【摘要】 目的在符合污染物国家一级排放标准(GB8978-1996)的前提下,确定医院废水消毒效果的最优条件。方法分析影响二氧化氯对医院废水消毒的因素,通过正交实验得出它们对消毒效果的影响比重,按比重大小顺序确定最优条件。结果二氧化氯消毒效果的影响比重依次为:二氧化氯投药量、消毒时间、pH、消毒温度。消毒效果最优的条件为:二氧化氯投加量10mg/L、消毒时间为30m in、pH为6.9、温度为20℃。结论医院可参考此最优条件,根据各自废水特征进行处理。此时消毒效果好,经济费用低。更多还原

【Abstract】 Objective: In accordance with the 1st grate of National Criteria on Polluting Materials(GB8978-1996),to find out the most favorable conditions to deal with hospital waste water.Methods: On cross-experiment,some factors influencing the disinfection effect of ClO2 are analyzed.Results: It shows the factors that influence most significantly in line are: the amount of ClO2,disinfection time,pH value,disinfection temperature.The most favorable condition on disinfection is: ClO 2 amount be10 mg/L,disinfecting time 30 minutes,pH value 6.9,heating temperature 20℃.Conclusion: The result is consultable in disposing of hospital waste water with particular characters,and will perform well with low cost.更多还原
