OBJECTIVE: To analyze the water quality and trend of domestic drinking water in Dalian from 2011 to 2013, and analyze and evaluate the rapid test results in Dalian. Methods: According to “Standard Test Method for Domestic Drinking Water” (GB 5750-2006), the rapid test data of domestic drinking water in Dalian from 2011 to 2013 were selected. According to the standard of sanitary drinking water (GB 5749-2006) Evaluation. Results: From 2011 to 2013, 1603 samples of drinking water were quickly detected on the spot, with a total pass rate of 90.70%. The main unqualified indicators were turbidity and residual chlorine. high. Conclusion: Increasing the microbiological test items for quick on-site testing can further improve the reliability of on-site rapid test data. Combining the on-the-spot rapid testing technology of domestic drinking water and laboratory testing technology can improve the efficiency and effectiveness of health supervision.
