纯化水设备预处理系统中控制微生物生长的方法有定期消毒、紫外线（UV）光、氯/氯胺、还原剂、二氧化氯。
The methods for controlling microbial growth in the pre-treatment system of purified water equipment include regular disinfection, ultraviolet (UV) light, chlorine/chloramine, reducing agents, and chlorine dioxide.
1.定期消毒：采用排定的时间表或者根据需要使用定期消毒的方法，它包括：热消毒、化学试剂消毒、介质的再生或更换、冲洗或排放。用加热的方法，美国药典中的指示有机物是在60℃以上被杀死，并且大部分治病有机物会不能增殖。当温度大于80摄氏度时会全部杀死，在该温度下的消毒时间是1-2小时，总的循环时间包括加热和冷却时间可能是4-8小时。具体的温度和时长需要根据特定元件或设备的特性确定，热消毒的方法通常在碳床、过滤器以及分配系统中使用。
1. Regular disinfection: Adopt a scheduled schedule or use regular disinfection methods as needed, including thermal disinfection, chemical reagent disinfection, medium regeneration or replacement, flushing or discharge. By heating, the indicator organic matter in the US Pharmacopoeia is killed above 60 ℃, and most of the therapeutic organic matter cannot proliferate. When the temperature exceeds 80 degrees Celsius, all will be killed, and the disinfection time at this temperature is 1-2 hours. The total cycle time, including heating and cooling time, may be 4-8 hours. The specific temperature and duration need to be determined based on the characteristics of specific components or equipment, and thermal disinfection methods are usually used in carbon beds, filters, and distribution systems.
化学消毒剂包括：过氧化氢、碘、氨基化合物以及有机或无机的高氧化性化合物，消毒时间是0.5-4小时，还有附加的消毒剂添加时间及将其从系统中冲洗干净的时间。总循环时间可能是8小时。具体的药剂浓度、消毒时间需要根据特定元件或设备的特性确定。
Chemical disinfectants include hydrogen peroxide, iodine, amino compounds, and organic or inorganic high oxidizing compounds, with a disinfection time of 0.5-4 hours, as well as additional disinfectant addition time and flushing time from the system. The total cycle time may be 8 hours. The specific drug concentration and disinfection time need to be determined based on the characteristics of specific components or equipment.
为将微生物降低到最低而进行的温度控制可使两次消毒的间隔时间延长，由于15℃的温度将降低微生物的生长，防止滞留和盲管也能将微生物的生长降到最低，在停机期间各个操作单元可采用循环管路。
The temperature control carried out to minimize microorganisms can prolong the interval between two disinfections. As a temperature of 15 ℃ will reduce the growth of microorganisms, preventing retention and blind pipes can also minimize the growth of microorganisms. During shutdown, various operating units can use circular pipelines.
