Development of Water Disinfection Systems for Seed Production Facilities

水供应经常提供一种有效的含义，用于感染性欲望的引入和传播。无病原体的水资源是水产养殖成功的必要条件。表面水通常用于水产养殖，来自沿海水或河流，可能含有鱼类病原体。这类开放式水供应品应该使用早期治疗来杀死鱼类病原体。排水前的废水污染对环境有好处。通常，治疗系统使用高效率的沙子过滤器，以便在处理前清除紫外线（UV）光或臭氧。鱼类病原体被分成两组，它们对紫外线和TROS的敏感性。敏感病毒包括感染性红细胞性坏死病毒（IHNV）、Oncorhynchus Masou病毒（OMV）、淋巴球菌病毒（LCDV）和日本流感病毒（HIRRV）和格拉阴性细菌。这些微生物被10^4μW·sec/cm^2（UV剂量）或0.1 mg/L（TROS）治疗1 ... More min. Resistant viruses包括感染性肺结核病毒（IPNV）、marine birnavirus、reovirus and fish nodavirus、Gram-positive bacteria、fungi and parasite which are inactivated with a dose of 106？W·sec/m^2 or 0.5 mg/L（Tros）for 1 min。臭氧化海水含有Tros是有毒的，所以在使用前应该先从木炭中取出。由海水（盐水）的电解产生的高氯丁胺的细菌和病毒效应已经被测试。当细菌暴露到0.1毫克/升高氯丁胺时，超过99.99%的V. anguillarum和A. Salmonicida的细胞在1分钟内被杀死，黄尾动脉病毒（YAV）和病毒感染病毒（HIRRV）在不激活后被治疗，0.58毫克/升高氯丁胺1分钟内被杀死。使用废水，超过99%的可活细菌被减少到0.5毫克/升的总残留氯1分钟。电的细菌效应几乎是相同的，而海awater的紫外线辐射（1.0×10^5μW·sec/cm^2）或臭氧化（TROS 0.5 mg/L，1 min）。这个方法很容易处理大体积的水，所以它适合去除废水。Less（低）

Water supplies often provide an efficient means for the introduction and spread of infectious desease. Pathogen-free water sources are often essential for success in aquaculture. The surface waters commonly used in aquaculture come from coastal waters or rivers and may contain the fish pathogens. Such open water supplies should be used prior treatment to kill the fish pathogens. Disinfection of wastewater before discharging is better for the environment.Usually, the treatment systems make use of high efficiency sand filters to clarify the water before treatment with ultraviolet(UV)light or ozonation. Fish pathogens are divided into 2 groups based on their sensitivity to UV and TROs. Sensitive viruses include infectious hematopoietic necrosis virus(IHNV), Oncorhynchus masou virus(OMV), lymphocystis virus(LCDV)and Japanese flounder rhabdovirus(HIRRV), and Gram-negative bacteria. These microorganisms are inactivated or killed by treatment with 10^4μW・sec/cm^2(UV dose)or 0.1mg/L(TROs)for 1 … More min. Resistant viruses include infectious pancreatic necrosis virus(IPNV), marine birnavirus, reovirus and fish nodavirus, Gram-positive bacteria, fungi and parasite which are inactivated with a dose of 106μ W・sec/m^2 or 0.5mg/L(TROs)for 1min. Ozonated seawater containing TROs is toxic to fixh, thus it should be removed by charcoal before using.Bactericidal and virucidal effects of hypochlorite produced by Electrolysis of seawater(salt water)are examined. More than 99.99% cells of V.anguillarum and A.salmonicida were killed when the bacteria were exposed to 0.1 mg/L hypochlorite for 1 min. Yellowtail ascites virus(YAV)and hirame rhabdovirus(HIRRV)were inactivated>99099% after treatment with 0.58 mg/L hypochlorite for 1 min. Using for wastewater, more than 99% of viable bacteria in waste-seawater was reduced treated with 0.5mg/L of total residual chlorite for 1min. The bactericidal effects of electrolysis were almost same as that of ultraviolet irradiation(1.0×10^5μW・sec/cm^2)or ozonization(TROs 0.5mg/L, 1min)of seawater. This method is easy to treat large volume of water, so it suits to disinfection of wastewater. Less
