摘　　要：水体黑臭的指标,是研究其成因,判断其黑臭程度,及科学合理地管理水体的重要内容。该文选择了与水体黑臭生化过程有关的一些参数,进行了现场和模拟试验测定研究,结果证明DO、BOD_5、硫酸还原菌数等,与水体黑臭具有较好的相关性。水体黑臭与不黑臭的临界指标为:CH=21.5,DO=1.8mg/L,N=2000个/ml,BOD_5=14mg/L。The index of water black and offensive odor is important on studying its contributing factors, judging degree of water black and offensive odor and scientific management of water. In this paper study on some parameters which are related to black, offensive odor and their biochemical process were presented. The result showed that DO, BOD5 and number of sulfate reducing bacteria have good interrelation with black and offensive odor in water. Critical indexes that water whether or not black and offensive odor are: CH=21.5, DO=1.8mg/L, N=2000/ml, and BOD5=14mg/L.
