A Case Study of Dyestuff Chemical Wastewater Treatment Project

Abstract

The wastewater treatment engineering design scale of a certain dye group co., LTD in Xuzhou is 3000m 3/d, According to the characteristics of dyestuff wastewater, the combined treatment process of "physicochemical + biochemical" was adopted. The engineering operation results show that the removal rate of COD, NH3-N and chroma is 93.1, 80.5 and 90.7 percent, and the effluent water quality is stable and meets the design requirements.
