| 摘 要： | 试验研究了在SMBR中投加不同量氢氧化铁对出水水质以及膜污染的影响。结果表明,生物铁-SMBR中随氢氧化铁投加量的增加,COD出水及去除率略有提高;氢氧化铁投加量为5%时,对活性污泥的活性促进作用最强;活性污泥SVI的降低主要是氢氧化铁絮体本身的化学絮凝作用所致;试验条件下氢氧化铁最佳投加量为混合液污泥浓度的5%时,半透膜压增长最慢,膜污染程度最轻。

| Abstract: | The experiment explored the effect of different dose of Fe(OH)3 to the effluent quality and membrane fouling in the treatment of simulated municipal sewage by bioferric-SMBR.The research indicated that the removal efficiency of COD had a little improvement with increasing Fe(OH)3 dose from 0 to 10% of mix liquid sludge concentration in MBR;on the condition of 5% Fe(OH)3 dose,the activity of activated sludge promoted the strongest effect;The decrease in SVI of activated sludge was Ferric hydroxide flocs due ... |
