Abstract
The treatment of printing and dyeing wastewater faces challenges including high chromaticity,high salinity,and refractory organic compounds.A three-stage integrated process combining ultrafiltration,het-erogeneous Fenton oxidation,and nanofiltration(MS-AOPs)was employed.The results demonstrated:ultrafil-tration achieved 98.6%suspended solids removal;heterogeneous Fenton oxidation at pH 3 with H2O2/Fe3+mo-lar ratio of 10∶1 removed 85.2%COD and completely decolorized the wastewater within 60 min;nanofiltration reduced TDS from 4 200 mg/L to 180 mg/L,meeting the reuse criteria of the"Discharge standards of water pollutants for dyeing and finishing of textile industry"(GB 4287-2012).The operational cost was 2.8 RMB/t,representing a 30%reduction compared to conventional methods,with catalyst reusability exceeding 5 cycles.This process provides a feasible solution for low-carbon and high-efficiency treatment of printing and dyeing wastewater.关键词
