Description

光催化紫外线消毒装置 技术领域 Photocatalytic ultraviolet disinfection device

本发明涉及一种水处理消毒装置， 特别涉及一种光催化紫外线消毒装置。 背景技术 The invention relates to a water treatment and disinfection device, in particular to a photocatalytic ultraviolet disinfection device. Background technique

目前， 紫外线消毒主要是通过紫外线的照射， 破坏及改变微生物的 DNA结 构，是细菌当即或不能繁殖后代，达到杀菌的目的。真正具有杀菌作用的是 UV— C紫外线， 因为 C波段紫外线很易被生物体的 DNA吸收， 尤以 253.7nm左右的 紫外线最佳。 20世纪 60年代， 随着高效率、 长寿命紫外灯管的出现， 以及人们 对氯消毒系统安全性问题的广泛关注， 紫外线在水处理领域的应用得到了非常 迅速发展。 At present, ultraviolet disinfection is mainly through ultraviolet radiation, destroying and changing the DNA structure of microorganisms, and the bacteria are immediately or unable to reproduce the offspring and achieve the purpose of sterilization. The true bactericidal effect is UV-C ultraviolet light, because the C-band ultraviolet light is easily absorbed by the DNA of the organism, especially the ultraviolet light of about 253.7 nm. In the 1960s, with the advent of high-efficiency, long-life UV lamps and the widespread concern about the safety of chlorine disinfection systems, the application of UV in water treatment has grown rapidly.

紫外线消毒的缺点主要是： 能耗大、 紫外灯管清洗不彻底， 无持久杀菌能力， 容易造成管网的二次污染； 浊度及水中悬浮物对紫外杀菌效果有较大影响； 对 于某些抗紫外线的病毒需要较高的灭活剂量； 杀灭的细菌有可能会光修复。 由 于细菌、 病菌和病毒长期暴露在太阳光下面， 长时间的进化过程， 使得这些细 菌、 病菌、 病毒产生对单一紫外线的抵抗力， 这种抵抗力被人们定义为活化酶。 活化酶存在于细菌、 病菌、 病毒的细胞内， 一旦细菌和病菌的 DNA受到损伤， 这种活化酶就会发挥功效， 帮助受损部分迅速恢复成原来的状态。 这样一个反 应过程被成为细菌和病菌的复活反应， 在有光的情况下此种反应能进行的非常 迅速。 光催化作为水或污水处理的新技术， 有以下优点： 一是作为应用最广泛的高 活性光催化剂——二氧化钛具有稳定性好、 无毒、 廉价等优点； 二是在紫外线 的照射下， 二氧化钛具备极强的氧化一还原作用， 将光催化剂表面的各种细菌 及污染物摧毁。 但常规化学方法制备的二氧化钛粉末及薄膜一般晶化程度不高， 比表面积低， 造成性能受到一定的影响。 如何提高光催化反应的光量子产率， 替换页 （细则第 26条) 是光催化大规模应用面临的主要难题之一。The main disadvantages of UV disinfection are: high energy consumption, incomplete cleaning of UV lamps, no permanent sterilization, and easy secondary pollution of the pipe network; turbidity and suspended solids in water have a greater impact on UV sterilization; UV-resistant viruses require higher inactivating doses; killed bacteria may be photo-repaired. Due to the long-term exposure of bacteria, germs and viruses to sunlight, these long-term evolutions have made these bacteria, germs, and viruses resistant to a single ultraviolet light, which is defined as an activating enzyme. The activating enzyme is present in the cells of bacteria, germs, and viruses. Once the DNA of bacteria and bacteria is damaged, the activating enzyme works to help the damaged part quickly return to its original state. Such a reaction process is a revitalizing reaction of bacteria and germs, and this reaction can proceed very rapidly in the presence of light. As a new technology for water or sewage treatment, photocatalysis has the following advantages: First, it is the most widely used high-activity photocatalyst - titanium dioxide has the advantages of good stability, non-toxicity, low cost, etc. Second, under the irradiation of ultraviolet light, titanium dioxide It has a strong oxidation-reduction effect and destroys various bacteria and pollutants on the surface of the photocatalyst. However, the titanium dioxide powders and films prepared by conventional chemical methods generally have a low degree of crystallization and a low specific surface area, which causes a certain influence on the performance. How to increase the photon yield of photocatalytic reactions, replace page (Article 26) It is one of the main problems faced by large-scale photocatalysis applications.

