BOD是指在规定的条件下水中有机物在好氧微生物作用下,进行好氧分解过程中所消耗的水中溶解氧的量.在此过程中,除有机物外,还包括硫化物、亚铁等还原性无机物质所消耗的氧量.BOD是个条件实验,它受环境气温、水体微生物、水样本身的性质等几个主要方面的因素所影响.在进行实际水样BOD测定时,为验证配制的接种稀释水是否合适和考查分析人员的技术水平,需同步进行两项BOD实验,一是接种稀释水的溶解氧(DO)消耗实验,另一是葡萄糖-谷氨酸标准
BOD refers to the amount of dissolved oxygen in water consumed by aerobic decomposition of organic matter in water under the conditions specified by the aerobic microorganisms, in this process, in addition to organic matter, including the reduction of sulfide, ferrous and the like The amount of oxygen consumed by sexual inorganic substances.BOD is a conditional experiment, which is affected by several major factors such as the ambient temperature, the water body microorganisms, the nature of the water sample itself, etc. In the actual BOD determination of water samples, Inoculation of dilution water is appropriate and to check the technical level of analysts, the need for simultaneous BOD experiments, one is inoculated with dilution water dissolved oxygen (DO) consumption experiment, the other is glucose - glutamic acid standard
