Abstract: The performance test standards of drinking water treatment plant between China and American are compared. The Chinese reference standards are GB/T 30307, GB/T 35937, GB/T 17218 and the sanitary code issued by the Ministry of Health, and the American reference standard is NSF/ANSI 42/53/61/600. Both of them belong to national standards. The national standard focuses on the preciseness and reproducibility of the test method. Considering the wide range of pollutants, the implementation index requirements are relatively strict. The American Standard simulates people's water habits in daily life, and the test methods fit the actual use, and the coverage of organic pollutants is very wide. By comparing and expounding the standards of the two countries from the aspects of structural performance, health safety and general performance requirements test. On this basis, the paper puts forward the reference points in the process of standard formulation of drinking water treatment plant in China.
