染料的生物污泥吸附

Adsorption of Dyes by Sludge

综述了活性污泥、厌氧污泥、干污泥、不同方法失活的污泥等对42种染料的吸附结果,并对生物污泥吸附过程中适用的吸附等温线进行了总结,同时讨论了pH、温度、染料初始浓度、干污泥的粒径、离子强度、生物污泥有无活性等因素对生物污泥吸附的影响,并对今后的研究重点进行了展望。

This paper reviews the biosorption by a variety of sludges including activated sludge, anaerobic sludge, dried sludge, dead sludge, etc. for 42 kinds of dyes. The equilibrium and isotherms are summarized. This paper also discusses the effect of various parameters such as pH, temperature, initial concentration of dye, particle size of dried sludge, ion strength, activity of microorganism on the biosorption for dyes. Several key investigation aspects in future are suggested.
