Description
Technical field
The present invention relates to sewage treatment area, especially for a kind of novel C OD degradation agents of paper waste.
Background technology
As World Economics and industrialized process, the demand to water are being constantly increasing, the thing followed is waste water
Discharge capacity it is also increasing, discharge standard is also more and more stricter.Paper waste is made essentially from pulp mill, paper mill, slurrying
The industrial department such as paper integrated complex and some papermaking processing enterprises.The wastewater discharge of papermaking enterprise is big, and the concentration of organic matter is high,
The biochemical of waste water is poor, and the extensive concern of domestic and international various circles of society is caused all the more.Give up in the stage casing for for example in pulping process producing
Water, its COD is at concentrations up to 5000-20000mg/L.Therefore, the COD degradation in paper waste is treated as the important of wastewater treatment
One ring.
Paper waste mainly contains tiny suspension fiber, papermaking filler, waste paper impurity and a small amount of pectin, wax, carbohydrate, with
And all kinds of organic and inorganic compound added in paper-making process.It is solid removal that such waste water recycling needs the subject matter for solving
Body suspension and COD.
At present, the processing method of paper waste COD mainly has three kinds；
(1) absorption methods removal COD：Can be by activated carbon, macroreticular resin, bentonite isoreactivity sorbing material, at absorption
Particulate organic matter, colourity in reason sewage, this method can only reduce the COD for being easier treatment primarily as pre-treatment；
(2) microbial methods removal COD：Bioanalysis is aoxidized or reduces organic molecule by microbial enzyme, destroys it not
Saturated bond and chromophoric group, so as to reach a kind of method of wastewater treatment of processing intent.Because microbial reproduction speed is fast, adaptation
Property is strong, with low cost, is widely used in the treatment of kiering waste water in recent years.But due to high effective microbial community
Particularity, it is preserved and application all receives substantial amounts of limitation, and is easily lost activity in application high-effective microorganism, when
When the variation water quality of waste water is larger, it is difficult to adapt to, high-effective microorganism substantially is added daily now, can just play corresponding
Effect, but treatment effeciency is still limited.The equipment and reparation technology of high-effective microorganism are cultivated simultaneously costly, cause it
That applies is relatively costly, is not easy to be promoted in enterprise；
(3) chemical process to remove COD：Using the oxidation decomposing organic matter of chemical agent, dioxygen is typically used at present
The hazardous chemicals such as water, the concentrated sulfuric acid are aoxidized, are catalyzed, and not only COD clearances are low, sinking speed slow, may introduce new dirt
Dye thing component, and there is security risk during transport and use.
The content of the invention
The technical problems to be solved by the invention are to overcome deficiency of the prior art, there is provided a kind of novel C OD drops
Solution agent, high to COD clearances, sinking speed is fast, and dehydrating effect is good, without changing technique and increase equipment, it is only necessary to set one
Individual chemical feeding points, simple to operate according to the percentage of each material of actual water quality situation scene adjustment, dehydration property is good, and not
New contaminant component can be introduced, instead of hazardous chemical, it is to avoid security risk.
The purpose of the present invention is achieved through the following technical solutions：A kind of novel C OD degradation agents, including machine aluminium or nothing
Machine iron coagulant HD-C3, ferrous complex salt HD-C4, strong oxidizer HD-C5 three compounding are formed, and each material accounts for total matter after compounding
The percentage of amount is respectively：Inorganic aluminum or inorganic iron coagulant HD-C3 contents are 70%-80%, ferrous complex salt HD-C4 contents
It is 10%-20%, strong oxidizer HD-C5 contents are 5%-10%.
Strong oxidizer HD-C5 decomposes generation hydroxyl radical free radical and active oxygen certainly under ferrous complex salt HD-C4 catalytic action
By base, its oxidizing potential can reach 2.8V, and oxidation operation is resolved into small molecule by it by approach such as electro transfers.Meanwhile,
Under inorganic aluminum or inorganic iron coagulant HD-C3 synergies, part Fe2+ is oxidized to Fe3+ and hydrolysis occurs and produces in HD-C4
Raw coagulating sedimentation, removes large amount of organic
Preferably, a kind of novel C OD degradation agents, the percentage that each material accounts for gross mass after compounding is respectively：It is inorganic
The content of aluminium or inorganic iron coagulant HD-C3 is 70%, and the content of ferrous complex salt HD-C4 is 20%, and strong oxidizer HD-C5 contains
Measure is 10%.
Preferably, a kind of novel C OD degradation agents, the percentage that each material accounts for gross mass after compounding is respectively：It is inorganic
The content of aluminium or inorganic iron coagulant HD-C3 is 77%, and the content of ferrous complex salt HD-C4 is 15%, and strong oxidizer HD-C5 contains
Measure is 8%.
Preferably, a kind of novel C OD degradation agents, the percentage that each material accounts for gross mass after compounding is respectively：It is inorganic
The content of aluminium or inorganic iron coagulant HD-C3 is 85%, and the content of ferrous complex salt HD-C4 is 10%, and strong oxidizer HD-C5 contains
Measure is 5%.
Preferably, a kind of novel C OD degradation agents, wherein strong oxidizer HD-C5 is powdery or lenticular.
Beneficial effects of the present invention are：
(1) COD clearances are high；
(2) sinking speed is fast；
(3) good decolorizing effect；
(4) need not change technique and increase equipment, it is only necessary to which a chemical feeding points are set, is adjusted according to actual water quality situation scene
The percentage of whole each material, operation sequence is simple；
(5) dehydration property is good, can substantially reduce specific resistance to filtration expense；
(6) non-secondary pollution；
(7) instead of hazardous chemical, it is to avoid transport and use security risk present in process.
Specific embodiment
