Eutrophication Regulation and Control by Combination of Microorganism Agents and Aquatic Plants for Urban Ecological Village Landscape Water

Abstract:

As most of water bodies in urban ecological village landscape are closed or sluggish, in addition to point source and non-point source pollution, they are easy to be eutrophicated. Life and environment nearby will be influenced. In this paper, the combination of microorganism agents and aquatic plants were conducted to treat Xinhe East Canal water body. As a result, after 40 days of running, the removal rates of COD_Cr, NH₃-N, TN and TP were around 58.34%, 92.84%, 89.10% and 86.44%, respectively. And the concentration of Chlorophyll a decreased to less than 3 mg/m³. The main parameters can meet the demands of the standard of fifth type water body according to the Chinese environmental quality standards for surface water.