然而将光催化和紫外线消毒结合起来使用的水处理装置的效果却不是那么 理想， 现有水处理装置都存在安装不便、 使用寿命短、 效率低等缺陷， 而且使 用紫外线消毒的紫外线灯管清洗的不彻底影响消毒的效果。 However, the effect of the water treatment device combined with photocatalysis and ultraviolet disinfection is not so satisfactory. The existing water treatment devices have defects such as inconvenient installation, short service life, low efficiency, and the use of ultraviolet disinfection ultraviolet lamp cleaning. Does not completely affect the effect of disinfection.

实施例 3 : 控制溶解温度 405 °C , 量取 6份钛酸四丁酯 （化学纯） 液体倒入 不锈钢容器内， 在恒速剧烈搅拌的情况下， 将 30 份无水乙醇滴加到钛酸四丁酯 中， 同时加入 2 ~ 3份柠檬酸 （分析纯） 、 2.5份乙二醇 （分析纯） 制成混合溶 液； 快速移取 1.5份乙酰丙酮（分析纯）到混合溶液中， 在恒速剧烈搅拌的状态 下， 以 0.5滴 /s的速度緩慢加入去离子水 1.5份， 滴毕后加入 N-乙基全氟辛基磺 酰胺 0.002份、 聚丙烯酸钠 0.002份、 六偏磷酸纳 0.002份， 继续搅拌 30分钟， 待溶液形成白色透明溶胶， 将白色透明溶胶静置陈化 30小时， 于是得到具有很 高的分散性及稳定性的二氧化钛溶胶； 采用浸渍-提膜的方法将光催化旋转杆 放入二氧化钛溶胶中，温度控制在 28°C ,浸渍 12小时后取出，提拉速度为 2 mm / s, 湿膜在 75 °C烘箱中洪 15分钟， 然后放入溶胶中进行第二次浸渍， 5分钟 后取出， 送入烘箱中于 1 15 °C烘 15 分钟， 然后在马福炉中以 3 °C / min的速度 升温至 550°C， 保温 2小时， 于是光催化旋转杆的条形叶片上表面均勾的覆盖了 一层超细二氧化钛涂层。 Example 3: Controlling the dissolution temperature of 405 ° C, measuring 6 parts of tetrabutyl titanate (chemically pure) liquid into a stainless steel container, and dropping 30 parts of absolute ethanol to titanium at a constant stirring speed In the tetrabutyl citrate, add 2 ~ 3 parts of citric acid (analytical grade), 2.5 parts of ethylene glycol (analytical grade) to prepare a mixed solution; quickly transfer 1.5 parts of acetylacetone (analytical grade) to the mixed solution, At a constant speed and vigorous stirring, 1.5 parts of deionized water was slowly added at a rate of 0.5 drops/s. After the dropwise addition, 0.002 parts of N-ethyl perfluorooctyl sulfonamide, 0.002 parts of sodium polyacrylate, and sodium hexametaphosphate were added. 0.002 parts, stirring was continued for 30 minutes, the solution formed a white transparent sol, and the white transparent sol was allowed to stand for 30 hours, thereby obtaining a titanium dioxide sol having high dispersibility and stability; The catalytic rotating rod was placed in a titanium dioxide sol, the temperature was controlled at 28 ° C, and after 12 hours of immersion, the pulling speed was 2 mm / s, the wet film was immersed in an oven at 75 ° C for 15 minutes, and then placed in a sol.

在以上制作方法中， N-乙基全氟辛基磺酰胺、 聚丙烯酸钠、 六偏磷酸纳协 同使用， 起到缩聚和控制 TiO2结晶生长的作用， 使偏钛酸凝胶颗粒均勾地分散 在反应体系中， 而乙二醇、 柠檬酸对晶化过程有重要影响， 与 Ti结合后进一步 阻碍了晶体生长， 使 TiO2粒径降低。 In the above preparation method, N-ethyl perfluorooctyl sulfonamide, sodium polyacrylate, and sodium hexametaphosphate are used in combination to function to polycondense and control the crystal growth of TiO2, so that the metatitanic acid gel particles are uniformly dispersed. In the reaction system, ethylene glycol and citric acid have an important influence on the crystallization process. When combined with Ti, the crystal growth is further hindered and the particle size of TiO2 is lowered.

