Abstract:

A mobile water purification platform for in-situ treatment of lake and reservoir eutrophication water is proposed in this paper. This platform is composed of water purification unit (mainly including adsorption unit, fine bubble aerator and micro-current electrolysis unit) and instruction control unit, water quality on-line detection unit and propulsion unit. Excessive nutrient is reduced and harmful algal blooms are controlled by removing nitrogen and phosphorus through adsorption unit and fine bubble aerator and inhibiting algal through micro-current electrolysis unit. The optimal dosage of adsorption material, in-situ adsorption time, aeration intensity, current density, electrolytic time and other technical parameters are obtained by experiments of adsorption, micro-porous aeration and micro current electrolysis using high-performance adsorbents, optimal aeration approach and electrode material. Finally, ways to improve the water purification performance and enhance the operation management of this platform are discussed according to the experimental results and subsequent practical applications. Overall, this platform is a new and effective technology of eutrophication treatment, and will provide solutions for the prevention and control of nutrient reduction and algae blooms.
