广州市黑臭水体治理实践与思路探索—以马涌为例谭晓林
(中交广州水运工程设计研究院有限公司,广东 广州 510220)摘要:为解决严峻的城市黑臭水体问题,达到“水十条”的治理目标,改善人们生活居住环境,广航局以广州市马涌黑臭水体治理为试点工程,采取生物修复技术与物理修复技术相结合的方法进行为期两个月的治理。检测结果显示,治理后马涌水体的氨氮、溶解氧、透明度、总磷和化学需氧量等参数有了明显改善 ,黑臭底泥消减了 27cm,马涌水质由劣Ⅴ类转为Ⅴ类,治理效果显著。本工程为广州市黑臭水体的治理提供了理论依据,对于黑臭水体治理技术的应用具有重要的指导意义。关键词:马涌;黑臭水体;原位生态修复;治污环保船Treatment Practice and Thought of Urban Black-odor water body in Guangzhou, A Case Study of Machong
Abstract:In order to eliminate urban black-odor water body, to achieve the governance objective of "Water ten"
and to improve people's living environment, Guangzhou Dredging Company carried out black-odor water body
treatment taking Machong in Guangzhou as a pilot project,which used bioremediation technology combined with
physical repair techniques The pilot project lasted two months. Test results showed that water quality parameters
such as ammonia nitrogen, dissolved oxygen, transparency, total phosphorus and chemical oxygen demand had
improved significantly, the black-odor sediment deposition decreased 27cm. As a result , water quality of
Machong turned into Ⅴ from inferior Ⅴ and the treatment effect is remarkable. This pilot project provided
theoretical basis for the black-odor water body treatment in Guangzhou and was of great guiding significance to
the application of black-odor water body treatment technology.
