Abstract

Due to the potential microbiological hazard associated with discharging treated sewage into the receiving body, its disinfection is a key issue to protect ecological safety and human health. Water scarcity and drinking water supply, irrigation, rapid industrialization, use of treated water, protection of water sources, overpopulation and environmental protection force us to look for solutions to ensure safe reuse of wastewater, and this depends primarily on the quality of wastewater disinfection. Many wastewater disinfection methods are commonly used. One of the chemical processes of disinfection sludge is ozonation. Ozonation is widely used in wastewater treatment by oxidation, because ozone is a very strong and effective oxidizing agent. Studies have shown that the effectiveness of ozone in disinfecting water and sewage is up to 50% greater than that of chlorine . An additional advantage of this method is that it also eliminates odors that may be unavailable. The article presents the results of research on the effectiveness of ozonation treatment in the disinfection of treated sewage, based on indicator bacteria such as coliforms, including Escherichia coli, mesophiles, psychrophiles, and spores. The study took into account various effects of time (dose) and temperature. For the purpose of this study, both traditional and modern methods of assessing microbiological quality of wastewater were used. The first one is represented by conventional culture measurements and the second one by using a luminometer (ATP) and flow cytometer (FCM).
臭氧在废水消毒中的应用
由于将处理过的污水排放到受纳水体中会产生潜在的微生物危害,因此污水消毒是保护生态安全和人类健康的关键问题。缺水和饮用水供应、灌溉、快速工业化、使用处理过的水、保护水源、人口过剩和环境保护迫使我们寻找确保废水安全回用的解决方案,而这主要取决于废水消毒的质量。目前常用的废水消毒方法有很多。臭氧消毒是污泥消毒的化学工艺之一。臭氧氧化法被广泛应用于废水氧化处理,因为臭氧是一种非常强且有效的氧化剂。研究表明,臭氧对水和污水的消毒效果比氯高 50%。这种方法的另一个优点是,它还能消除可能存在的异味。文章介绍了臭氧处理对处理后污水的消毒效果的研究成果,研究对象是大肠菌群等指示菌,包括大肠埃希氏菌、嗜中菌、嗜精神菌和孢子。研究考虑了时间(剂量)和温度的各种影响。本研究采用了传统和现代两种方法来评估废水的微生物质量。第一种是传统的培养测量法,第二种是使用发光计(ATP)和流式细胞仪(FCM)。
