摘要
本文通过对重油、15号机油、正已烷3种有机物质的加入实验,查明了以上物质在标准重铬酸钾法中的氧化情况,并得出在钢铁企业含油废水中,用重铬酸钾法所测得的COD值不能全部包括废水中油类(机油、重油)的有机物质的结论。
The chemical oxygen demand (COD) of the oil-bearing effluent from a iron and steel complex was detemined using the potassium dichromate method by adding heavy oil. engine oil №15 and hexane in order to clarify the extent of oxidation of these three organic substances. It was concluded that it is impossible to determine all contributions of the oils (engine oil. heavy oil) in the effluent to the COD values by this method.
