摘要
采用外循环原位微生物扩增技术对上海某公园景观水体进行修复,构建了水生植物、硅藻、水生动物相耦合的生态系统,在此基础上分析了公园景观水体修复前后水质的变化情况。结果表明,水生植物、硅藻、水生动物为主构成的系统可以较好修复公园景观水体,处理后COD、氨氮、总氮和总磷均可达到并优于地表水Ⅳ类水质要求。
The extrinsic cycle in-situ microorganism amplification technique is used to rehabilitate the landscape water body of a park in Shanghai, and to build an ecological system of coupling aquatic plant,diatom and aquatic animal. On this basis, the article analyzes the changes of water qualities before and after the rehabilitation of landscape water body in the park. The result shows that the system mainly composed of aquatic plant, diatom and aquatic animal can better rehabilitate the landscape water body of the park. The treated COD, ammonia nitrogen, total nitrogen and total phosphorus can meet and be better than the water quality requirements of the surface water IV class.
