人工稳定生态系统构建技术应用于宿迁马陵河道治理项目的效果分析

Analysis on the effect of artificial stable ecosystem construction technology applied to the river regulation project of Maling in Suqian

本文以宿迁马陵河为例,在完成外围截污纳管的基础上,利用人工稳定生态系统构建技术进行工程段治理,经过近6个月的水质跟踪监测,分析出河道内水质变化情况。工程实践经验表明:通过泥水界面重塑、生态导流促生、生物竞争抑藻等构建技术综合应用,对于治理类似马陵河等“清水型河道”整治效果较明显。施工完成后水中污染物削减明显,水体透明度升至1.5m(清澈见底),水质长期稳定在地表Ⅱ类水标准,生物丰富度大幅度提升,为“清水型河道”治理提供了经验及借鉴。

Taking Maling River in Suqian as an example,on the basis of completing the peripheral sewage interception and receiving pipe,the artificial stable ecosystem construction technology is used to carry out the treatment of the engineering section.After nearly 6 months of water quality tracking and monitoring,the water quality changes in the river course were analyzed.Engineering practice shows that the comprehensive application of construction technologies such as mud-water interface remodeling,ecological diversion to promote growth,biological competition to inhibit algae,etc.has obvious effect on the regulation of“clean water river”like Maling River.After the completion of the construction,the reduction of pollutants in the water is obvious,the transparency of the water body rises to 1.5m(clear to the bottom),the water quality is stable at the surface Class II water standard for a long time,and the biological richness is greatly improved,providing experience and reference for the treatment of“clear water river courses”.
