摘要:
Referring to the parameter of wastewater treatment plant, the operational parameters of this experiment were listed as followed: The total amounts of inlet water from the three points decreased from 55% to 30% and at last, to 15%; Sludge concentration was between 2500mg/L∼4000mg/L; sludge was about 8d;Aerobic zone DO=2 ∼ 4mg/L:Sludge return ration R=100%:Water temperature was 26∼28?. Change C/N at every influent point. C/N gradually increases from 3.3 to 5, and when C/N was 5, COD in effluent was 13mg/L, total nitrogen was 7mg/L, total phosphorus was 0.56mg/L. The index met the requirement of national one class B standard. © 2011 IEEE.
