摘　　要：明确了列车集便器污水主要污染物浓度的影响因素,分别为列车类型、运行时间、运行时段、冲厕用水量、列车乘务员卫生维护习惯,并根据上述影响因素提出列车集便器污水主要污染物浓度的理论计算方法。通过与实际污水水样化验值对比,证明通过该方法计算所得到的列车集便器污水主要污染物浓度计算值与实际水样化验结果相近,并进一步确定了铁路旅客列车集便器污水COD、氨氮的浓度范围,解决了集便器污水处理工程设计原水水质主要污染物浓度难预测的问题。The influence factors on the main pollutant concentration of the waste water from the excrement collector of passenger trains were ascertained in this paper,which consist of the train type,the running time,the running interval,water consumption for washroom,and the habits of clean-keeping by the trainman.Based on that factors analysis,a new theoretic method was proposed to calculate the main pollutant concentration of the waste water from the excrement collector of passenger trains.According to comparison study,it was verified that the ideal value of pollution concentration calculated by using the new method was very close to the real value by testing the actual waste water sample,and the concentration level scale of COD and ammonia-nitrogen in the waste water from the excrement collector of passenger trains were also ascertained.So a difficult problem how to determine the quality of raw water from the excrement collector of passenger trains in the wastewater treatment plant was easily solved.
