| 摘 要： | 水和废水BOD_6测定中.水样稀释比例的正确选择是实验成功的关键之一.本文在文献提供三个稀释系数的基础上.增补一个系数0.043.共得出4个稀释倍数:0.225CODcr.0.15CODcr.0.075CODcr.0.043CODcr.在实际使用时.根据水样来源选择2个.最多3个稀释倍数.同时掌握好接种的有关技术.就能保证样品BOD_5测定一次成功.理论考察和实际应用结果表明.本文改进后的稀释倍数选择方法适用于各类水样BOD_的测定.

| Abstract: | To dilute the samples of water or polluted water is important in BOD_5 analysis on the foundation documents, the new coefficient 0. 043 is added by this chapter, thereby there are four diluted samples: 0. 225CODcr,0. 15COD, 0. 075CODcr, 0. 043CODcr. To select two samples from these,the BOD_5 analysis canbe completed at one time and beusedfor varieties of water and polluted water. |
