Description
Technical field
The utility model relates to a kind of device that is used for drinking water safety disinfection, belongs to environmental technology and water treatment field.
Background technology
The Drinking Water in China contaminated water source is increasingly sharpened and is worsened in recent years, has brought bigger harm to human beings'health.Present most of water factory water-purifying process also rests on the traditional technology of " flocculation-precipitation-filtration-chlorine disinfectant ", mainly turbidity, suspended substance, colourity, pathogeny bacterium are purpose in the water to remove, and can not effectively remove the pathogenic bacteria in the water and organism especially dissolved organic matter.Organic existence, on the one hand in the process of chlorination can and the chlorine reaction, generate disinfection byproduct (DBP) (DBPs), as haloform (THMs), halogen acetic acid (HAAs) etc., these materials all are proved or doubt to carcinogenic, teratogenesis, mutagenic three and cause material; On the other hand for ducted heterotrophic microorganism provides nutraceutical matrix, cause microorganism in pipe network, to breed easily and form microbial film at tube wall, cause the secondary pollution of tap water in pipe network.
Liquid electricimpulse technology generally adopts high-voltage pulse power source to form plasma body, integrate senior oxidation technologies such as high energy electron irradiation, wet oxidation, chemical oxidation, photochemical catalytic oxidation, system need not be aided with additional oxidizer, High Temperature High Pressure or add technique means such as light source is a kind of treatment technology of novel concept.Pulsed plasma discharge in water process has physical influence and chemical effect simultaneously, and physical influence can form UV-light and shockwave, and its intensity is determined that by discharge energy chemical effect is mainly impelled the formation of active substance, as OH, H
2O

3Deng.Therefore, UV-light, shockwave and living radical that pulsed discharge plasma technology can utilize discharge to form form multifactor synergies such as high-energy electron, ultraviolet ray, ozone, the enhancement process effect.But the concentration of bacterium is very low in the tap water, and the active substance of pulse plasma discharge generation and energy utilization ratio are not high.And common liquid electricity reactor amplifies difficulty, is difficult to be applicable to big flux water treatment occasion.
Summary of the invention
The purpose of this utility model provides and a kind ofly can make full use of the active substance that produces in the pulsed plasma discharge process, big flux tap water is carried out the pulsed plasma catalytic means of safe disinfection.
The pulsed plasma reaction unit that is used for drinking water safety disinfection of the present utility model, comprise discharge reactor, vertically arranged zig-zag pin electrode and plate electrode in the discharge reactor, the aeration tube battle array is installed below pin electrode and plate electrode, pin electrode links to each other with negative pole with the positive pole of the pulse power respectively with plate electrode, the discharge reactor housing is provided with water outlet and water-in, covering of reactor is porose, the water outlet of discharge reactor links to each other with the water-in of aqua storage tank through the first flow meter, the water-in of discharge reactor links to each other with the water outlet of aqua storage tank through second under meter, and the aeration tube battle array links to each other with blower fan through the 3rd under meter.
During processing drinking water, open the 3rd under meter and air pump earlier, regulate gas speed and ventilate to the discharge reactor aeration tube.The pending water of packing in the aqua storage tank behind the steady air current is opened first, second under meter and water pump, and the water in the aqua storage tank is injected discharge reactor, needs constantly to replenish the water in the aqua storage tank in this process, causes water pump idle running to avoid being blotted by water pump.After gas flow and discharge are all stablized, stop make up water in the aqua storage tank, opening power begins discharge.Water after the processing flows out from the reactor water outlet, and the water in the aqua storage tank is realized safe disinfection through the discharge reactor circular treatment, and gas goes out from the orifice flow on the reactor cap.The utility model device is to utilize the Athermal plasma of pulse plasma discharge generation to drinking water disinfection.Utilize the physical influence and the chemical effect of pulsed plasma discharge in water process, physical influence can form UV-light and shockwave, and its intensity is determined that by discharge energy chemical effect is mainly impelled the formation of active substance, as OH, H
2O
2, O
3Deng.Physical influence and chemical effect synergy are effectively killed lower concentration bacterium in the tap water.
The utility model apparatus structure is simple, and is easy and simple to handle, and running cost is low, can increase substantially the productive rate and the utilization ratio of active substance, strengthens the tap water sterilization, removes the algae effect.The utility model is applicable to the sterilization of big flux tap water, and treatment capacity can reach a tph.
