Embodiment 1

[0041] The method that a kind of sulfite composite agent of the present invention activates potassium permanganate to degrade organic matter is applied to process 3mg / L phenol waste water, and its specific steps are as follows:

[0042] (1). Prepare 100mL 80g / L sodium hydroxide solution;

[0043] (2). Prepare 100 mL of magnesium chloride and aluminum chloride mixed solution with a molar ratio of 3:1;

[0044] (3). Stir the mixed solution vigorously, add sodium hydroxide solution into the mixed solution, and continue stirring for 60-120 minutes to obtain a composite solution;

[0045] (4). Heating the above composite solution at a temperature of 65°C for 16 hours, and standing for cooling to obtain a mixed emulsion A;

[0046] (5). Prepare 5mmol / L sodium sulfite solution;

[0047] (6). Prepare 5mmol / L potassium permanganate solution;

[0048] (7). Add 50mL of sodium sulfite solution into the mixed emulsion A, and quickly seal and magnetically stir for 40 minutes at room temp...

Embodiment 2

[0052] This embodiment is basically the same as Embodiment 1, except that the dosage of potassium permanganate solution in the operation step (7) is 25mL, and the reaction is stirred for 30min. After the reaction, the water sample is taken for measurement, wherein the removal rate of phenol is 100%. The concentration of residual sulfate ions was 0.6 mg / L. TOC removal rate is 34% (see figure 1 , figure 2 ).

Embodiment 3

[0054] This embodiment is basically the same as Embodiment 1, except that the dosage of potassium permanganate solution in the operation step (7) is 10mL, the stirring reaction is 30min, and the water sample is taken after the reaction for measurement. Wherein, the removal rate of phenol is 63%. The concentration of residual sulfate ions was 0.5 mg / L. TOC removal rate is 30% (see figure 1 ).

Abstract

The invention provides a method for degrading an organic substance by activating potassium permanganate through a sulfite complex reagent. The sulfite complex reagent comprises emulsion and sulfite-based on the ratio of 20-80 mg / L, wherein the emulsion is prepared by mixing a mixed solution of bivalent metal salt and trivalent metal salt and a base reagent solution.

Description

technical field [0001] The invention belongs to the technical field of drinking water and waste water treatment, and in particular relates to a method for activating potassium permanganate to degrade organic pollutants in water with a compound sulfite agent. Background technique [0002] The removal of organic matter in the field of water treatment has always been a research hotspot. Potassium permanganate, as a powerful oxidizing agent, has the characteristics of low price, environmental protection, wide range of sources, convenient use, easy storage and no toxic and harmful oxidation by-products, and has been widely used. [0003] Potassium permanganate has a strong oxidation ability to pollutants under a wide range of pH conditions, and can selectively oxidize organic matter containing electron-rich groups, and its oxidation product is insoluble and environmentally friendly manganese dioxide. Although potassium permanganate oxidation technology has obvious advantages, co...
