I. Product Introduction
Integrated rainwater pumping stations, also known as integrated pumping stations, integrated prefabricated pumping stations, integrated lifting pumping stations, and integrated wastewater pumping stations, are buried underground for collecting rainwater and wastewater. After preliminary treatment like mixing, the treated wastewater is pressurized and lifted, then transported through pipelines to the wastewater treatment plant.
Integrated pump stations are designed to provide potential and pressure energy for water, addressing issues related to drainage, irrigation, water supply, and water resource allocation under non-spontaneous flow conditions. As the mainstream solution today, traditional concrete pump stations are used in drainage systems. Over time, traditional pump stations have also exposed some drawbacks that are difficult to overcome, such as easy corrosion of pool walls, sedimentation of impurities in the pump pit, and low integration difficulty, making effective management and monitoring challenging.
An integrated pump station is a fully pre-fabricated, underground pump station tailored to the specific requirements of the customer and factory-assembled. Our company, Pinyue Environmental Protection, can now produce pump stations in various materials including fiberglass, PPH, HMPP, and buried box-pump integrated fire pump stations. These stations are internally equipped with pumps, grates, pipelines, valves, instruments, control equipment, and maintenance facilities, significantly ensuring the cost-effectiveness and operational reliability of the system. With numerous successful operation cases, integrated pump stations are widely used in urban waterlogging prevention, rainwater and wastewater collection and treatment, and other fields.
Section 2: Product Principle
The liquid level information from the pressure sensor or float ball feedback to the control system is then used to adjust the pump operation based on the set parameters. When the liquid level reaches the set level for pump activation, the control system initiates the pump, allowing wastewater to be pumped to the municipal sewage pipeline outlet. If the wastewater pumping level falls below the set level, the system shuts down the pump. This continuous cycle ensures the smooth operation of the integrated pumping station.
Three, the primary function of the integrated pumping station:
1. Harvest urban rainwater, river water, and lake water to prevent waterlogging due to rising water levels, and then transport the water to waterworks, residential use, and agricultural irrigation for municipal water accumulation.
2. Collect wastewater directly discharged from municipal factories and residential areas, mix it using格栅 and submersible pumps within the wastewater pumping station, ensure the pipes are free of silt and blockages, and boost water level and pressure to transport it to the wastewater treatment plant.
The wastewater treatment plant's role is to receive sewage from the pumping station, undergo filtration and disinfection processes, and then be sent to the recycled water channel for industrial use and toilet flushing.
Four, integrated pump station installation method
Based on varying operational conditions, different installation methods are employed to ensure the long life and high efficiency of integrated pump stations to a great extent. Under normal circumstances, it is recommended to use:
1. Full-in内置subsurface wet well pump station installation method, in addition to which, the following can be adopted:
External Valve Wet Well Pump Station
3. Dry and Wet Separation Pump Station
4. Pump stations with repair room and other installation methods
Customers may decide the specific installation method of the integrated pumping station based on the design or the specific on-site usage conditions.
Five, Main Application Environments
