| 摘 要： | 针对珠江三角洲地区化工厂排出的低浓度对氯苯酚废水,研究了曝气生物填料塔对对氯苯酚的降解,并对降解效果的影响因素进行了分析。结果表明:初始浓度、溶解氧含量、停留时间和葡萄糖浓度等因素对降解效果影响显著;初始浓度<31mg/L,经过80h,对氯苯酚废水都可降至0.894mg/L以下,满足国家污水综合排放标准(1mg/L);对氯苯酚废水的适宜降解条件为:溶解氧质量含量为5～6.5mg/L、水力停留时间为5h、葡萄糖浓度为800mg/L。

| Abstract: | Aiming at low concentration parachlorophenol wastewater discharged from a chemical works in Pearl River Delta,the biodegradation efficiency of parachlorophenol by aerated bio-packing tower and influencing factors were studied.Results showed that the effect of factors including initial concentration,DO concentration,HRT and glucose concentration were significant.The wastewater could be biodegraded to 0.894mg/L with initial concentration below 31mg/L and HRT 80h,which can satisfy national criteria of 1mg/L.Optimum conditions for biodegradation of wastewater were DO 5～6.5mg/L,HRT 5h and glucose concentration 800mg/L. |
