【摘要】 为了研究直排式厕所排泄物对车内外污染 ,采用了模拟和现场 2种实验手段 ,证明了排泄物对旅客列车的污染状况 ,结果为 :模拟试验碱性液体随列车运行呈不规则变化 ,污染主要集中在第 5、6窗口 ;现场实验直排式厕所的车厢、2节车厢联接处、走行部的阳性率分别为 61.1%、 77.8%、76.2 %。密闭式厕所的阳性率仅为 1.6% (车厢 )。而作为对照样的机车头无论是直排或密闭式厕所均未出现阳性结果更多还原

【Abstract】 Simulated test and on the spot test were used to study on inside and outside pollution of railway carriges by waste of directly drained lavatory.It was showed that motion of the alkaline liquid with the motion of train was unregular in simulated test.Pollution was mainly at No.5 and No.6 carriges.On the spot test showed that positive rates of railway carrige,carrige joint and walking part of train with directly drained lavatory were 66.1%, 77.8% and 76.2% respectively.Positive rate of train with sealed lavatory was only 1.6%(carrige).The end of train was chosen as control,which didn’t show any positive result on either type of train.更多还原
