Rationale for the Combined Use of Biological Processes and AOPs in Wastewater Treatment Tasks

This paper aims to form a unified concept of the integrated use different wastewater treatment methods resistant biological stage technological systems under influence such toxic factors as antibiotics and surfactants. The processes mechanical treatment, ozonation, UV irradiation, electrolytic anodic oxidation were implemented in an electrotechnological facility. Wastewater quality was determined by concentration nitrogen compounds aqueous solutions according method Lurie. Biodiagnostics investigated activated sludge via surfactant action carried out at polyethylene oxide concentrations 10, 30, 50 mg/dm3. As result experiments on after aquaculture, improvement reduction pollutants only indicator “nitrate concentration” determined: 20% oxidation, 15% photolysis. At almost all studied, not completely recovered, which expressed decrease its quantity inability aggregate flakes sludge. diameter growth retardation standard disk with antibiotic (amoxiclav) accumulative culture 17.3 ± 2 mm 4 mg/dm3 31.3 3 6 In process studying state sludge’s biocenosis toxicants, several regularities revealed. directions using combined approaches water defined. structural model facilities aerobic anaerobic bioprocesses together advanced oxidative technologies substantiated.
