  1. An integrated process of wastewater treatment and utilization is presented. the process is made up of heating the soft water of room temperature by high temperature printing and dyeing wastewater via heat exchangers, reusing the low level base decrement wastewater of water washing for dust control and desulphurizing of stack gas and anaeration - aeration biological treatment of printing and dyeing wastewater. this process has fair economical benefit on the principle of so called waste control by waste itself. this might be an ideal process for printing and dyeing wastewater treatment and disposal, the effluent of this process is quite enough to meet the requirement of urban sewer collector. additionally also many advantages are attractive such as the complete return of biological sludge to digestion, no chemicals dosage and free of secondary pollution
