摘要：

The investigation presented here focussed on the steel industrial wastewater (SIWW) FeCl3 rich as an original coagulant to remove the textile wastewater. Central composite rotatable design experiment is used to study the effect of coagulation process for textile wastewater and to optimise the variables such as coagulant dosage and initial pH, which influence the efficiency of colour and COD removal of this effluent. A model has been obtained among decolourization, COD reduction and relevant parameters by means of variance analysis and obtained model was optimized. The efficiencies of decolourization and COD reduction for textile wastewater were accomplished at optimum conditions as 98% and 91%, respectively.
