At present, substantial amounts of water is used for cleaning and dyeing.At the same time, the soil of modern industry activity also to the whole world
Extensive dangerous contamination is caused with water.The most troublesome pollutant of one type is persistence organic pollutant (POPs), is such as contaminated
Material, detergent and agricultural chemicals.Due to its water-soluble and chemical stability, the presence of these colored compounds in the environment can cause phase
When many pollutions and serious health risk problem.Organic dyestuff is in weaving, papermaking, pigment, food, cosmetics, medicine manufacture
Cause serious environmental hazard etc. widely using in industry and carelessly processing.
Dyestuff discharge industry mainly cause the pollution of water and the health problem to PE health because some dyestuffs and
Its metabolite is poisonous, carcinogenic, teratogenesis and mutagenesis.Therefore, dyestuff is removed from waste water significant.Due to traditional
Sewage water treatment method can not effectively eliminate these pollutants, so strong purification method of the research for waste water from dyestuff,
Receive more and more attention.
In past decades, the processing of textile printing and dyeing wastewater has color deep, and biological degradability is low and the spy such as toxicity height
Point is always the subject matter of environmental protection.Rhodamine B (Rhodamine B) is a kind of nitrogenous dyestuff, is detested self by reduction
Oxygen degraded may produce potential carcinogenic aromatic amine.And traditional biological process of wastewater treatment can not effectively remove rhodamine B
(Rh B)。
Existing biodegrading process is mainly Physical, chemical method, physical-chemical process and microbial method.But apply these
There are many problems of method still can not solve, such as Physical reproducibility is poor, it is impossible to the colloid and lyophobic dust gone in water removal；Change
Method is to high concentration COD poor processing effect, and power consumption is big, high cost, there is liberation of hydrogen or oxygen uptake reaction；Physical-chemical process is to high concentration
Waste water, high cost；Microbial method there are certain requirements to nutriment, temperature, pH value, and impact resistance is poor, bad adaptability, reaction
Overlong time.In addition, organic dyestuff is in progressively decomposable process, the intermediate material of generation is more harmful than itself.Therefore, develop
It is very necessary that new technology or improvement old technology, which are handled,.
The content of the invention
In order to solve problem above, the present invention provides a kind of degradation rate soon, low cost, without intermediate product generation and not
The ferrite of secondary pollution can be caused to coat sepiolite composite catalyst.
