steel tanks for wastewater storage introduce

Steel tanks for wastewater storage has a lot of kinds, save for a large sewage tank is now the latest application of enamel assembled tank, long life and corrosion resistance, can meet the requirements of rapid construction.

steel tanks for wastewater storage

Steel tanks for wastewater storage apply to process of purifying the water in a water body or in the water that is used again. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, health care, food and other fields, are increasingly walk into the daily life of ordinary people.

Modern sewage treatment technology can be divided into primary, secondary and tertiary treatments according to the degree of treatment, and the degree of sewage treatment is generally determined according to the water quality status and the whereabouts of the treated water. At different stages, different wastewater storage tanks are required to be used for cache filtering.

steel tanks for wastewater storage mainly removes the suspended solid pollutants in the wastewater, and the physical processing method can only meet the requirements of the first order processing. After treated sewage, BOD generally can be removed about 30%, steel tanks for wastewater storage which can not reach the emission standard. Primary treatment is secondary treatment pretreatment.

steel tanks for wastewater storage mainly went into a state of colloidal and dissolved organic in wastewater pollutants (BOD, COD material), the removal rate can reach more than 90%, to organic pollutants emission standards, suspended solids removal rate of 95% water effect is good.

steel tanks for wastewater storage of NVirotech through the coarse screen raw sewage after sewage lift pump ascension through the grille or sieve rate, after enters the grit chamber, after sand water separation of wastewater into the settling basin for the first time, more than for primary treatment (namely physical 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.

steel tanks for wastewater storage 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, the water is disinfected emissions or entering tertiary treatment, primary treatment end to this as the secondary treatment, tertiary treatment including biological denitrification and phosphorus removal, coagulation sedimentation, sand filtration, activated carbon adsorption, ion exchange and electrodialysis method.
