Abstract


A new 17,000 tons/day printing and dyeing wastewater treatment facility and related supporting facilities were constructed in the Haiyan section of the Yangtze River Economic Belt. Equipment installation was based on the initial scale of 13,000 tons/day for the enterprises entering the park. This paper introduces the designed influent and effluent water quality indicators, the process selection for major structures, and the parameter design of the wastewater treatment plant. The plant features a dedicated acid precipitation pretreatment line for a small amount of high-concentration wastewater. The main treatment process handles the integrated wastewater, which is a mixture of low-concentration wastewater and the filtrate from the high-concentration pretreatment. Under extremely constrained land conditions, stacked arrangement of wastewater treatment facilities was designed, providing a reference for similar plant designs.
