Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple to operate, effective photochemical catalytic oxidation underground water repair system,
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of photochemical catalytic oxidation underground water repair system, comprise well one, well two, photochemical catalytic oxidation equipment, absorbent charcoal adsorption tank, well two is connected by lift pump with photochemical catalytic oxidation equipment, photochemical catalytic oxidation equipment is connected with absorbent charcoal adsorption tank, absorbent charcoal adsorption tank is connected with well one, and well one is provided with injection water pump; Described photochemical catalysis equipment comprises quartz glass tube, ultraviolet lamp, and ultraviolet lamp is enclosed within quartz glass tube, and described quartz glass tube surface-coated has titanium dioxide.
Compared with prior art, the beneficial effects of the utility model are:
Native system is simple in structure, easy to operate, and adopts chemical oxidization method to administer water to pollute, and organism that can oxidative degradation comprises aromatic hydrocarbon, agricultural chemicals, halohydrocarbon and petroleum hydrocarbon etc.The oxygenant adopting is Fenton reagent, and oxidation effectiveness is good, and the time is short, and expense is low.
Accompanying drawing explanation
Fig. 1 is the front view of utility model.
The contaminated underground water of 1-well one 2-injection water pump 3-absorbent charcoal adsorption tank 4-photochemical catalytic oxidation equipment 5-well two 6-in figure.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, a kind of photochemical catalytic oxidation underground water repair system, comprise well 1, well 25, photochemical catalytic oxidation equipment 4, absorbent charcoal adsorption tank 3, well 25 is connected by lift pump with photochemical catalytic oxidation equipment 4, photochemical catalytic oxidation equipment 4 is connected with absorbent charcoal adsorption tank 3, absorbent charcoal adsorption tank 3 is connected with well 1, and well 1 is provided with injection water pump; Described photochemical catalysis equipment 4 comprises quartz glass tube, ultraviolet lamp, and ultraviolet lamp is enclosed within quartz glass tube, and described quartz glass tube surface-coated has titanium dioxide.
Oxygenant is injected 2 to well 1 by syringe pump, and the contaminated underground water 6 of extracting out from well 25 by lift pump enters photochemical catalytic oxidation equipment 4, then enters absorbent charcoal adsorption tank 3, and last contaminated underground water 6 is got back to again well 1.Oxygenant is injected into after Polluted area, fully mixes with pollutent, and redox reaction occurs; 25, well contains oxygenant and pollutent underground water 6 extracts the photochemical catalytic oxidation equipment 4 that enters, and the oxidation capacity of oxygenant is strengthened; Then enter absorbent charcoal adsorption tank 3, pollutent is further removed; Last contaminated underground water 6 enters well 1, circulates again.In repair process, can continue to add oxygenant according to the concentration of pollutent.
Selecting oxygenant is that Fenton reagent mainly comprises hydrogen peroxide and ferrous ion.Its hydroxyl radical free radical mainly producing by when reaction carrys out oxidative degradation organic pollutant.Photochemical catalysis and ferrous ion synergy can promote hydrogen peroxide to produce fast a large amount of hydroxyl radical free radicals, make pollutent fully oxidized.
Native system is simple in structure, easy to operate, and adopts chemical oxidization method to administer water to pollute, and organism that can oxidative degradation comprises aromatic hydrocarbon, agricultural chemicals, halohydrocarbon and petroleum hydrocarbon etc.The oxygenant adopting is Fenton reagent, and oxidation effectiveness is good, and the time is short, and expense is low.
