网板对好氧颗粒污泥形成与性能影响的试验研究

摘要

在序批式反应器中,水平放置孔径8 mm、直径68 mm的网板,利用网板改变流体条件,成功培养出稳定均匀的好氧颗粒污泥.研究网板对好氧颗粒污泥形成及性能的影响,并考察常温下颗粒污泥对COD、NH4 +-N、TP的去除性能,分别为90％、87％、83％,去除效果较好.%A sequencing batch reactor was used in the experiment,in which the pore (8 mm in diameter) plates (68 mm in diameter) were placed in a horizontal way. By changing the conditions of hydromechanics, stable and uniform aerobic granular sludge was cultured successfully. The impact of pore plates on the formation and performances of aerobic granular sludge was studied at room temperature. The removal rate of aerobic granular sludge was tested,for COD,the removal effect was 90% ;for NH4 + N,87% ;for TP,83%.
