Abstract:The integration of spin reflux reactor was adopted to treat restaurant wastewater,and the corresponding start-up process was investigated.During the startup of the intermittent operation mode was adopted for the sludge domesticated.Aeration time is eight hours.Settling time is half hour.Discharge time is one hour.Under the condition of air remain unchanged,the sludge of the system was cultivated by gradually increasing sludge load,and the start-up process was completed in only 20 days.The removal of COD,NH+4-N,TN,TP reached 91.81%,81.57%,54.73% and 83.97%.The main pollute discharge target achieves cities sewage treatment plant pollutant discharge standard( GB18918-2002) the second standard
