城市给水管网细菌生长是管道的表面性质 ,细菌对寡养生境的生态适应与消毒剂的性质、剂量、投加方式等共同作用的结果。改良、处理与更新管道材料 ,选择适当的消毒剂与剂量 ,采用合适的投加方式 ,使用常规处理 +活性炭 +消毒 (AOC <30 0 μg乙酸碳 /L时 )工艺或预处理+常规处理 +活性炭 +消毒 (AOC >30 0 μg乙酸碳 /L时 )工艺 ,可有效控制管网细菌生长
The growth of bacteria in urban water supply network is the result of the interaction between the surface properties of the pipeline, the ecological adaptation of bacteria to the environment of the oligotrophic habitat, the nature of the disinfectant, the dosage and the mode of dosing. Improve, process and renew the pipe material, select the appropriate disinfectant and dosage, use the proper dosage method, use conventional treatment + activated carbon + disinfection (AOC <30 0 μg acetic acid carbon / L) process or pretreatment + conventional treatment + Activated carbon + disinfection (AOC> 30 0 μg acetic acid carbon / L hour) process, which can effectively control bacterial growth in the pipe network
