Description
Technical field
The utility model relates to a kind of reactor, especially a kind of five phase multistage catalytic oxidation reactors.
Background technology
As everyone knows, electropotential directly determines oxidation or the reducing power of material.Hydroxyl radical free radical has high oxidizing electrode current potential (2.80v), is only second to F (3.06v).It is one of the strongest oxygenant, and its electron affinity power is 596.3KJ, easy attack height cloud density point.Which dictates that OH attack has rapidity, and by transfer transport and addition reaction, can without reacting with the pollutent in sewage of selecting.By broken chain scission of link, oxidize the contaminants into as carbonic acid gas, water, moieties is directly mineralized into salt, and can not produce secondary pollution.
And the method for common generation hydroxyl radical free radical (as fenton reagent) requires harsher to reaction conditions, must be that PH is in about 5 (PH is about 3 or lower after adding fenton reagent).For can complete reaction be there is, must regulate by the rear alkali of front acid.Complicated operation, running cost is high, work under bad environment.And because Fe2+ concentration is high in system, the waste water after process or easily may occur returning look phenomenon with color.And other such as ultraviolet or ozone also can produce merely OH, but only in the good clean water treatment process of water quality for sterilization, sterilization, the dirt of high-pollution load, waste water are needed to a large amount of energy to maintain, and running cost is high and unstable, is also in laboratory stage at present.

This device improve sewage biodegradability, can flocculence, by oxygenizement, open loop scission of link, opens the rock steady structure that group occurs for some, at reduction organism (COD
cr) while reach and reduce the object of colourity.By further oxide treatment, the ferrous iron in reaction is converted into ferric iron, has both avoided and returned look phenomenon, make use of again ferric throwing out, reached higher removal efficiency with lower cost.
As preferably, establish inner core in tank body, and described packing layer is limited to outside inner core by silk screen, the filler in packing layer is limited to tank interior by silk screen, and filler can not be flowed away with waste water.This structure makes the residence time in the tank body of waste water longer, and inner core plays the effect of traverse baffle to a certain extent, and what increase waste water and filler and oxygenant mixes duration of contact, therefore greatly can improve the processing efficiency of waste water.
As preferably, described dosing mouth has two, is all arranged in inner core, and two dosing mouths can add hydrogen peroxide and the oxygenant containing ferrous ion respectively, are beneficial to interpolation time and the addition of controlled oxidization agent.Because hydrogen peroxide will add in waste water containing the oxygenant of ferrous ion, therefore need the dosing mouth adding hydrogen peroxide to be located at the top of packing layer, and the dosing mouth adding ferrous oxygenant is positioned at the bottom of filler.
As preferably, dosing mouth is fixed with the chemical feed pipe going deep into tank interior, described chemical feed pipe has multiple hole, this structure makes added oxygenant can mix fully with waste water.
Compared with existing oxidation reactor, the utility model has the following advantages:
1. whole apparatus design is reasonable, compact construction, and the mutual restriction of each function part is little, is easy to engineering design, installs and maintenance.
2. the transmittance of quartzite is high, and energy waste is few, does not produce secondary pollution after process.
3. H after uviolizing
2o
2decomposable asymmetric choice net produces the hydroxyl radical free radical of higher concentration.
4., compared with original four phase staged reactors, more reagent cost can be reduced, and treatment effect is better than four phases.
5. reduce water outlet COD
cr, while SS, also can play the effect of sterilization and disinfection.
