The increasing pathogenic bacteria threat in irrigation water has become a worldwide concern, prompting efforts to discover a new cost-effective method for pathogenic bacteria eradication, different than those currently in use. In this study, a novel copper-loaded porous ceramic emitter (CPCE) was developed via molded sintering method to kill bacteria from irrigation water. The material performance and hydraulic properties of CPCE are discussed herein, and the antibacterial effect against Escherichia coli (E. coli) and Staphylococcusaureus (S. aureus) was evaluated. The incremental copper content in CPCE improved flexural strength and pore size, which was conducive to enhancing CPCE discharge. Moreover, antibacterial tests showed that CPCE displayed efficient antimicrobial activity, killing 99.99% and more than 70% of S. aureus and E. coli, respectively. The results reveal that CPCE, with both irrigation and sterilization functions, can provide a low-cost and effective solution for bacterial removal from irrigation water.
灌溉水中不断增加的致病细菌威胁已成为全球关注的焦点，促使人们努力寻找一种新的、具有成本效益的方法来消灭致病细菌，与目前正在使用的方法不同。本研究通过模压烧结法开发了一种新型的载铜多孔陶瓷发射器（CPCE），用于杀灭灌溉水中的细菌。本文讨论了 CPCE 的材料性能和水力性能，并评估了其对大肠杆菌（E. coli）和金黄色葡萄球菌（S. aureus）的抗菌效果。CPCE 中铜含量的增加提高了弯曲强度和孔径，有利于增强 CPCE 的排放。此外，抗菌试验表明，CPCE 表现出高效的抗菌活性，分别杀死了 99.99%和 70%以上的金黄色葡萄球菌和大肠杆菌。结果表明，CPCE 兼具灌溉和杀菌功能，可为去除灌溉水中的细菌提供一种低成本、有效的解决方案。
