air blast air inlet pipe, jet stream aspirator, decline diffuser, rotational flow aeration device.The blast aerator, mainly waste water realize the mixing of waste water and air via water inlet pipe and the air of air blast air inlet pipe, are delivered to decline diffuser via jet stream aspirator, are mixed by rotational flow aeration device with the waste water of reactor content.Compared with prior art, advantage of the present invention includes: the strong mixing that the present apparatus can realize gas and water, mud three-phase, substantially increases the dynamic efficiency of aerobic reaction, and oxygen utilization efficiency may be up to 4kgO2/ degree electricity.
Description
Technical field
The present invention relates to a kind of sewage treatment blast aerators, especially for aerobic activated sludge process water process work
Skill.
Background technique
Aerobic Process for Treatment is to handle the common method of sewage, mainly in the presence of microorganism, in suitable carbon-nitrogen ratio, aqueous
Under the conditions of rate and oxygen etc., by organic matter degradation, it is converted to the biochemical process of humus sample substance.Aerobic treatment technology is because can be real
The minimizing of existing solid waste, innoxious and recycling processing target, it is considered to be organic solid castoff processing has
Efficacious prescriptions method.
Aerating system is the important component of Biological Contact Oxidation Process, can be by the biomembrane activity on filler
The biological treatment efficiency of system is directly influenced, and because the utilization rate difference of oxygen determines the power consumption of biochemistry pool.
Fixed aerator is generally fixed to biochemistry pool bottom of pond, and major advantage is that structure is simple, low in cost.Mainly
The disadvantage is that it is in supersaturated oxygenation state always to the waters of the water surface at the top of aerator, and other waters are then in unsaturation and fill
Oxygen condition, oxygen concentration gradient are unevenly distributed, and coefficient of oxygen utilization is relatively low, are easy to produce part " slough ".
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of sewage treatments to rouse
Wind aerator.
A kind of sewage treatment blast aerator, by water inlet pipe 1, air blast air inlet pipe 2, jet stream aspirator 3, diffuser 4
It is formed with rotational flow aeration device 5, in which: the top of jet stream aspirator 3 is passed through water inlet pipe 1, and side is passed through air blast air inlet pipe 2, diffusion
The input terminal of the output end connection rotational flow aeration device 5 of pipe 4, the output end of rotational flow aeration device 5 connect sewage-treating reactor, waste water
The mixing for realizing waste water and air in jet stream aspirator 3 via the air of water inlet pipe 1 and air blast air inlet pipe 2, takes out via jet stream
Haustorium 3 is delivered to diffuser 4, then is mixed by rotational flow aeration device 5 with the waste water in sewage-treating reactor.
In the present invention, the oxygen utilization efficiency of the rotational flow aeration device 5 is up to 4kgO2It is more than/degree electricity.
In the present invention, jet stream aspirator 3 uses the positive jet flow aspirator of air blast.
Working principle of the present invention is as follows:
It is made of the positive jet flow aspirator of air blast, diffuser, rotational flow aeration device.The blast aerator, mainly waste water
The mixing that waste water and air are realized via the positive jet flow aspirator of air blast, is delivered to rotational flow aeration device via diffuser, by eddy flow
Aerator is delivered to inside sewage-treating reactor.
Compared with prior art, advantage of the present invention includes: that the present apparatus can realize that gas and water, mud three-phase strength mix, and is mentioned significantly
High the efficient power efficiency of aerobic reaction, oxygen utilization efficiency may be up to 4kgO2/ degree electricity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of sewage treatment blast aerator of the present invention；
Fig. 1 label: 1 is jet stream aspirator, and 2 be diffuser, and 3 be rotational flow aeration device, and 4 be decline diffuser, and 5 be spiral-flow aeration
Device.
Specific embodiment
A kind of processing of the high-concentration hardly-degradable organic chemical waste water of embodiment 1
As shown in Figure 1, the present apparatus is by jet stream aspirator 1, diffuser 2, rotational flow aeration device 3, decline diffuser 4 and rotational flow aeration device
5 compositions, in which: jet stream aspirator 1 uses the positive jet flow aspirator of air blast.The top of jet stream aspirator 3 is passed through water inlet pipe 1, and one
Side is passed through air blast air inlet pipe 2, waste water via the air of water inlet pipe 1 and air blast air inlet pipe 2 is realized in jet stream aspirator 3 waste water and
The mixing of air, via the input terminal of the output end connection diffuser 4 of jet stream aspirator 3, the output end of diffuser 4 connects eddy flow
The input terminal of aerator 5, the output end of rotational flow aeration device 5 connect sewage-treating reactor, waste water via water inlet pipe 1 and air blast into
The air of tracheae 2 realizes the mixing of waste water and air in jet stream aspirator 3, is delivered to diffuser via jet stream aspirator 3
4, then mixed by rotational flow aeration device 5 with the waste water in sewage-treating reactor.It is exposed using the sewage treatment of the invention with air blast
Device of air handles high-concentration hardly-degradable organic chemical waste water, waste water via the air of water inlet pipe and air blast air inlet pipe realize waste water with
The mixing of air is delivered to decline diffuser via jet stream aspirator, mixed by rotational flow aeration device and the waste water of reactor content
It closes, through overtesting, dissolved oxygen concentration reaches energy consumption under the square one of 5.0 ~ 6.0 mg/L and substantially reduces, it can be achieved that oxygen utilization
Efficiency is up to 4.2 kgO2/ degree electricity.The present apparatus can realize that gas and water, mud three-phase strength mix, and substantially increase the effect of aerobic reaction
Rate dynamic efficiency.
