| 摘 要： | 对经过长期培养驯化的以NO-2-N为电子受体的反硝化聚磷污泥进行静态烧杯试验,研究了MLSS和温度等因素对反硝化除磷系统处理效果的影响。结果表明,MLSS浓度过高或过低都会影响系统对PO34--P的去除效果,MLSS为4 000 mg/L左右时,系统的除磷效果最佳。系统运行的最佳温度为20℃左右,此时系统对PO34--P的去除率达到了89.14%。

| Abstract: | Based on static beaker testing of phosphorus sludge of the long - term raise domestication denitrification with NO2^- - N as the electron acceptor, influences of MESS and temperature on denitrifying dephosphatation system were studied. The results show that higher or lower MLSS concentration can influence the PO4^3- - P removal effect. When the MLSS concentration is about 4 000 mg/L, phosphorus removal rate is the highest. When the operation temperature is about 20 ℃,the removal rate of PO3^4- - P can reach 89.14%. |
