摘　　要：以厌氧序批式生物膜反应器(ASBBR)为研究对象,通过对反应器中TP、COD去除情况以及磷化氢和甲烷产量等的长期监测,确定体系达到稳定的除磷和产气效果,并进一步研究了系统稳定运行后典型周期内TP、COD、磷化氢、甲烷、碱性磷酸酶和脱氢酶的变化规律及相关关系。结果表明,ASBBR启动成功后,TP去除率维持在30%左右,COD去除率稳定在95%以上;启动初期产气水平低下,第30天气态磷化氢产量仅为175.00 pg,之后产气能力逐步提高,启动成功后,平均总产气量达到2022.50 mL/d,平均产甲烷量为1095.29 mL/d,气态磷化氢产量达到2212.65 pg/d;根据典型周期内的监测数据,结合态磷化氢产量和碱性磷酸酶呈显著正相关性(R^2=0.908,P<0.01),甲烷产量与脱氢酶呈显著正相关性(R^2=0.847,P<0.01)。Taking an anaerobic sequencing batch biofilm reactor(ASBBR)as the research object,stable phosphorus removal and gas production were achieved in ASBBR through long-term monitoring of the TP and COD removal effect,phosphine production and methane production.The changes and correlations of TP,COD,phosphine,methane,alkaline phosphatase and dehydrogenase in a typical cycle of the system were further studied after stable operation.The removal rates of TP and COD maintained 30% and above 95% respectively after start-up of the ASBBR.The gas production was low during the initial stage of start-up,and the gaseous phosphine production was only 175.00 pg on the 30th day.Then,the gas production capacity gradually increased,and the production of total gas,methane and gaseous phosphine reached 2022.50 mL/d,1095.29 mL/d and 2212.65 pg/d after successful startup.According to the data monitored in a typical cycle,the matrix-bound phosphine production was significantly positively correlated with alkaline phosphatase(R^2=0.908,P<0.01),and the methane production was significantly positively correlated with dehydrogenase(R^2=0.847,P<0.01).
