Abstract: In this study, electrolytic enhanced constructed wetland technology is proposed, and the purifica-tion mechanism of low pollution water is studied at low temperature. Through the setting of low- temperature conditions, the optimization of HRT parameters of electrolytic enhanced constructed wetland and the optimization of simulated influent concentration, a small-scale constructed wet-land test device is constructed. Under the action mechanism of plant microorganism electrochem-ical combined treatment of low pollution water nitrate nitrogen, orthophosphate and sulfametho- xazole, the stable purification effect of electrolytic enhanced constructed wetland on sulfametho- xazole under low-temperature conditions is achieved. The research shows that under the treatment of electrolytic enhanced electrolytic constructed wetland, the treatment effect of various pollutants in low pollution water reaches a good treatment effect, and the removal of pollutants in low pollution water at low temperature is also realized, and the removal effect reaches a high level.
