Description
Technical field
The utility model relates to a kind of air-diffuser, particularly a kind of can guarantee aerobic microbiological under the condition of sufficient dissolved oxygen is arranged to sewage in organic oxygenolysis, improve the aerator of sewage biochemical treatment effect.
Background technology
At present, in sewage biochemical treatment engineering, the aerating apparatus of widespread use mainly contains pottery (corundum) aerator and rubber diaphragm aerator.
The characteristics of pottery (corundum) aerator are with corundum aeration cap and ABS plate (acrylonitrile/butadiene/styrene multipolymer plate) merging, to process pottery (corundum) aerator of one.As shown in Figure 1, it is that corundum aeration cap, corundum plate 4 are the ABS plate that this aerator major parts has ceramic head 3 (corundum matter), also is called air distribution plate, ventilation screw rod 6.Pottery (corundum) corundum ceramic head that aerator adopted is to be processed by silicon oxide, alumina high temperature sintering, and the cloth gas-bearing formation is more crisp; Surface irregularity, ceramic head is thicker simultaneously, and air passageways is long; And be mostly sharp-pointed and coarse duct, so its surface very easily grows mikrobe, stopped up by impurity in the air easily; Clean the aerator after 2-3 time, result of use is poorer.
The disadvantage of pottery (corundum) aerator is that their hole can produce biofouling.When aerator had just brought into operation, the pressure-losses was more stable, but after running to the certain period, and loss of head can sharply increase suddenly---the reason of Here it is biofouling.Not only can reduce the work-ing life of gas blower, and current consumption increases.
According to the main flow viewpoint, pottery (corundum) aerator is forever to move, and can not damage.Because the production process relative complex of pottery (corundum) aerator in former many operations of expecting finished product, has only and strictly carries out each item process system, holds each and closes, and just can prepare qualified pottery (corundum) product.If because the carelessness of some critical process, just can bring hidden danger of quality to product.From sample, be difficult to judge the quality quality of a pottery (corundum) aerator, above-mentioned hidden danger of quality will cause pottery (corundum) aerator after date when using a section, and some thing comes off in the hole, and it is big that hole becomes, and oxygen transfer efficiency descends, and increases energy consumption.
The rubber diaphragm aerator, as shown in Figure 2, comprise gland A7, rubber air distribution plate 8, supporting plate A9 and chassis A10.Because its air distribution plate has adopted the vulcanized rubber diaphragm, the gathered micropore of inflation of its surface, along with the increase of working time can cause rubber diaphragm aging, play drum, finally cause diaphragm to be torn, have influence on the works better of whole aerating system.If the content of cl ions or other chemical cleaners is more in the sewage, also can accelerate the sclerosis of vulcanized rubber diaphragm-operated, shorten its work-ing life; So generally speaking, the work-ing life of rubber diaphragm aerator is shorter.
Summary of the invention
The purpose of the utility model is: the shortcoming that oxygen transfer efficiency is low and work-ing life is short that overcomes the prior art aerator; Provide a kind of sewage of can realizing fully to contact with air, guarantee aerobic microbiological under the condition of sufficient dissolved oxygen is arranged to sewage in organic oxygenolysis, efficiently improve the air-diffuser of a kind of sewage aerobic biological treatment of sewage biochemical treatment effect.
The utility model is achieved through following technical scheme:
A kind of do not have obstruction, a non-maintaining sewage biochemical treatment aerator; Comprise gland B, air distribution plate, supporting plate B and conical chassis B; It is characterized in that said air distribution plate is the composite polrvinyl chloride air distribution plate, the surface of composite polrvinyl chloride air distribution plate is provided with solarization air cap; Below supporting plate B, be provided with one way stop peturn valve above the B of chassis, the conical lower section of B is provided with the saddle seat that is used for fixing aerator, connecting tube on the chassis.
Described one way stop peturn valve is the one way stop peturn valve of sealing.
The beneficial effect of the utility model is, provides that a kind of oxygen supply rate is high, the air-diffuser of the sewage aerobic biological treatment that needs to clean never, be prone to install.The utlity model has superior corrosion resistance, oxidation-resistance, and in light weight, intensity is high, do not stop up, be convenient to install; Can reach its work-ing life more than 10 years; Energy-conserving and environment-protective more, but compare save energy 25%～30% with conventional art.Especially for the transformation aspect of old system, can reduce the difficulty of transformation and the maintenance cost in later stage greatly.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The utility model adopts conventional process for producing and conventional starting material to make.
" aeration " is meant an important process process in the sewage aerobic biological treatment system; Provide by gas blower and to purify air; Send into through tubing system in the aerator that is covered with solarization air cap of biological tank bottom, aerator becomes small bubble to be diffused in the sewage air dispersion.
The utility model does not have obstruction, non-maintaining sewage biochemical treatment aerator, is circle, be a kind of efficient, energy-conservation, do not have stop up, non-maintaining aerating apparatus.As shown in Figure 3, composite PVC air distribution plate 12 be arranged on supporting plate B13 above, the surface of composite PVC air distribution plate 12 is covered with solarization air cap, gland B11 is used for fixing composite PVC air distribution plate 12, is provided with chassis B14 below the supporting plate B13, chassis B14 is conical; Below supporting plate B13, above the B14 of chassis, the ingress that purifies air is provided with one way stop peturn valve 15, the conical bottom of B14 is provided with the saddle seat 16 that is used for fixing aerator, connecting tube on the chassis.
At first get into aerator one way stop peturn valve 15 by purifying air of providing of gas blower through gas distributionbranch pipe; Enter into the gap of composite PVC air distribution plate 12 and supporting plate B13 through one way stop peturn valve 15; After gas overcame various resistances, the solarization air cap from composite PVC air distribution plate 12 was diffused into the sewage, through effective cutting air; Make it form micro-bubble, improved to maximum efficiency the oxygenation rate.Through the accurate constant pressure arrangement that calculates configuration; Can make the bubble uniform distribution, owing under the constant pressure arrangement effect, the bubble uniform distribution is dissolved in the sewage; For the biochemical reaction of mikrobe provides sufficient dissolved oxygen; Make active sludge be in suspended state, thereby guaranteed that active sludge makes full use of the dissolved oxygen decomposing organic matter, and improved the effect of sewage biochemical treatment.Owing to installed and used the one way stop peturn valve 15 of sealing fully in the ingress that purifies air, so effectively prevented the refluence of sewage.
Because the composite PVC air distribution plate 12 of the utility model has adopted composite PVC (SE) material, avoided the phenomenon that similar rubber is aging, play drum, also overcome shortcomings such as easy obstruction, pressure is high, work-ing life is short simultaneously.
The specification of the utility model aerator is φ 150, φ 21 and φ 260, also can set concrete size according to the actual requirements.
The utility model does not have obstruction, non-maintaining sewage biochemical treatment aerator, is applicable to that municipal wastewater treatment plant is newly-built, enlarging and for the transformation of old aeration tank, but the also intermittent operation of improved aeration tank.
