Application of Combined Ecological Restoration Technology to River Water Purification and Maintenance
In order to explore the practical application effect of the combined ecological restoration technology on the purification and maintenance of river water quality,the technology of"biological bed+micro-aeration+submerged plant"was applied to the ecological restoration and treatment of a river in Shanghai.The results showed that the water quality of the river was obviously improved,and the removal rates of ammonia nitrogen and total phosphorus reached 54.5％～64％and 48.4％～52.8％,respectively.The water quality could meet the standards of surface water category V,even could meet the category Ⅱ and category Ⅲ in most periods.At the same time,the water ecological structure and function have been well restored,which is reflected in the increase of biodiversity and the stability of water ecosystem.After five consecutive years of water quality tracking and testing,the water quality of the river can basically meet the standards of surface water category V,which proves that the engineering technology is feasible,stable and effective,and worthy of promotion in similar urban river treatment and restoration projects.
