Treatment of Spent Tetracycline Liquor by Using an Immobilizded-Microbial-Cell A/O Process
固定化细胞厌氧－好氧工艺处理四环素结晶母液的实验研究

Immobilized-microbial-cell (IMC)technology,a new technique for biological wastewater treatment,was used to treat a spent tetracycline liquor. The experimental results showed that the removals of both COD and tetracycline were 96% at a COD loading of 2.07kg/(m3·d). As compared with a conventional A/O process,there was an increase of COD loading by 16.3% and of gas production by 4.57 times.The IMC technology was found to have some further advantuses,including a more stable operatinn and allowing a higher pollutant loading and less sludge generation.
