| 摘 要： | 研究了微磁场条件下pH冲击对处理低负荷葡萄糖废水的微氧活性污泥表面性质的影响。在pH=6.0和9.0的条件下对添加磁粉和无磁粉反应器微氧活性污泥进行15 d的冲击,而后调整pH=7.5进行5 d的恢复实验。对pH冲击下污泥絮凝能力FA、疏水性RH和表面电荷SC的变化情况进行考察,结果表明,有磁粉反应器的各项指标均优于无磁粉反应器。经过5 d的恢复实验,添加磁粉反应器污泥的各指标均能恢复到接近初始值,而无磁粉反应器污泥难以恢复到接近初始值。

| Abstract: | Under weak magnetic field, the effect of pH shock on the surface characters of the micro-aerobic activated sludge used to deal with low load glucose wastewater was studied. The micro-aerobic activated sludges in the reactor with magnetic powder and the reactor without magnetic powder, were shocked for 15 days at pH=6.0 and 9.0, respectively. Then the recovery experiments were taken at pH=7.5 for 5 days. After the micro-aerobic activated sludge was shocked, flocculating ability(FA), relative hydrophobicity(RH) and surface charge (SC) of the sludge were analyzed. And the results showed that all the indicators of the reactors with magnetic powder were superior to that of the reactor without magnetic powder. After the 5 days' recovery experiments, the sludge indicators in the reactor with magnetic powder recovered to the original value, while the sludge indicators in the reactor without magnetic powder could not recover to the original value. |
