本文报道了1991年江苏洪涝灾害期间饮用水污染现状,探讨了预防控制对策及其效果。结果表明,灾区各类饮用水水源遭受严重的生物性污染,超标率显著高于1986～1990年同期平均水平,部分水源检出多种肠道致病菌。受灾初期,全省制订了对策预案,灾期强化的健康教育、水源保护、水质监测、饮水净化消毒和应急供水措施等一系列预防控制对策,使灾区饮用水细菌学质量显著好于1986～1990年同期平均水平,全省及重灾区水性肠道传染病罹患率分别比80年代最高发病年同期下降50.65％和12.27％;饮水消毒与腹泻病控制经济效益显著,投入与产出之比为1:12.24。
This paper reports the status of drinking water pollution during flood and flood in Jiangsu in 1991 and discusses the prevention and control measures and their effects. The results showed that all kinds of drinking water sources in the disaster area suffered serious biological contamination, the exceeding standard rate was significantly higher than the same period from 1986 to 1990, some of the water sources detected a variety of intestinal pathogens. In the early stages of the disaster, the province formulated a series of preventive and control measures including measures for prevention and cure, enhanced health education during flood season, water source protection, water quality monitoring, water purification and disinfection and emergency water supply measures so that the bacteriological quality of drinking water in disaster areas was significantly better than that of 1986 ~ 1990 The average of the same period of last year, the incidence of waterborne enteric infectious diseases in the whole province and hardest hit were reduced by 50.65% and 12.27% respectively compared with the same period of the highest incidence in the 1980s. The economic benefits of drinking water disinfection and diarrhea control were significant, and the ratio of input to output was 1 : 12.24.
