This paper introduces the principles of ultraviolet sterilization lamps, explores rational sterilization and disinfection methods according to environment types in different sites of the hospital and proposes suggestions for the sites to be provided with fixedly mounted ultraviolet sterilization lamps and for control methods of ultraviolet sterilization lamps.

通过对麒麟菜多种杀菌工艺进行探讨,比较不同杀菌条件对麒麟菜风味食品外观、口感、质量的影响。结果表明:过氧化氢溶液对麒麟菜杀菌有显著效果,0.3%浓度过氧化氢杀菌10 min为其最佳杀菌工艺,经处理的产品杀菌效果符合要求,感官品质令人满意;醋酸对麒麟菜即食食品杀菌结果表明,2.5%浓度醋酸杀菌40min,可以达到理想的效果;紫外线杀菌20 min,杀菌效果较明显,相对于产品的感官影响较小。

The bacterici dal technologies of flavor food made from Eucheuma were studied with comparing the effect of the different sterilization conditions on the appearance, flavor and quality of the products. The results showed that soaked with 0.3 % concentration of hydrogen about 10 minutes soaking is the optimal sterilization condition. It meets the requirements of germicidal efficacy after the treatment, and the sensory quality is satisfactory. Eucheuma sterilization with acetic was studied in this paper show that it has an ideal effectiveness when treated by 2.5% concentration of acetic with 10 min. on the other way, ultraviolet sterilization with 10 min is effective for sterilization, and its sensory quality is good.

为降低能耗,探索将非热力杀菌技术应用于微生物液态发酵,研究了臭氧在自来水中的溶解、杀菌效果,制备臭氧水并将其用于枯草芽孢杆菌的培养。结果表明,当臭氧水浓度为22.15mg/L、维持时间18 min,可达到无菌要求,残余臭氧经紫外线照射15 min即可满足该菌生产要求。

In order to reduce energy consumption and explore the application of non-thermal sterilization technology in microbial liquid fermentation, this paper studied ozone''s solubility in water and its sterilling efficacy. The ozone water was prepared and used for cultivation of Bacillus subtilis. Results showed that when the ozone concentration in water was 22. 15 mg/L for 18 min, aseptic requirements could be achieved. When the residual ozone was destroyed by UV in 15 min, the water could meet the production requirements of the bacteria.

压载水系统利用紫外线进行杀菌处理的方法,已经是一套很成熟的技术。本文通过增加导流板来改进原有的UV腔体,并通过数值模拟和生物实验的方法来解决实际应用中出现的问题,如辐射剂量不达标,消耗的功率太大等。

Ballast water system using the method of UV sterilization, is already a very mature technology. By adding baffles, this article is to improve the original UV chamber, and through numerical simulation and the experimental of biological approaches to solve the problems in practical application, such as the radiation dose not reaching the standard and consuming too much power.

2013年7—8月,对海南文昌、琼海、万宁、东方等地区100家对虾育苗场的砂滤井、沉淀池、砂滤池、活性炭过滤装置、紫外线杀菌器和化学药物消毒6种不同处理方法组合水处理系统的水处理效果进行调查,探讨了各部分在水处理中的作用。调查结果表明,不同组合的处理方法对海水处理时,90%以上育苗场的育苗海水以砂滤为主,紫外线消毒的只有5%。传统的水处理方式较以往也有所较少,大部分育苗场正开始致力水处理系统、设备的改造与引进。实验结果显示,对砂滤水再经过活性炭过滤、紫外线消毒、甲醛消毒后,对降低COD与总菌含量的作用明显（P〈0.05）,下降比例和去除率分别在22.80%、99.00%以上,但是水中溶解氧含量有下降的趋势,对pH的影响不明显（P〉0.05）。这次调查能够为对虾育苗实际应用和开发新技术提供参考依据。

In July and August 2013, a survey was conducted in Hainan Wenchang, Qionghai, Wanning, East and other regions’100 shrimp hatcheries to investigate the effect of six water treatment methods, including sand filter wells, sedimentation tanks, sand filters, activated carbon filters, ultraviolet disinfection and sterilization chemicals, and discuss the role of the various parts in water treatment. The findings suggest that among different combinations of methods for seawater treatment, more than 90%of seawater breeding nursery use sand filtration, ultraviolet disinfection only accounts for 5%. The traditional treatment methods are less used than in the past, most hatcheries are reforming the water treatment systems and introducing new equipment. Experimental results show that seawater treated firstly by activated carbon filter and then by sand filtration, ultraviolet disinfection and formaldehyde disinfection can reduce COD and total bacterial content significantly (P 0.05).
