摘要
以处理20 m3/d城镇生活污水的深沟型气升推流立体循环倒置A2O整体合建氧化沟中试装置为研究平台,通过对影响该工艺运行的有机物的去除效果、硝化反应与反硝化反应效果及除磷效果等因素进行探索及最佳工况的正交试验设计,实验结果表明该工艺对BOD5、COD、SS、NH4-N、TN、TP的平均去除率分别为94.25%、90.11%、98.31%、93.72%7、6.96%、84.05%。
Integrated Reversed A20 and Oxidation Ditch is one of the deep Oxidation Ditches, which is recycled by the up flow. Its treatment capacity is 20 m3/d. This paper explored the influencing factors, such as removal of organic matter, nitration and denitrification reaction etc. , on the operating system and design orthogonal tests for the optimum condition. As a result, the nitrogen and phosphorus removal of this system were available for the town sewage disposal. 94.25% of BOD5, 90.11% of COD, 98.31% of SS, 93.72% of NH4-N, 76.96% of TN, 84.05% of TPwere removed separately.
