INTRODUCTION

The submersible motor, as the power core, has excellent sealing and waterproof performance and can operate stably underwater, providing strong power for the entire equipment. The impeller adopts a unique design, and its shape and angle have been carefully optimized so that when it rotates, it can not only generate a powerful mixing force to promote the full mixing of substances in sewage but also effectively enhance the up-and-down circulation of the water flow and improve the fluidity of the water body. The aeration device is responsible for evenly distributing air into the water to increase the dissolved oxygen content in the water and create favorable conditions for the growth and reproduction of microorganisms. The draft tube plays a role in guiding and constraining the water flow, further enhancing the effects of mixing and aeration. The installation bracket facilitates the stable installation of the equipment in various treatment places such as pools and oxidation ditches.

This equipment comes in a variety of specifications and can be flexibly selected according to factors such as the water volume, depth, and water quality requirements of the treated water body. It is widely used in municipal sewage treatment plants, industrial wastewater treatment stations, lake and river water body restoration, and other fields. It runs stably and reliably and has a significant energy-saving effect, making it a capable device for realizing efficient sewage treatment and improving the water body ecology.

WORKING PRINCIPLE

The working principle of the submersible high-efficiency and energy-saving mixing aerator is to achieve the dual functions of mixing and aeration by the submersible motor driving the impeller to rotate at high speed.

After the equipment is started, the submersible motor drives the impeller to rotate rapidly in the water. The powerful centrifugal force generated by the impeller lifts the sewage from below and drives the surrounding water body to rotate vigorously, enabling different components in the sewage, such as organic matter and microorganisms, to be fully mixed and evenly dispersed, avoiding the accumulation of local substances and enhancing the mass transfer effect of the entire water body.

At the same time, the aeration device continuously introduces external air into the water. Under the negative pressure generated by the rotation of the impeller and the shearing action of the water flow, the air is broken into tiny bubbles. These bubbles spread in the water body along with the water flow, greatly increasing the dissolved oxygen content in the water. The water body with sufficient dissolved oxygen provides a good living environment for aerobic microorganisms, allowing them to multiply in large numbers and decompose the organic matter in the sewage, thereby realizing the purification treatment of the sewage. In this process, the draft tube guides the water flow to flow in a specific direction, further strengthening the synergistic effect of mixing and aeration, making the contact between sewage and air more sufficient and improving the overall treatment efficiency.

MAIN PERFORMANCE AND CHARACTERISTICS

l High-Efficiency Mixing and Aeration Effects: Thanks to the uniquely designed impeller and the reasonable aeration device, it can achieve powerful mixing and uniform aeration at the same time, enabling the substances in sewage to be fully mixed and the dissolved oxygen to spread rapidly. This greatly improves the decomposition efficiency of organic matter in sewage. Whether it is dealing with organic pollutants in domestic sewage or complex components in industrial wastewater, it can demonstrate excellent treatment capabilities, effectively shortening the sewage treatment cycle and improving the treatment effect.

l Significant Energy-Saving Advantages: Adopting advanced energy-saving technologies, on the premise of ensuring the normal performance of the mixing and aeration functions, it optimizes the power configuration of the motor and the overall operating efficiency. Compared with traditional similar equipment, it can significantly reduce energy consumption and operating costs. In the long-term sewage treatment work, it can save users considerable electricity expenses, which conforms to the current development trend of environmental protection and energy conservation.

l Stable and Reliable Operation: Key components of the equipment, such as the submersible motor and the impeller, are all made of high-quality materials and have undergone strict quality inspections. They have good corrosion resistance, wear resistance, and sealing performance. Even in harsh underwater environments, they are not prone to malfunctions during long-term operation and continuously provide stable treatment capabilities for the sewage treatment system, reducing the downtime caused by equipment maintenance and replacement and ensuring the continuity of sewage treatment work.

l Simple Installation and Operation: The overall structure is compact, and the installation method is flexible. It only needs to be fixed in the corresponding treated water body through the installation bracket and connected to the power supply before it can be put into use, without the need for complex civil engineering and cumbersome debugging processes. Moreover, the operation is simple and easy to understand. Workers only need to control the start and stop of the equipment and adjust basic parameters such as the running time according to the actual situation. Ordinary personnel can master the operation method proficiently after simple training, facilitating its quick application in different places.

l Wide Applicability: Different parameters such as the model, power, and installation position of the equipment can be flexibly adjusted according to different water body environments, such as the water volume, water quality, water depth, and treatment requirements of sewage. At the same time, it can also be used in combination with other sewage treatment equipment. Whether it is in the biochemical reaction pool of a municipal sewage treatment plant, the aeration pool for industrial wastewater treatment, or the ecological restoration project of natural water bodies such as lakes and rivers, it can play an important role, has strong versatility, and can meet diverse treatment requirements.

APPLICATION FIELDS AND INDUSTRIES

l Municipal Sewage Treatment Field: In the activated sludge process of municipal sewage treatment plants, the submersible high-efficiency and energy-saving mixing aerator is one of the key equipment. It can fully mix and aerate the sewage in the aeration pool, ensure that the activated sludge has sufficient contact with the organic matter in the sewage, promote the decomposition and metabolism of the organic matter by microorganisms, effectively remove the pollutants in the sewage, ensure that the effluent quality meets the discharge standards, protect the urban water environment, and improve the living quality of residents.

l Industrial Wastewater Treatment Field: The wastewater generated by industrial production has complex and diverse components, and the treatment requirements for wastewater from different industries also vary. This equipment can adjust the operating parameters reasonably according to the characteristics of wastewater from various industries, such as chemical wastewater and printing and dyeing wastewater, to conduct targeted mixing and aeration treatment on the wastewater, improve the biodegradability of the wastewater, help the subsequent biochemical treatment process play a better role, achieve the discharge standards of industrial wastewater, reduce environmental pollution, and assist industrial enterprises to fulfill their environmental protection responsibilities.

l Water Body Ecological Restoration Field: For natural water bodies such as lakes and rivers, with the influence of economic development and human activities, water bodies often have problems such as eutrophication and deterioration of water quality. The submersible high-efficiency and energy-saving mixing aerator can increase the dissolved oxygen in the water body, activate the original microbial community in the water body, promote the natural degradation of pollutants in the water body, improve the fluidity of the water body, and restore the ecological functions of the water body, creating a healthy water ecological environment, which has a positive significance for the protection and restoration of the aquatic ecosystem.
