ferent time, and calculate the degradation rate of SDBS.

2.4. Analytical Methods

Chemical oxygen demand as permanganate demand (COD) and suspended solids (SS) were determined accord-ing to the methods described in the standard methods for the examination of water and wastewater [9]. Chroma-ticity and turbidity were measured using a Hach model DR890 photometer. The concentrations of dyes and SDBS solution were determined by using a Lambda 950 (PerkinElmer) spectrometer.

2.5. Experimental Setup

The continuous combined process for washing and dyeing wastewater consists of coagulation and settling reac-tor and photocatalytic system. A flow diagram of the continuous washing and dyeing wastewater treatment sys-tem used in this study is shown in Figure 1. Flocculation pretreatment was carried out in an up-flow inner cir-culation coagulation and settling reactor. The washing and dyeing wastewater with a certain velocity into the flocculation sedimentation tank, while adding nano flocculant, the waste water and the nano flocculant mixed rapidly within the reactor settlement, removing most of the chroma and COD, and then the sludge discharged from the bottom. The supernatant from the upper overflow weir inflow photocatalytic reactor, after photocataly-tic degradation in the sunlight further the removal of COD, to achieve the reuse standard.
