Abstract
A process for fast purifying water includes such steps as preparing ozone by using (180-200)-nm ultraviolet lamp to radiate air, pumping the mixture of ozone and air into water, and using (232-238)-nm ultraviolet ray to radiate water for removing bacteria and trace organic substances from water. Its reactor is also disclosed. Its advantage is high effect.
Description
The present invention relates to a kind of method and reactor of quickly cleaning water, specifically be to utilize the uviolizing of air and secondary different wave length to produce ozone continuously, and ozone and UV-light combined action are purified waste water, increase the method and apparatus of oxygen in water.
At present, the device that utilizes ultraviolet-sterilization mainly is the ultraviolet irradiation by single wavelength, can not produce ozone in the process, can't realize the synergy function of ultraviolet and ozone, relatively poor to the treatment effects such as organic pollutant in the water, more can not will effectively increase the treating water dissolved oxygen.Development recently and the UV/O that uses
3The Synergistic biocidal device mainly is to utilize the method for one-level ultraviolet and air pump aerating to produce a part of ozone, and has realized UV/O
3Synergy.But this method and apparatus is because of having only the one-level uv irradiating, can not take into account that best ozone takes place and the making full use of of UV-light, and makes the not high or UV of the productive rate of ozone utilize effect bad as sterilizing function.
The objective of the invention is: by the ultraviolet source irradiation of different wave length, in the continuous ozoniferous while, improve UV-light and with the symphyogenetic purifying water effect of ozone.
Method of the present invention is: purification of water quality process branch two-stage is carried out, the first step produces ozone based on the UV irradiation, air produces ozone under the UV-irradiation of 180nm-200nm wavelength, and will mix in its suction water by water sprayer, the water that contains ozone carries out oxidation disinfection under the UV irradiation handles, and water carries out second stage 232-238nm then, preferred 235nm, the UV-irradiation of wavelength makes UV/O
3Combined action reaches the purpose of purifying waste water and increasing oxygen in water.This method does not need extra making-up air device.
The structure such as the accompanying drawing of reactor of the present invention show.Quartz socket tube 2 is housed in first step reaction unit 1, and ultraviolet lamp tube 3, emptying gas-filled valve 4 and the ozone suction tube 5 of a 180nm-200nm is housed in the quartz socket tube: ultraviolet lamp tube 4 is connected in power supply 7 by lead 6; Be furnished with water-in 8 at first step reaction unit, and make it to be connected with water-jet case 9, water sprayer 10, inlet valve 11 and water inlet pipe 12; A side that is preferably in reactor is installed water discharging valve 13 and 14, to arrange the water in the discharger on request; The top of reaction is provided with water outlet 15, links to each other with outlet regulated valve 16 is installed; By pipeline 17 first step reaction unit is connected to second stage reaction unit 18, is provided with water-in 19 in the bottom of second stage reactor; Quartz socket tube 20 is housed in the reaction unit of the second stage, the ultraviolet lamp tube 21 of a 235nm wavelength is housed in the quartz socket tube, and be connected with power supply 7 by lead 22; Final outflow water mouth and water outlet regulated valve 23,24 are housed on the top of second stage reaction unit.
Reactor assembly operating process of the present invention is as follows:
After opening first step flowing water Valve 16 and second stage flowing water Valve 24, open inlet valve 11 again, pending water enters the first order reaction device through water inlet pipe 11, water sprayer 10 and one-level water-in 8, this is after one-level water outlet and flowing water Valve 16 enter the second order reaction device, after treating that water flows out water outlet 23, power-on 7 is started working ultraviolet lamp 3 and 21.At this moment, under the effect of water sprayer, the ozone that the one-level uv irradiating is produced is by mixing in the extraction pipe 5 suction water and with it, this water that contains ozone and air gas mixture carries out purifying treatment through the secondary uv irradiating, constantly mend air, the treatment capacity of regulating water inlet and flowing water Valve may command water by gas-filled valve 4.
Characteristics of the present invention are as follows:
1, adopt the ultraviolet source irradiation of secondary different wave length, the first step is to produce ozone, and the second stage is to purify waste water;
2, adopting water sprayer to make replenish air and processed water enter reactor carries out simultaneously, does not need extra making-up air device;
3, utilize the combined action of ozone oxidation and purple light irradiation, can remove pollutents such as trace organic matter, bacterium in the water, increased the dissolved oxygen of water simultaneously;
4, the water noresidue ozone after handling etc. does not produce new pollutent, has kept trace element, and is safe and reliable.
