摘要

To guarantee water quality of waterscapes in Metal Park of Zhenhai District of Ningbo City, and keep it above the Grade-IV specified in Quality Standard of National Surface Water Environment (GB3838-2002), maintain low maintenance cost and long-term sustainable development of water, basic principles of ecological engineering and aquatic ecosystem balance theory were applied to instruct water treatment in the park. Micro-nano bubble gas-liquid dispersion and plugflow aeration were used to improve water quality.
