针对饮用水消毒过程中存在的影响因素较多、难以控制的问题,应用灰色关联分析法,以氯对粪肠球菌的消毒为例,研究了消毒过程中几种主要影响因素的相对重要性,并评价了Ct值概念的有效性。结果显示,该方法具有所需试验数据少、结果可靠的特点;最终得到各因素的影响程度排序为:Ct值>消毒接触时间>温度>消毒剂浓度>pH值。在运行过程中,应根据具体情况,以Ct值作为消毒过程的控制参数。
Aiming at the problem that there are many influencing factors in the process of disinfection of drinking water and difficult to control, this paper uses the gray relational analysis method to take the chlorine disinfection of Enterococcus faecalis as an example to study the relative importance of several main influencing factors in the process of disinfection, And evaluated the validity of the concept of Ct values. The results show that this method has the characteristics of less required test data and reliable results. The order of influence of each factor is Ct value> disinfection contact time> temperature> disinfectant concentration> pH value. In operation, should be based on the specific circumstances, Ct value as a control parameter of the disinfection process.
