对戊二醛作为一种水处理杀菌剂在不同浓度、pH值、各种阳离子存在下对大肠杆菌和混合异氧菌作用时的杀菌性能进行了详细研究 ,并考查了戊二醛的腐蚀性和配伍性。同时 ,对戊二醛的杀菌机理作了更深一步的探讨和研究。实验结果表明 ,戊二醛是一种广谱、高效、低腐蚀、配伍性好的杀菌剂 ,机理研究认为和细菌细胞壁中的肽聚糖反应是杀菌的主要原因 The bactericidal activity of glutaraldehyde as a water treatment fungicide in the presence of different concentrations, pH values ​​and various cations on Escherichia coli and mixed heterologous oxygen bacteria was studied in detail, and the corrosivity of glutaraldehyde And compatibility. At the same time, the bacteriostasis mechanism of glutaraldehyde was further explored and studied. The experimental results show that glutaraldehyde is a broad-spectrum, high efficiency, low corrosion, good compatibility fungicides, the mechanism that the bacterial cell wall peptidoglycan reaction is the main reason for sterilization
