Abstract
Provided is a device for removing residual chlorine in water through ultraviolet irradiation. A water inlet and a water outlet are respectively arranged at two ends of the lateral face of a casing, one end of the casing is closed, and the other end of the casing is provided with a connector. A closed end of a quartz tube is installed in the casing, and an open end of the quartz tube and the connector of the casing are sealed through a sealing ring. An ultraviolet lamp tube is installed in the quartz tube, and an electrode end of the ultraviolet lamp tube is fixed with the connector of the casing through a sleeve nut and connected with a lamp seat at the outer end of the sleeve nut. The device for removing the residual chlorine in water through the ultraviolet irradiation has the advantages that time for irradiating water is controlled by changing inside structural design of the device and the water flow rate, so that when the water containing the residual chlorine flows through the inside of the casing, the residual chlorine in the water performs photochemical decomposition under the irradiation of ultraviolet, hypochlorous acid and sodium hypochlorite decompose to generate nascent-state oxygen, concentration of the residual chlorine is greatly reduced, and the purpose for removing the residual chlorine in the water is achieved. By means of the device for removing the residual chlorine in water through the ultraviolet irradiation, potential safety hazards and water poor in oxygen are effectively avoided, and treatment cost is greatly reduced.
Description
Technical field
The utility model relates to the device that a kind of ultraviolet lighting is eliminated chlorine residue in the water, belongs to water-treatment technology field.
Background technology
Chlorine has very strong deactivation to pathogenic microorganism, thereby is widely used in sewage and drinking water treatment field.Chlorine disinfectant is in fact the Yangization – reduction process that chlorine and chlorine compound and microorganism cells organism interact and carry out.The process that chlorine is water-soluble such as reaction formula (1) and (2):
Cl
2 + H
2O → HClO + HCl (1)
HClO → H
+ + ClO
- (2)
Show that according to the investigation of 20000 municipal sewage plants, North America being carried out in 1998 sewage work near 60% uses chlorine disinfectant, 24% adopts chlorine disinfectant and follow-up operating method except chlorine residue, and 15% uses disinfection by ultraviolet light, and 1%-2% ozonization technique is only arranged.As seen, in municipal sewage plant's sterilization method, chlorine disinfectant is used widely.The sterilization method commonly used in Drinking Water in China technique is similarly liquid chlorine disinfection.
Water or sewage can contain certain density chlorine residue in the water body after chlorine disinfectant, directly enter water body, are that chemical combination or free residual chlorine all will have a negative impact to environment and HUMAN HEALTH.In addition, when cholorination is killed the disease caused by infectious water pathogenic microorganism, the organism reaction in chlorine and the water, generation has the by product of mutagenesis carcinogenesis, such as haloform (THMs) etc., the THMs long-term existence is in water body, and will produce long term toxicity to human and hydrobiont affect.Therefore avoid the impact of chlorine residue in the water body for protection of the environment and HUMAN HEALTH, must strictly control the chlorine residue in the water body.Various countries and relevant water treatment field have also all been carried out strict regulation to contents of residual chlorine in the water.Chlorine residue should not surpass 0.01mg/L(pipe network tip water in the middle clear direct drinking water water quality of People's Republic of China's city-building industry standard-direct drinking water water quality standard (CJ94-2005)); The World Health Organization (WHO) is about the regulation of drinking-water quality-Guidelines for Drinking-water Quality, and stipulate among the Third Edition: contents of residual chlorine must not be higher than 5 mg/L in the water.International Maritime Organizaton (IMO) stipulates when ship ballast water treatment system is authenticated: residual chlorine concentration must be lower than 0.2mg/L in the water ballast after ship ballast water treatment system is processed.IMO processes Sewage from Ships and has also carried out relevant regulations, in its MEPC.159 (55) resolution-revised enforcement sewage treatment unit ejecta standard and performance test guide rule, clear: as using chlorine as sterilizing agent, should guarantee that residual chlorine concentration is lower than 0.5mg/L in the ejecta.
Eliminating chlorine residue technique is that the chlorine residue in the water behind the cholorination is removed, and makes in the water body genotoxic potential of chlorine residue and disinfection byproduct (DBP) minimum.Chlorine residue removing method commonly used has chemical agent reduction method and active carbon adsorption.
The chemical agent reduction method is to add excessive reductibility medicament and residual chlorine reaction to reach the effect of removal chlorine residue, and medicament commonly used has: sulfurous gas, S-WAT, sodium bisulfite, Sulfothiorine, Sodium Pyrosulfite etc.Relevant chemical reaction is seen reaction formula (3)-(10):

Remove the principle of chlorine residue about gac, have research to think in the activated carbon the very strong free radical of a kind of activity is arranged, can following reaction (reaction formula 11 and 12) occur with chlorine residue:
HClO + C* → C*O + Cl

Some result of study has then been emphasized the katalysis of activated carbon, thinks that HClO resolves into for nascent oxygen ([O]) under the effect of activated carbon, and then with oxidation of coal, reaction formula is such as (13) and (14):
2[O] + C → CO
