生活饮用水应急集中处理设备现场处理效果初步研究

STUDY ON THE EFFICACY OF THE EMERGENCY CENTRAL FILTRATE WATER SUPPLY EQUIPMENT IN FIELD STUDY

目的评价饮用水应急集中处理设备对洪涝灾区生活饮用水现场处理效果。方法采用现场试验方法,通过检测水中细菌指标对两种饮用水应急集中处理设备除菌效果进行了评价。结果所用两种饮用水应急集中处理设备均由超滤、反渗透和紫外线消毒等3种因子组成。两种设备应急处理后对饮用水中自然菌平均消除率分别为97.13%和99.66%。处理后的饮用水中检不出大肠菌群。处理后饮用水的浊度、溶解性总固体、总硬度、耗氧量、氟化物、氯化物等指标均明显低于处理前,差异有统计学意义。结论两种饮用水应急处理设备对水中微生物和理化因子均有明显消除作用。

Objective To evaluate the efficacy of the emergency central filtrate water supply equipment（ECFWSE） in sticken area.Methods In field study,the bacterial indices in water was tested to evaluated the efficacy of two ECFWSE.Results Both ECFWSE consist of three factors-ultrafiltration,reverse osmosis and ultraviolet disinfection.After treatment the natural bacterial eliminating rates of the two equipments were 97.13% and 99.66% respectively.In treated drinking water coliform group did not been detected.After treatment,water indices of turbidity,total dissolved solids,total hardness,oxygen consumption,fluoride,and chloride in drinking water were significantly decreased than before,and the difference had statistically significant.Conclusions Microbes and physical-chemicals indice can be eliminated by both kinds of the ECFSWE.
