Abstract
The invention discloses a method for promoting degradation of organic pollutants by coordination of light and inorganic ions. The method sequentially comprises the following steps: adding 0.5-2 g of sodium bisulfite to 1 L of organic wastewater to be treated under illumination of 180-300 W xenon lamp; then adding 0.3-1 g of iron trioxide, stirring for 10-20 min; precipitating and separating to remove organic matters in the water to be treated. The method is simple and effective, and can quickly remove pollutants in the water.
Description
Technical field
The invention belongs to a kind of method that sewage treatment area, light and inorganic ionss collaboration promote organic pollutant degradation,
Can be applicable to treatment of domestic sewage advanced and Industrial Wastewater Treatment.
Background technology
The most frequently used bioanalysises of current wastewater treatment are poor to biodegradability, the material that relative molecular mass is from thousand of to tens of thousands of
Process more difficult, and chemical oxidation can improve the biodegradability of the pollutant by its direct mineralising or by Oxidation, together
When also have very big advantage to the process of the micro harmful chemical such as Environmental estrogen aspect.Chemical oxidization method is using chemistry
The strong oxidizing property of oxidant, by the small-molecule substance into nontoxic with Organic substance exhaustive oxidation of the inorganic matters in waste water or gas, from
And reach the purpose of process.Common chemical oxidizing agent is O3、H2O2、ClO2And K2FeO4Deng these oxidants are under normal circumstances
All it is strong oxidizer, Some Organic Pollutants can be aoxidized in the solution.However, it is strong and have a choosing but to yet suffer from oxidability
The shortcomings of selecting property, it is difficult to meet and require.
Iron oxides mainly include the hydroxide of ferrum and the oxide of ferrum, in being widely present in natural environment.Wherein, three
Two ferrum etc. are aoxidized due to cheap and easy to get, and with more stable physicochemical properties, by the extensive concern of researcher.Traditional
Ferrum oxide catalysis needs to be aided with purpose of the oxidizing substances such as hydrogen peroxide, ozone to reach catalytic degradation organic pollution.Oxidation
Agent consumes larger, and degradation speed is slow, it is impossible to meets industry degraded and requires.
The content of the invention
The purpose of the present invention be to overcome the shortcomings of prior art in ferrum oxide catalyzing and degrading pollutant, there is provided a kind of light and
The method that inorganic ionss collaboration promotes organic pollutant degradation.
The invention provides technical scheme below, a kind of light and inorganic ionss collaboration promote the side of organic pollutant degradation
Method, in turn includes the following steps：
Under 180~300W Xenon light shinings, 0.5~2g sodium sulfitees are added in 1L pending organic wastewater, then
0.3~1g iron sesquioxide is added, 10~20min, precipitate and separate, you can by the organic matter removal in accessing pending water is stirred.
The method is reacted using sodium sulfite with iron sesquioxide, and high active substance is produced rapidly, is realized to having in water
The quick removal of machine thing, compares iron sesquioxide absorption or processes pollutant, this removal in the case where other oxidizing substances are helped
Speed it is fast and need not consume oxidizing substance.
Compared with existing water process method for oxidation, with following superiority：(1) material used in the present invention is three oxygen
Change two ferrum, be the solid reagent of safety and stability, convenient transportation and cheap, it is not necessary to extra processing unit.(2) inorganic agent
Can reclaim and reuse.(3) reaction condition is gentle, without the need for adjusting pH value.(4) illumination energy-conservation, processing speed is accelerated.
Specific embodiment
Describe the present invention in detail with reference to embodiment, but the present invention is not limited to this.
Embodiment 1
It is that 2g sodium sulfitees are added in 25mg/L methylene blue solutions to 1L concentration under 180~300W Xenon light shinings,
Add 1g iron sesquioxide, stir 10min, precipitate and separate, the clearance of methylene blue is 98.5%, and iron sesquioxide can be with
Recycling.Under the same conditions, if being added without sodium sulfite and illumination, the clearance of Organic substance is 5.2%.
Embodiment 2
It is that 0.5g bisulfites are added in 25mg/L rhodamine B solution to 1L concentration under 180~300W Xenon light shinings
Sodium, adds 0.3g iron sesquioxide, stirs 20min, precipitate and separate, and the clearance of methylene blue is 97.3%, three oxidations two
Ferrum can be reused.Under the same conditions, if being added without sodium sulfite and illumination, the clearance of Organic substance is 5.1%.
Embodiment 3
It is that 1g sodium sulfitees are added in 25mg/L gold orange II solution to 1L concentration under 180~300W Xenon light shinings, then
Addition 1g iron sesquioxide, stirring 15min, precipitate and separate, the clearance of methylene blue is 97.3%, and iron sesquioxide can be again
It is multiple to utilize.Under the same conditions, if being added without sodium sulfite and illumination, the clearance of Organic substance is 4.3%.
Claims (1)
1. a kind of method that light and inorganic ionss collaboration promote organic pollutant degradation, it is characterised in that：Include following step successively
Suddenly：Under 180~300W Xenon light shinings, 0.5~2g sodium sulfitees are added in 1L pending organic wastewater, added
