摘      要：The biodegradability of wastewater containing priority pollutant pesticideVydine or triadimenol（C14H18CLN3O2） in different bio-reactor configurations was *** laboratory scale biological reactors were employed：one reactor under aerobic condition and the other under anaerobic *** aerobic reactor was operated at an ambient temperature（22±2） °C,while the anaerobic reactor was run in the lower mesophilic range（30±2） °*** effect of pesticide concentration,hydraulic retention time（HRT） ,and co-substrate on the treatment process was explored,using glucose as a supplemental carbon *** than 96%pesticide was removed after an acclimation period of approximately 172 d（aerobic） and 230 d（anaerobic） .The aerobic reactor achieved complete Vydine utilization at feed concentrations up to 25 mg·L^-1 .On the other hand,the anaerobic reactor was able to degrade 25 mg·L^-1 of ***,glucose was consumed first throughout the experiment in a sequential utilization *** combination of anaerobic and aerobic biological processes yielded higher biomass concentration and lower retention time than individual *** biomass in the combined reactors was first acclimated with the corresponding ***,the target pesticide,at a concentration of 25 mg·L^-1,was sequentially treated in a semi batch mode in the *** studies showed that 24 h HRT of aerobic and 12 h HRT of anaerobic were the optimum combination for the treatment of simulated wastewater containing Vydine,which produced Vydine effluent at concentration below 0.1 mg·L^-1 .The optimum ratio of substrate（Vydine） to co-substrate（glucose） was 1︰100.
