Description
Technical field
The present invention relates to a kind of process organic wastewater method.
Background technology
Chemical industry produces every year a large amount of waste water, because its salinity is high, toxicity is big, be difficult to biodegradation and
Become a universally acknowledged difficult problem, serious harm is suffered to ecological environmental and human health impacts, be also me
One of state's pollution most serious, the most intractable industrial wastewater.The method processing organic chemical waste water at present
Have a lot, such as can adopt bioremediation, but poisonous containing suppress growth of microorganism in waste water
Material, then the preferable treatment effect of bioremediation difficult to reach；Aerated micro-electrolysis can also be adopted
Method, Fenton oxidation method, Aerated micro-electrolysis method is carried out in ferrum charcoal reactor, and general process is acid
Waste water, when being immersed in iron particle and charcoal granule in acid waste water, due to the electrode between ferrum and charcoal
Potential difference, can form numerous micro- galvanic element in waste water, the wherein low ferrum of current potential becomes anode, current potential
High charcoal becomes negative electrode, and electrochemical reaction occurs in acid condition.
Aerated micro-electrolysis method has certain process to act on the refractory organic in waste water.Fenton
Oxidizing process then has significant effect for the process of organic wastewater with difficult degradation thereby, adopts in Fenton oxidation method
Fenton reagent is Fe2+And H202, H202In Fe2+Catalytic action under generate there is the hydroxyl of high reaction activity
Base free radical (OH), OH can make it degrade with Organic substance effects most of in waste water, meanwhile, Fe2+
It is oxidized to Fe3+Produce coagulating sedimentation, remove the float in waste water.Base is entered in Fenton oxidation method
Free radical (.OH) is the strongest inorganic oxidizer in addition to element fluorine, can be by Organic substance oxygen most of in waste water
Change and decompose, the effect of therefore Fenton oxidation method process Organic substance is good, but needs in Fenton oxidation method
Fe2+, production cost height.
Content of the invention
In order to solve the problems of the prior art, the invention provides a kind of process organic wastewater method,
And low cost good to treatment of Organic Wastewater effect.
The invention provides a kind of process organic wastewater method, including step：
(1) described waste water is adjusted to pH value between 2.0-4.0；
(2) waste water for 2.0-4.0 for the pH value is reacted by ferrum charcoal with 0.8-1.2 m/h of flow velocity
Device, carries out micro-electrolysis reaction, and adding in described ferrum charcoal reactor has catalyst copper oxide, accelerates ferrum charcoal
Micro-electrolysis reaction；, after processing waste water, the ferrum carbon surface in this reactor can quilt for described ferrum charcoal reactor
Reactant covers, and removes the reactant of this covering, the direction of this backwash by the backwash of gas or water
Contrary with the flow direction of waste water, carry out aeration in this ferrum charcoal reactor simultaneously；
(3) add hydrogen peroxide in the waste water of output, stirring carries out Fenton oxidation reaction；
(4) add lime water through Fenton oxidation in the waste water after processing, the pH value of waste water is adjusted to
8.5-9, is subsequently adding flocculation aid polypropylene look down limb, carries out coagulating sedimentation reaction, obtain supernatant.
As a further improvement on the present invention, the ferrum in described ferrum charcoal reactor derives from industrial waste ferrum
Bits, waste material iron filings are first used aqueous slkali soaking, to remove dust and the oil stain on scrap iron removing surface, Ran Houyong
Clear water rinses repeatedly, then is soaked with acid solution, to go oxide-film and the rust stain on scrap iron removing surface, finally
Repeatedly cleaned with clear water.
As a further improvement on the present invention, the ferrum charcoal mass ratio in described ferrum charcoal reactor is 1:1,
The particle diameter of wherein iron particle<20 mesh, the particle diameter of charcoal granule<100 mesh.
As a further improvement on the present invention, described ferrum charcoal reactor has two, two described ferrum charcoals
Reactors in series connects.
The invention has the beneficial effects as follows：The method of wastewater treatment of the present invention is combined and is employed Aerated micro-electrolysis
Method and Fenton oxidation method, then the Fe producing after micro-electrolysis reaction2+Being available for follow-up Fenton oxidation method makes
With while the water treatment effect that the inventive method has kept, it is possible to decrease processing cost.