当晶粒尺寸减小到一定程度后， 光能隙蓝移， 对应于更高的氧化 -还原电位， 因而有更强的氧化 -还原能力； 另外， 晶粒尺寸减小后光生载流子迁移到晶粒表 替换页 （细则第 26条) 面的时间大大缩短， 有效地减少了光生电子和光生空穴的体相复合。 因此， 超 细二氧化钛层 631 中的纳米颗粒能显著地提高其光催化活性。When the grain size is reduced to a certain extent, the optical energy gap is blue-shifted, corresponding to a higher oxidation-reduction potential, and thus has a stronger oxidation-reduction ability; in addition, photo-generated carrier migration after grain size reduction To the die table replacement page (Article 26) The surface time is greatly shortened, and the bulk phase recombination of photogenerated electrons and photogenerated holes is effectively reduced. Therefore, the nanoparticles in the ultrafine titanium dioxide layer 631 can significantly improve their photocatalytic activity.

为了验证本发明二氧化钛光催化模块的效果， 以下对条形叶片 63上超细二 氧化钛涂层性能进行检测。 In order to verify the effect of the titanium dioxide photocatalytic module of the present invention, the performance of the ultrafine titanium dioxide coating on the strip blade 63 was examined below.

1. 采用 FEI-SIRION-200型场发射扫描电镜 (FESEM, 美国）观察超细二氧化 钛涂层的表面形态， 透射电镜可以直观地了解这种纳米颗粒的形貌、 几何形态 和粒度分布等， 从而辅助证明粉体颗粒外观特性。 涂层表面均勾地分布着纳米 级球形 TiO2颗粒， 颗粒直径为 20 ~ 30 nm。 并且涂层上排列有均勾分布的孔洞 结构、 直径大约为十几纳米。 由于涂层表面具有多孔结构， 因此提高了超细二 氧化钛涂层 631的比表面积， 从而大大提高了其光催化效率。 1. Using FEI-SIRION-200 field emission scanning electron microscopy (FESEM, USA) to observe the surface morphology of ultrafine titanium dioxide coating, TEM can intuitively understand the morphology, geometry and particle size distribution of the nanoparticle. Auxiliary proof of the appearance characteristics of the powder particles. The surface of the coating is uniformly distributed with nano-sized spherical TiO2 particles with a diameter of 20 ~ 30 nm. And the coating has a pore structure with a uniform hook distribution, and the diameter is about ten nanometers. Since the surface of the coating has a porous structure, the specific surface area of the ultrafine titanium dioxide coating 631 is increased, thereby greatly improving the photocatalytic efficiency.

2.采用 UV-2000型紫外-可见分光光度计 （美国尤尼柯） 对不锈钢网或不锈 钢球表面超细二氧化钛涂层 631进行分析。 2. Ultra-fine titanium dioxide coating 631 on stainless steel mesh or stainless steel ball surface was analyzed by UV-2000 UV-Vis spectrophotometer (Unicoa, USA).

超细二氧化钛涂层 6931的吸收峰 λ max在 250 ~ 270 nm间。 可见本发明在 紫外光范围内有着很好的吸收率， 表明普通杀菌紫外灯就可以激发本发明条形 叶片 63， 二氧化钛涂层 631受激发后产生的空穴一电子对氧化能力将会更强， 可很好地利用紫外灯的光源。 Ultrafine titanium dioxide coating 6931 has an absorption peak λ max between 250 and 270 nm. It can be seen that the present invention has a good absorption rate in the ultraviolet light range, indicating that the conventional sterilizing ultraviolet lamp can excite the strip blade 63 of the present invention, and the hole-electron oxidizing ability generated after the titanium dioxide coating 631 is excited will be stronger. , can make good use of the source of the UV lamp.

3.胶带拉膜试验：釆用胶带拉膜的方法对超细二氧化钛涂层与不锈钢网或不 锈钢球结合性能进行测试， 其测试结果见表 1。 3. Tape pull film test: The bonding performance of ultrafine titanium dioxide coating with stainless steel mesh or stainless steel ball was tested by using a tape drawing method. The test results are shown in Table 1.

