　　Submersible aeratorThe gearbox is made of gray cast iron. The transmission gear adopts two-stage gear transmissionAll hard toothed gears. Gear design shall comply with GB3480-83 standard. Each port of the reducer is sealed with a nitrile rubber O-ring, and the output shaft is equipped with a corrosion-resistant tungsten carbide hard alloy (WCCR) mechanical seal to ensure that the reducer leaks and has a service life of over 25000 hours. The output shaft of the reducer is made of stainless steel material. A life of 100000 hours in normal working condition.

The diving aeration tank adopts the theory of hydraulic propulsion ship propellerThrough computer optimization design, the overall impeller is made of high-strength and corrosion-resistant ZL108 aluminum alloy as a whole.

Each submersible aerator is equipped with support and hangersThe underwater part is made of 304 stainless steel square and round pipes (with a wall thickness of 5 millimeters), while the water part is made of 304 stainless steel material. Push a host flow guide frame to fix, with three rollers and box columns connected, and manually adjust the lifting equipment through stainless steel wire ropes and hangers. The inverter is working normally, and the tour guide should firmly stand on the bracket. The device can adjust the flow direction horizontally within a range of 120 ° by changing the position of the bolt holes on the index plate of the box type column. The clothes hanger can rotate 360 °, making it easy to install the host on the platform with ups and downs.

Performance and Structure

　　Submersible aeratorIt is a fully sealed designDiving. All components, including motors, impellers, etc., are capable of continuous operation. Using an efficient three-phase submersible motor, the motor shaft and rotor are dynamically balanced, and a rubber protective ring impeller is used to protect the mechanical seal made of fiber material.

Use energy-saving blades and self-cleaning functionExcellent hydraulic design ensures that mixing with smaller motor power can achieve the same effect. The diving aeration tank adopts sliding bracket insulation to prevent electrochemical corrosion, and the diving aeration machine is promoted for free. It can be easily removed for inspection or service without personnel entering the tank.

Installation bracket for the entire weight force of the submersible aeratorThe bracket can withstand all the thrust caused by the submersible aerator, eliminate the irregular flow force of the blades, and avoid vibration during operation. The lifting equipment is lightweight and installed on the working platform by the pool, including special hooks and twists for portable use.

The necessity in sewage treatment

Demonstration of the use of submersible aerators in sewage treatment

Submersible aerator in the aeration tank of the sewage treatment plant, aeration grit chamber, aeration and sludge mixed liquor mixed, and biochemical treatment or aquaculture pond oxygen sewage. Air flow is10-100 m3/h， The aeration rate is 0.35-8.20 kg/h of oxygen, and the motor power is 0.75-55 kW.

Due to the relatively late start of the domestic industry, there are few domestic suppliers specializing in the combination of system research and the development of applied products. Generally, there is no scientific research, systematic production, application, information feedback, and improvement mechanism. Therefore, the advantages of foreign material product quality.

There is still a considerable distance between system suppliers and design departments in terms of product connectivity technology, often resulting in products not being able to handle most things in their own way. For example:EPDM membrane is only used for urban sewage in developed countries. Nitrile silicon synthetic membrane (silicon) is recommended for oily sewage, chemical sewage, and amino acid lipid membrane (polyurethane). There is a single variety of membrane in China, and EPDM membrane is not qualified, but it is generally used in various sewage treatment projects. The operation and maintenance of partial identification of this product.

For example, in a small sewage treatment plant, the water level during the commissioning of the submersible aerator system had already submerged the aeration device, causing the diaphragm to rupture. Influenced by traditional concepts, the use of early surgeries in the same industry for aeration based replication has hindered the effective promotion and use of some superior aeration products. Overall, membrane aeration is the most popular choice for large-scale sewage treatment projects, especially in membrane aeration, which has achieved good results.

Aeration is an important process in aerobic biological treatment systems, which is generally achieved through the use of appropriate equipment such as artificial air biochemical aeration tanks to achieve the desired goals. Aeration not only allows the liquid to come into contact with the air in the oxidation tank, but also accelerates the transfer of oxygen to the liquid in the air due to the shaking of the liquid, thereby completing the oxygen oxidation processIn addition, ventilation and prevention of sinking of cell suspensions should be strengthened to enhance the contact between organic matter, microorganisms, and dissolved oxygen in the microbial pool to ensure sufficient dissolved oxygen conditions for the oxidation and decomposition of organic matter in sewage.

The aeration effect greatly affects the efficiency of biological treatment systems. Meanwhile, aeration is a process that consumes energy. In a typical aeration system, aeration is the entire system60% of energy consumption accounts for 80%. The quality of aeration devices not only affects the effectiveness of biochemical treatment, but also directly affects the treatment areas, investment, and operating costs.
