水生态系统构建在朱家店河等三条河的应用

The Application of Water Ecosystem Construcion in Three Rivers Such as Zhujiadian

文章介绍了水生态系统构建在朱家店河等三条河水环境治理工程中的应用。通过对现状的调查及污染源分析,因地制宜的提出了水生态系统构建的治理思路。结果表明,三条河水质改善明显,总磷、氨氮、溶解氧等主要指标达到《地表水环境质量标准》(GB 3838-2002)Ⅴ类标准,其中氨氮、总磷接近Ⅳ类标准,透明度达0.8 m及以上,实现了河道水质生态双重目标。

This paper introduces the application of water ecosystem construction in water environment treatment projects of three rivers suca as Zhujiadian. Based on the investigation of the current situation and the analysis of pollution sources, this paper puts forward the governance ideas of water ecosystem construction according to local conditions. The results showed that the water quality of the three rivers improved significantly, and the main indicators such as total phosphorus, ammonia nitrogen and dissolved oxygen reached the class V standard of 《Environmental quality standards for surface water》(GB 3838-2002), among which ammonia nitrogen and total phosphorus were close to class IV standard, and the transparency reached 0.8 meters and above, achieving the double goal of river water quality and ecology.
