| Summary: | 碩士 === 國立中央大學 === 化學工程研究所 === 82 === When use electrochemical treatment in the decolorization dyeing
effluent, it was always operated with metal as a cathode. The
metal cathode would react and dissolve in dyeing effluent. The
metal ion which was contained in effluent is another
pollution and increases the amount of sludge. The research use
carbon fiber and stainless steel as a cathode and an anode. The
equipment can be successful in remov- ing the color of dye from
aqueous solution and don`t increase any sacond pollution. But
this methode remove organic carbon very slowly. Following
experiment, organic carbon were removed 16% during 90 minutes,
but the dye was decomposed during 30 minutes. In order to
research the reaction of electrolysis and mechanism of color-
removing, choose Ｈ-type tube to treat dye solution. Then
cell was operated in batch mode to understand the variables of
operation (example：concentration of electro- lyte,
concentraion of dye solution, voltage and pH value of initial
dye solution, etc. ) and the effect of electrochemical
treatment. Applying the above result operate cell of flowing
cyclization mode. Cell of flowing cyclization mode can treat
large amount of dye solution but the flow rate of dye solution
must fit other operated condition. Following experiment, when
the flow rate of dye solution were 30 and 50 ml/min, the
decolor amount of per coulomb were 0.3 and 0.05mg.
