| Title | Removal of Ammonia from Aqueous Solutions Using Immolilized cells | ||
| Keyword | |||
| Abstract | As the increasingly serious water pollution problems, development of efficient wastewater treatment technology is a more pressing need. Traditional biological nitrogen removal processes involve two phases of aerobic nitrification and anaerobic denitrification. Aerobic nitrifying bacteria need large supply of oxygen, as the major source of energy consumption; heterotrophic denitrification bacteria need external organic carbon source, not only increase the cost of treatment, but ruaise some residual COD of the effluent water. Therefore autotrophic nitrogen removal process with biological immobilization technology will make microbes in system strong stability, high density, high resistance to toxicity, resistance to high loads, less sludge production, etc., in the field of wastewater nitrogen removal there is a broad application prospect . In this study, under different operating conditions, it was found that system frozen to -20 ℃ for 24 hours and then thawed at room temperature for 24 hours were the best immobilization conditions. And using the continuous process for treating synthetic domestic wastewater, temperature, pH and DO have some certain effect on the removal of ammonia, which DO is more important than other factors. |
