Description
Technical field
The present invention relates to technical field of sewage, is a kind of aeration decontamination apparatus specifically.
Background technology
Water pollution problems is an environmental problem all over the world, and sewage disposal can be divided into Physical, chemical method, physico-chemical processes and biological process four kinds by the Method means adopted.Biological process is that the metabolism of the microorganism utilized in waste water decomposes degradable a kind of organic method in sewage, because it is large to have treatment capacity, less investment, the feature of economic and reliable, becomes a kind of water treatment method that the world today is the most general.Wherein, the problem of the aspects such as it is low that aerobe method faces aeration efficiency, aerating apparatus unstable properties.
Aeration refers to and amasss with to the method such as Aeration in the water or mechanical agitation increase water and air contact surfaces, is the middle process of waste water aerobiont process.Aeration is the water treatment method that water and air fully contacts to exchange gaseous substance and remove volatile matter in water, or gas is overflowed from water, as removed stink or the obnoxious flavour such as carbonic acid gas and hydrogen sulfide of water; Or make oxygen dissolve in water, to improve dissolved oxygen concentration, reach deironing, demanganization or promote the object of aerobic microorganism degradation of organic substances.
Aeration type is divided into two classes substantially: a class is blast aeration, and adopt aerator diffuser plate or diffuser tube in water, introduce the aeration mode of bubble, the sewage disposal of general ethylene plant is adopted in this way more; Another kind of is mechanical aeration, refers to utilize the apparatuses such as impeller to introduce the aeration mode of bubble.
The form of micropore aeration pipe has multiple, comparatively common are two kinds at present: a kind of is the common aeration tube sintered by coarse porcelain or corundum etc., this tube wall can produce many more small holes in sintering process, its principal feature to produce small bubble, bubble diameter is about 0.1mm ~ 0.2mm, gas, liquid contact area are large, and coefficient of oxygen utilization is high, generally can reach 20 ~ 25%; Its shortcoming is that atmospheric pressure lost is comparatively large, easily blocks, and the air of feeding need through filtration treatment, and fragile, once damage, the utilization ratio of oxygen will sharply decline, and work-ing life is short, not easily changes.
Another kind is tubular membrane micropore aeration pipe.The mounting means of this aeration tube is substantially the same with front one, but the complex structure of himself, it be by a pipe made with ABS or UPVC as gas distribution pipe, tube wall has ventilation hole, gas distribution pipe periphery is covered with the diaphragm that synthetic rubber is made, and diaphragm is fixed on pipe by metal clamps.On synthetic rubber diaphragm with the methods such as laser get all with distribution eyelet.During aeration, air enters between diaphragm and tube wall by the ventilating pit on tube wall, and be that diaphragm is heaved slightly under compressed-air actuated effect, eyelet opens, and reaches the object of gas distribution diffusion.Stop air feed, after air pressure disappears, diaphragm originally makes eyelet automatically close under elastic contribution, and due to the effect of hydraulic pressure, diaphragm compacting is on tube wall.Therefore, sewage can not flow backwards and block eyelet.But because the opening diameter of this diaphragm directly has influence on coefficient of oxygen utilization, therefore, opening diameter should be suitable.Opening diameter is excessive, and the utilization ratio of oxygen is lower, and opening diameter is too small, and the utilization ratio of oxygen is high, but resistance increases.Rubber diaphragm is easily aging, easily tears, and causes aerator to damage, and higher to the pressure requirements of aeration.
Given this, be necessary to be improved existing aerating apparatus, to solve the problem.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of aeration decontamination apparatus, can carry out secondary aeration to water, aeration effect is better, and can filter the dirt in water, can increase water quality.
