The main function of the aerator in the aerobic treatment system is to supply oxygen to the water, so that the oxygen in the air can be effectively dissolved into the unsaturated water body to maintain the growth of microorganisms and biological oxidation. Today, the aeration head manufacturer Voss The special environmental protection tells about the several ways of aerobic tank tubular aerators.
1. Disc aerators, diaphragm aerators, aeration discs and aeration heads are all mushroom-shaped aerators
There are also many types of microporous aerators. Commonly used in sewage treatment are tubular aeration and disc aeration. There is not much difference between the two. They both have high oxygen utilization and low energy consumption in wastewater treatment. advantage. The membrane material on the surface of the microporous aerator adopts the anti-clogging surface layer designed by nanotechnology, so it can effectively prevent solid and biological solidification and crusting.
Generally speaking, when the design water depth is 6.5m and the effective water depth is below 6m, the microporous aerator is the most suitable choice.
In addition, the microporous aerator needs to be used in combination with the fan, so the compatibility of the two devices should be considered in the selection.
Diffused Aerators
Diffused aeration is also referred to as package-bed aeration, bottom aeration, or destratification system. No matter what they are called, they operate in the same manner. Typical systems have an air compressor that has a tube that that connects to a diffuser located at the bottom of the pond or lake. As air is forced down the tubing, the diffuser breaks it up into tiny bubbles that are released into the pond. The bubbling action of the air rising to the surface causing the water to de-stratify, meaning the poor, oxygen deprived water at the bottom of the package is mixed with the oxygen rich water above, causing noxious and harmful gases to be released into the atmosphere. At the surface, where the bubbles break, additional oxygen transfer is made adding to the overall oxygen content of the water.
2. Tubular aerators, elevating tubular aerators, and elevating aeration tubes are all tubular aerators
The rubber diaphragm aerator uses a perforated rubber diaphragm on the aeration keel. The diaphragm hole applied on the keel will automatically adjust the aperture according to the wind pressure. If the blower suddenly stops, the rubber diaphragm will The perforation will be closed immediately, thus avoiding the problem of sewage entering the aerator and causing damage. At the same time, in a sense, this structure is also similar to the pressure reducing valve of the blast aeration system, which can effectively avoid instantaneous high winds. Pressure damage to the aerator. However, the opening diameter of the diaphragm directly affects the utilization rate of oxygen. If the opening diameter is too large, the oxygen utilization rate is low. If the opening diameter is too small, the oxygen utilization rate is high, but the resistance increases. Therefore, the opening diameter should be appropriate. . Another problem is the aging of the rubber diaphragm. The high-heat and high-pressure air blown out by the blower is very likely to cause the aging of the rubber diaphragm. Therefore, it is necessary to choose an aging-resistant and high-strength colloid. , so as not to tear the diaphragm and cause damage to the aerator, which pushes up the purchase price of the rubber diaphragm aerator.
Therefore, in general, these two types of aerators have their own characteristics, and these two types of aerators have tubular and disc structures. As for which type of aerator to choose in an actual project, it is necessary to base on the actual situation. to compare options.
3. The difference between the disc diffuser aeration and the aeration disc tube
1. A single aeration tube is more expensive than aeration discs, so there are more aeration discs on the market now.
2. Advantages of aeration pipe, easy installation, less sediment deposition, large aeration area and low comprehensive cost.
