This paper deals with the possibility of treating the wastewater containing RDX by a novel bioassay techuique. The general characteristics of the wastewater were analyzed,and its anaerobic biodegradability was investigated. The experimental results indicate that the anaerobic biotreatment is suitable to apply to this wastewater. The biodegradability could amount to 89.9%,and the pH value of the wastewater could meet anaerobic reactor′s requirements. For lack of nitrogen and phosphorous source as nutrients,it is necessary to add salts containing these two elements into the water in order to meet the ratio of CODBDNP=300~50051. In addition,sulphates exhibit no negative effects on the wastewater biotreatment,and 94% of RDX in the wastewater could be destroyed and removed.

对含黑索今的混合炸药废水的一般特性进行了分析,并用生物测试技术对其厌氧生物可降解性进行试验研究。结果表明,含黑索今的火炸药废水适宜于厌氧生物降解,其厌氧生化可降解性为89.9%;此废水的pH值符合厌氧反应器对进液的要求,但氮、磷营养缺乏,在厌氧废水处理中按CODBD N P=300~500 5 1的比例补充氮、磷,黑索今去除率可高达94%。
