high efficiency deep aerator is through two years of research and development of the company success of a new generation of aerator. Adopted a new structure design and principle of aeration, the optimization design of key parts are simulated experiment, it summarizes the surface aerator, the advantages and disadvantages of traditional jet aerator, make it has deep aeration, high utilization rate of oxygen, can greatly activated activated sludge respiration intensity, and good mixing function, low noise, easy installation, long service life, etc.

1. working principle

This machine is composed of submersible pump, jet, diffuser, air suction pipe and hose of five parts, as shown in the figure below. Based on traditional jet mechanism combines the advanced powder flow technology, adopts the jet aeration method.

   Running, the water pump impeller under the submersible motor drive at high speed, push the mud mixture into the jet formation of jet and produce negative pressure zone around the jet, the air through the suction suction jet nozzle negative pressure zone, the jet flow within the pipes, gas, water, mud mix, and through the diffusion of jet pipe jet kinetic energy into pressure energy after step by step into the diffuser. Within the bulk flow apparatus, gas, water and mud mixture mixed further, forcing gases continue to cut, grinding and emulsifying, ensure that the vast majority of oxygen dissolves in water. At the same time, under the action of jet fluid pressure, jet carrying oxygen molecules and the tiny bubbles and tilted downward from the nozzle to the scattered jet, diffusion, formation of water body and the impact of biochemical bottom sludge, mixing, from the bottom up gently to the surface of the water, tiny air bubbles in the water retention time average more than 30 seconds, make the oxygen in air was dissolved and absorbed adequately, improve the ability of oxygen transfer efficiency and oxygen filling.

This equipment can make the muddy water and air to produce high negative pressure in the jet device and strong turbulence, mixing, shearing, liquid film and gas film high-frequency oscillation, reduce greatly the diameter of bubble, the bubble number increase, increasing the specific surface area of bubbles, at the same time, it gets thin liquid film, can greatly reduce the mass transfer resistance, make the oxygen from the gas phase to the liquid phase better.

Jet in high speed process, under the action of the distributor in the high speed rotating, has the high angular velocity, the jet has strong penetrating power, the journey far the tiny air bubbles in water, enhance stirring, pushing flow and aerobic capacity.

2. High dissolved oxygen

Unique diffuser design and make the air inhaled and mud mixed evenly, bubble small and numerous, high rate of dissolved oxygen. Oxygen transfer efficiency is as high as 30%, 35% higher than that of traditional drum wind aeration.

3. Stir fully
  High-speed rotation of the gas, water, mud mixture (activated sludge) strong penetrating power, the oxygen transfer in water with high efficiency, and achieve good mixing effect, can ensure the activated sludge mixed evenly, keep active sludge in suspended state. At the same time, due to the push flow mixing effect is strong, and raise the utilization ratio of the volume of aeration Aeration refers to human biochemical aeration tank via the appropriate equipment into the air, in order to achieve the desired purpose. Good contact with water and air in exchange for gaseous substances and water treatment to remove the volatile substances in water, or gas escaping from the water, such as removing odor or water the harmful gas such as carbon dioxide and hydrogen sulfide; Or make the oxygen dissolved in the water, in order to increase the dissolved oxygen concentration, iron and manganese removal or promote aerobic microbial degradation of organic matter.

   Affect gas transfer rate between gas and liquid two phase factors are: the partial pressure of the gas in the gas phase and in the liquid phase concentration, temperature, and water two phase interface area composition, etc. Under the same temperature and partial pressure, the solubility of a gas in water is a constant (often referred to as equilibrium concentration); When the gas concentration is greater than the equilibrium concentration, escape from the water; Less than the equilibrium concentration, gas dissolved in the water. Reservoir or lake is often because of the algae and protozoans and plankton reproducing or animal and plant residues rot and stink. Smelly substance is often volatile organic compounds, fountains, multistage existes, multi-layer perforation plate and multi-layer drowning coke water aeration device, such as make water dispersed into thin film or droplet shape and remove it
   Groundwater containing hydrogen sulfide, carbon dioxide or sometimes too much iron, manganese, aeration process, is also available. Free carbon dioxide corrosive, high efficiency deep water alkalinity is go to Iraq aerator is through two years of research and development of the company the success of a new generation of aerator. Adopted a new structure design and principle of aeration, the optimization design of key parts are simulated experiment, it summarizes the surface aerator, the advantages and disadvantages of traditional jet aerator, make it has deep aeration, high utilization rate of oxygen, can greatly activated activated sludge respiration intensity, and good mixing function, low noise, easy installation, long service life, etc.

In the wastewater in the activated sludge process, the mixture must be dissolved oxygen aeration method supplies. The aeration aeration activated sludge process method can be divided into two categories: bubble aeration method and surface aeration method. The former is compressed air and gas equipment in the water through the pipe to the formation of tiny bubbles that float upwards through the water layer. The latter is an impeller or rotary brush vigorous agitation of the water, constantly with new interface and atmospheric exposure, bubble aeration method and surface except oxygen aeration method, also has the stirring effect, make the activated sludge maintain a state of suspension. About the aeration tank construction and equipment of the activated sludge process. In addition, bubble aeration method is also used in sewage treatment plant of grit chamber in order to flush sediment and prevent waste water from going rancid. Aeration is not only to make contact with the air oxygen filling liquid in the pool, and because of stirring liquid, accelerate the shift to a liquid oxygen in air, thereby complete oxygen filling purposes; In addition, aeration and prevent slurry from the pool sinking, organic matter and microbial strengthening in the pool, with the purpose of the dissolved oxygen contact , After aeration water by limestone bed filtration, make carbon dioxide into carbonate ions, at this time in bed to have a longer contact time. Dissolved iron and manganese in groundwater is generally low bicarbonate, and after contact with air to improve dissolved oxygen concentration due to lower free carbon dioxide concentration, which can be converted into precipitation. Iron, manganese content is generally not high, aerobic is not much, so the requirement for aeration is lower, and higher demands on contact time.
