摘要
以白洋淀入淀河流孝义河雄安新区段为例,通过对孝义河入淀口河道底泥进行治理、恢复入淀口河流水生动植物群落、靶向改造盲肠段水动力条件等多手段生态治理,改善河段生态现状,恢复水体的自净能力。项目实施后通过监测设备对河段的水质情况进行了靶向监测,结果表明:项目建设后孝义河末端断面出水水质主要指标均不劣于孝义河上游来水断面水质,河口湿地出水达到Ⅳ类时,孝义河尾端出水COD、氨氮、总磷污染物浓度大幅下降,水质得到显著提升,实现了水体自净,研究成果可为今后入淀河流的治理提供参考。
Taking the Xiong'an New section of the Xiaoyi River as an example,multiple ecological measures were taken to improve the ecological status of the river and restore the self purification ability of the water body by controlling the sediment at the entrance of the Xiaoyi River,restoring aquatic flora and fauna communities in the entrance of the Xiaoyi River,and targeted transformation of the hydrodynamic conditions of the cecum section.After the implementation of the project,targeted monitoring was conducted on the water quality of the river section through monitoring equipment.The results showed that the main indicators of the effluent quality at the end of the Xiaoyi River after project construction were not inferior to the water quality at the upstream of the Xiaoyi River.When the effluent from the estuarine wetland reached Class IV,the concentrations of COD,ammonia nitrogen,and total phosphorus pollutants in the effluent at the end of the Xiaoyi River significantly decreased,and the water quality was significantly improved,achieving self purification of the water body.The research results can provide reference for the management of the riverway to the Baiyangdian in the future。
