Paper Title:
Investigation of Oxytetracycline (OTC) Removal Effectiveness of Aerobic Units and it’s Measurement Optimization
  Abstract

In order to study the effectiveness of aerobic units in removing oxytetracycline(OTC) and explore the effective method to measure OTC in wastewater, the different level of mixed liquor suspended solid(MLSS) and aeration quantity are test in OTC degradation in aerobic unit, the measuring methods are tested and optimized. The result shows that with the condition of (1)extraction buffer solution of NaCl(1mol/L) : oxalic acid(0.5mol/L) : ethanol = 25/25/50,v/v/v; (2) water(added phosphoric acid, pH=3) and acetonitrile as flow phase (V:V=75:25); (3) wavelength at 343 nm could achieve 0.9995 correlation coefficient between the concentration of OTC in the sample and peak area measured. The degradation/removal rate was influenced by aeration intensity, detention time and the mixed liquor suspended solids(MLSS) in the treatment units, and higher removal rate was obtained under the higher concentration of oxygen, MLSS and OTC condition.
