广州城乡过渡区典型村塘生态修复技术与工程示范

以广州市天河区城中村典型的富营养化小型水体—渔沙坦街道蓝屋村村塘为例,探讨城乡过渡区村塘存在的水环境问题及其相应的生态修复技术与综合治理方案。通过采用底泥清理与化学处理、引水净化、增氧、生物浮床、岸线绿化等综合治理措施,污染水体修复与周边景观改善效果明显。CODCr、NH4-N、BOD5、TP指标均达地表水体水质Ⅲ类标准,净化率分别达57.6%、95.1%、65.1%和77.7%。该工程示范项目取得了较好的水环境治理效果,可为解决城市化地区郊区村塘等地表小型水体污染治理提供参考。...

Taken a typical small eutrophic water body-the Lanwu village pond of tianhe district of Guangzhou city as a case,this article explored the water environmental problem and its corresponding ecological restoration technology on metropolis fringe.Through the use of comprehensive control measures such as clean sediment and chemical processing,water purification,aeration,floating rafts,greening and so on,the effect of water restoration and improvement of the surrounding landscape were obviously.The indicators of CODCr,NH4-N,BOD5,TP reached the surface water quality standard,the removal efficiency of these indicators were 57.6%,95.1%,65.1% and 77.7%,respectively.This demonstration project provided a good reference for local and similar areas to improve water quality and landscape of small wate
