包头人工湿地污水净化处理系统设计特点

摘要

Wetland restoration techniques are widely used in southern China,but large-scale applications are rare in our cold northern regions. The design of Baotou Yellow River wetland ecological restoration project described a series of artificial wetlands restoration process,i. e.“riverside by-pass type of enhanced treatment process,contact oxidation system,undercurrent wetland complex systems and surface flow wetland complex sys-tem”to deal with the pollution of water in the northern cold regions. It gave the main structures of the design parameters to the northern cold re-gions,summarized the design features,and pointed out the measures and requirements for winter operation and achieved resources utilization of wa-ter reuse with local water needs,which its water quality can reach the town sewage treatment plant discharge standard level of B.%人工湿地污水处理技术在我国南方地区广为应用，但在北方寒冷地区的大规模应用并不多见。针对包头二道沙河的低污染水，采用人工湿地生态修复串联工艺进行处理，即“河滨旁通式强化处理工艺＋接触氧化工艺＋潜流湿地复合系统＋表面流湿地复合系统”。重点介绍了主要构筑物的设计参数，总结北方寒冷地区人工湿地的主要设计特点，提出了包头黄河湿地冬季运行的措施和要求。同时，结合当地用水需要，以中水回用的方式实现湿地出水资源化利用，设计出水水质能够达到中水回用的水质要求。
