饮用水处理装置性能测试标准的比较

Comparison of performance test standards for drinking water treatment units

对中美饮用水处理装置的性能测试标准进行比较,中国参考标准为GB/T 30307、GB/T 35937、GB/T 17218和卫生部颁布的卫生规范,美国参考标准为NSF/ANSI 42/53/61/600。两者均属于国家标准,中国标准注重测试方法的严谨性及重现性,考虑到的污染物种类很全,执行的指标要求比较严苛;美国标准模拟人们日常生活中用水习惯,测试方法贴合实际使用,有机污染物覆盖面广。通过从结构性能、卫生安全、一般使用性能要求测试三个方面对两国标准进行比较和阐述,在这个基础上提出对中国饮用水处理装置标准制定过程中可以借鉴的方向。

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.
