  Overview of sewage lifter: sewage lifter is an integrated sewage discharge system composed of sewage pump, water collecting tank, pipeline, valve, liquid level gauge and electrical control device
It is mainly used for the lifting and discharge of waste water discharged from sewage pipes and sanitary facilities that are lower than the sewer liquid level or far away from the municipal sewage pipe network
It collects the waste water discharged by the sewage pipe and sanitary facilities that are lower than the sewage level or far away from the municipal sewage pipe network through the water collecting tank, and lifts and pumps it to the urban sewage system

Generation of sewage lifter:
At first, a cement sump was designed in the basement for basement drainage in China
Toilet sewage, bathroom sewage and washstand sewage were discharged into the sump on the same floor through pipelines
Two submersible pumps are installed in the sump, which is commonly referred to as & ldquo; One pit and two pumps & rdquo; Underground sewage discharge mode
Double pumps work alternately to ensure the reliability of blowdown
However, the biggest disadvantage of this working method is to clean and smell regularly
The basement itself has no windows, and the peculiar smell cannot be discharged
The peculiar smell makes the basement unusable
Moreover, regular clearing is also a fatal disadvantage of this underground drainage method
Later, with the introduction of sewage lifter from abroad to China, this kind of & ldquo; One pit and two pumps & rdquo; The drainage mode of the basement is gradually replaced by the sewage elevator
The biggest feature of sewage elevator is no peculiar smell and no cleaning

Principle of sewage lifter:
The sewage enters the water separator through the first check valve and is distributed by the water separator and then passes through → Check valves 1 and 2→ Debris separators 1 and 2 flow into the water storage tank
The debris in the sewage is filtered in the debris separator
After separation, it is temporarily stored in debris separators 1 and 2, and the filtered sewage enters the water tank; When the water level of the sewage in the water storage tank reaches the set height, the automatic control system starts the sewage pump 1 to discharge the sewage in the water tank, uses the pressure of the discharged sewage to flush out the sundries temporarily stored in the separator 1 and discharge them to the sewage pipeline outside the basement through the check valve 1
At this time, the discharge pressure of the sewage will close the check valve 1; When the sewage pump 1 and the check valve 1 pipeline system work, the sewage pump 2 is closed, the sewage flows into the water tank through the check valve 2 pipeline, and the sundries are separated through the sundries separator 2
When the sewage in the water tank drops to the set water level, the sewage pump 1 automatically stops working; When the water level in the water tank reaches the set height again, the automatic control system starts the sewage pump 2 to discharge the sewage in the water tank, uses the discharged sewage pressure to flush out the sundries temporarily stored in the sundries separator 2 and discharge them to the sewage pipeline outside the ground through the check valve 2
At this time, the pressure of the sewage will close the check valve 2
When the water level in the water storage tank drops to the lower limit of the set water level, The sewage pump 2 automatically shuts down and stops working;
The automatic control system makes the sewage pumps 1 and 2 operate alternately and repeat the above work;
There are two sets of independent debris separators in the double pump equipment
Therefore, when the two pumps operate alternately under full-automatic control, the continuous inflow of sewage will not be affected, and the water facilities in the basement can be used continuously and normally

Advantages of sewage lifter:
1、  No blockage: due to the separation technology of impurities and sewage, the impeller of the water pump does not contact sundries, which avoids the blockage of the pump

2、  No backflow of sewage: because the inlet pipe adopts double check valve, the possibility of backflow of sewage is reduced

3、  There is no dirt deposition in the ponding tank: due to the cyclone Scouring at the bottom of the tank, the deposition of dirt is avoided

4、  Reliable water level monitoring of sewage tank: the water level monitoring and control is sensitive to ensure the reliability of water pump start and stop
5、  No pollution: the sewage is stored and discharged in a closed manner, so the sewage will not overflow and has no odor, which protects the surrounding environment

6、  No cleaning: sewage and impurities are separated and discharged together when discharged, which truly realizes no cleaning

7、  Improve the utilization rate of buildings: this series of equipment has compact structure and small floor area, saving the space in the basement

8、  Automatic control operation: due to the use of single chip microcomputer and PLC control, it realizes the functions of automatic operation, cluster monitoring, fault alarm and so on

9、  Automatic sterilization and disinfection can be realized: according to the needs of users in different occasions, automatic sterilization and disinfection can be carried out and discharged up to the standard

Application of sewage lifter: sewage discharge in the basement of various buildings
1、  Sewage discharge of underground kitchen and toilet

2、  Sewage discharge after reconstruction of civil air defense project

3、  Small and medium-sized unmanned sewage transmission pump stations in urban areas

4、  Sewage discharge from subway stations and underpasses

5、  Sewage discharge from underground shopping malls, restaurants, baths and other service places

6、  Sterilization, disinfection and standard discharge of sewage from various health institutions
