摘要
五日生化需氧量BOD_5是一个重要水质指标,普遍采用“标准方法”进行测定。当被测水样中含有无机或有机还原性物质时,则于测定过程中发生溶解氧对这些物质的化学氧化作用,产生化学氧化耗氧。
A sensitive, accurate and handy method is presented for determination of BOD5. Two flasks of culture solution were prepared. Solution of mercuric chloride or con centrated hydrochloric and was put into one flask, so that the bacteria in it would lose activity. Then two flasks were cultured at same time. Five days after, the dissolvedoxygen was determined using iodometry, by which valne of BOD5 was once measured. This method would avoid interference of consumed oxygen of chemical oxidation.
