Sewage lifting pump station

Sewage lifting pump stationIt is an important component of the sewage system, characterized by continuous water flow, small water flow, but large fluctuations, and high levels of pollutants in the water. Therefore, the design of the water collection tank should have sufficient storage capacity and consider backup pumps. In addition, the design should minimize environmental pollution and provide good management and maintenance conditions within the station.

1、 Overview of sewage lifting pump station

A sewage lift pump station is a specialized facility for treating sewage. Usually located in low-lying areas or underground, it is a treatment facility used to pump sewage from a low place to a high place for better treatment of sewage. A sewage lift pump station is usually composed of sewage lift pumps, pipelines, control systems, and other equipment. Its function is to pump sewage from low to high, treat it, and then discharge it into the urban sewage network. The operation and management of sewage pumping stations are crucial, as their efficiency and safety directly affect urban environmental sanitation and public safety.

A sewage pumping station is an engineering facility used in urban drainage engineering to pump and transport sewage. When the sewage in the sewage pipeline cannot be transported or discharged by gravity, or when the construction is difficult due to the deep burial of the pipeline, or when it needs to be pumped up at the end of the main pipeline before entering the sewage treatment plant, a sewage lifting pump station must be installed. The sewage lift pump station is an important component of the sewage system, characterized by continuous water flow, small water flow, but large variation amplitude, and high pollutant content in the water. Therefore, the design of the water collection tank should have sufficient storage capacity and consider backup pumps. In addition, the design should minimize environmental pollution and provide good management and maintenance conditions within the station.

2、 Classification of sewage pumping stations

Divided into two types:

One type is an integrated pumping station installed in the sewage pipeline system for pumping urban sewage. The function is to raise the elevation of sewage, because unlike water supply pipes (tap water), sewage pipes do not have pressure and rely on the gravity of sewage to flow naturally. Due to the wide area of sewage collected by urban sewage interception network pipes, they are far away from sewage treatment plants. It is impossible to bury the pipeline very deep, so a pumping station needs to be set up to raise the elevation of the sewage.

2、 It is a pumping station set up in the sewage treatment plant to lift sewage, which provides water flow power for subsequent processes. Generally speaking, the height of sewage lifting is calculated by subtracting the head loss from the elevation of the effluent discharged after sewage treatment, and deducing it backwards.

3、 Purpose of sewage lifting pump station

Sewage pumping stations are often used for drainage and waterlogging in low-lying areas. They raise the water level of rainwater or domestic sewage, pressurize and transport it to a certain height through water pumps, and then gravity flow into municipal pipelines or discharge pipelines. Therefore, sewage pumping stations are commonly used in households, commercial areas, subways, schools, and factories for the discharge of sewage and rainwater.

The function of Dream Clean sewage lifting pump station

1Used for drainage and waterlogging in low-lying areas, reducing the destructive effect of rainwater on land and environment;

2Discharge commercial or industrial wastewater, protect the surrounding environment, and make living and working environments healthier;

3To solve problems such as large drainage volume and slow drainage, and to ensure timely discharge of sewage.

4、 Advantages of sewage pumping station

1The finished pump station has a short construction period and can be used immediately after installation.

2Integrated pumping station, occupying small space, can effectively alleviate the shortage of urban land.

3The pump station cylinder is made of corrosion-resistant materialHDPEOne time casting molding, no leakage, long service life.

4Backwash function, automatically cleans the interior of the pump station, reducing maintenance costs.

5The internal pipeline adoptsDN50Stainless steel and using GermanyEMGRExcellent performance.

5、 Parameters of sewage lifting pump station

The main parameters are as follows:

Total traffic category:5~3600m3/hRated power of motor:0、37~160kWTotal number of pumps:1~4Table, working temperature:-40℃~40℃. Permissible substances: precipitation, domestic sewage treatment, sewage, and other substances that do not have abrasive residues or long chemical fiber residues, and that corrode water pumps with organic chemicals or mechanical equipment, with a temperature of0℃~20℃.

Cost savings: The pump station is supplied as a complete set of equipment, and all internal installation and adjustment work is carried out in the processing plant. Only the overall installation of the pump station is required on site, reducing the civil engineering cycle time and project cost, and reducing the overall project investment and usage period of the community owners; The next material for the sewage lifting pump station is fiberglass anti-corrosion, and internal spare parts will be usedSUS304With anti-corrosion materials such as hot-dip galvanizing, no maintenance is required, and all normal use periods have been reached30About a year.

Convenient maintenance: The water pump and basket are all equipped with sliding rails, which can be quickly disassembled and installed during maintenance. Expansion of the role of sewage pumping stations: pre embedded communication sockets for convenient customer management.
