Study on Treatment of the Pesticide Wastewater by the Composite Process of Biological Active Carbon Filter-Fluid Bed

Objective] The research aimed to study treatment effect of the pesticide wastewater by the composite process of biological active carbon filter-fluid bed.Method] The composite process of biological active carbon filter-fluid bed was applied to treat the mixed pesticide wastewater.The removal efficiencies of CODCr,BOD5,NH3-N,SS and the influence factors were investigated.Result] The composite process had good treatment efficiency for the pesticide wastewater.After running stably,the average removal rates of CODCr,BOD5,NH3-N and SS were respectively 91.6%、96.2%、90.2% and 87.5%.All the indices reached the third level criteria specified in Integrated Wastewater Discharge Standard(DB12/356-2008).Conclusion] The whole system operates reliably and simply,and provides a stable,convenient and economical solution for deep treatment of the mixed pesticide wastewater.
