- Abstract:
- A demonstration project was constructed with submerged plants and biological control as the core, as well as lake-entry plant reduction zone and aeration flow generation as the auxiliary technology for typical urban micro-polluted landscape waters in Zhejiang Provincial Archives Bureau. After one year of design, implementation and operation, the monitoring data show that the effluent CODMn and NH4+-N are better than those of level Ⅰ in Environmental Quality Standards for Surface Water (GB 3838-2002). The removal rates of CODMn and NH4+-N are 88.61% and 95.45% respectively. The TN reaches to the quasi-Ⅰ level and the landscape waters transparency is greater than 1 m. The concentration of TP increased in winter, which needs further monitoring and mechanism analysis.
