摘要
采用生态浮床为核心,辅以微曝气复氧、纳污减污栅和人工介质等多项技术,对上海市汇丰河黑臭水体进行治理,工程取得了预期效果,水体透明度由原来的平均小于20 cm增加到平均50 cm以上,主要水质指标NH3-N、TP、CODMn的最大净化率平均分别达到了69.9%、80.7%和63.5%,河道生物多样性显著提高。
The smelly water of Huifeng River in Shanghai was treated adopting ecological floating bed （EFB） as well as multiple technologies such as micro-aeration reoxygenation, trash rack and artificial medium. Expectation effect was obtained including that the water transparency changed from 20 cm or less to 50 cm or more averagely and the maximum purifying rates of NH3-N, TP and CODMn reached 69. 9%, 80. 7% and 63. 5% respectively. Correspondingly, bio-diversity in the river increased significantly.
