标准摘要
[中文适用范围]： 警告——使用本国际标准的人员应熟悉正常的实验室实践。本标准并不旨在解决与其使用相关的所有安全问题（如果有）。用户有责任建立适当的安全和健康规范，并确保遵守任何国家监管条件。重要提示——根据本国际标准进行的测试必须由经过适当培训的人员进行。安全预防措施——活性污泥和污水中含有潜在的致病生物。因此，在处理它们时应采取适当的预防措施。小心处理有毒测试化合物和性质未知的化合物。本国际标准规定了一种评估有机化合物在给定浓度范围内被需氧微生物“易”和“最终”生物降解性的方法。在这种情况下，本国际标准还对术语“易”和“最终”给出了具体定义。该方法适用于以下有机化合物：a) 在测试条件下所用浓度下可溶解 [溶解有机碳 (DOC) 浓度为 10 mg/l 至 40 mg/l]；b) 在测试条件下不挥发或蒸汽压可忽略不计；c) 在玻璃和活性污泥上吸附性不强；d) 在所选测试浓度下对测试微生物无抑制作用。该方法不适用于废水，因为废水中通常含有大量不溶于水的有机碳，而 DOC 测量中未包括这些碳。 [外文原描述]： ISO 7827:2010 specifies a method for the evaluation of the “ready” and “ultimate” biodegradability of organic compounds at a given range of concentrations by aerobic microorganisms. In this context, ISO 7827:2010 also gives specific definitions for the terms “ready” and “ultimate”. The method applies to organic compounds which are: a) soluble at the concentration used under the conditions of the test [dissolved organic carbon (DOC) concentrations of 10 mg/l to 40 mg/l]; b) non‑volatile or having a negligible vapour pressure under the conditions of the test; c) not significantly adsorbable on glass and activated sludge; d) not inhibitory to the test microorganisms at the concentration chosen for the test. The method is not suitable for waste waters, as they usually contain significant amounts of water‑insoluble organic carbon, which is not included in DOC measurements.
