摘　　要：文章采用磁混凝沉淀+纯膜MBBR组合异位净化技术、强化耦合生物膜+仿生水草生物膜组合原位生态修复技术、水生态系统重构技术、底泥清淤等河道生态修复技术对台州某平原河网的水环境进行整治。项目试运行2个月,水质稳定达到《地表水环境质量标准》(GB3838-2002)中Ⅲ类及以上目标,省控站点氨氮质量浓度0.5 mg/L、溶解氧5.3 mg/L、总磷0.13 mg/L、可见度75 cm。最终结果表明该项目处理效果良好,治理成本低,且磁混凝+自养硝化生态补水异位处理技术对于中轻度污染水体的处理项目运行期间产泥量少、运维成本较低、日处理量较大,具有一定的推广应用价值。The paper aims to improve the water environment of a plain river network in Taizhou through the use of magnetic coagulation sedimentation and pure membrane MBBR combined heterotopic purification technology,enhanced coupling biofilm and biomimetic aquatic grass biofilm combined in-situ ecological remediation technology,water ecosystem reconstruction technology,sediment dredging,and other river ecological remediation technologies.The project has been in trial operation for 2 months,and the water quality has stably reached the Class III and above targets in the Environmental Quality Standard for Surface Water(GB3838-2002).The ammonia nitrogen concentration at the provincial control station is 0.5 mg/L;dissolved oxygen is 5.3 mg/L;total phosphorus is 0.13 mg/L,and visibility is 75 cm.The project has good treatment effect and low governance cost.The magnetic coagulation and autotrophic nitrification ecological water supplement heterotopic treatment technology for treating moderately and slightly polluted water bodies has low sludge production,low operation and maintenance costs,and large daily treatment capacity during the operation of the project,which has certain promotion and application value.
