| 摘 要： | 以季铵化合物中最具潜在影响力、毒性较大的苄基季铵盐(BAC)为模型物,进行了BAC对好氧活性污泥吸附Ni2+的影响研究.结果表明,当反应液初始pH≤3时,不同浓度的BAC对好氧活性污泥吸附Ni2+的影响较小,当初始pH在3～9时,不同浓度的BAC对Ni2+吸附的抑制影响顺序为100 mg/L＞20 mg/L＞0 mg/...

| Abstract: | The benzalkonium chlorides(BAC) was selected as representative quaternary ammonium compounds(QACs) to investigate the effect of QACs on adsorption characters of Ni2+ onto activated aerobic sludge.It was showed that when initial pH was less than 3,the adsorption capacity of Ni2+ onto activated aerobic sludge was low and scarcely correlated with the BAC concentration;when initial pH was ranged 3-9,the influence of different concentrated BAC on adsorption capacity followed the order of 100 mg/L>20 mg/L>0 mg/L.... |
