Description

Fenton reagent oxidized waste water processing method and processing device
Technical field
The invention belongs to technical field of waste water processing, and in particular to a kind of Fenton reagent oxidized waste water processing method and processing device.
Background technology
Increasingly raising and industrial rapid development with human living standard, accordingly produce increasing municipal wastewater and Industrial wastewater.Wherein biochemical waste water is handled by bioanalysis mostly at present, contains hardly degraded organic substance and poisonous and harmful The waste water of material, such as medicine, petrochemical industry, printing and dyeing, the waste water of papermaking industry have that discharge capacity is big, pollution is wide, can give birth to The characteristics of property changed difference, conventional physics, chemistry, biological method is caused to be difficult to meet the requirement of purified treatment technically and economically, As the problem of field of water pollution control.However, the problem of in face of water resources shortage and water pollution aggravation, country and local government Tightened up control standard is proposed to industrial enterprise's draining, some areas even require the control of draining COD concentration in 50mg/L Below.Therefore, the efficient control bio-refractory organic pollution of research and development, the water process new technology of discharged wastewater met the national standard and new is realized Equipment turns into the focus studied both at home and abroad.
High-level oxidation technology has the incomparable advantage such as bioanalysis and Physical in wastewater treatment, in advanced treatment of industrial waste water As study hotspot, especially Fenton reagent oxidation technology due to having the characteristics that degree for the treatment of is deep, adapting to that waste water is strong to enjoy pass Note.Fenton reagent oxidation technology principle is that oxidant H is added in waste water2O2And catalyst Fe2+, H2O2In Fe2+Catalysis Effect is lower to decompose the hydroxyl radical free radical (OH) for having high reaction activity, and it is by approach such as electronics transfers by useless Organic substance in water Oxidation Decomposition is into small molecule, CO2And H2O2, so as to reach degraded COD purpose.
Use Fenton reagent oxidation technology processing waste water general step for:First by the pH value of waste water regulation to 3.0 or so, then Quantitative hydrogen peroxide and ferrous salt are added, the pH value of waste water is pulled back to neutrality by hybrid reaction afterwards for a period of time, subsequently into heavy Shallow lake pond carries out mud-water separation.But because the complicated component of waste water is various, and same waste water is in different time sections content of organics The factor such as change cause existing Fenton reagent oxidation technology and device to have the disadvantage that in actual applications:
1. the pH value control of pair oxidation water inlet is not accurate enough.It is Fenton reagent technique that the pH of control waste water, which is in a suitable value, The most important condition of oxidized waste water, but some waste water to pH value regulation due to containing higher carbonate basicity, playing slow The effect of punching, cause in a short time to be difficult to the pH regulations of waste water to suitable value;And due to being given up caused by process units Alkalinity of water changes greatly sometimes, so there is phenomenon fluctuated in the pH that constant acid adding amount can cause oxidation to be intake, so as to Influence the treatment effect of Fenton reagent oxidation.For the waste water of same basicity, pH value has one and declined suddenly after acid adding " catastrophe point ", this is due to that basicity in water is neutralized the reason for can not playing " buffering " by complete acid, is continuing with concentrated acid and adjusts PH value has larger difficulty.So regulation of the Fenton oxidation technique to pH value in practical application in industry is difficult to accurately, cause Treatment effect declines.
2. the chemical feeding quantity control of pair oxidant is not accurate enough.The dosage of oxidant is according in waste water in Fenton reagent oxidation technology Come what is determined, content of organics, which has, in the waste water continuously generated due to process units becomes by content of organics and the COD of oxidation water outlet Change characteristic, when the COD for aoxidizing water outlet meets standard, the dosage of oxidant needs to contain according to aoxidizing into Organic substance in water at any time The change of amount and change, just can guarantee that the dosage of oxidant is in desired value.Constant basis is selected to add oxidant in legacy devices Mode, it is unstable to not only result in water outlet COD, and it is excessive sometimes add, cause medicament to waste, can also make water outlet COD detection is affected (remaining hydrogen peroxide can influence on COD detection band in water outlet).
3. complex process, operation difficulty intensity are big.Fenton reagent oxidation technology is complicated, and is needed during influent quality fluctuation timely Acid adding amount, caustic dosage and added amount of chemical are adjusted, and process adjustments often lag behind change of water quality, so operation is difficult Degree and intensity are larger, and the technique is mostly run using " extensive style " of constant dosing in actual applications, and not only treatment effect is not It is stable, and a large amount of medicaments are wasted, add processing cost.

Compared with the present invention, the Patents do not carry out 2 grades of regulations of fine tuning after first coarse adjustment to wastewater pH regulation, in reaction PH control accuracies it is inadequate;Patents control H by the oxidation-reduction potential of waste water in oxidation reaction pond2O2Dosage, Because waste component is complicated, the oxidation-reduction potential of waste water can not accurately reflect total amount of organic, so by oxidation reaction pond The oxidation-reduction potential of waste water controls H2O2Larger error be present in dosage.And the present invention passes through on-line checking flow of inlet water simultaneously The method that total amount of organic in waste water is obtained with influent COD controls H2O2Dosage is more accurate, and treatment effect is more stable, Processing cost is lower.
Patents CN 101525190 (a kind of efficient wastewater treating process based on Fenton's reaction) discloses one kind and is based on Fenton The efficient wastewater treating process of reaction, comprises the following steps:3-5 is arrived into the pH value regulation of pending waste water;Add H2O2, Mix;FeSO is added in batches4·7H2O, and FeSO is added every time4·7H2Accessing pending water PH regulations are arrived before O 3-5, FeSO has been added every time4·7H23-10 minutes are stirred after O;7.5-8 is arrived into the PH regulations of waste water after processing;Add wadding Solidifying agent, removes coagulative precipitation thing.According to waste water situation, the present invention realizes quantification chemical feeding quantity, and solution medicament is insufficient or excessive shadow The problem of ringing treatment effect;Ferrous salt adds in batches, improves its service efficiency, reduces the dosage and sludge quantity of medicament;Without H2O2 Residual, reduce processing residual H2O2Processing step;H is added portionwise2O2With hydroxyl radical free radical caused by control system moment Amount, effectively handles high COD, organic wastewater with difficult degradation thereby.
Compared with the present invention, the Patents are different not according to pending kind of waste water and the pH of reaction is accurately controlled, Reaction effect is poor;The Patents make oxidation reaction thorough, but do not consider by adding oxidant and catalyst in batches Oxidant and catalyst are added by the total amount of organic in waste water, as waste water quality and water change greatly, then treatment effect It is unstable.
