Abstract
With the development of industry, the treatment of chemical wastewater has become an important environmental protection issue. Traditional treatment technologies suffer from low efficiency, high costs, and secondary pollution problems. Novel membrane separation technologies, characterized by high-efficiency separation performance and operational simplicity, offer new approaches for chemical wastewater treatment. This study aims to investigate the application effects of novel membrane separation technologies in chemical wastewater treatment to provide theoretical basis and technical support for practical engineering applications. Representative nanofiltration membranes, forward osmosis membranes, and ceramic membranes were selected as research subjects. By combining laboratory simulation experiments with on-site pilot tests, the removal efficiencies of typical pollutants and operational stability of different membrane materials were examined. The results indicate that nanofiltration membranes exhibit good retention rates for organic compounds and multivalent ions, forward osmosis membranes achieve low-energy-consumption concentration separation, and ceramic membranes demonstrate excellent anti-fouling properties and long service life. Innovatively coupling multiple membrane processes to construct an integrated membrane system significantly improved wastewater treatment efficiency and water quality compliance rates while reducing treatment costs. The study demonstrates that novel membrane separation technologies hold broad application prospects in the field of chemical wastewater treatment, providing effective solutions to water pollution problems in the chemical industry and promoting the development of green chemistry..
