摘要
采用超滤、臭氧、生物活性炭及砂滤等工艺并进行组合,对源水中可溶性有机物和THM前驱物进行预处理。结果表明,超滤 臭氧 生物活性炭工艺组合对水中THM前驱物、DOC、E260及浊度都有明显的去除效果,尤其臭氧氧化对改善THM前驱物和难生物降解有机物的可生化性有十分显著的作用。生物活性炭与臭氧组合能有效地去除饮用水中的有害、有毒物质,提高饮用水的安全性。
The combination process of ultrafiltration/ozonation/biological activated carbon was used for pretreatment of soluble organic substances and precursor of THM in source water.The results showed that the combination process has obvious effect on removal of THM precursor,E260,and turbidity.Especially,the ozonation can significantly improve the biodegradability of THM precursor and refractory biodegradable organic substances.Biological activated carbon combined with ozonation can effectively remove the hazardous and toxic substances from drinking water,and thus improve its safety.
