DETECTION AND ANALYSIS OF PHYSICS CHEMISTRY INDEX,TOXIKOLOGIE INDEX AND POLLUTANT INDEX OF POTABLE WATER IN TONGLIAO RAILWAY SYSTEM

[Objective]To find out the current sanitation situation of potable water in Tongliao Khorchin railway system, to ensure the safety of people's drinking water and to provide scientific foundation for improvement. [Methods] The physics chemistry index, toxikologie index and pollutant index of 123 cases of potable water of Tongliao railway system were investigated. [Results] The un-qualification rates of iron, manganese and coli were 49.56%, 55.28% and 21.14%, respectively.The un-qualification rates of chaotic rate, visible material by bare eye, fluoride, amino-nitrogen, nitrite nitrogen, nitrate nitrogen and oxygen con-sumption were also up to 11.38%, 8.13%, 20.33%, 12.20%, 14.63%, 8.94% and 10.57%, and the total qualification rate was 90.67%. [Conclusion] It is necessary to take measures to improve the sanitation condition of potable water in Tongliao railway system. Moreover, ten measures are proposed to solve problems.
