摘要
本文根据沼气科研和生产的特点,经过筛选和改进,建立了一种快速测定化学耗氧量的方法。该方法的消化时间为30分钟;可直接测定含量在1500mg/L以下的样品;并适合批量测定。
According to the characteristics of biogas research and production, through slection and modification, one kind of method for rapidly determining chemical oxygen demand is deviloped. The period for sample digestion is shortened in 30 minutes. This method can be directly used to determine the sample in which COD concentration is lower than 1500mg/L and is suitable for a amount of samples.
