摘　　要：在生活污水中投加自制生物球,研究了不同生物球数量对植物—生物膜氧化沟净化污水的影响,结果表明:生物球的投加促进了处理系统对污水中COD、TP、TN和NH4+-N的去除,其中投加20个生物球处理系统的COD、TP、TN和NH4+-N去除率分别为69.95%、50.73%、37.78%、37.6%,投加10个生物球处理系统分别为58.7%、41.04%、31.95%、28.75%;同时还表明,增加生物球的投加数量可以增加悬浮生长的活性污泥与附着生长的生物膜的协同作用,从而增强植物-生物膜氧化沟对污染物的去除效率。In this paper, effect of the amounts of biology-ball was studied on the wastewater purification in the Plantbiofilm Oxidation Ditch （PBFOD）by home-made biology-ball putted in the system. The results show that the pollutants removal efficiencies were also improved with the addition of biology-balls into the system. The average removal rate of COD, TP, TN and NH4^＋-N reached up to 69.95%, 50.73%, 37.78% and 37.6%, respectively, when the amounts of biology-ball reached up to 20 in the system. When the amounts of biology-ball were 10 in the system, the average removal rate of COD, TP, TN and NH4^＋-N reached up to 58.7%, 41.04%, 31.95% and 28.75%, respectively. The suspended and attached activated sludge biomass could increase with the added amounts of biology-balls, which could accelerate the pollutants removals.
