高径比对生活污水好氧颗粒污泥系统的影响
|
摘要
采用3组高径比分别为3:1,4.5:1和6:1的SBR反应器(R1,R2,R3),以实际生活污水为进水并接种污水处理厂二沉池的回流污泥,研究SBR高径比对生活污水好氧颗粒污泥形成,同步去除碳,氮,磷性能的影响.结果表明,R1,R2,R3分别历时42,35和28d启动成功;颗粒污泥培养成熟后,其平均粒径逐渐趋于稳定,分别可达750,900,1100μm.启动阶段,R1,R2,R3对总氮的去除率分别为66%,61%,62%;颗粒污泥成熟后,R1,R2和R3出水均满足《城镇污水处理厂污染物排放标准》一级A标准,总氮去除率分别为79%,85%,91%,总磷去除率分别为91%,93%,94%,COD去除率分别为89%,92%,93%.进一步分析表明,在本试验研究范围内,SBR高径比增大有利于好氧颗粒污泥的形成,且利于增大颗粒粒径,进而提高沉淀性能和同步去除碳,氮,磷的性能.
Three column Sequencing Batch Reactor(SBR)(R1, R2, R3) with reactor height/diameter ratio of 3:1, 4.5:1 and 6:1 were used in this experiment. The actual domestic sewage was taken as influent and inoculate the sludge returned from the secondary sedimentation tank of the sewage treatment plant. Study the impact of SBR height/diameter ratio on the formation,nitrogen and phosphorus removal and decarburization of aerobic granular sludge in domestic sewage. The results showed that R1, R2, R3 are started successfully with 42,35 and 28 d respectively. The average size of the aerobic granular sludge in R1, R2 and R3 are 750, 900 and 1100μm when the granules have matured. In the start-up stage, The removal rates of TN of R1, R2 and R3 are 66%, 61% and 62%, respectively. After the granular sludge matured, the effluent of R1, R2 and R3 all reachesⅠA standard of the Urban Sewage Treatment Plant Pollutant Discharge Standard of China, and the removal rates of TN, TP and COD are 79%, 85% and 91%, 91%, 93% and 94% and 89%, 92% and 93% respectively. Further analysis shows that within the scope of this experimental study, the increase of SBR height/diameter ratio is beneficial to the formation of aerobic granular sludge and increasing the size, so that the precipitation performance and the simultaneous, nitrogen and phosphorus removal performance improved.
