Monitoring of micropollutants and resistant bacteria in wastewater and their effective removal by boron doped diamond electrode

Popis výsledku v původním jazyce

The first part of our study is focused on the analysis of wastewaters composition from the effluence of four Slovak and three Czech wastewater treatment plants. The presence of 30 psychoactive substances and their main metabolites, antibiotic resistant coliforms and S. aureus were determined. The highest concentrations were observed in the case of cotinine, methamphetamine, tramadol, venlafaxine, and oxazepam. The amount of coliforms ranged from 0.6 to 2.7 log CFU/cm(3). The majority of them showed ampicillin and gentamicin resistance. The amount of S. aureus ranged from 0.3 to 2.7 log CFU/cm(3) with methicillin, penicillin, and erythromycin resistance. The second part of this study was focused on the treatment of respective wastewaters by anodic oxidation of contaminants by boron doped diamond electrodes, which were tested applying various current intensities (12.50, 18.75, 40.00 mA/cm(2)). Obtained results indicate that this method is able to effectively degrade a wide spectrum of pharmaceuticals and drugs that are insufficiently removed by traditional processes at wastewater treatment plants, such as oxazepam, venlafaxine, 3,4-methylenedioxymethamphetamine, cotinine, 11-nor-9-carboxy-Delta 9-tetrahydrocannabinol, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine, and citalopram with the efficiency more than 50%. Moreover, the only 1 h lasting treatment caused the elimination of the total bacteria count including the resistant types under the detection limit.
