| Abstract: | Aims] New method for the treatment of paraquat wastewater was investigated in this paper.Methods] single factor test were employed to get the optimal condition for the treatment of paraquat wastewater with Tio2-fly ash and fenton reagent.Results] results showed that the optimum condition was as follows: Tio2 was 150 g/l,h2o2 was 5 ml/l,Feso4.7h2o was 300 mg/l,the reaction time was 20 min,the decoloration was 92.23% and the coDcr removal rate was 67.61%.Conclusions] The method had the advantages of high efficiency and easy operation.Therefore,it has a good prospect for practical application. |
