| Abstract: | Treatment of simulated and actual dyeing wastewater with organic flocculant PYM which was prepared by the reaction of glyoxal, a kind of dicyan and some additional reagents has been studied. The results showed that the purifying efficiency of PYM is related to type of dyestuff and depended on pH value of wastewater and dosage of PYM, the removal rate of chromaticity and CODCr could reach 97.0 ~ 99.9% and 65 - 86% respectively under suitable condition. The mechanism of decolorization reaction indicated that the chemical reaction of dye (X-3B) with PYM occurred by ionic bond and hydrogen bond, the bonding and aggregation lead to flocculation and sedimentation of dyes in wastewater. |
