How to deal with coking plant removing phenol wastewater containing phenol
the current main methods of treatment of wastewater containing phenol using biological method, chemical method, physical method, etc. , and commonly used method is solvent extraction.
solvent extraction treatment of phenol wastewater with high recovery rate, solvent can be reused, and low cost. Traditional processing methods running cost is high, the processing is difficult, the efficiency is low, so is widely used in chemical plants, such as dyeing wastewater treatment.
in the solvent treatment wastewater containing phenol, principle of operation is the waste water containing phenol and suitable extractant 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. Extraction of the organic matter and add reverse extraction, extraction agent will phenol material separation and extraction agent, extractant recycling recycling.
operation flow chart of wastewater containing phenol:
at present mainly adopts the centrifugal extraction wastewater containing phenol machine for processing, compared with the traditional extraction, extraction tower, the working principle of centrifugal extraction machine with both the distinction that having essence. Centrifugal extraction machine is the use of motor driven rotary drum high-speed rotation, the density of different and each of two immiscible liquids in drum or under the action of shear force produced by the rotation of blades complete mixing and mass transfer, and the effects of the centrifugal force in the high-speed rotating drum under rapid separation.
centrifugal extraction machine has the remaining time is short, split phase quickly, high extraction efficiency, save the investment cost and solvent recycling cost advantages, on the separation of mixed effect is remarkable.
