In recent decades, much research is carried out on the treatment of refractory organic wastewater at home and abroad, wherein the oxidation method is made out of consideration in research and application by the huge potential and unique advantages of the oxidation method. Compared with other traditional water treatment methods, the oxidation method has the following characteristics:
① generates a large amount of very active hydroxyl free radicals OH which have strong oxidizing power (2.80V) next to fluorine (2.87V) and can induce a series of chain reactions later as intermediate products of the reaction;
② because it is a physical-chemical process, it can be easily controlled to meet the treatment needs and even degrade 10-9mg/L level contaminants, such as pre-treatment or deep treatment for biochemical treatment, to reduce the treatment cost.
The currently used advanced oxidation methods mainly include the following:

However, most of these methods degrade general organic substances or specific organic substances, and do not have a significant effect on organic substances having complicated components.
Therefore, the application provides a method for degrading complex organic matters in wastewater by using a white light irradiation assisted ferrous oxidation method, wherein ferrous/H is used under the white light irradiation2O2The oxidation degrades the organic matters with complex components, so that the oxidation efficiency is greatly improved, the degradation of the organic matters in the wastewater is promoted, and the mineralization degree of the organic matters is more sufficient.
Disclosure of Invention
The invention mainly aims to provide a method for degrading complex organic matters in wastewater by using a white light irradiation auxiliary ferrous oxidation method, which can effectively solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: a method for degrading complex organic matters in wastewater by using a white light irradiation auxiliary ferrous oxidation method comprises the steps of adding hydrogen peroxide and an oxidant into the wastewater containing the complex organic matters, simultaneously irradiating the wastewater by using white light, and rapidly stirring, wherein the oxidant is ferrous ions.
Preferably, the dosage of the hydrogen peroxide in each liter of wastewater is 2-18 mL.
Preferably, the amount of the oxidant used is 0.5-2.5mL per liter of wastewater.
Preferably, the reaction temperature of the wastewater is 40-80 ℃, and the pH value of the wastewater is 2-5.
Preferably, the irradiation time of the white light is 1-6 min.
1、Fe2+/H2O2Principle of method
Fe2+/H2O2This process has been found to have been in the past for over 100 years, but its application as an oxidation process for the removal of organic contaminants began in the 60's of the 20 th century. First of all using Fe2+/H2O2The system research treats phenol wastewater and alkylbenzene wastewater. Thereafter, the research in organic wastewater treatment should be conductedUse is increasingly gaining importance. The action mechanism is as follows:
Fe2++H2O2→Fe3++·OH+OH-
this process, which destroys organic substances in the dark, has the advantage of saving on equipment investment, but has the disadvantage that the organic substances are not sufficiently mineralized first, the initial reactants are converted into certain intermediates, which are reacted with Fe or with them3+Complex formation or competition with the generation route of OH can cause more environmental hazard; second pair of H2O2The utilization rate of the process is not high.
The influence of pH on the OH formation rate is mainly shown by Fe when pH is too high2+Catalysis H2O2The rate of decomposition decreases, the rate of formation of OH decreases, and H is present under alkaline conditions2O2Self-decomposition also occurs, which is also disadvantageous in the formation of. OH. The pH value is 2-5, which is most favorable for generation of OH. The reaction temperature has a small influence on the apparent OH formation rate, and it is considered that the OH formation is mainly diffusion-controlled.
2. Introducing a white light auxiliary action principle:
introducing white light into Fe2+/H2O2System, forming white light/Fe2+/H2O2Method, substantially of Fe2+/H2O2And white light/H2O2The combination of the two systems has the following advantages:
① can reduce Fe2+In an amount of (1), maintaining H2O2The utilization rate is high;
② white light and Fe2+To H2O2The catalytic decomposition has synergistic effect, and H in the system2O2Has a decomposition rate much greater than that of Fe2+Catalysis H2O2Simple addition of decomposition rates, mainly due to Fe2+Some of the hydroxyl complexes of (a) can be caused by a photosensitization reaction to generate OH;
③ can make the mineralization of organic matter more complete because of Fe3+Formed with intermediate products produced during degradation of organic matterThe complex is an optically active substance and can be degraded continuously under the irradiation of white light;
④ organic matter may be partially decomposed under white light illumination.
The method has strong oxidizing power, can effectively decompose organic matters, and has good mineralization degree, but the method is only suitable for treating organic wastewater with medium and low concentration. This is because when the organic concentration is high, the number of photons absorbed by the Fe (III) complex is small, a long irradiation time is required, and H is2O2The amount of the catalyst to be added is also increased, and OH is liable to be contained in H at a high concentration2O2And (4) clearing.
The key point for improving the treatment efficiency of the organic wastewater is to improve the generation rate and the utilization rate of OH in a reaction system. Research shows that Fe2+Concentration, H2O2Both the concentration and the pH value influence the OH formation rate. In a certain concentration range, with Fe2+And H2O2The concentration increases, so does the apparent OH formation rate; but when Fe2+Or H2O2When the concentration is too high, the apparent generation rate of OH is rather lowered, and this phenomenon may be caused by the following reasons:
(1)Fe2+capture for. OH:
Fe2++·OH→Fe3++OH-
(2)H2O2capture for. OH:
H2O2+·OH→HO2·+H2O
(3) self-reaction of OH
·OH+·OH→2H2O+O2
So that a part of the initially produced OH is consumed and the apparent OH formation rate is reduced.
Therefore, Fe is not increased2+And H2O2Under the condition of concentration, white light is used for auxiliary irradiation, so that the quantity of OH is increased, and the oxidation efficiency is greatly improved.
The device specially used for implementing the method for degrading complex organic matters in wastewater by using the white light irradiation auxiliary ferrous oxidation method comprises a reaction container, a stirrer and a light source, wherein the stirrer is positioned in the middle of the reaction container, the light source is positioned inside the reaction container, and the light source is a white light lamp tube.
Preferably, the top of reaction vessel is connected with the tail gas discharge pipe, the top of reaction vessel is connected with the inlet tube that supplies waste water, hydrogen peroxide solution and oxidant to get into, the bottom of reaction vessel is connected with the outlet pipe, one side of reaction vessel is connected with the air intake pipe.
Compared with the prior art, the invention has the following beneficial effects: according to the method for degrading complex organic matters in wastewater by using the white light irradiation auxiliary ferrous oxidation method, the quantity of OH is increased by using white light auxiliary irradiation, so that the oxidation efficiency is greatly improved, the degradation of organic matters in wastewater is promoted, the reduction of the consumption of ferrous ions is facilitated, and the higher utilization rate of hydrogen peroxide is kept; fe3+The complex formed with the intermediate product generated in the organic matter degradation process is an optical active substance and can be continuously degraded under the irradiation of white light, so that the mineralization degree of the organic matter is more sufficient.
