Description
Technical field
The present invention relates to a kind of while remove sulfur dioxide in flue gas and the method for Organic Pollutants in Wastewater, belong to environment
Protection and technical field of comprehensive utilization.
Background technology
With the fast development of China's industrial or agricultural, water pollution is also on the rise, particularly water body organic contamination, seriously
Influence the water supply security and drinking water quality in China.Organic pollution in water body mainly includes antibiotic, personal care articles, interior
Chaff interferent, pesticide etc. are secreted, there is endocrine disrupting activity and three to cause effect, seriously affect ecological safety and people for these pollutants
Body health.Therefore, there is an urgent need for develop efficiently feasible organic polluting water treatment technology.
Photocatalytic oxidation is the water process new technology just to grow up in recent ten years.Photochemical catalytic oxidation is to various organic
Waste water is respectively provided with good treatment effect, and environmentally friendly, is the processing most promising side of poisonous and harmful organic wastewater
One of method can also be removed effectively many difficult to degrade or toxic had with what other methods were difficult to remove especially with the method
Evil object, such as Polychlorinated biphenyls, perfluorochemical, pesticide, polycyclic aromatic hydrocarbon, dyestuff, pathogenic bacteria (CN101584987B,
CN102107946A、CN101863524B、CN105540730A).Photocatalysis oxidation technique relies primarily on the oxidation of photic generation
Hole and hydroxyl radical free radical (OH) etc. have the active specy oxidative degradation organic pollution of Strong oxdiative ability.However OH etc.
Strong oxidizing property species oxidative degradation pollutant have it is non-selective, which results in during actual waste water is handled, in waste water
Coexisting component, such as Dissolved Organic Matter is easily quenched OH and causes the treatment effeciency of photocatalysis oxidation technique relatively low, influences
Its further promotion and application.
To solve the above problems, the photocatalysis technology based on sulfate radical/inferior sulfate radical free radical is more and more closed
Note.Although the oxidisability of sulfate radical/inferior sulfate radical free radical is slightly less than OH, which contains electron-donating group to many
The reactivity of organic pollution be even higher than OH, and the Coexisting component in water body to sulfate radical/inferior sulfate radical from
It is weaker by the quenching effect of base, ensure that the Css of sulfate radical in photocatalytic system/inferior sulfate radical free radical one compared with
High level, be conducive to strengthen organic pollution oxidative degradation efficiency (CN103979664B, CN103991944A,
CN105174360A、CN105314728A).Sulfate radical/inferior sulfate radical free radical relies primarily on persulfate in photocatalysis at present
Generation is disproportionated under agent existence condition, therefore the photocatalysis technology needs to add a large amount of persulfates, increases operating cost.
Invention content
The present invention is provided for toxic organics in waste water are difficult and the process problem of SO 2 in waste gas
It is a kind of while remove sulfur dioxide in flue gas and the method for Organic Pollutants in Wastewater, pass through the SO in flue gas2Promote photocatalysis
Oxidation technology had both realized the processing of organic wastewater, while SO in flue gas to the removal effect of Organic Pollutants in Wastewater2It obtains
Purification.
It is a kind of while remove sulfur dioxide in flue gas and the method for Organic Pollutants in Wastewater, it is as follows：
（1）Photochemical catalyst is added to be uniformly mixed in the waste water containing organic pollution and obtains mixed aqueous solution system；
（2）Under illumination condition, the exhaust gas containing sulfur dioxide is at the uniform velocity passed into step（1）The mixed aqueous solution system of gained
In, the pH value using basic species control reaction system is 6 ~ 10, and 60 ~ 180min of reaction obtains sulphur removal gas and purified water；
The step（1）In the waste water mesophytization oxygen amount containing organic pollution not higher than 3000mg/L, photochemical catalyst is titanium-based
One kind in catalyst, manganese-based catalyst, bismuth-based catalysts, ferrum-based catalyst, cobalt-base catalyst or arbitrarily than a variety of, basic species
For alkali metal oxide or alkali metal oxide；
Preferably, the photochemical catalyst is TiO2、MnO2、Bi2O3、Fe2O3、Co3O4One kind or arbitrarily than a variety of；
Preferably, the basic species are CaO, Ca (OH)2, NaOH one kind or arbitrarily than a variety of；
In terms of every liter of organic wastewater, the step（1）The addition of middle photochemical catalyst is 100 ~ 800mg；
The step（2）SO in exhaust gas containing sulfur dioxide2Content be 450 ~ 3700mg/L；In terms of every liter of organic wastewater, contain
The intake of the exhaust gas of sulfur dioxide is 0.3 ~ 2.5L.
The beneficial effects of the invention are as follows：
（1）Strong oxidizing property OH that the method for the present invention is generated using photocatalytic process aoxidizes the SO in flue gas2, so as to generate Asia
Potentiometric titrations then by the organic pollution in the oxidative degradation waste water of inferior sulfate radical, realize SO in flue gas2With it is useless
Organic pollutants remove simultaneously；
（2）The technological process of the method for the present invention is simple, it can be achieved that the purpose of the treatment of wastes with processes of wastes against one another.
