中文摘要:

以实验室模拟废水为进水,在SBR反应器中利用好氧颗粒污泥进行N、P的去除效率研究。研究表明:在运行周期约为4 h,进水COD控制在500~1200 mg/L之间,室温条件下,好氧颗粒污泥对COD、氨氮、硝氮、TP的去除率稳定维持在97%、95%、92%、86%,说明好氧颗粒污泥特有的结构特性和生物特性有利于脱氮除磷。

英文摘要:

The experiment of removal efficiency of N, P using aerobic granular sludge was performed in a Sequencing Batch Reactor (SBR). The results show that, in the operation period of about 4h, the inlet COD being controlled between 500 and 1200mg/L, under the temperature of 37 degree, the removal rate of aerobic granular sludge to COD, ammonia and nitrogen, nitrate and nitrogen, and TP maintains steadily at 97%,95%,92% and 86% respectively, which shows the structural and biological characteristics of aerobic granular sludge are favorable to the removal efficiency of N, P .
