Description
Technical field
The invention belongs to the crossing domain of Application of Nuclear Technology and environment protection, be specifically related to a kind of device of removing the stink substance in the micro polluted source.
Background technology
The eutrophication phenomenon is the environmental pollution that many lakes, reservoir suffer, and causes many-sided harm, and its impact that tap water is produced is the most noticeable.Because many cities and area in China, lake, reservoir are important even unique drinking water sources.Such as eutrophic lakes such as Chaohu, East Lake, Dian Chi, Taihu Lake, all using as local important drinking water source.
The eutrophication subject matter that production brings to tap water is, often makes to occur unhappy smell in the Urban water supply, causes discontented on the water quality sense organ of user.Data shows, the material that produces stink in the eutrophication water has kind more than 10, mainly comprise: native monosodium glutamate (Geosmin), the different down alcohol of 2-methyl (2-MIB), 2-isobutyl-3-methoxypyrazine (IBMP), 2-sec.-propyl-3-methoxypyrazine (IPMJP), 2,4,6-Trichloroanisole (TCA) and Trimethylamine etc.These materials itself there is no harm to health, but its stink threshold value very low (several ng/L), as long as odor causing substance is seldom arranged in the water, just are enough to destroy the normal smell of water.
The stink substance that causes in the eutrophication drinking water source is difficult to adopt conventional water purification treatment technology (coagulation-precipitation-filtration-sterilization) effectively to remove, and relies at present the methods such as chemical oxidation, charcoal absorption or biological treatment.The oxygenant that is used for deodorizing has potassium permanganate (KMnSO
4), hydrogen peroxide (H
2O
2) and ozone (O
3) etc.Adding potassium permanganate may increase the colourity of tap water, and introduces metal ion; The oxidation capacity of hydrogen peroxide is inadequate, and deodorizing effect is general; The oxidation capacity of ozone is very strong, but when removing the odor causing substances such as native monosodium glutamate and 2-MIB, can produce new sweet taste or fruity compound.Gac is to remove water the most effective smelly sorbent material, but regeneration of activated carbon and replacement charge are higher.Although the cost of biological treatment is lower, treatment effect is subject to the remarkably influenced of the conditions such as water temperature, pH value, organism easily.
Summary of the invention
The invention provides a kind of device of removing the stink substance in the micro polluted source, can solve techniques such as relying on chemical oxidation, charcoal absorption, biological treatment and remove the shortcomings such as stink substance has in the water running cost height or treatment effect are low.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

Aforesaid a kind of device of removing the stink substance in the micro polluted source is characterized in that: the flow rate of water flow that described water inflow nozzle ejects is 1.0m/s-5.0m/s.
Aforesaid a kind of device of removing the stink substance in the micro polluted source, it is characterized in that: the thickness of the moisture film that described water inflow nozzle ejects is less than or equal to the penetrative quality of electronics speed.
Aforesaid a kind of device of removing the stink substance in the micro polluted source, it is characterized in that: the bottom of described water storage box is provided with water outlet.
Beneficial effect of the present invention: a kind of device of removing the stink substance in the micro polluted source provided by the invention, can degrade fast and efficiently the stink substance that causes in the tap water, remove the unhappy smell in the tap water, improve the user to the satisfactory degree on the water quality sense organ.In addition, the present invention can form combination process with conventional treatment processes such as other biological pre-treatment or coagulation, precipitation, filtrations.The present invention has the advantages such as technique is simple, energy consumption is low, dosage is even, easy control, is fit to process the multiple eutrophication drinking water treatment that causes stink substance.
Description of drawings
A kind of structural representation of removing the device of the stink substance in the micro polluted source of Fig. 1;
Native monosodium glutamate (Geosmin) concentration in Fig. 2 water source is with the variation of absorption dose;
The different down alcohol of 2-methyl in Fig. 3 water source (2-MIB) concentration is with the variation of absorption dose.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of device of removing the stink substance in the micro polluted source, comprise water storage box 1, the upper end of described water storage box 1 one sides is provided with water inflow nozzle 4, the top of described water storage box 1 is provided with electron beam scanning window 2, be connected with rumbatron 3 on the described electron beam scanning window 2, the bottom of stating water storage box 1 is provided with water outlet 5.
When contaminated water source when water inflow nozzle 4 ejects, rumbatron 3 produces the electron beam that is used for the surface sweeping water source, electron beam enters water storage box 1 water source before through 2 pairs of electron beam scanning windows and shines, can degrade fast and efficiently the stink substance that causes in the tap water, remove the unhappy smell in the tap water, improve the user to the satisfactory degree on the water quality sense organ.
