Skim serum is an industrial effluent from natrual rubber processing factor-ies. It contains about 1 protein and 0.05-0.3 ammoniacal nitrogen, and about 0.01-0.03 reduced sugar etc organic materials.Therefore, It is of higher COD and BOD. The results of determination of waste-water COD and BOD from different rubber processing factories were reported in this paper, Effect of sampling me-thod on determination value, and conversion of relation between BOD~(30)_3 and BOD~(20)_5 value were discussed.

胶清废水是天然橡胶加工时的一种工业废水。其中含有约1%的蛋白质、0.05-0.3%的氨态氮及约0.01~0.03的还原糖等有机物质,因而具有较高的生化需氧量(BOD)和化学需氧量(COD)。本文主要报导两种不同类型加工厂(标准胶厂、浓缩胶乳厂)废水的BOD和COD的测定结果、讨论了取样方法对测定值的影响及各种温度之BOD与BOD_5~(20)之间的换算。
