佛山市某镇街内河涌污染现状及控制研究

Study on Inland River Pollution Status and Control of a Town in Foshan

城镇河涌综合整治是珠三角城市发达地区各级政府面临的紧迫任务。选取佛山市某镇街内河涌进行水质分析,研究其化学需氧量(COD)、氨氮、总磷、溶解氧(DO)、五日生化需氧量(BOD5)等水质指标。在剖析河涌污染成因的基础上,重点探讨了控制技术在河涌整治过程中的综合应用,为河涌综合整治和水污染减排节能工作提供科学依据。

Comprehensive improvement of urban rivers is an urgent task for many developed regions in Pearl River Delta. Discussions were based on the inland rivers, one of the town in Foshan, which is characterized by COD、ammonia nitrogen、total phosphorus、DO and BOD5 for water quality. Based on the deep analysis of pollution reasons, which focused on the application and practice of basin system control technique, the comprehensive improvement of water pollution can provide a scientific basis for reduction of polluted rivers.
