Dingxi area during the rural drinking water safety engineering water quality monitoring analysis

Objective The purpose of strengthening rural drinking water safety engineering evaluation of hygiene and quality of health monitoring, explore the establishment of water-borne diseases,evaluation,prediction system.Methods access to information,on-site view and the investigation,telephone verification to add,etc,fill out a questionnaire formulated by the state unity.Collecting dry season,wet period water samples,testing and general chemical indicators of sensory properties,toxicological indicators,bacteriological indicators and related indicators and disinfection 20.Results The safe drinking water projects in rural areas accounted for 55.56%surface water,groundwater,water engineering for the proportion of 44.45%.Supplying engineering design approach with a larger proportion of ground water,Designed with a smaller proportion of total treatment works,some of the works deal with a larger proportion. Rural drinking water safety project of the city's overall pass rate for the water quality of 50%.Conclusion It is suggested a high degree of emphasis on rural drinking water safety issues:First,to increase awareness of the problem of rural drinking water safety.The second is to effectively raise the masses of peasants drinking water safety awareness,to develop good health habits to prevent the spread of diseases.Third,water quality monitoring is an important means to protect drinking water safety.First,the most rural drinking water project fails to request to undertake alexipharmic handling off-work water,water,water factory residual chlorine index unqualified,existing out-of-specification microbiology indicators.Second,rural drinking water project in water,water treatment process planning design and completion acceptance stage,hygiene,quality evaluation health is not up to standard operation situation of problems began.Third,the supply of rural drinking water project quality health management to be strengthened.Highly suggested rural drinking water safety problems:one is to improve rural drinking water safety awareness of the problem.Two is to enhance the peasants of drinking water safety consciousness,develop good health habits,to prevent the spread of disease.Three is the water quality monitoring is an important means to ensure the safe drinking water.
