Abstract：
Water pollution in developing countries continues to be a major health problem due to various anthropological activities that contribute to the spread of many parasitic diseases, including those caused by helminths. The aim of this study is to explore the ability of ozone and peroxone to disinfect drinking water contaminated samples with Toxocara canis eggs. The oxidants used were ozone and ozone-hydrogen peroxide combination. The treatment of Toxocara canis eggs was carried out in a 50 ml reactor with an operating volume of 10 ml. The pH conditions (5, 7 and 10) were varied for each treatment. The treatment effect was calculated by counting eggs and examining the condition of the larvae larval condition (whole, broken and hatched larvae) using an optical microscope. The experiment was carried out by exposing the eggs for 60 and 120 minutes to ozone and peroxone. The best results were obtained for helminths treated with the ozone/hydrogen peroxide combination at pH 10, with an inactivation of 79.2%. The synergistic effect of ozone combined with hydrogen peroxide allows higher helminth egg inactivation rates, demonstrating that advanced oxidation processes are a real alternative to apply in the inactivation of Toxocara canis eggs. The results obtained in this study show that the ozone and peroxone treatment could be a useful disinfection process to destroy or inactivate Toxocara canis eggs in processes commonly applied in water treatment.
摘要：
由于各种人类学活动助长了许多寄生虫病的蔓延,发展中国家的水污染仍然是一个重大的健康问题,包括由蠕虫引起的.这项研究的目的是探索臭氧和过氧化物对弓形虫犬卵污染的饮用水样品进行消毒的能力。使用的氧化剂是臭氧和臭氧-过氧化氢的组合。在操作体积为10ml的50ml反应器中进行弓形虫卵的处理。对于每个处理改变pH条件(5、7和10)。通过计数卵和检查幼虫幼虫状况（整个，破碎和孵化的幼虫）使用光学显微镜。通过将卵暴露于臭氧和过氧化物酮60和120分钟来进行实验。在pH为10的条件下用臭氧/过氧化氢组合处理的蠕虫获得了最好的结果，失活率为79.2％。臭氧与过氧化氢的协同作用使蠕虫卵的灭化率更高，证明高级氧化过程是适用于弓形虫犬卵灭活的真正替代方法。这项研究获得的结果表明，臭氧和过氧化物处理可能是一种有用的消毒方法，可以在水处理中常用的过程中破坏或灭活弓形虫犬卵。
