嫩江冰封期BOD降解规律的研究

Study on BOD Degradation's Law of Nenjiang River in the Icebound Season

针对嫩江冰封期ＢＯＤ浓度较高，而导致水体中缺氧和死鱼现象发生的问题，采用实验室测定和数学模拟的方法，对各国控断面ＣＢＯＤ和ＮＢＯＤ降解规律进行了研究，从而为确定 ＢＯＤ的自净规律和环境容量提供了科学依据．

Against lach of oxygen and dead fish phonomenon due to the high BOD of Nenjiang River in the icebound season, CBOD and NBOD degradation's law in every Country's section was studied by means of experimental data and mathematics imitation method,thus providing Scientific basis for ascertaining BOD degradation's law and environmental Capacity.
