Aluminum metal elements with centrifugal extraction solvent extraction wastewater
With the development of aluminum industry, will produce a large amount of waste water in the process of aluminum production and processing, which contains the metal elements such as aluminum, nickel, chromium, if direct discharge of such wastewater, will cause serious harm to the environment and human body, so the need for wastewater treatment, avoid the pollution of the environment.
aluminum wastewater treatment generally have chemical method and biological method, physical method, through the experiment found that solvent extraction of aluminum wastewater treatment effect is remarkable.
a solvent extraction, aluminium wastewater treatment principle:
aluminum wastewater containing aluminum, nickel, chrome and other metal elements, with zhengzhou days. cwl - extraction technology research and development production
M series centrifugal extraction machine, using the method of solvent extraction, first to adjust acid waste liquid, the material liquid metal elements in precipitation, then add the hydrochloric acid to dissolve in the material liquid, then extraction with P507, and some metal elements in the material liquid extract, extract residual phase after pretreatment can undertake biochemical into the subsequent section.
centrifugal extraction machine in operation, the aluminum wastewater with P507 according to certain proportion into the centrifugal extraction machine, with the aid of the rotation of the drum, through the impeller the two-phase mixing and dispersing quickly, and complete the mixing and mass transfer process.
After mixing liquid under the action of vortex disk into the rotary drum, in under the action of centrifugal force, two phase fluid fast separation and through different export eduction body, to complete the two phase separation process.
M centrifugal extraction machine is a new, rapid, efficient liquid-liquid extraction separation equipment.
The series centrifugal extraction machine level reserved time is short, split phase quickly, high extraction efficiency, save the investment cost and solvent recycling fee.
