宁波市中塘河支流黑臭河道治理与生态修复

Improvement and Ecological Remediation of Malodorous River,Zhongtang River Tributary in Ningbo City

中塘河支流(世纪花园小区段)为宁波市内一条黑臭河道,通过曝气造流、种植水生植物、构建水生微生物种群等措施对该河道进行深度治理。运行结果表明,上述工程措施能够有效去除水体中的有机物、氨氮、总磷等污染物,增加水体溶解氧量和透明度,同时需要环保监管与定期运行管理。应用生态修复技术治理城市黑臭河道,在技术上是切实可行的,具有良好的应用前景和社会、环境效益。

The Zhongtang River tributary （Century Garden section） was a malodorous river in Ningbo City. The river water was treated by making flow by aeration, planting aquatic plants and constructing aquatic microbial population. The operation result showed that the above-mentioned measures could effectively remove the organic compounds, ammonia nitrogen, total phosphorus and so on from the river water and increase dissolved oxygen and transparency of the river water. In addition, the environ- mental regulatory enhancement and the regular operation management were helpful to restore the ecologi- cal environment of the river. The ecological restoration is technically feasible for improvement of the malodorous river and has good social and environmental benefits as well as a broad application prospect.
