丝瓜络填料SBBR对生活污水脱氮除磷的试验研究

Nitrogen and phosphorus removal of domestic sewage using luffa cylindrical sponge carrier sequencing batch biofilm reactor

利用丝瓜络填料序批式生物膜反应器(LS-SBBR)处理生活污水,研究了反应器对生活污水中NH3-N、TN、TP的去除效果以及生物相的变化情况等。试验结果表明:丝瓜络填料SBBR对生活污水中NH3-N、TN、TP的平均去除率分别为90%、78%、88%。说明丝瓜络填料SBBR适用于生活污水的脱氮除磷。

Luffa cylindrical sponge carrier sequencing batch biofilm reactor（LS-SBBR） has been used for treating domestic wastewater. The removing effects of the reactor on NH3-N ,TN ,TP in domestic water are studied. The re- sults show that the average removal rates of NH3-N ,TN and TP reach 90% ,78% and 88% respectively,indicating that the luffa cylindrical sponge carrier SBBR is very suitable for the removal of nitrogen and phosphorus from do- mestic sewage.
