The research investigated the performance of combined process (flocculation pretreatment-pho- to catalysis). The characteristics of nano flocculation and photocataly were evaluated by simulated dye and surfactant wastewater. In the coagulation and settling period, decolorization rate of five dyes wastewater by nano flocculant was higher than 95%. In the photocatalytic period, degradation of twelve sodium dodecyl benzene sulfonate reached 33%. Washing and dyeing wastewater treated by combined process conformed to the “textile dyeing and finishing industry back to the water quality standard” (FZ/T 01107-2011). The results showed that the combined process was highly advanced treatment for washing and dying wastewater.
