Title
The Change of Organics and Nutrients According to Aerobic Condition in SBR Process
이성기Song Key Lee,송영일Young Il Song,곽필정Pil Jeong Kwak
Abstract
We have developed technology to remove nitrogen and phosphorous simultaneously from wastewater by carrying out aerobic and anaerobic operations in a sequencing batch reactor. The experiments were conducted with controlling aeration ratios in order to find out how the changes of aeration time ratio relating to removal of nitrogen and phosporus in SBR process. T-N removal rate, when it has 24hr retention Lime and aeration rate 0.222, was shown 82.6%, T-P 70.0%. In case of 48hr retention time, it turned out to have 85.0% of T-N removal, T-P 78.0% removal rate. If all the conditions can be met as explained above, the domestic wastewater as inffluent is achieved COD_(Mn) 94.8%, T-N 78.1% and T-P 72.7% removal rate.
