Description
Technical field
The present invention relates to a kind of preparation method of the silicon substrate flocculant for thering is class Fenton to act on, belong to high concentrations of organic dye dirty
Water-treatment technology field.
Technical background
In recent years, the dye wastewater of dye industry discharge has become the subject matter in modern industry, these dyestuffs master
Be used to weaving, print and dye, papermaking, process hides, in the industrial sector such as paint.Based on dye wastewater complicated component, toxicity is high, colourity
Greatly, it is anti-oxidant, the characteristics of antibiont degradation capability is strong, and a large amount of situations about using of dyestuff cause dye wastewater discharge capacity big
So as to cause serious problem of environmental pollution.In traditional Fenton oxidation course of reaction, ferrous ion attacks hydrogen peroxide point
Son hydroxyl radical free radical of the generation with strong oxidizing property realizes organic pollution oxidation Decomposition, ferrous ion be oxidized to form iron from
Son.Fast with reaction speed, oxidation rate is high, simple to operate, easy realization, to the organic pollution degraded substantially without selection
The advantage of property.Its shortcoming is that effective degraded scope of pH is narrower, and iron ion is reduced into the speed of ferrous ion less than ferrous iron
Ion is oxidized the speed of iron ion, and the circulation between the ion of the different valence state of obstruction iron causes the utilization rate of hydrogen peroxide
It is not high, while hydrogen peroxide is extremely easy in decomposition, and then reduce reaction rate.At the same time, the ferric iron that reaction is produced is with the hydrogen of iron
The form of oxide residue is present, and can weaken or block the generation of hydroxyl radical free radical.Using light help Fenton's reaction, flocculation and
During microbial technology combination treatment phenolic waste water, its COD clearance can reach 98.9%, it is shown that very strong synergy
(Chinese patent；Inventor：Liu Guangming, Kong Lingren, Zhong Ping, Zhou Xia, Ren Xuechang, Shi Zaifeng；The patent No.：
CN200410065398.3).But need high light to can be only achieved preferable effect in this method.At using light electrolysis joint Fenton
During reason fracturing wastewater, first there is micro-electrolysis reaction, make substantial amounts of molecular scission in persistent organic pollutants, and produce a large amount of
Fe2+；It is subsequently added hydrogen peroxide and Fenton's reaction occurs, is CO by most of oxidation operation2And H2O；It is subsequently added into polypropylene
Acid amides carries out flocculation sediment, not oxidized pollutant can be separated into (Chinese patent with water；Inventor：Sun Tiegang；Patent
Number：CN201420640558.1).Complex operation in this method, cost is larger, higher to reaction condition requirement.In Fenton reagent
During addition organic additive treatment waste water, the Fe of solubility can be produced in course of reaction3+Part, while effective pH scopes are widened,
Have the disadvantage that the organic additive for adding does not have reducing power, it is impossible to strengthen Fe2+With Fe3+Between circular response, it is possible to decrease reaction
Efficiency (Abida O, Mailhot G, Litter M, Bolte M；Impact of iron‐complex(Fe(III)‐NTA)
on photoinduced degradation of 4‐chlorophenol in aqueous solution).In order to overcome with
Upper shortcoming, class Fenton oxidation reaction receives extensive concern as effective and efficient technology.
