The integrated prefabricated pump station is mainly used in industrial and municipal engineering or other places where wastewater cannot be discharged into sewage treatment in the current construction, among them, urban areas and unmanned areas are mainly suitable for sewage pumping stations, while urban drainage is mainly suitable for tunnel prefabricated pumping stations, rainwater prefabricated pumping stations and sewage pumping stations.

Features of Integrated Prefabricated Pumping Station

The integrated prefabricated pump station has many advantages. Compared with the traditional pumping station, it has been widely used in urban wastewater treatment design. The pumping station is mainly composed of a glass fiber reinforced plastic cylinder with submersible sewage pumps, water inlet, and outlet pipes, guide rods, automatic coupling devices, and control systems.

It is suitable for sewage (rainwater) discharge in low-lying areas of cities and towns, low-lying sewage (rain) water discharge and treatment in urban residential communities, agricultural water conservancy irrigation, long-distance transportation of urban sewage pipes, and sewage (rainwater) discharge in low-lying areas in scenic areas aspect.

The main features of integrated prefabricated pump station are as follows:

• Short construction period and simple construction, the installation of the entire integrated prefabricated pump station can be completed in about 2 weeks. It can be assembled directly by the factory and sent to site for installation. After installation, the surrounding environment and landscape will not be affected.
  
  During construction, it only needs to prefabricate the bottom plate of the integrated  pumping  station and complete the excavation of the foundation pit.The entire integrated prefabricated pump station has a compact structure, a short installation  period, and a small amount of construction, and it is more convenient to move.
  
  When installing major equipment such as submersible sewage pumps, the integrated  pumping station uses a dual-rail automatic installation system for pumps, which not  only protects the personal safety of the staff but also makes the installation work is  simpler and more convenient.

• The cost price of integrated prefabricated pump station is lower, saving installation costs. The entire internal structure of the integrated prefabricated pump station is compact,  and all its components are completed in the factory.
  
  After leaving the factory, integrated prefabricated pumping station can be installed  directly with a crane. Compared with the traditional pumping station, civil engineering  is 1/10 of the traditional concrete structure, and the total cost is only 1/3 of the  traditional concrete structure.
  
  This installation method of the integrated prefabricated pump station saves 20% in cost than traditional pumping station.

• The integrated prefabricated pump station can be controlled remotely, without the need to arrange personnel on duty. The staff can modify or change the parameters of the prefabricated integrated pumping station online, which not only reduces maintenance costs but also ensures the safety of  management personnel.
  
  When the control cabinet fails, perform an emergency operation through the emergency operation switch of the sewage pumping station.  The complete set of booster equipment for the pumping station has been tested by the factory and set up as required for operation before shipment.
  
  The integrated prefabricated pump station has certain emergency measures and a complete set of booster equipment for backup. When the control cabinet fails, in order to ensure the smooth working of the pump station, it can turn on the emergency operation switch when it fails.

• The materials used in the integrated prefabricated pumping station are durable and strong, and most of its main structure is made of fiber-wound fiberglass reinforced plastics, so the service life is longer.
  
  The integrated prefabricated pumping station is designed with advanced anti-corrosion  materials with a service life of about 50 years and has good mechanical strength.
  
  The prefabricated pump station has the mixing and flushing function of the matching  water pump, which not only reduces the loss when the pump station is frequently replaced but also increase the life of the pump station.

• Convenient maintenance
  
  Compared with the traditional pumping station, the integrated prefabricated pumping  station is easy to maintain and maintain and has a higher safety factor.
  
  The cylinder of the prefabricated pump station adopts a sealing device, and the whole is buried deep underground, and there is no peculiar smell overflow.

Apart from the above advantages, the integrated prefabricated pumping station has some other shortcomings. Affected by the rigidity and size of the cylinder material, it is impossible to deepen the integrated pumping station indefinitely when the urban sewage pipe network is buried deeply. Tuohai Pump Industry can provide a maximum depth of 18 meters and a diameter of 3.8 meters.

In the actual work process, when the sewage flow is too large, the requirements for the volume of the integrated prefabricated pumping station are also getting higher and higher. It is very difficult for a large flow submersible pump to be installed in a cylinder of conventional size.

Therefore, the integrated prefabricated pumping station cannot be used in pumping stations that require a large flow rate and a large buried depth. The maximum processing water volume of the integrated prefabricated pumping station of Tuohai Pumps is about 40,000m³/d.

Design of the Integrated Prefabricated Pumping Ptation

 

• The maximum diameter of the wellbore of the integrated prefabricated pumping station  shall not exceed 3.8 meters.

 

• A maximum of three pumps can be installed in a single wellbore of the integrated  prefabricated sewage pumping station, one of which is a spare pump. In a traditional sewage station, the volume of the collection well must be greater than the output water volume of the pump at the maximum flow rate. For the integrated prefabricated  pumping station, it can be set to use multiple wellbores in parallel when the sewage  volume is maximum.

• There are certain regulations for the number of sewage pumps to be opened, which is less  than or equal to 6 times per hour.
  
  However, some advanced pumps of Tuohai Pumps have reached 20 times, and the most  common pumping stations have also reached 10 times, which improves the scale of an  integrated prefabricated pumping station.

Application Examples

With the continuous acceleration of the urbanization process, urban sewage discharge has also continued to increase. Surface water quality continues to deteriorate due to excessive sewage. In order to improve the sewage collection rate, it is necessary to build a corresponding sewage supporting pipe network.

Due to the lag of the original planning and the acceleration of urbanization, integrated prefabricated pumping stations should be widely used in urban sewage facilities, which have a short construction period, small investment, small footprint, small impact on the surrounding environment, and advanced control systems, Good leakage and noise control, and a high degree of cooperation of components.

In the actual urban sewage design, sewage pumping stations can be used in various decentralized sewage collection systems, the urban residential communities, urban low-lying areas, agricultural irrigation, sewage pipe network midway lifting, drainage of bridges and culverts.

Setting up a crushing grid at the entrance of the sewage pumping station can effectively ensure the safety and reliability of the running of the pumping station.

In addition, in the supporting system of the integrated prefabricated pump station, there are ion deodorization device, automatic guide rail device, metering alarm system and water level control system, etc., which can not only realize fully automatic operation but also scientifically and reasonably control the operation of the pump.

Concluding Remarks

In summary, the integrated sewage pumping station is a major advancement in the sewage treatment system and an indispensable part of urban sewage treatment. It has been widely used in the urban sewage system and used as an upgrade in the sewage treatment process. The pumping station has completely replaced the traditional pumping station.

  

The integrated prefabricated pumping station has obvious advantages compared with the traditional pumping station. It has the characteristics of a high degree of automation, low cost, short construction period, small area, convenient installation, and high integration.

  

When designing an integrated prefabricated pumping station, it is necessary to fully consider related issues such as the volume of the sump, the number of pumps, and the water depth of the pumping station, and meet the requirements of relevant standards, so that it can play its greatest role in urban sewage treatment and expand the further promotion of integrated prefabricated pumping stations.
