摘要
在不排泥的条件下,SMBR系统表现出对CODCr、NH3-N、TN、TP等指标良好且稳定的去除效果,其中TN、TP在较高的污泥浓度下才表现出较好的去除效果。通过对SMBR系统处理效果影响因素的考察,发现污泥浓度对系统的处理效果及反应器内的生物处理都有影响,因系统不排泥,随着污泥浓度的增加,系统出水的有机物含量下降,而反应器中的有机物浓度呈现先升高而后下降的趋势。
The SMBR system performed well in removal of CODCr, NH3-N, TN, TP, with no sludge withdrawal. The higher the sludge concentration, the more efficient removal of TN and TP was achieved. According to the investigation of the system affecting factors,the treatment effect of the system and biological treatment were influenced by the sludge concentration. As the system had no sludge withdrawal, with the sludge concentration increasing,the organics content of the effluent decreased,while the organics concentration firstly raised and afterwards dropped in the reactor.
