Paper Title:
Study on the Influence Factors of the Improved A2/O Process Used in Swine Wastewater Treatment
  Abstract

An experiment of treating anaerobic fermented hogpen sewage by improved A2/O reactor was carried out to study the influence factors affect the pollution mater reducing rate during the course of combine domestication. After anaerobic fermented cultivation course of hogpen sewage by A2/O technics, thought the treatment system’s parameters included hydraulics reside time (HRT), deliquescent oxygen (DO), and reflux ration of nitrate solution (r) to study the system’s treatment effect. The experiment results indicated that the improved A2/O process starts with a smooth flow mode, the effluent COD, NH3-N removal were steady at about 90%, TN removal rate of up to 60% of available, TP removal rate of 85%, according to the test results, taking into account the energy consumption problem, the best conditions for the system: DO= 3 mg / L, HRT =24 h, nitration liquid reflux ratio 3.
