Description
Technical field
The present invention relates to sewage treatment area, especially a kind of aeration unit and the aerator containing it.
Background technology
In purification of waste water field, approximately 80% sewage treatment plant adopts activated sludge process. In the sewage treatment plant of employing activated sludge process, " aeration " is must indispensable process procedure. Along with the raising day by day of environmental requirement, long period continuously operation has become very necessary problem for sewage treatment plant, and this is because the difficulty that sewage treatment plant's shutdown is overhauled, overhaul in even emptying pond is increasing. Analyze from technical standpoint, if aerating system did not lose efficacy, sewage treatment plant need to shut down the probability of maintenance can be very low. So, in the life-span of improving aerating system, extend exactly sewage treatment plant's cycle of operation continuously. Meanwhile, the electricity charge are main running costs of sewage treatment plant. Compare with developed country, the specific energy consumption of wastewater treatment in China factory has reduced space by a relatively large margin, wherein aeration power consumption accounts for 50% left and right of the total power consumption of sewage treatment plant, reduce the power consumption of aeration process, not only can improve the operating profit of sewage treatment plant, can also shorten enterprise of China aspect energy consumption with the gap of international most advanced level.
Blast aeration is the aeration form being most widely used at present. In blast aeration system, micro-hole aerator is current comparatively conventional aerator. According to version, micro-hole aerator can be divided into three kinds: board-like, and disc type and tubular type. Its operation principle is: air blast is transported to air to be arranged in water-bed micro-hole aerator by pipeline, and through the aperture on micro-hole aerator, air is cut into many minute bubbles and is distributed in water, reaches the object to the bacterium oxygen supply in sewage.
Further division is done in the aspects such as the state from the moulding in hole and work, and micro-hole aerator can be divided into two kinds: boring aeration device and can closed pore aerator. So-called boring aeration device, is exactly no matter whether air blast supplies gas, and its hole is all opened wide, as corundum-aerator; What is called can closed pore aerator, and exactly in the time that air blast stops supplying gas, hole can be closed, and after air blast is supplied gas, pressure rise is during to certain index, hole can be opened, as rubber membrane type micro-hole aerator.
The main advantage of boring aeration device has: 1) go out atmidometer little, power consumption is just little; 2) material is selected widely, is easier to find longer material of life-span, is also easier to realize the aperture that gathers and does not but reduce the object of bulk strength, is namely easier to the problem of avoiding damaged. The shortcoming of boring aeration device maximum is: in the time stopping supplying gas, sewage can pour in down a chimney and enters in aerator; Sometimes,, in the time that gas pushing quantity is not enough, also has a small amount of backing up of sewage and enter in aerator. The impact of pouring in down a chimney the most directly of sewage is exactly the micropore on blocking aeration device, and then causes the inefficacy of aerator. If check valve is not installed, sewage also can further pour in down a chimney in main pipeline.
Compare with boring aeration device, rubber membrane type micro-hole aerator has substantially solved the problem of pouring in down a chimney in principle, in the time of stuffiness, aperture on rubber diaphragm can be closed, the good lock ring of rubber membrane sector-meeting is on stay pipe, aerator has obtained good sealing, and sewage can not enter in aerator. But because the reason of material and structure, the shortcoming of rubber membrane type micro-hole aerator also clearly, mainly contains: 1) need extra power consumption to expand diaphragm and expansion aperture, increased the power consumption of whole aeration process; 2) rubber diaphragm is easily aging, and diaphragm and aperture are all for a long time in expansion state, along with aging aggravation, the elasticity of rubber diaphragm can decline, even can lose bullet, sealing effectiveness also just goes from bad to worse, when realizing because of undershrinking while sealing completely, sewage will penetrate between diaphragm and stay pipe and in the chamber of aerator, once sewage enters, started the process of vicious circle, mud in sewage can be stayed between diaphragm and stay pipe, and the damaged speed of diaphragm also can be accelerated thereupon; 3) aperture that gathers on rubber diaphragm, has reduced the intensity of rubber diaphragm, has strengthened the probability of rubber membrane breakage; 4) in the time there is breakage in arbitrary rubber diaphragm, first be the difference forming on atmidometer, a large amount of gas can pass through from the little damaged mouth of resistance, damaged mouthful can be stretched again, simultaneously, because go out the problem of atmidometer, adjacent with damaged aerator, can start to reduce aeration with other aerator of its intercommunication even cannot aeration; In addition, sewage also can pour in down a chimney from breakage, and the sewage pouring in down a chimney can also enter into other aerator that be adjacent, can intercommunication, until this group aerator is entirely ineffective, if do not close the valve of this group, air blast carries the gas of coming substantially all from damaged mouthful invalid having passed through.
In sum, develop a kind of novel aerator, make its advantage that should retain rubber membrane type and punched-type micro-hole aerator, overcome again the deficiency of the two, just become the urgent need in purification of waste water field.

In the present embodiment, be opened to from ventilation the closed angle of stopping the supple of gas or steam, the effect of elastomer and existing rubber membrane is identical. But in the present embodiment, the power of open and close is not exclusively from rubber itself, but mainly depend on the active force that air pressure and hydraulic pressure produce. In addition, elastomer is thicker than rubber membrane far away, also as rubber membrane, does not open a lot of apertures above it simultaneously, and intensity easily ensures; And in the parcel of elastomer in housing, Long Term Contact be air, aging speed can slow down; In addition the deflection of elastomer under air pressure or hydraulic pressure is very little. So elastomer can work long hours, can not be torn.
In the present embodiment, the effect of cutting apart is worked to gas in the hole on housing, and hole keeps long opening, and the kind of available like this material is a lot, and good material can reduce and atmidometer. Meanwhile, hole also can be opened littlely and be more, to improve the utilization rate of oxygen. And the resistance of giving vent to anger reduces and coefficient of oxygen utilization raising can reduce unit power consumption. In addition, the long service life of good material, can extend the cycle of operation.
The aerator of the present embodiment can be installed according to the ordinary skill in the art, provides a kind of mounting means for reference at this. In the time that tubular type aerator is installed, the air inlet end cap of tubular type aerator is connected on the main pipeline at the bottom of pond by pipe fitting, plays the effect of fixing and air inlet, locking end cap fixes on the ground by support, at the bottom of whole aerator is placed horizontally to pond, and at the bottom of pond, keep certain spacing. After installation, air is provided to this aerator by feeder, air forms many tiny bubbles and is distributed in sewage after aerator, thereby oxygen is provided to the aerobic bacteria of disposing of sewage.
