摘　　要：水力负荷较低（２－５ｍ３／ｍ２ｈ）是影响生物陶粒反应器在实际中运用推广的重要因素之一．本实验研究了不同水力负荷条件下（４ｍ３／ｍ２ｈ、７ｍ３／ｍ２ｈ）生物陶粒反应器对进水中有机物、氨氮及其它污染物的去除效果．结果表明，不同水力负荷对生物陶粒反应器处理效果没有显著影响，对ＯＣ、氨氮、ＵＶ２５４、色度和浊度去除率分别为２０％、９０％、３０％、３８％、７６％．水力负荷提高到７ｍ３／ｍ２ｈ可大大减少工程造价，促进该技术的实际运用．Low hydraulic loading(2-5m 3/m 2·h)is a key factor to influence bioceramic reactors coming into practice.The bioceramic reactors removing efficiency to organisms、ammonia nitrogen and other pollutants in different hydraulic loading(4m 3/m 2·h、7m 3/m 2·h)were studied respectively.The conclusions can be driven as followings:Hydraulic loading change from 4m 3/m 2·h to 7m 3/m 2·h has no effect on bioceramic reactors behaviour;bioceramic reactor can remove organisms、ammonia nitrogen、UV 254 、color、turbidity by 20%、90%、30%、38%、76%,respectively.The hydraulic loading raised to 7m 3/m 2·h can reduced bioceramic reactor constructions cost and facilitate its into practice.
