水质.用活性污泥抑制碳和铵氧化的氧消耗量试验

[中文适用范围]： 本国际标准规定了评价试验材料对活性污泥微生物耗氧量抑制效果的方法。 该方法旨在代表生物废水处理厂的条件。 它提供了测试材料短暂暴露（通常为 30 分钟至 180 分钟或更长时间）后对活性污泥微生物的抑制或刺激作用的信息。 该方法适用于测试水、废水、纯化学品和化学品混合物。 对于化学品，该方法是指在测试条件下可溶解的化学品。 对于低水溶性、高挥发性的材料以及非生物消耗或产生氧气的材料，需要特别小心。 [外文原描述]： ISO 8192:2007 specifies a method for assessing the inhibitory effect of a test material on the oxygen consumption of activated sludge microorganisms. This method is intended to represent the conditions in biological waste-water treatment plants. It gives information on inhibitory or stimulatory effects after a short exposure (usually 30 min up to 180 min or even more ) of the test material on activated sludge microorganisms. This method is applicable for testing waters, waste waters, pure chemicals and mixtures of chemicals. Concerning the chemicals, the method refers to those which are soluble under the test conditions. Special care is necessary with materials of low water solubility or high volatility, and with materials abiotically consuming or producing oxygen.
