生物修复技术在白海面黑臭河涌治理中的应用

利用人工曝气、水体生物修复和河道生态恢复等技术，对广州市白海面黑臭水体进行治理。结果表明，在污水进水流量3000～4000m^3／d的条件下，通过生物治理，消除了水体黑臭现象，从上游到下游，水色由暗黄逐步转为黄、黄绿；在上游不断流入污水情况下，CODcr除去率达55％以上，NH3-N除去率为35％，TP除去率达25％以上。本研究为城市黑臭河道，特别是暂时无法截污的城郊河道的治理和养护提供了一套切实可行的方法。

The Appliation of Bioremediation in Baihaimian River

Aeration and bioremediation of river water were combined and applied to control the pollution of the Baihaimian River in Baiyun District,Guangzhou.The result showed that the black color and odors in the upper reaches of the river could be eliminated with the load of wastewater as high as 3000-4000m3/d.The color of the river water was changed gradually from dark yellow in the upper river into yellow,yellow-green in the lower river,where the removal efficiencies of CODcr,NH3-N and TP were above 55%,35% and 25...
