Decomposition of selected carbamate herbicides in a constructed wetland system supported by a biopreparation

Year: 2025

Type: article

Abstract: The study aimed to evaluate the effectiveness of a constructed wetland system (CWS) in degrading specific herbicides present in wastewater.To enhance process efficiency, accelerate degradation rates, and reduce the compounds' half-lives in wastewater, a biopreparation was introduced.Conducted on a semi-technical scale, the research compared two CWS systems: one with the biopreparation and one without.The findings demonstrated a high overall efficiency of 96.2%.On the first day, herbicide removal efficiency was 26% in the standard CWS, whereas the system with the biopreparation achieved 41%.By the tenth day, removal efficiency exceeded 90%.The study also determined the DT50 half-life parameters of the herbicides in wastewater and calculated the theoretical time required to reach a concentration of 0.01 mg/dm³.The application of the biopreparation reduced the degradation time of the carbamate herbicide by up to seven days.