替换页 （细则第 26条) 4.光催化性能试验：Replacement page (Article 26) 4. Photocatalytic performance test:

取一方形测试槽， 将略小于测试槽面积的光催化网平放入其中， 倒入三嗪染料 黄 C-2R染色废水 1000 mL , 以能将光催化网刚刚淹没为宜。 用 420W紫外光照 射 2分钟后取出， 测定废水的吸光度和 COD值， 计算脱色率和 COD去除率， 测定结果表明。 废水的脱色率和 COD去除率分别到达了 32. 7 %和 12. 36 % , 推测随着紫外光照射时间的延长， 其脱色率和 COD去除率会进一步提高。 这是 由于超细二氧化钛涂层 63 1 中的 TiO2颗粒吸收了波长为 200nm〜280nm的光子 后， 价带中的电子会被激发到导带， 形成活性很高的电子 (e-)， 同时价带上形成 带正电的空穴 (h+), 从而形成空穴。 电子对。 而涂层表面的 h+可以吸收水中的 02 , 发生如下反应：Take a square test tank, put a photocatalytic net slightly smaller than the test tank area into it, pour 1000 mL of triazine dye yellow C-2R dyeing wastewater, so that the photocatalytic net can be just submerged. After taking 420 W of ultraviolet light for 2 minutes, the absorbance and COD value of the wastewater were measured, and the decolorization rate and the COD removal rate were calculated. The decolorization rate and COD removal rate of wastewater reached 32.7 % and 12.36 %, respectively. It is speculated that the decolorization rate and COD removal rate will be further improved with the extension of UV irradiation time. This is because the TiO2 particles in the ultrafine titanium dioxide coating 63 1 absorb photons with a wavelength of 200 nm to 280 nm, and the electrons in the valence band are excited to the conduction band to form highly active electrons (e-). A positively charged hole (h+) is formed on the belt to form a cavity. Electronic pair. The h+ on the surface of the coating can absorb 02 in the water, and the following reaction occurs:

O2+2H++2e →H2O2 ；O2+2H++2e → H2O2;

H2O2+e→OH +HO - ；H2O2+e→OH +HO - ;

OH+h+→HO - 反应生成了强氧化性的羟基自由基 (HO · )。 HO ·的氧化性能在水体中最强， 可 以氧化大多数有机污染物和一部分无机污染物， 从而达到降解染色废水的目的。 二、 紫外线灯管模块的设计：OH+h+→HO-reaction produces a strong oxidizing hydroxyl radical (HO · ). HO·'s oxidation performance is the strongest in water, which can oxidize most organic pollutants and some inorganic pollutants, thus achieving the purpose of degrading dyeing wastewater.

Quickly remove 1~2 parts of acetylacetone into the mixed solution, slowly add 1~2 parts of deionized water at a rate of 0.5 drops/s with constant stirring at a constant speed. Add N-ethyl after the drop. Perfluorooctylsulfonamide 0.002 ~ 0. 003 parts, sodium polyacrylate 0.002 parts, sodium hexametaphosphate 0.002 parts, continue to stir 30 minutes Clock, the solution forms a white transparent sol, and the white transparent sol is allowed to stand for 30 hours, thereby obtaining a titanium dioxide sol having high dispersibility and stability;

C. 采用浸渍-提膜的方法将光催化旋转杆放入二氧化钛溶胶中， 温度控制在 27 ~ 30°C, 浸渍 12小时后取出， 提拉速度为 2 mm/ s, 湿膜在 70 ~ 80 °C烘箱 中烘 15分钟， 然后放入溶胶中进行第二次浸渍， 5分钟后取出， 送入烘箱中于 105 °C ~ 120°C烘 15 分钟， 然后在马福炉中以 3°C /min的速度升温至 550 °C , 保温 2 小时， 于是光催化旋转杆的条形叶片上表面均勾的覆盖了一层超细二氧 化钛涂层。 C. Using a dipping-lifting method, the photocatalytic rotating rod is placed in a titanium dioxide sol, the temperature is controlled at 27 ~ 30 ° C, and after immersion for 12 hours, the pulling speed is 2 mm / s, and the wet film is 70 ~ 80. Bake in a °C oven for 15 minutes, then put it into the sol for a second dipping, take it out after 5 minutes, send it to the oven and bake at 105 °C ~ 120 °C for 15 minutes, then 3 °C / min in the Mafu furnace. The speed is raised to 550 °C and kept for 2 hours, so that the upper surface of the strip-shaped blade of the photocatalytic rotating rod is covered with an ultra-fine titanium dioxide coating.
