摘要
重金属离子的毒害性大使得解决重金属离子污染问题迫在眉睫。而活性污泥是一种良好的生物吸附剂,能够去除水中的重金属离子。通过对活性污泥吸附重金属离子的影响因素进行综合评述,在p H值、温度、吸附时间、活性污泥浓度、重金属离子浓度、共存离子影响、活性污泥表面离子形式等方面进行分析,重点讨论了吸附影响规律及其内在的吸附作用机理,展望了活性污泥吸附重金属离子的应用前景和研究方向。
For the high toxicity of heavy metal ions, the pollution caused by them has become a serious problem needs to be solved as soon as possible. Activated sludge is a good biological adsorbent, which can be used to remove heavy metal ions in water. The factors affecting heavy metal ions adsorption by activated sludge such as： pH value, temperature, adsorption time, activated sludge concentration, heavy metals concentration, coexisting ions, forms of ions on activated sludge surface, and so on, were reviewed and analyzed in detail. The law and intrinsic mechanism of the adsorption were discussed emphatically, and finally, an outlook of the prospect and research direction of heavy metal ions adsorption by activated sludge was provided.
