Abstract
Implementations herein relate to systems and methods for removal of tebuconazole from water using a duplex reactor. Water samples containing tebuconazole enter a double sandwich of the duplex reactor, and then enter a reactor inner shell of the duplex reactor through a water distributor. In the duplex reactor, the tebuconazole is removed by adsorption resins loaded with microorganisms. After the removal, a concentration of the tebuconazole in adsorption effluent is below the standard limit of the national pesticide wastewater discharge. The microorganisms loaded on the resins use organic carbon (e.g., tebuconazole) in water as a carbon source and degrade tebuconazole that is absorbed by the resins. The systems and methods not only solve problems associated with conventional techniques (e.g., poor water quality fluctuations and lacking of time long degradation), but also address issues associated with resin adsorption methods (e.g., secondary pollution derived from resins regeneration).
