AFP submersible sewage pump: How to become the green guardian of urban sewage treatment?

Urban sewage treatment is a complex and sophisticated system engineering, the core of which is to efficiently and stably remove harmful substances in sewage so that it meets the discharge standards or the water quality requirements for direct reuse. This process faces multiple challenges: sewage sources are diverse and the composition is complex, including organic matter, inorganic matter, microorganisms and even heavy metals; the treatment volume is large, requiring the treatment equipment to have high efficiency and continuous operation capabilities; furthermore, with the increasingly stringent environmental protection regulations, the requirements for effluent water quality are constantly increasing, which puts higher requirements on the advancement and flexibility of treatment technology. Choosing efficient and reliable sewage treatment equipment has become the key to improving overall treatment efficiency.

As a pump product designed for sewage treatment, AFP submersible sewage pump stands out among many pump types with its unique design concept and advanced technical characteristics. Its core advantages are mainly reflected in the following aspects:
Non-clogging design: In response to the common solid particle clogging problem in sewage treatment, the AFP submersible sewage pump adopts a large channel design and an impeller of special materials, which can effectively chop and transport sewage containing large particle impurities such as fibers and plastic fragments, avoiding the disadvantages of easy clogging of traditional pumps and ensuring the continuity and stability of sewage treatment.
High-efficiency operation: With advanced fluid dynamics design and high-quality motors, the AFP submersible sewage pump minimizes energy consumption while ensuring strong suction capacity, thereby improving the efficiency of the overall treatment system. This is of great significance for reducing operating costs and energy consumption.
Strong corrosion resistance: In view of the fact that sewage may contain corrosive substances, the AFP submersible sewage pump uses corrosion-resistant materials such as stainless steel and cast iron coated with plastic, which effectively extends the service life of the equipment and reduces the maintenance frequency and cost.
Automatic control and monitoring: Modern AFP submersible sewage pumps are often equipped with intelligent control systems that can monitor the working status of the pump in real time, automatically adjust operating parameters, and even remotely control, greatly improving the convenience of management and the automation level of the system.

In all links of urban sewage treatment plants, AFP submersible sewage pumps play an irreplaceable role:
Pretreatment stage: Before sewage enters the biological treatment system, AFP submersible sewage pumps are responsible for extracting raw sewage from the collection pipe network and sending it to the screen decontamination machine for preliminary cleaning, laying a good foundation for subsequent treatment.
Bioreaction tank: In biological treatment units such as activated sludge method or biofilm method, pumps are used in key links such as mixed liquor return and sludge return to ensure the efficient biological reaction and improve the removal rate of organic pollutants.
Secondary sedimentation tank and subsequent treatment: In the secondary sedimentation tank, AFP submersible sewage pumps are used to discharge residual sludge. At the same time, in the deep treatment stage, such as sand filtration, carbon filtration, membrane treatment, etc., the pumps also play the role of conveying medium to ensure that the effluent water quality meets the standards.
Emergency treatment and sludge treatment: In the face of sudden water pollution incidents or sludge dehydration process, the rapid response capability and strong conveying capacity of AFP submersible sewage pumps provide strong support for emergency treatment and harmlessness and reduction of sludge.

With the increasing global awareness of environmental protection, realizing the resource utilization of urban sewage has become an important direction for urban green development. With its high efficiency, stability and environmental protection, AFP submersible sewage pump not only improves the efficiency and quality of urban sewage treatment, but also creates conditions for the recycling of water resources. By reducing energy consumption, reducing treatment costs and improving effluent quality, AFP submersible sewage pump helps cities build a greener and more sustainable water circulation system, promoting the harmonious coexistence of man and nature.
