In this paper, it is considered to be the main cause for decline of dissolved oxygen that the load of organic matter in aerobic tank increases rapidly by analyzing the typical example for decline of dissolved oxygen in aerobic tank of biochemical system for coking waste water. Verified by experiment, the concentration of dissolved oxygen in aerobic tank could return to normal within 1~2 days by taking such measures as increasing the aeration rate of aerobic tank, adding the water with low COD concentration into aerobic tank and strictly controlling the amount of organic matter entering aerobic tank.

文章通过分析焦化废水生化系统好氧池溶解氧下降的典型实例，认为好氧池有机物负荷迅速增大是导致溶解氧下降的主要因素。可采取加大好氧池的曝气量、向好氧池补充COD浓度低的水、严格控制进入好氧池有机物量等措施。经试验验证，采用措施后，好氧池的溶解氧浓度可在1~2天内恢复正常。
