【摘要】 本文对上海苏州河污染底泥中KTN、BOD₆、COD_?r的释放进行了研究。释放后悬浮液中浓度比清液稍高,但相差不悬殊。应用释放与悬浮的规律,推导出悬浮释放速率方程,其计算值与实测值的误差不大于40％。此外,还提出了底泥的污染类型分级,为底泥污染程度的评价提供依据。更多还原

【Abstract】 The release of organics (KTN, BOD₅, COD_cr) from polluted bottom sediments of Suzhou River was studied. A velocity equation for organics release was presented and the calculated results were quite close to observed values. Three grades classification and quality standard for pollution assessment of bottom sediment were proposed, which could be taken as the bases for pollution control program of the sediment.更多还原
