摘要:研究了葡萄糖浓度对微氧磁性活性污泥系统降解五氯酚(PCP)的影响,并以微氧活性污泥系统作为对照。考察了葡萄糖浓度对PCP和CODCr去除率、微生物活性以及污泥理化特性的影响。结果表明,与微氧活性污泥系统相比,在所考察的葡萄糖浓度范围,微氧磁性活性污泥系统的PCP和CODCr去除率均较高,当葡萄糖浓度为1600 mg/L时,PCP和CODCr的去除率分别接近90%和75%,而无磁粉对照组的为70%和65%左右。由于磁粉的存在,微氧磁性活性污泥系统中微生物活性和絮凝性能均得到增强,当葡萄糖浓度为3200 mg/L时，脱氢酶活性最高达288.5 mg TF/L·h,而无磁粉对照组为198.4 mg TF/L·h。
Abstract:Effect of supplemental carbon source concentration on PCP degradation by micro aerobic magnetic activated sludge was studied, and the micro-aerobic activated sludge without magnetic was used as blank control. The variations of PCP and CODCr removal efficiencies, the microbial activity and flocculation performance of the activated sludge were researched. The results showed that PCP and CODCr removal efficiencies of micro-aerobic magnetic activated sludge were 90% and 75% respectively higher than 70% and 65% of the blank control, when the carbon source concentration was 1600 mg/L. The microbial activity and the sludge flocculation performance in the micro-aerobic magnetic activated sludge system were enhanced by the presence of magnetic powders, the highest dehydrogenase activity was 288.5 mg TF/L·h, compared with 198.4 mg TF/L·h of the blank control．
