粉末活性炭在净水处理中应用现状与前景

粉末活性炭(PAC)处理工艺可快速高效地吸附去除水体中各类天然或合成的有机物、芳香族化合物、微污染物质、卤代烃以及铁、锰、重金属离子等有害物质,在净水领域具有广泛的应用意义.探讨了PAC的实际应用及联用其他技术所取得的成果,并基于其对有机物诸如农药、化工原料、气味性化合物、蓝藻毒素、总有机碳等有害物质的有效处理从而改善出水水质,提高出水生物稳定性,着重综述了PAC在净水处理中的研究进展及应用前景.

The Application Status and Prospect of Powdered Activated Carbon in Water Treatment

The treatment technology of powdered activated carbon (PAC) can quickly and efficiently adsorb and remove all kinds of natural or synthetic organic compounds, aromatic compounds, micro-pollutants, halogenated hydrocarbons as well as iron, manganese, heavy metals and other hazardous substances in water, which has extensive and far-reaching application significance in water purification fields. The practical application and remarkable achievements of PAC combined with other technologies were discussed. And based on their effective reduction in pesticides, chemical materials, odor compounds, cyanobacterial toxins, total organic carbon and other harmful substances in organic matter, the water quality and biological stability were improved. A detailed review of research progress and prospect of PAC in water purification was made emphatically.
