活性炭粒径在水处理中影响的研究进展

Research Progress of Activated Carbons with Different Particle Sizes in Water Treatment

微孔性能是影响活性炭吸附性能的主要因素,而微孔发达程度又与活性炭粒径关系密切。活性炭的粒径不仅影响浊度、氨氮、COD的去除率,还影响统水头损失的增长和系统稳定性。本文就国内外关于不同活性炭粒径对浊度、氨氮、COD、不同分子量的去除率和水头损失增长规律方面的研究进展进行了综述、分析,针对提出的问题对今后的研究问题进行了展望。

Microporous performance is the main factor affecting the adsorption performance, and microporous developed is closely associated with activated carbon particle size. Activated carbon particle size not only affect the removal rate of turbidity, ammonia nitrogen, COD and different molecular weight, also affect the growth of the head loss and system stability. In this paper, activated carbon particle size on the removal rate of turbidity, ammonia nitrogen, COD, different molecular weight and the growth of the head loss were summarized and analyzed both at home and abroad, and some suggestions for the future research on activated carbon were also put forward.
