臭氧技术在泳池水处理中的应用

  由于臭氧的氧化作用极强,能以比氯高出百倍的反应速度分解有机物,可有效防止氯与尿素化合成氯胺,同时又能氧化THM的前驱物,而使THM大大降低。臭氧分解后在水中形成的羟基能够使多价金属离子水解成胶体化合物,通过砂滤器而被过滤掉,不仅使水的感观得到改进,又可去除水中被氧化分解的有机物。

  1、臭氧及其二次产物(如羟基)具有最强的杀菌性及灭活病毒的作用,可有效防止传染性疾病的蔓延。实验证明,同样浓度的臭氧杀灭细菌和病毒的效果是氯的600-3000倍,在臭氧浓度为1mg/L时,粪型大肠杆菌的灭活只需要5秒,用同样浓度的氯则需要15000秒。

  2、属于国际公认的环保型绿色杀菌剂,不会对环境造成任何二次污染。

  3、用氯剂消毒时,从水中蒸发出来的氯代有机化合物以及氯气等有毒气体,聚集在泳池上方不易散去,损害人的呼吸器官,严重影响人们的身体健康,而使用臭氧则完全不会产生此种问题。

  4、臭氧可有效分解水中的腐植质,氧化水中的铁、锰离子,分解水中散射光线的微小有机体,从而大大提高水的清澈度,使水呈现出美丽的蓝色,而氯制剂则无此效果。为使水呈蓝色,使用氯制剂的泳池,往往需加入硫酸铜盐,对人极为有害。

  5、加入氯制剂后,必然会导致水的pH值的改变,使人感到不适,因而需加入碱性或酸性物质予以中和。而臭氧是中性物质,不会产生此种问题。

  6、可大大降低水处理工艺的管理及操作难度,同时具有很高的安全性。而氯制剂在运输、储藏、使用时具有一定的危险性。

  7、臭氧可分解水中的有机物且具有微絮凝作用,因而在正常客流量下,可以不用絮凝剂。

  8、在一定的使用条件下,可不必投加氯消剂、絮凝剂、pH调节剂,可将臭氧作为唯一的处理剂。



Application of ozone technology in swimming pool water treatment

Ozone can decompose organic matter at a rate 100 times faster than chlorine because of its strong oxidation. It can effectively prevent the synthesis of chloramines from chlorine and urea, and at the same time oxidize the precursor of THM, which greatly reduces THM. Hydroxyl formed in water after ozone decomposition can hydrolyze polyvalent metal ions into colloidal compounds, which can be filtered through sand filters. It not only improves the sense of water, but also removes oxidized decomposed organic compounds in water.

1. Ozone and its secondary products (such as hydroxyl group) have the strongest bactericidal and inactivating effect on virus, which can effectively prevent the spread of infectious diseases. Experiments show that the same concentration of ozone kills bacteria and viruses 600-3000 times as much as chlorine. When the concentration of ozone is 1 mg/L, the inactivation of fecal Escherichia coli takes only 5 seconds and 15,000 seconds with the same concentration of chlorine.

2. It belongs to the internationally recognized environmental friendly green bactericide, and will not cause any secondary pollution to the environment.

3. When disinfecting with chlorine agents, chlorinated organic compounds and toxic gases such as chlorine vaporized from water accumulate over swimming pools and are not easy to disperse, which will damage human respiratory organs and seriously affect people's health. However, the use of ozone will not cause such problems at all.

4. Ozone can effectively decompose humus in water, oxidize iron and manganese ions in water, and decompose micro-organisms scattering light in water, thus greatly improving the clarity of water, making water appear beautiful blue, while chlorine preparations have no such effect. In order to make the water blue, copper sulfate is often added to swimming pools using chlorine preparations, which is extremely harmful to human beings.

5. The addition of chlorine preparations will inevitably lead to the change of the pH value of water and make people feel uncomfortable. Therefore, alkaline or acidic substances should be added to neutralize it. Ozone is a neutral substance and will not cause such a problem.

6. It can greatly reduce the difficulty of management and operation of water treatment process, and has high safety. Chlorine preparations are dangerous in transportation, storage and use.

7。 Ozone can decompose organic matter in water and has micro-flocculation effect。 Therefore, under normal passenger flow, flocculant can be avoided。

8. Under certain conditions of use, ozone can be used as the only treatment agent without adding chlorine disinfectant, flocculant and pH regulator.
