重金属对活性污泥微生物的影响

A Review of Effects of Heavy Metals on Activated Sludge Microoganism

本文综述了重金属对活性污泥微生物的影响。人们对铜、锌、镍、铬等单一或复合存在的重金属研究较多,主要是因为他们的毒性和广泛使用。重金属对微生物的影响随金属的种类和形态而不同。重金属对污泥微生物的毒性可用不同的模型如莫氏方程或Sigmoidal方程来模拟。本文还介绍了重金属对原生动物的影响和抑制的测定方法等内容。

This paper reviewed the effelts of heavy metals on activated sludge microorganisms. Copper, zinc, nickel, cadmium and chromium were mostly studied because of their toxicity and being widely used, regardless of single or combination. The microorganism response to these heavy metals varied with species and concentrations of metals. The effects of heavy metals on sludge microorganisms could be described with different models, such as Sigmoidal and Monod equation. Methods to measure the inhibition and the effects on microorganism community were also reviewed.
