| Abstract: | m -Hydroxy diethyl aniline is one kind of dyeing intermediates which have high concentration of COD _(Cr) and salinity and various components in their produced wastewater. A wastewater pretreatment method was applied to study on the feasibility and effect of the treatment. A treatment process that aeration followed by electrolysis was founded. The results showed that the removal efficiency approached to 20% and 82% respectively and the method can improve biological treatment. The optimum process condition was that aeration pH value 4.0 or so, aeration time 90 minutes;voltage value 7 V, electrolysis remained time 120 min, electrode space 3cm when electrolyzing. |
