摘　　要：采用非固定模式运行SBR处理低碳氮比校园生活污水,研究及分析系统对COD、氮、磷的去除情况。实验结果表明:相对于运行周期单一恒定的运行模式,运行1周期闲置3周期的运行模式不利于氮的去除,运行任意2个周期,闲置其余2个周期的运行模式可在满足校园污水达标排放的同时降低反应器运行成本和运行时间,达到节约能源,减少运行维护时间的目的。其他改变周期运行模式对去除氮、磷基本无影响,出水中氨氮、COD、磷酸盐、总氮含量均可达到国家GB18918-2002一级A排放标准。The SBR was used to treat low-carbon-to-nitrogen ratio domestic sewage in non-fixed mode,and the removal of COD,nitrogen and phosphorus from the system was studied and analyzed.The experimental results show that compared with the single constant operation mode of the operation cycle,the working condition 4 is not conducive to the removal of nitrogen.The working condition can meet the discharge of the campus wastewater and reduce the operating cost and running time of the reactor,thereby saving energy and reducing operation and maintenance.The purpose of time.Other changes in the cycle operation mode have no effect on the removal of nitrogen and phosphorus.The ammonia nitrogen,COD,phosphate and total nitrogen content in the effluent can reach the national first-class A emission standard of GB18918-2002.
