Application of Modified Biochar in the Treatment of Pesticide Wastewater by Constructed Wetland

To explore the synergistic effects of modified biochar in purification herbicide-containing wastewater, effect addition on removal herbicide atrazine wastewater was verified by bags a small reed bed-constructed wetland laboratory. The results showed that sulfuric acid-modified could increase rate from 50% to 70%, and COD elimination 66.7% 86.7%. constructed bed improved efficiency total nitrogen phosphorus outlet water reached Class III level China’s surface quality standard (the inlet inferior V). experimental design met requirements low-cost, generalized atrazine-containing treatment thus have potential for wide application. reflected application as synergist wetlands.
