污水在排出之前加温,在某特定恒温下杀灭细菌的消毒处理,杀灭到要求的细菌含量水平,需要多长时间,是环境保护实际工作中需要求知的。原污水细菌含量越高,消毒达到所要求的细菌含量水平需要的时间越长,所要求达到的细菌含量水平越低,需要的时间越长;恒温温度越低,需要的时间越长。这就要求正确地设计,进行必要的科学实验,求知有关诸因素的相互关系,寻得恒温下杀灭细菌的规律,从而做好恒温下污水消毒工作。恒温下消毒实验资料的统计分析结果,对于加温消毒时结合污水水体大小,计算使用燃料数量方面,可 Before the sewage is warmed up, it is necessary to know the actual work of environmental protection in order to kill bacteria at a certain constant temperature and kill it to the required level of bacteria. The higher the raw sewage bacteria content, the longer it takes for the disinfection to reach the required bacterial content level, the lower the required bacterial content level, the longer it takes; the lower the isothermal temperature, the longer it will take. This requires that the correct design, conduct necessary scientific experiments, learn about the relationship between various factors, find the law of killing bacteria at a constant temperature, so as to do a good job of sewage disinfection at a constant temperature. The statistical analysis result of the sterilization experiment data at a constant temperature, for the purpose of heating and disinfection when combined with the size of the sewage water, the calculation of the amount of fuel used can be
