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.
