Odstraňování nutrientů řasovými biofilmy během dočišťování odpadních vod

Presented PhD theses deals with evaluation of use of algal biofilms for nutrients removal from wastewater. The integral part of research was estimation of the comprehensive benefit of the presented technology, including biomass production and phosphorus recovery. The algal biofilm was able to remove 98 % of phosphorus after 24 hours when the PO4-P concentrations in inflowing water ranged from 3 to10 mg.L-1. Different patterns of phosphorus and nitrogen removal were observed. Daily quantity of removed NO3-N ranged from 2 % to 25 % and was highly depended on solar irradiance. The studied biofilm system has a high efficiency for phosphorus removal and, therefore, has great potential for integration into wastewater treatment processes
