The sewage treatment plant is an important component of the city, and most of the city's wastewater is treated here. There has always been a saying in the city that the use of submersible aerators is the main treatment method and a relatively reasonable treatment method. It uses submersible aerators, which are environmentally friendly equipment.

In fact, this type of aerator mainly performs mixed aeration to keep the activated sludge in good condition, and the activated sludge comes into contact with each other. In addition, it can also provide oxygen for aerobic microorganisms.

Aeration machine is a device used in sewage treatment plants. This is the main mechanical equipment in the aeration tank. Its main function is to play a good role in the culture medium. And this device also causes the medium to be insufficient in the aeration tank, resulting in a relatively large transport of the medium, which is of great significance for subsequent sewage treatment plants. Here, we introduce the form of aeration volume in a flow aerator.

Centrifugal aerators move through impellers, which can drive bubbles while rotating. Then, the untreated sewage is injected with bubbles, which undergo varying degrees of physical and chemical changes under the combined action of coagulants and flocculants, forming large suspended solids. The bubbles then generate buoyancy, slowly lifting the flocs up to the surface to form floating debris.

In today's industry, many tanks are used to process or transport materials or other auxiliary materials. When it comes to the treatment of materials in tanks, there is currently a submersible aerator that is very useful for mixing and processing mixed substances. Originally, aerators were mainly used as equipment in some sewage treatment sites, and their composition mainly includes submersible mixing pumps, impellers, internal pipelines, etc. Among them, the key equipment is a type of diffuser.

This is also the key reason why the aerator is called an aerator. With this type of diffuser equipment, combined with the original injection equipment, the effect of diffuser is achieved, forming the so-called aeration. As for the current submersible aerators, they are mainly used in sewage treatment tanks. Their operation is similar to that of mixing machinery, which uses a motor to start and then the high-speed operation of the impeller to mix the medium in the tank and push it into the jet injector. The high-speed rotation of the impeller around the jet injector causes the air pressure to be in a negative state. This effect causes a portion of the air to be drawn into the jet generator, and the motor and impeller are on the same axis, so the operation of the impeller and the transmission of the motor are relatively synchronized.

After purchasing the submersible centrifugal aerator equipment, we need to install it according to the instructions. There may be slight differences in installation for each different aerator, so don't think you can install it just by taking it over. If there are differences between the actual installation and the instructions, the malfunctions that may occur during operation may not be so optimistic. No matter what equipment we receive, the first thing we need to do is to skim through the manual to ensure the safety of both the machinery and ourselves!

