Background technology
Fenton reagent method is a kind of effective ways for handling high-concentration hardly-degradable industrial organic waste water, be swift in response because of it,
The features such as mild condition such as reaction temperature and pressure and be widely used.Because the core of Fenton's reaction passes through for hydrogen peroxide
Ferrous ion inspires hydroxyl radical free radical, and the reaction needs substantial amounts of ferrous ion to participate in.Therefore the reaction needs to add largely
Ferrous iron, on the other hand also result in more sludge and produce.
Light helps Fenton process to be a kind of new high-level oxidation technology developed based on Fenton reagent method, and its general principle is except logical
Crossing ferrous ion excites hydrogen peroxide to produce outside hydroxyl radical free radical, can also directly excite hydrogen peroxide to produce hydroxyl free with ultraviolet light
Base directly results in organic matter scission of link.Because ferric ion rapidly can will be reduced into ferrous iron by ultraviolet light, therefore greatly
Add the potential available ferrous amount of reaction system greatly.Therefore light helps Fenton reactor to greatly improve organic wastewater
Degradation rate, and reduce the yield of sludge, reactor volume is substantially reduced, and this causes light to help Fenton reactor as mould
Block, integrated product are possibly realized.
But light helps Fenton process to still need to add more ferrous ion, this causes aftertreatment device larger, processing cost
It is higher, the modularization of the technique and integrated application are limited to a certain extent.Iron cement is reclaimed using the method for sequence batch examination
The equipment that uses of method it is larger, and recoverys must be shut down, organic efficiency and recovery quality are relatively low.At present in processing iron cement
Also without related online recycling device application in field.
The content of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model be to provide one kind can online recycling iron urge
The light of agent helps Fenton wastewater treatment equipment, and iron ion in light Fenton can be achieved and is recycled online, sequence batch examination is overcome
The deficiency of recovery, greatly increases treatment effeciency, saves reagent cost and Treatment of Sludge cost.
To achieve these goals, the technical solution adopted in the utility model is：
It is a kind of can the light of online recycling iron catalyst help Fenton wastewater treatment equipment, including light to help Fenton reactor 1, iron
Ion activation device and iron ion separator, wherein：
The iron ion activator includes setting activator water inlet 7, activator on activator staving 5, activator staving 5

5, the other end connects activator dosing mouth 6；Activator delivery port 9, which connects light, to be helped and is set on the water inlet and connecting line of Fenton reactor 1
It is equipped with intake pump 11；
The iron ion separator includes pipe-line mixer 3, and the import of pipe-line mixer 3 connects light and helps Fenton reactor 1
Delivery port and alkali lye dosing mouth 2 is provided with connecting line, the water inlet of the outlet connection hydrocyclone 4 of pipe-line mixer 3
Mouthful, the top of hydrocyclone 4 is system delivery port 10, and bottom is mud discharging mouth, and mud discharging mouth passes through pipeline and the activator mud
Refluxing opening 8 is connected.
The light helps Fenton reactor 1 to use stainless steel cavity, built-in low-pressure lamp or middle pressure uviol lamp.
The water inlet of the hydrocyclone 4 is in side.
The activator staving 5 is sealed cylindrical, and interior setting dividing plate is mixed.
The hydrocyclone 4 is in the top of activator staving 5.
Compared with prior art, the beneficial effects of the utility model are：
The present apparatus employs the mode of light Fenton reactor combination online recycling iron ion, and treatment effeciency has been significantly greatly increased,
Reduce the size of reactor.Online iron ion recovery system in device eliminates sludge treating system, reduces whole system
The size of system.Therefore the device realizes integrated and modularized design.
The online recycling of iron ion is realized in the present apparatus, iron ion energy repetitive cycling is used, save ferrous sulfate medicament
More than 90% is added, the equipment such as sludge compressor are saved.
