低温低C/N下改良Bardenpho工艺与多级AO工艺的比较
Comparison of Modified Bardenpho and Multi Level AO Processes under Low C/N Influent at Low Temperature
摘要
Abstract
Under the conditions of low temperature(9~13℃)in winter and low C/N influent,the modified Bardenpho process and multilevel AO process were tested respectively to compare the pollutant removal effects under water load rates of 100%,130%and 150%.The process principle,design points,construction and operation costs were compared and analyzed,and the applicable conditions of the two processes were put forward.The results showed that under the same hydraulic residence time(HRT),multi level AO process had better removal effect on TN,but there was no significant difference in the removal performance of CODCr,ammonia nitrogen and TP.In terms of construction and operation costs,multi level AO could save about 11.43%of the total land occupation and 20%of the operation power consumption,but it needed to be equipped with a precise aeration system to give full play to its energy-saving advantages.关键词
