INTRODUCTION

The body housing is usually made of high-quality stainless steel or high-strength engineering plastics, possessing good corrosion resistance and sturdiness. It can adapt to the complex chemical environment of sewage and meet the long-term usage requirements, providing reliable protection for internal components. The motor, as the power source, can provide a stable driving force for the operation of the equipment to ensure that the mixing and aeration work can be carried out continuously. The mixing impeller has a unique shape and structural design. When it rotates, it can generate a powerful plug flow effect, making the sewage flow in an orderly manner in a specific direction while achieving a good mixing effect. The aeration system is responsible for efficiently dispersing air into the sewage to increase the dissolved oxygen content in the water and create favorable conditions for microorganisms to decompose pollutants. The installation bracket facilitates the stable installation of the equipment in sewage treatment tanks and other corresponding places to ensure its normal operation.

This equipment comes in a variety of specifications and can be flexibly selected according to factors such as the sewage treatment volume, tank structure, and treatment process requirements. It is widely used in municipal sewage treatment plants, industrial wastewater treatment stations, and various biochemical treatment process links. It runs stably and reliably and is easy to operate, making it a capable assistant for efficient sewage purification.

WORKING PRINCIPLE

The working principle of plug flow mixing aerators is based on the coordinated operation of the plug flow effect of the mixing impeller and the oxygenation function of the aeration system. After the equipment is started, the motor drives the mixing impeller to start rotating. Relying on its special structure and the centrifugal force generated by high-speed rotation, the mixing impeller exerts a forward thrust on the sewage, prompting the sewage to flow in a plug flow state along the set direction.

During the flow of the sewage, the mixing impeller simultaneously vigorously stirs the surrounding sewage, enabling the organic matter, microorganisms, and other components in the sewage to be fully mixed, avoiding the accumulation of local substances and uneven reactions, and improving the overall mass transfer effect of the sewage. Meanwhile, the aeration system continuously transports external air into the sewage. After entering the sewage, the air is dispersed into a large number of tiny bubbles through the aeration device. Driven by the plug flow, these bubbles are evenly distributed in the sewage, greatly increasing the dissolved oxygen content in the water. Sufficient dissolved oxygen provides an ideal living environment for aerobic microorganisms in the sewage, enabling them to decompose pollutants such as organic matter in the sewage more efficiently, thus gradually realizing the purification treatment of the sewage and making the water quality indicators of the sewage continuously approach the discharge or reuse standards.

l Excellent Aeration and Oxygenation Capacity: The aeration system adopts advanced aeration technology, which can break air into tiny and uniform bubbles, giving them good dispersibility and residence time in the sewage, maximizing the increase in the dissolved oxygen content in the water, providing sufficient oxygen guarantee for the growth and reproduction of microorganisms and the decomposition and metabolism of pollutants, enhancing the biochemical reaction effect of sewage treatment, and improving the effluent water quality.

l Stable and Reliable Operation: The equipment selects high-quality key components such as motors and impellers, which have undergone strict quality inspections and durability tests. In the face of different water qualities, water volumes, and complex working environments, it can still operate stably, is not prone to malfunctions, reduces the treatment interruptions caused by equipment maintenance and repair, continuously provides stable treatment capabilities for sewage treatment work, and reduces the operation and management costs.

l Simple and Easy Operation: The overall operation process is relatively simple. Workers only need to control the start and stop of the equipment and appropriately adjust the operating parameters (such as the motor speed) according to the actual situation. There is no need for complex professional knowledge and operation skills. Ordinary personnel can master the operation method proficiently after simple training, facilitating its quick deployment in various sewage treatment sites and improving work efficiency.

l Strong Application Flexibility: Different equipment models, powers, and installation methods can be flexibly selected according to factors such as different sewage sources, treatment scales, treatment processes, and tank layouts. It can also be used in combination with other sewage treatment equipment. Whether in the activated sludge process, oxidation ditch process of municipal sewage treatment plants, or the biological contact oxidation process in industrial wastewater treatment and other links, it can play an important role and meet diverse sewage treatment requirements.

APPLICATION FIELDS AND INDUSTRIES

l Municipal Sewage Treatment Field: In many treatment processes of municipal sewage treatment plants, plug flow mixing aerators play a key role. For example, in the aeration tank of the activated sludge process, it enables the activated sludge to have sufficient contact and reaction with the organic matter in the sewage through plug flow and aeration, allowing microorganisms to efficiently decompose pollutants and ensuring that the effluent water quality meets the discharge standards, laying the foundation for the improvement of the urban water environment and the improvement of residents' living quality.

l Industrial Wastewater Treatment Field: The wastewater generated by industrial production has complex and diverse compositions, and the characteristics of wastewater from different industries vary greatly. This equipment can adjust the operating parameters reasonably according to the characteristics of wastewater from industries such as chemical, printing and dyeing, and food processing, realizing effective plug flow, mixing, and aeration of the wastewater, improving the biodegradability of the wastewater, assisting the subsequent biochemical treatment links to better remove harmful substances in the wastewater, achieving the discharge standards of industrial wastewater, reducing environmental pollution, and helping industrial enterprises fulfill their environmental protection responsibilities.
