| description | The invention discloses a method for verifying the addition amount of hydrogen peroxide for treating nitro-oxidant wastewater. The method comprises the following steps: preparing a plurality of groupsof nitro-oxidant wastewater solutions; calculating the theoretical volume addition amounts of calibrated H2O2, respectively adding H2O2 with the addition amount increased progressively in a gradientmanner into each group of solution, and setting a blank control group; measuring and calculating the concentration of nitrate nitrogen, the concentration of nitrite nitrogen and the concentration of nitrous acid in the six groups of wastewater before neutralization, and the concentration of nitrate nitrogen and the concentration of nitrite nitrogen in the neutralized wastewater by adopting a spectrophotometric method; drawing a corresponding curve graph according to measured data, and respectively calculating the ionization degree of nitrous acid in the six groups of wastewater before neutralization, the removal rate o |