Ecological treatment technology for landscape water

The lake water treatment technology mainly adopts centrifugal aerators andWater lifting aeratorSubmersible aerators are generally installed with a downward inclination or horizontal installation method, and there is no noise pollution during use. Their appearance design is beautiful and elegant, and they have no impact on the surrounding environment during use, nor do they change the landscape effect of the water body. Due to the small bubbles generated by submersible aerators, they have a slight buoyancy effect on water bodies. During the aeration process, suspended particles in the water can be floated to the surface, further purifying the water quality. Due to the easy adjustment of the installation angle of the aerator, different aeration angles such as horizontal, upward, and downward can be used according to the water depth of the pool, without stirring up the sediment in the river or pond. In this process, a concealed installation method is used, and only the scenic fountain, the slow water flow pushed by the submersible aerator, and the milky white bubble belt can be seen on the lake surface. The water lifting aerator adopts a beautiful appearance design, and the sprayed waterway has a beautiful shape. It is widely used for water purification and water landscape production in scenic water areas such as rivers, lakes, and parks.
Lake water treatment technology is used to purify the water quality of natural water bodies such as rivers, lakes, and reservoirs. It can effectively reduce pollution indicators such as organic pollutants and ammonia nitrogen in water bodies, remove black and odorous water, improve eutrophication of water bodies, and prevent algal blooms. It can eliminate black and odorous water, reduce organic pollutants and ammonia nitrogen in a short period of time, make the water clearer in appearance, eliminate odors, and gradually improve the self purification ability of the water in the subsequent cleaning process; Even under the condition that external pollution sources are not cut off, it can still reduce the impact of external pollution sources on water bodies through measures such as aeration and addition of microbial strains, and control the worsening of natural water pollution. Compared with traditional fixed sewage treatment methods, under the same treatment water volume conditions, its one-time investment is only 1/5 of that of fixed sewage treatment facilities; Moreover, it is not limited by spatial conditions and can increase the dissolved oxygen concentration of water, reduce pollution indicators such as organic matter and ammonia nitrogen in a relatively short period of time. It has the advantages of low cost, fast effectiveness, good results, convenient operation, and wide adaptability.
Centrifugal aeratorThe main function of oxygenation
1. Eliminate organic pollution and black odor
Under conditions of sufficient oxygen and abundant aerobic microorganisms, the organic pollution indicators COD and BOD significantly decrease, and the black and odorous phenomenon disappears. The toxic and harmful gases such as methane and hydrogen sulfide produced by the degradation of organic matter at the bottom of the lake are removed.
2. Reduce nutrient content in water bodies
After oxygenation, the anaerobic organic matter decomposition process at the bottom of the lake was inhibited, and the release of nitrogen and phosphorus nutrients at the bottom of the lake decreased. Meanwhile, the activity of aerobic microorganisms accelerates the inorganic process of the substrate. Phosphorus can combine with calcium in water to form insoluble compounds, which settle at the bottom of the lake and are removed from the water.
3. Eliminate algal blooms
The convective exchange conditions caused by water aeration make it difficult for surface blue-green algae blooms to form; Algae in surface water are transferred to the bottom of the lake or lower water layer, and due to changes in lighting conditions, it is difficult to maintain growth and inhibit algal reproduction.
4. Improve water color and transparency
Various inorganic and organic suspended solids, live phytoplankton and dead debris, large aquatic plant debris, decomposed organic debris, etc. in polluted water bodies are the main substances that affect water color and transparency. After aeration and oxygenation of the water body, it effectively inhibits excessive algal growth, reduces organic matter in the water, significantly improves water transparency, and improves water color.
5. Reduce endogenous pollution in sediment
After the water body is oxygenated, the oxygen content in the surface layer of the lake sediment increases, and aerobic microbial activity becomes stronger. Through the metabolic process of microorganisms, the degradation of organic pollutants in the sediment is promoted, gradually forming an inorganic sediment cover layer and blocking endogenous pollution.

220VBefore starting the centrifugal aerator, it should be regularly inspected to ensure that the equipment operates safely and effectively.

1. Before operating the centrifugal aerator, use a 0-500V megohmmeter to check the insulation resistance of the motor stator winding. The minimum resistance to ground should not be less than 50 ohms.

2. The power supply voltage must be within the rated voltage range of+/-5% as indicated on the nameplate. The increase in power supply voltage is not allowed to exceed 10% of the rated voltage. If the power supply is used far away from the centrifugal aerator, the cross-sectional area of the cable should be appropriately bold, and the joints should be as few as possible, otherwise the voltage will drop too much. The joints should be sealed and waterproof.

3. The cable grounding is a general green wire, and in order to ensure safety, it must be firmly 50mm longer than the ground. It is also necessary to ensure that the aerator is properly grounded.

4. Motor cables or motor cables shall be YC YCW.

5. Heat switch to starter. Thermal switches are connected to the stator and are usually closed.

6. The leakage protection line should be the correct access control circuit; The oil chamber leakage protection device can detect whether there is water in the oil chamber. If the oil contains 30% water, an alarm signal will be issued. Changes within 7 days after the alarm. If the oil and sensor alarm, please contact my secretary.

7. To avoid water in the mixer, it is necessary to check whether the cable inlet sealing sleeve and gasket, as well as the diameter of the cable, are not damaged with the cable sheath.

8. Please note that the starting current may exceed 3 to 5 times the rated current to ensure that the fuse or circuit breaker has an appropriate ampere value. The rated current and starting current, fuse current intensity, and cable must be selected according to relevant technical standards and procedures.

9. Overload protection (motor protection circuit breaker) should be set to 1.1 times the rated nameplate current setpoint of the motor.
