Abstract：Objective The microbial pollution of drinking water in urban and rural Fengcheng City in 2018 was analyzed to provide basis and corresponding technical guidance for improving drinking water quality.Methods During 2018,drinking water including urban centralized water supply,small-scale centralized water supply and decentralized water supply was regularly collected,accordance to the national standard GB/T 5750.12-2006,the total coliform group in water was determined by multi-tube fermentation method,and the microbial indexes were detected.Results In 2018,a total of 205 water samples were tested,of which 73 were substandard,with a failure rate of 35.61%.The unqualified rate of decentralized water supply in watery period was the highest,which was 81.03%.The factory water of urban centralized water supply all met the national standards,with the lowest unqualified rate,so did small-scale centralized water supply in watery period.The unqualified rate of urban centralized water supply source water was 75.00%.Both of urban centralized water supply tap water supply and the small centralized water supply in dry season had 5.00% unqualified rate.Conclusion In 2018,Fengcheng urban centralized water supply source water microorganism pollution is serious,it is necessary to strengthen the management of water source water to ensure the safety of water source water.The microorganism pollution of distributed drinking water supply is very serious,so it is necessary to change the distributed drinking water supply mode,and suggest that the distributed water supply should be changed into small centralized water supply.It is necessary to strengthen disinfection treatment and water quality monitoring,and establish a step-by-step monitoring and supervision reporting mechanism of"village→village committee→town→city"to ensure the safety of drinking water for urban and rural residents.
