Example Embodiment

[0015] Example 1

[0016] A Fenton oxidation treatment method for wastewater. The addition amount of hydrogen peroxide and ferrous sulfate is determined according to the COD of the wastewater to remove the COD in the wastewater. The specific operation steps are as follows:

[0017] a. Preparations before wastewater treatment: the COD in the wastewater is measured, the amount of COD in the wastewater is 4500mg / L, and the addition amount of hydrogen peroxide is determined according to the measured COD, and then the sulfurous acid is determined according to the addition amount of hydrogen peroxide The amount of iron added, where the ratio of the quality of hydrogen peroxide to the COD in the wastewater is 1:1, and the volume ratio of the added amount of ferrous sulfate to the added amount of hydrogen peroxide is 3:1;

[0018] b. Wastewater treatment: pass the waste water into the waste water treatment container with a flow rate of 1t / h, and then pass sulfuric acid solution into the wast...

[0019] Example 2

[0020] A Fenton oxidation treatment method for wastewater. The addition amount of hydrogen peroxide and ferrous sulfate is determined according to the COD of the wastewater to remove the COD in the wastewater. The specific operation steps are as follows:

[0021] a. Preparatory work before wastewater treatment: Measure the COD in the wastewater. The measured COD amount in the wastewater is 6800mg / L, and the addition amount of hydrogen peroxide is determined according to the measured COD, and then the sulfurous acid is determined according to the addition amount of hydrogen peroxide. The amount of iron added, where the ratio of the quality of hydrogen peroxide to the COD in the wastewater is 1:1, and the volume ratio of the added amount of ferrous sulfate to the added amount of hydrogen peroxide is 3:1;

[0022] b. Wastewater treatment: pass the waste water into the waste water treatment container with a flow rate of 1t / h, and then pass sulfuric acid solution into t...

Abstract

The invention discloses a Fenton oxidation treatment method for wastewater. The addition of hydrogen peroxide and ferrous sulphate can be determined to remove COD in wastewater according to the COD ofthe wastewater. The advantages of the method are as follows: the removing rate of the COD in the wastewater can reach more than 80% by determining the addition of the hydrogen peroxide and the ferrous sulphate according to the COD of the wastewater, so that high removing rate of the COD of the wastewater can be achieved; and the method is low in hydrogen peroxide and ferrous sulphate price, abundant in source and low wastewater treatment cost.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a Fenton oxidation treatment method for wastewater. Background technique [0002] Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in a water sample. The oxygen equivalent of substances (generally organic matter) that can be oxidized by strong oxidants in wastewater, wastewater treatment plant effluent and polluted water. In the study of river pollution and industrial wastewater properties and the operation and management of wastewater treatment plants, it is an important and quickly determined organic pollution parameter. The existing wastewater treatment process has a low removal rate of COD in wastewater. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a Fenton oxidation treatment method for wastewater. [0004] The technica...
