摘要
介绍了人工湿地在西北地区应用案例及存在问题,提出“增面积降负荷、优化植物与填料选择、外加保温措施、曝气增氧、多种类型湿地组合使用”的解决方案。利用西北地区大量存在的农、矿废弃物作为基质填料耦合自养反硝化以解决进水低碳氮比的问题,实现以废治污;充分发挥西北地区清洁能源的优势,通过太阳能、风能进行曝气解决低溶解氧问题,进一步降低污水处理的能耗物耗,是未来人工湿地在西北地区的应用的研究方向。
The application status and existing problems of constructed wetlands in Northwest China were introduced.Enlarging the area to reduce load,optimizing the selection of plants and fillers,adding thermal insulation measures,artificial aeration to increase oxygen and configuring a variety of types of wetlands were proposed.A large number of agricultural and mining wastes were used as matrix fillers in the northwestern region to solve the problem of low C/N in the influent thus pollution control with waste was achieved.Taking the advantage of clean energy in Northwest China,solving the problem of insufficient dissolved oxygen through solar and wind energy aeration,and further reducing the energy and material consumption of sewage treatment,is the research direction for the application of constructed wetlands in the northwest in the future.
