【Abstract】

[Objectives]To treat pig farm wastewater and solve the problem of pollution caused by it to surface water or groundwater. [Methods] Fe and Zn/biochar( AC) was prepared by dipping method using pig manure-derived biochar as carrier. The preparation conditions were investigated,and the screened metal-loaded biochar was characterized. Pig farm waste water was treated with metal-loaded biochar-H_2O_2 catalytic oxidation method. [Results]At the COD concentration of 2 904 mg/L,0. 02 g Zn/AC and 0. 005 mL H_2O_2 showed the highest COD removal rate( qe) from pig breeding wastewater under conditions of reaction time of 8 h,pH value of 7 and temperature of 55 ℃,reaching 70. 98%. [Conclusions]Fe or Zn-loaded biochar made from pig manure-derived activated carbon has a certain catalytic capacity for the actual oxidation treatment of pig farm wastewater. The activity of Zn/AC was higher,and its COD removal rate from pig farm wastewater was also higher.
