Abstract
In response to the challenges of high concentrations of refractory organic compounds in printing and dyeing wastewater and the difficulty in meeting discharge standards through traditional biological treatment methods,this study app-lied a coagulation sedimentation+hydrolysis acidification+aerobic membrane bio-reactor(MBR)process to treat printing and dyeing wastewater of dyeing enterprises in Jiangxi province.The results showed that,the coagulation pre-treatment unit effectively removed suspended solids and a portion of organic matter from the wastewater,achieving removal rates of 93.5％for turbidity and 24.6％for COD.The hydrolytic acidification unit achieved a COD removal rate of 34.0％for the wastewater.The aerobic MBR system,without the addition of ferric chloride,achieved a COD removal efficiency of 70.0％-75.0％for the effluent from the hydrolytic acidification unit.After adding Fe3+(1-2 mg/L)to the aerobic MBR system,the COD removal efficiency increased to 72.5％-78.7％,and the system demonstrated more stable treatment performance.This indicates that the appropriate addition of Fe3+positively contributes to enhancing the removal of organic pollutants in wastewater by the MBR system.This research holds certain reference value for wastewater treatment plants aiming to improve the efficiency of printing and dyeing wastewater treatment.关键词
