温度对AOA-SBR工艺同步脱氮除磷的影响
Effects of temperature on simultaneous nitrogen and phosphorus removal using AOA-SBR process
摘要
Abstract
The simulated sewage wastewater was treated continuously using SBR process in order to improve the removal efficiency of nitrogen and phosphorus. Effects of mass ratio of nitrogen to phosphorus(N/P)and sludge retention time(SRT)on simultaneous nitrogen and phosphorus removal were investigated by using anaerobic/aerobic/anoxic sequencing batch reactor (AOA-SBR) at different temperatures. The results showed that removal efficiencies of NH4+-N,TN and TP were 78%,69%and 56%,respectively,and sludge yield (YS)was 0.339 kgSS/(kgBOD5),and phosphorus content in the sludge was 4.68%under the condition of N/P of 2-3 and SRT of 20d at 10 ℃. The removal efficiencies of a NH4+-N,TN and TP weer 80%,66%and 73%,respectively and sludge yield (YS) was 0.225 kgSS/(kgBOD5), and phosphorus content in the sludge was 7.42%under the condition of N/P of 5-7 and sludge age of 10d at 35 ℃. The removal efficiencies of NH4+-N,TN and TP were 88%,83%and 91%,respectively and sludge yield) (YS)was 0.253 kgSS/(kgBOD5),and phosphorus content in the sludge was 6.35%under the condition of N/P of 5-7 and SRT of 15d at 25 ℃. Sludge yield was reduced with the increasing temperature and SRT,and sludge reduction can be realized by adjusting the temperature and SRT.关键词
