Waste Water Treatment Pump

Waste water pumps for sewage

Our waste water pumps can purify wastewater from household and business's
sewage systems, which is also called sewage treatment plant, or STP for short.
Meanwhile, there also increase more cases to tackle with the contaminated
groundwater.

According to the classification of sewage sources, it's generally divided into
production sewage treatment and domestic sewage treatment. The production
sewage treatment by using our sewage pump includes industrial sewage,
agriculture sewage, medical sewage and so on, while the sewage generated in our
daily life means domestic sewage. There are many more forms of the inorganic
and organic complex mixture in the sewage. So our sewage water pumps are widely
used to deal with them in order to make them available for dewatering and been
reused in the world.

Sewage water pump processes

The sewage treatment plant process is split into three grades.

Primary treatment, which belongs to physical treatment, mainly removes solid
pollution in a suspended state in sewage. Most of the physical treatment
methods can only meet the primary requirements, but it's necessary. After
primary treatment of sewage, BOD can generally be removed about 30%, not up to
the discharge standard. Primary treatment is the pretreatment of secondary
treatment.

Secondary treatment, mainly to remove the colloidal and dissolved organic
pollutants in sewage (BOD, COD), removal rate can reach more than 90% that can
be generally discharged and used for irrigating. At this process, sewage
transfer pump can be used to do tertiary treatment, which is the further
treatment of the refractory organic matter, nitrogen, phosphorus and other
soluble inorganic matter can lead to eutrophication of water.The main methods
are biological nitrogen and phosphorus removal method, coagulation
sedimentation method, sand filtration method, activated carbon adsorption
method, ion exchange method and electroosmosis analysis method.

The whole process for raw sewage through the coarse grid through the sewage
pump after the ascension, flows through the grid or sand filter, and then enter
the grit chamber, after sand water separation of wastewater into the settling
basin for the first time, the above as the primary treatment, the pond water
into biological processing equipment, at the beginning of the activated sludge
and biological membrane method, (including aeration tank reactor of activated
sludge method, oxidation ditch, etc., biological membrane method including
biological filter, biological rotating disc, biological contact oxidation and
biological fluidized bed), biological treatment of effluent into the secondary
sedimentation tank, the second pond, by using water pump for sewage, the water
is disinfected emissions or entering tertiary treatment, primary treatment to
the end of the for secondary processing,The three treatments include biological
nitrogen and phosphorus removal, coagulation and precipitation, sand
filtration, activated carbon adsorption, ion exchange and electrodialysis. Part
of the sludge from the secondary sedimentation tank goes back to the primary
sedimentation tank or biological treatment equipment, part goes into the sludge
concentration tank, and then into the sludge digestion tank. After dehydration
and drying equipment, the sludge is finally used.
