Description
Technical field
The present invention relates to technical field of sewage, specifically a kind of aeration decontamination apparatus.
Background technology
Water pollution problems is an environmental problem all over the world, and sewage disposal can be divided into thing by the Method means for using
Four kinds of logos, chemical method, physical-chemical process and bioanalysis.Bioanalysis is to decompose dirty using the metabolism of the microorganism in waste water
A kind of method of degradable organic matter in water, because having treating capacity big, small investment, the characteristics of economic and reliable, as current
A kind of world's method for treating water the most universal.Wherein, aerobe method face aeration efficiency it is low, aerator unstable properties
Etc. aspect problem.
Aeration refers to increasing water and air contact area with to methods such as Aeration in the water or mechanical agitations, is aerobic waste water
The middle process of biological treatment.Aeration is that water and air is fully contacted to exchange gaseous material and remove volatile materials in water removal
Method for treating water, or gas is escaped from water, such as remove the stink or carbon dioxide and hydrogen sulfide pernicious gas of water removal；Or make
Oxygen is dissolved in water, to improve dissolved oxygen concentration, reaches except iron, demanganization or promote the purpose of aerobe degradation of organic substances.
Aeration type is broadly divided into two classes：One class is blast aeration, is drawn in water using aerator diffuser plate or anemostat
Enter the aeration mode of bubble, more than the sewage disposal of general ethylene plant in this way；Another kind of is mechanical aeration, refers to and utilizes leaf
The apparatuses such as wheel introduce the aeration mode of bubble.
The form of micropore aeration pipe has various, and relatively conventional at present has two kinds：One kind is sintered by coarse porcelain or corundum etc.
Common aeration tube, this tube wall can produce many more small holes in sintering process, and it is mainly characterized by energy
Small bubble is enough produced, bubble diameter about 0.1mm~0.2mm, air-liquid contact area is big, and coefficient of oxygen utilization is high, typically can reach
20~25%；It has the disadvantage that atmospheric pressure lost is larger, easily blocks, and the air of feeding need to be fragile by filtration treatment, once damage
Bad, the utilization rate of oxygen will drastically decline, and service life is short, be difficult to change.
Another kind is tubular membrane micropore aeration pipe.The mounting means of this aeration tube is essentially the same with former, but its
The complex structure of itself, it is, as gas distribution pipe, air vent, cloth to be provided with tube wall by a pipe being made of ABS or UPVC
Tracheae periphery is covered with the diaphragm that synthetic rubber is made, and diaphragm is fixed on pipe by metal clamps.On synthetic rubber diaphragm
The eyelet with distribution is got with methods such as laser.During aeration, air by the passage entrance diaphragm on tube wall and tube wall it
Between, it is that diaphragm is heaved slightly in the presence of compressed air, eyelet opens, and reaches the purpose of gas distribution diffusion.Stop supply, air pressure
After disappearance, diaphragm sheet makes eyelet close automatically under elastic reaction, and due to the effect of hydraulic pressure, diaphragm compacting is on tube wall.
Therefore, sewage will not flow backwards and block eyelet.But because the opening diameter of this diaphragm directly influences coefficient of oxygen utilization, therefore,
Opening diameter should be appropriate.Opening diameter is excessive, and the utilization rate of oxygen is relatively low, and opening diameter is too small, and the utilization rate of oxygen is high, but resistance increases
Greatly.Rubber diaphragm is easily aging, easily tear, causes aerator to damage, and higher to the pressure requirements of aeration.
In consideration of it, be necessary to improve existing aerator, to solve the above problems.
The content of the invention
In order to make up the deficiencies in the prior art, the invention provides one kind aeration decontamination apparatus, water can be carried out secondary
