Water environment refers to around people's group space and the water body that can directly or indirectly affect human lives and development, its normal function each
Kind of natural cause and relevant social factor overall, is the important place depended on for existence and development of human society.Along with society and
Expanding economy, the kind of various waste water especially industrial wastewater and discharge increase day by day, and water resource is the most valuable, and lack of water is
Become global problem.Meanwhile, harmful, toxic chemical substance contained in water body, such as benzene homologues, dyestuff, agricultural chemicals and halogen
For hydrocarbon etc., water environment is caused serious harm, in causing world wide, occur in that water quality shortage of water resources widely.Therefore,
Effectively remove all kinds of harmful, the task of top priority that noxious material has become water treatment field.
Advanced treatment of wastewater refers to that municipal sewage or trade effluent, after one-level, two stage treatment, are marks to reach certain reuse
Standard makes sewage be back to produce or the further water treatment procedure of life as water resource.The advanced treating of sewage can reduce pollution
The discharge capacity of thing, can improve again the utilization rate of water resource；Promoting the saving of China's water resource, solution of sewerage advanced treatment process
The predicament that certainly water for industrial use is nervous has far-reaching realistic meaning.

Reason method (adsorb, filter, film process, flocculation sediment etc.), biological method (anaerobism, aerobic, biomembrane etc.), chemistry side
Method (electrochemistry, photochemistry, Fenton's reaction, class Fenton's reaction, ozone oxidation etc.), other method (radiation method, microwave method etc.)；
Wherein purposes is the most extensive, and the most effective is chemical method；Hydroxyl radical free radical (OH) is a kind of important active oxygen, hydroxyl
Free radical has extremely strong electronic capability i.e. oxidability, and oxidizing potential 2.8V, is the oxidation being only second to fluorine in nature
Agent.Carry out depth-averaged model hence with the Strong oxdiative ability of hydroxyl radical free radical and become the main method of advanced treating.Fenton's reaction,
Class Fenton's reaction etc. is to utilize certain catalyst hydrogen peroxide to make it dissociate hydroxyl radical free radical, thus it is organic to play degraded
The effect of thing, but owing to catalysis oxidation needs certain condition, the such as selection of pH, catalyst, catalyst and hydrogen peroxide
The restriction of the factors such as ratio, and its catalytic process can produce mud, thus cause secondary pollution, and be mud after-treatment
Bring difficulty.
Utilize visible light catalytic nano titanium oxide (or its modified material) that the OH of titanium dioxide surface can be adsorbed in-Or H2O
Molecule changes into hydroxyl radical free radical, thus plays organic effect in degradation water；Owing to titanium dioxide can be recycled, due to
There is no the addition of chemical catalyst, because without producing secondary pollution, it is only that the organic matter in water is decomposed into CO2And H2O。
Produce free hydroxyl hence with photocatalysis titanium dioxide and carry out advanced treating, have more market than traditional Fenton class Fenton's reaction
Competitiveness.But it is existing the completeest based on nano titanium oxide band light-catalysed advanced treatment device for industrial wastewater existence process waste water
The most up to standard, photochemical catalyst can not reuse, and causes water process for producing high in cost of production problem.
