| 摘 要： | 本文通过对松花江哈尔滨江段制糖废水一九九一－一九九五年四个冬季的水质监测，以生物化学需氧量（BOD5）、化学耗氧量（COD）及溶解氧（DO）指标作参数说明三者之间的相关性。结果表明有机污染较重的九一－九三年冬季的水质具体测点的BOD5和COD值略有差异，BOD5大于COD值，而它们变化的趋势是同步的，与DO呈反相关，当BOD5和COD值上升，DO值下降，水质变坏；九三－九五年冬糖厂加强了废水排放的处理，BOD5和COD值下降，DO值上升，水质污染程度降低。

| Abstract: | The article reports the monitoring of sugar-refining waste water in winters from 1991-1995,using BOD. COD and index of Do.as parometers to remark.The results show that,in winter of 1992-1993 while organic pollution was hard. the value of BOD and of COD are different at a same monitoring.spot,but their trend of variations are coircide ,and they are negative interrelative.with DOin water while the Values of BOD5 and COD increasing, D.O reduced, and the water quality turned bad.Since in the winters of 1993 1995,the sugar-refining factory ouhancded treatment of waste water.BOD5, COD has increased DOhas reduced.and water quality has became better |
