A/O模式好氧颗粒污泥运行时间及脱氮除磷研究
|
摘要
目的确定好氧颗粒污泥在A/O运行模式中厌氧、好氧的最佳运行时间,并研究其对脱氮除磷的性能优化程度.方法在SBR反应器中接种成熟的好氧颗粒污泥,并在好氧颗粒污泥开始好氧运行阶段之前增设一段厌氧运行阶段,保持厌氧状态持续运行180 min、好氧状态持续运行300 min,并测其污染物质量浓度,从而选取各自的运行时间.控制系统处于最佳运行时间并与传统好氧模式进行对比试验,通过检测进出水中污染物的质量浓度来分析优化效果.结果厌氧历时和好氧历时分别为60 min、240 min时处理效果最佳.整个运行周期中氨氮、TN、TP的平均去除率达到98.11%、92.97%、96.01%,比好氧运行模式分别提升了0.9%、3.34%、6.31%.结论改变系统的运行方式可进一步降低出水氨氮、TN、TP的质量浓度,满足《城镇污水处理厂污染物排放标准》(GB18918—2002)中一级A排放标准.
The purpose of this paper was to study the best anaerobic and aerobic running time of aerobic granular sludge in anaerobic/aerobic mode and nitrogen and phosphorus removal performance.In the SBR reactor with mature aerobic granular sludge inoculated,an anaerobic operation stage was added before the aerobic operation stage of the aerobic granular sludge to maintain the anaerobic state of 180 min and the aerobic state of 300 min.And the two state concentration of contaminants were measured to select their respective run time.The system was controlled at the optimal running time and was compared with that of the traditional aerobic mode by detecting the concentration of the inlet and outlet of contaminants.The results showed that the best treatment effect is anaerobic for 60 min and aerobic for 240 min and the average removal rates of NH~+_4-N,TN and TP were 98.11%,92.97% and 96.01%.The removal rates of NH~+_4-N,TN and TP in the whole operation cycle were 0.9%,3.34% and 6.31% higher than the aerobic operation mode.By changing the operation mode of the system,the mass concentration of NH~+_4-N,TN and TP in the effluent was further reduced,and all meet the first-class A emission standard.
