Description
Technical field
The invention belongs to water quality cleansing agent manufacture field, specifically, it is related to a kind of tourmaline ceramic load TiO2—NCP
The preparation technology of immobilized photochemical catalyst.
Background technology
With the development of industrial or agricultural, substantial amounts of and ever-increasing HOCs finally necessarily enters the water circulation body of nature
In system, and inevitably appear in drinking water；The particularly abuse of people's veterinary drug thing, electronics and plastic garbage spreads unchecked, and makes
Emerging organic nuisance is continued to bring out in drinking water；High toxicity and extremely strong bioconcentration that they have, even if
Content is atomic, also can constitute great risk to the health of the mankind.The water of indivedual persistence organic pollutants in China, water system
Flat place in the world high-end.
The HOCs in drinking water is thoroughly removed to ensureing that human health is required, the drinking water treatment technique of current China
In, the removing to HOCs is not accounted at all.Generally believe at present：To complicated component in water, the complicated HOCs's of physico-chemical property
Remove, belong to the deep level of processing of drinking water, be very difficult.The adsorption method that some research institutes propose not only can not be thorough by its
Bottom is disposed, and, simply serves the effect of concentration transfer from environment on the whole；The oxidation point that other research institutes use
Solution, it is necessary to which using the extensive strong oxidizer of adaptation, and not only cost is high, operational hazards for strong oxidizer, and is easily caused water
The secondary pollution of body.
Nano-TiO2Crystal is less than under the irradiation of 387.5nm ultraviolet in wavelength as photochemical catalyst, can produce electronics and
Hole pair, i.e. carrier, can make oxygen molecule produce the hydroxyl radical free radical with strong oxidation, and then produce oxidation Decomposition work
With the almost all of difficult organic compound decomposed including bacterium that decomposable asymmetric choice net is contacted finally is allowed to change into
CO2, produce " zero " waste.But, because nano-particle hardly possible is reclaimed, it is impossible to reuse；Photo-generated carrier is easy to again multiple
Close, light-catalysed quantum efficiency is very low；Pure nano-TiO2Catalytic reaction could be triggered by needing the auxiliary of ultraviolet, and actual
Sunray middle-ultraviolet lamp only accounts for 3%~5%, and catalytic decomposition is extremely inefficient, etc. various reasons, makes to seem of great value new
Material is very difficult to apply in the depths reason to HOCs in water.
We are by the nano-TiO of the miscellaneous element of the lot of trace that adulterates2It is supported on the material TCB with natural self-purification ability
On (tourmaline ceramic), TiO has been made2/ TCB composite photo-catalysts, by the catalyticing decomposition action of nano TiO 2 and TCB absorption
Effect and special chemical property are combined, and the decomposition damage capability to HOCs in environment greatly improved, can be visible
Under light, significantly strengthen the decomposition efficiency of photochemical catalytic oxidation, be easy to reclaim again and use for a long time.It is demonstrated experimentally that applied in water
Micro HOCs depths reason, is a kind of deep processing method close to natural auto purification.
