摘要
近年来城市污水处理厂尾水深度脱氮受到了广泛关注。本文系统总结了我国不同区域污水处理厂二级生化出水的水质特征,重点讨论和分析了铁炭微电解技术应用于二级出水脱氮的可能性。作为一种深度处理二级出水的有效手段,铁炭微电解技术可大幅降低受纳水体的氮污染负荷,改善受纳水体的水质。
The nitrogen removing of tailwater from waste water treatment plants(WWTPs) has attract more and more attention in recent years. In this review,the water quality characteristics of tailwater from WWTPs in different regions of China were summarized. The possibility of Iron-carbon microelectrolysis technology on denitrification of tailwater from WWTPs was discussed and analyzed in detail. As a promising method for the deep treatment of tailwater from WWTPs,Iron-carbon microelectrolysis technology can slash the nitrogen load as well as improve the water quality of receiving water.
