Influence of Biologically Active Substances on Wastewater Treatment Process

The analysis of processes intensification of biological wastewater treatment in aerobic and anaerobic conditions using a new generation of bio-stimulants was performed. The humic preparation and synthetic Melaphen influence was investigated on the biocenosis sludge. The humic preparation and Melaphen provided different effects on the growth of microorganisms in the sludge. It was shown that effect depends on concentration of bio-stimulants and stage of microorganisms growth. The concentrations 10-1 and 10-3 g /dm3 for humic preparation and Melaphen respectively were intensified microorganisms growth. The results show that using humic preparation 10-3 g /dm3 and Melaphen - 10-6 mg/dm3 the most effective for the treatment of wastewater in aerobic conditions, but using humic preparation 10-1 g/dm3 and Melaphen - 10-6 mg/dm3 in anaerobic conditions.
