摘要：

Laboratory evaluations were conducted of the rate of ammonia biooxidation to nitrite by an autotrophic culture of nitrifiers. Ammonia oxidation biokinetics were found to follow Michaelis-Menten-type relationships. Alterations in Michaelis-Menten kinetics were quantified with elevated temperatures and selected trace organics typical of steel industry type wastewaters. Based on data obtained, the toxic inhibition to biological nitrification decreased in the order of free cyanide, coal tar acid phenolics (derived from a coke plant), phenol, 2,3,6-trimethylphenol, 2-ethylpyridine, 2,4,6-trimethylphenol, complexed cyanides and thiocyanate.
