The effect of metals (Cu2+, Cr3+, Cr6+) on the work of an activated sludge grown in crude oil refining or synthetic wastes was examined. The activated sludge method was found to be applicable for the purification of wastes carrying up to 0.8 mgCu2+/1,15mgCr3+/1, or 20mgCr6+/1. Higher concentrations of these metals inhibited the work of the activated sludge which was evident in inferior purification and reduced intensity of respiration of the activated sludge microorganisms.
研究了金属（Cu2+、Cr3+、Cr6+）对在原油精炼或合成废物中生长的活性污泥工作的影响。发现活性污泥法适用于净化含0.8毫克Cu2+/升、1.15毫克Cr3+/升或20毫克Cr6+/升的废物。这些金属的较高浓度会抑制活性污泥的工作，这在较差的净化效果和活性污泥微生物呼吸强度降低中表现明显。
