Research of the application of Fenton oxidation to the treatment of wastewater containing urotropine
Online published: 2010-10-01
The reaction condition has been optimized through experiments for the oxidation of wastewater containing urotropine by Fenton reagent. It is indicated that when ρ(H2O2) = 8.25 g/L, n(H2O2) ∶ n(Fe) = 20 ∶ 1, pH = 3.0, CODCr may be decreased from 1 250 mg/L to lower than 100 mg /L after 5 h reaction under 35 ℃. But it is difficult for CODCr to reach 100 mg /L when the temperature dropped to 15 ℃. It is also suggested that CODCr of the effluent from CSTR(continuous-flow stirred tank reactor) is significantly higher than that from SBR(sequnencing batch reactor) under the same condition.
