松花江吉林江段有机物(BOD)环境容量计算

The Calculation on the Environmental Capacity of BOD in jilin Section of Songhua River

河流在生物自净过程中,需要不断消耗溶解氧.使接触大气的河水表面不断更新,氧气又不断地补充到水体中去.我们根据多年来对松花江吉林江段监测结果,计算了不同水期的耗氧系数.复氧系数,及自净速度.从而确定了吉林江段哨口控制断面BOD的环境容量.

Rivers need to consume large amount of dissolved oxygen in the process of their biological self- purification. On the other hand, the surfaces of the rivers contacting with atmosphere were constantly refreshed with oxygons added into the rivers.In accordance with the results of monitoring the jilin section of Songhua River for manyyears, we have calculated the oxygen demanding coefficient, oxygen regaining coefficient and the self - purification rate. The environmental capacity of BOD in the section at Shaokou in Jilin is determined.
