Research and Application of Supersaturated Dissolved Oxygen Technology Combined with Magnetization Technology in the Improvement of Water Quality: Taking the South-to-North Water Diversion Project of China as a Pilot Project

Supersaturated dissolved oxygen and magnetization (SDOXM) technology is a composite that combines supersaturated with water technologies. Compared conventional purification technology, the advantages introduced by such include obvious efficient improvement in purified quality without adding any chemicals, removing sludge changing original function of river. In this study, taking Middle-Route (MR) South-to-North Water Diversion Project China (SNWDPC) as pilot project, effects SDOXM process on microbial activity, phytoplankton community structure, removal efficiency main nutritional indexes canal MR were evaluated. Aiming at static flowing bodies, study was divided into two parts: dynamic experiments (two groups: group artificial aquatic plants another plants). The performance system assessed monitoring organic matter well relative light unit (RLU) ATP, changes structure phytoplankton, biofilm carrier activity. During period, able to increase concentration (DO) maintained state supersaturation for more than three days. effect from obvious. changed Bacillariophyta-Cyanophyta type Bacillariophyta-Cyanobacteria type. Finally, introduction has contributed quality. Therefore, can be used new enhance self-restoration ability river natural ecology.
