华南地区淋浴软管中微生物再生风险的调查研究

在建筑物生活饮用水的管道环境中, 淋浴软管里温水长时间停滞为细菌和致病菌提供了生长环境。为了解华南地区淋浴软管中微生物的再生风险及诱发因素, 对华南地区具有淋浴设备的家庭进行问卷调查。具体考察了居民淋浴习惯、软管使用习惯及污染情况、水质情况和淋浴水质影响身体健康的认知情况, 对所得数据进行统计分析 。结果显示, 华南地区人群普遍不具备良好的淋浴和软管使用习惯, 缺乏对不良水质会加速人体老化或引起健康问题的认知。统计分析表明, 水温、水质与软管污染程度呈正相关, 淋浴频率和软管更换频率与软管污染程度呈负相关。因此, 不佳的淋浴习惯、水质和软管使用习惯，及对淋浴水质影响身体健康的认知不足, 都为淋浴软管中微生物的生长创造了条件, 增加了致病风险。

Investigation and Analysis of the Risk Caused by Microbial Regeneration in Shower Hose in South China

In the pipeline environment of the drinking water in the building, the long-term stagnation of warm water in the shower hose provides a growth environment for bacteria and pathogenic bacteria. To understand the risk of the regeneration of microorganisms in the shower hoses, a questionnaire survey was conducted on households with household shower facilities in South China by means of random sampling. A percentage analysis of residents’ shower habits, hose use habits, water quality and awareness of the risk of disease from shower hoses was made.A single-factor analysis of the pollution of shower hoses was carried out using variance analysis and correlation analysis. The results show that people in South China generally do not have good shower habits and hose use habits, and lack awareness of the accelerated aging or health risks of shower water quality to humans. Shower water temperature, water quality, shower habits and hose use habits directly affected the pollution of shower hoses. There was a positive correlation between shower water temperature and water quality and the pollution of shower hoses respectively, while shower frequency and hose replacement frequency had a negative correlation with the pollution of shower hoses. The results indicate that poor shower habits, hose use habits, water quality, and weak awareness of the disease risk of shower hoses create conditions for the regeneration of microorganisms in shower hoses and increase the risk of disease.
