Because the removal efficiency of COD in RBC is well, so in the effluent the NO3-3~-N concentration is high, but COD is low.
这是因为,生物转盘的有机物去除效果很好,出水中硝氮浓度较高而碳源含量很低。
The result of small simulant experiment show that the removal efficiency of oil reach more 99% and the removal efficiency of COD reach more 80%. the removal effect of color and heavy metal is good.
实验结果表明,对油的去除率达到99%,对COD的去除率达到80%以上,对色度、重金属、氨氮等也都有很好的去除效果。
The influence of different COD concentrations and kinds of electrolyte to treatment efficiency was investigated, and satisfied results of 90% COD removal and 95% color removal were achieved.
研究了进水浓度、不同电解质的作用对处理效果的影响,获得了COD去除率大于90%、 色度去除率大于95%的处理效果。
