Ecological environment and human health cause safely extreme influence, and traditional biochemical method is difficult that to handle these difficult degradations organic
Thing.High-level oxidation technology is processing organic wastewater with difficult degradation thereby most one of method of application prospect, and it has been increasingly becoming various countries
The hot subject of water technology research.The core of high-level oxidation technology is to pass through outside energy（Luminous energy, electric energy）And material
（O3、H2O2Deng）Lasting input, by a series of physical process and chemical reaction, produce the hydroxyl free with strong oxidizing property
Base（·OH）, the organic pollution in waste water is oxidized to CO2、H2O and inorganic salts etc..In common oxidants, except F2Outside,
OH has higher standard electrode potential than other common oxidants, and its standard electrode potential is up to 2.8V, so almost can be with
Various organic matters in oxidized waste water, therefore be with a wide range of applications.
Fenton oxidation method passes through ferrous sulfate and peroxidating as a kind of wide variety of method in high-level oxidation technology
Mixing the generation OH, the Fe added in water treatment facilities of hydrogen2+And H2O2Optimal proportion is controlled, because the water quality of waste water is
Moment change, so even if having done lab scale, optimal proportion is determined, but in actual motion, this ratio needs to be adjusted
It is whole.But in view of the quality of sewage plant personnel is not universal high at present, it is high to run the requirement of operation, is extremely difficult to preferably expected effect
Fruit.When the device of factory application Fenton oxidation method design is in practical operation, existing needs continuous adjusting apparatus to control oxygen
The shortcomings that chemical drug agent adds.
The content of the invention
A kind of device is provided the invention aims to overcome the deficiencies in the prior art, the device can reduce sewage plant
The work difficulty of staff, as long as putting into the oxidant and the stable real estate of initiator can of fixed proportion in the apparatus
Raw OH is used for wastewater treatment.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of advanced oxidation device for wastewater treatment, it includes retort, is connected with the retort for that will aoxidize
Agent is injected the oxidant holding vessel of the retort, is connected with the retort for initiator to be injected into the retort
Initiator holding vessel, it is connected for the raw water tank that waste water is injected to the retort with the retort；The advanced oxidation
Device also includes being connected to the first water pump, at least one oxidant counteracting tank and the devil liquor recovery after the retort in turn
Tank, first water pump are used to extract the waste water injection oxidant counteracting tank after oxidation reaction, and waste water is finally described in inflow
Devil liquor recovery tank.
Optimally, it also includes at least one precipitation being connected in series between the retort and first water pump
Tank.
Further, it also includes the pans being connected between the settling tank and first water pump.
Optimally, at least one medicine cleaning of evaporator, the medicine cleaning of evaporator and the oxidation are also associated with the oxidant counteracting tank
The second water pump is connected between agent counteracting tank.
Further, the 3rd water pump, the 3rd water pump and the oxidant are also associated with after the devil liquor recovery tank
Counteracting tank connects.
Further, the oxidant counteracting tank is also connected with cleaning fluid recycling can.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：It is connected to by setting
The oxidant holding vessel and initiator counteracting tank of retort inject the oxidant and initiator of fixed proportion into retort, oxidation
Agent and the initiator contact generation OH with strong oxidizing property, OH are harmful in waste water to remove with the abundant haptoreaction of waste water
Material, waste water just complete the processing of waste water by follow-up oxidant resolution process, and the advanced oxidation device has practical, behaviour
Make the characteristics of easy, as long as operating personnel according to fixed proportion add oxidant and initiator can stably generates
OH, reduce the operation difficulty of sewage plant staff.
