摘要
目的了解武汉市某酒店饮用水的污染原因。方法2004年1月8日,武汉市某酒店饮用水受到污染,在发现污染的当时和处理过程中分别采集酒店内的二次供水(蓄水池水和水箱水)与市政供水,检测感官性状、一般化学和细菌学指标,按《生活饮用水水质卫生规范》(2001)进行评价。结果该酒店二次供水浑浊度增加,最高达3.82NTU;并检出尿素、氨氮和氯化物,其浓度高于市政供水,游离余氯<0.05mg/L,细菌总数最高达940cfu/ml,总大肠菌群最高>1600MPN/100ml,并检出粪大肠菌群(130MPM/100ml)。结论武汉市该酒店饮用水污染原因是地下蓄水池渗漏所致。
Objective To know the cause for contamination of drinking water in a hotel. Methods Samples were taken from the reservoir 1 h, 14 h, 22 h and 33 h after contamination and the perceptible cbaracter, chemical and bacteriological test were done by using the methods in Analytical Methods for Water and Sanitary Standard for Drinking Water Quality（2001）. Results The turbidity increased at 14 h after contamination and the highest level reached 3.82 NTU. The residual chlorine in tap water from the reservoir was less than 0.05 mg/L, the total count of bacteria was 940 cfu/ml, the total coliform bacteria was more than 1 600 MPN/100 ml and fecal coliforms was 130 MPN/100 ml. Conclusion The contamination of drinking water in the investigated hotel is caused by drinking water reservoir leakage, so more attention must be paid to the contamination of drinking water reservoir.
