Description
Technical field
The invention belongs to environmental technology fields, are related to a kind of method of Electrocatalytic Oxidation processing Polyester wastewater.
Background technique
Polyester wastewater basic component is that the incomplete raw material of reaction includes glycerol, pentaerythrite, propylene glycol, styrene, third
Alkene nitrile, ethylene oxide, propylene oxide and salt include the groups such as low molecule polymerized monomer and high molecular polyether there are also side reaction product
At.Wherein react incomplete raw material such as glycerol, pentaerythrite, propylene glycol, styrene, ethylene oxide, propylene oxide etc. all easily
Biochemistry, it is biodegradable, but its side reaction product low molecule polymerized monomer and high molecular polyether biodegradability are poor, belong to difficult to degrade
Substance leads to the BOD of waste water5/CODCrValue is about 0.1-0.3, belongs to waste water difficult for biological degradation.Polyester wastewater processing belongs to typical case
One of difficult organic chemical waste water.
The processing method of general Polyester wastewater mainly has: routine biochemistry method, advanced oxidation processes, combination biochemical method etc..
Routine biochemistry method generally uses biofilter and O/A/O catalytic oxidation combined treatment process, i.e. high concentration production is dirty
Water and low concentration production, sanitary sewage shunt, and high concentration production waste is first pumped into anaerobic biofilter, carries out anaerobic hydrolysis, so
Gravity flow afterwards enters multistage contact-oxidation pool and carries out aerobic (O) biochemical treatment, and after through medium sediment pool carry out mud-water separation, water outlet again with
The low concentration production of remittance, sanitary sewage are mixed into hydrolysis acidification pool and carry out anaerobic hydrolysis (A), subsequently flow into combined sewage and connect
It touches oxidation pond and carries out aerobic (O) biochemical treatment, finally pass through secondary settling tank mud-water separation, water outlet can qualified discharge.Since polyethers is useless
A part of product biodegradability of water is poor, is difficult to reach ideal effect with the method.Advanced oxidation processes are currently used have it is wet
Formula oxidation, photochemical catalytic oxidation, electrochemical process, Fenton reagent oxidizing process method.Wet oxidation process is capable of handling complicated polyethers
Waste water, but need to carry out under the conditions of high temperature (125 DEG C -320 DEG C) and high pressure (0.5MPa-20MPa), so there is investment
Greatly, the disadvantages of operating cost is high；It is both economical, green that photocatalytic oxidation handles Polyester wastewater, but by the limit of turbidity of sewage
System, treatment effeciency is low, and the Polyester wastewater for being suitable for low concentration is handled；Electrochemical process power consumption is higher, and operating cost is high, needs pair
Electrode material etc. is improved；Fenton reagent oxidative treatment effect is preferable, but there are Fe2+And H2O2It is high, sharp to add concentration
With rate problem at high cost caused by low.It combines biochemical method and uses nanofiltration membrane+biochemical treatment group technology: using nanofiltration membrane
Different molecular quality substance is separated, most of macromolecular polyethers in waste water is retained, concentrate COD is about 300g/L, complete
Use can be recycled entirely, and low molecule liquor C OD is about 5000mg/L, with the preferably de- low molecule waste water of biodegradability and low dense
Waste water mixing is spent, anaerobic-aerobic is carried out and combines biochemical treatment, secondary clarifier effluent is using a small amount of pollution of removal after activated carbon adsorption
Object, so as to qualified discharge.But in the method, nanofiltration membrane needs are periodically cleaned or even are replaced, and processing cost is caused to increase.
" research of Fenton- Coagulation with Treatment copolymerization ether wastewater " uses Fenton- Coagulation with Treatment in " applying chemical industry "
It is copolymerized ether wastewater, with FeCl3For coagulant, under certain condition, the COD removal rate of waste water can reach 58.7%, and chromatic value is low
In 10 degree.Although the method solves effluent color dilution and suspended matter caused by the gelatinous ferric hydroxide that it is generated after Fenton reacts
The high problem of content, but the biodegradability of waste water is not studied.In " Treatment of Industrial Water " " at light electrolysis-Fenton method
Manage star copolymerization ether wastewater research " using light electrolysis-Fenton combination method to the waste water in star copolyether synthesis process into
Row processing.By iron carbon ratio, 30%H in experimental study2O2Input amount, reaction time, initial pH are investigated, under certain condition,
Handled wastewater COD removal rate can reach 92.9%, and waste water COD is reduced to 260mg/L.But it is micro- without carrying out iron carbon in document
The life experiment of electrolysis, therefore this method is only limitted to the laboratory research stage." UV-Fenton in " industry security and environmental protection "
Oxidation pre-treatment Polyester wastewater research " has inquired into H by orthogonal experiment2O2Dosage, Fe2+Dosage, pH value and light application time
Influence of each factor to wastewater COD removal rate, under optimum reaction condition, COD removal rate is aoxidized pre- place up to 70% or more
The B/C value of waste water is improved by 0.19 to 0.37 after reason, and biodegradability improves a lot, but this processing method need illumination and and
Oxidant is just able to achieve, higher cost.
Electrocatalytic Oxidation is by the direct degradation of organic substances of anode reaction.Some document reports utilize electrocatalytic oxidation
Method Phenol-Containing Wastewater Treatment, methyl orange aqueous solution waste water, phenol-acetone waste water, coking wastewater etc., treatment effect is obvious.But electricity is urged
A kind of method changed oxidative treatment waste water higher cost, therefore to seek high-efficiency and economic becomes the research and development of electro-catalytic oxidation technology
Emphasis.
