Abstract:
The present paper proposes the treatment technology of mobile water purification system for in-situ treatment in lake and reservoir eutrophication water. This system was composed of water purification unit, mainly including adsorptions unit, microporous aeration unit, micro-current electrolysis unit, instruction control unit, water quality on-line detection unit and power supply unit. The goal of excessive nutrient reduction and harmful algal blooms control could be achieved by nitrogen and phosphorus removal by adsorptions unit and microporous aeration unit, and algal inhibition by micro-current electrolysis unit. The optimal dosage of adsorption material, in-situ adsorption time, aeration intensity, current density, electrolytic time and other technical parameters were achieved by the experiment of adsorption, microporous aeration and micro-current electrolysis using high-performance adsorbents, optimal aeration way and electrode material. Finally, the present study prospects the w
ay to improve the water purification performance and enhance the operation management of mobile water purification system was discussed according to the experimental results and subsequent practical application. Overall, the technology of mobile water purification system is a new and effective technology for eutrophication treatment and will provide solutions for prevention and control of nutrient overloading and algae blooms.
